When I turn on my laptop. HP Notebook PC does not turn on, Caps Lock flashes. What is the malfunction

Greetings, dear users!

HP DV6 Notebook PC won't turn on, what should i do? It was after one of these requests that I had an irresistible desire to write a supplementary article to help the unfortunate laptop owners. You should know that laptops are a very capricious technique, which is why it happens to them more problems than with stationary machines.

The HP Pavilion DV6 laptop does not turn on due to many reasons, moreover, these signs always appear the same, regardless of the device model. You have probably already experienced this unpleasant feeling ... sit and work, when suddenly the screen goes out and the device does not turn on for the next couple of days. In this case, you need to urgently finish the work or just have a nice time at the computer. Today I propose to take a closer look at this problem and solve it using own strength fingers.

Simple solutions

Very often, inexperienced users cannot turn on the laptop for one simple reason - their own inattention. What kind of carelessness are we talking about? Suppose your HP Pavilion DV6 laptop does not turn on, you press the power button diligently, but nothing happens. It so happens that the power indicators turn on for a couple of seconds, but the device still does not respond. Friends and just people who need help often turn to me with such questions. Imagine their surprise when I connected the power supply to the corresponding socket and everything worked! In some cases, it was necessary to remove the battery and insert it back. But more often than not, you cannot use your mini PC due to the discharged battery! That's how simple it is!

Battery and power check

First of all, we check the battery. It is because of him that the HP Pavilion laptop does not turn on and does not respond to connected charging. Remove it by connecting the charger to the laptop. If it worked, then congratulations, problem solved. Try putting the battery back in if the laptop with the battery won't start - or plugging into an outlet without a battery, which is generally not prohibited by law.

If, after checking the battery, the laptop still does not want to show signs of life, I recommend checking the power supply. If possible, replace it or check the voltage on the old one with a voltmeter. The easiest way to check if the PSU is fixed is to look at the indicator light. Usually, such an LED is found on every laptop charge.

Remember that the PSU itself may be serviceable and even respond to being connected to an outlet, however, the laptop itself may be in a dead state. It is likely that you are dealing with a damaged cable. Naturally, we need an urgent replacement.

Malfunction of the insides

The HP Pavilion laptop won't turn on even after checking the power supply, cable, battery, and although the latter does not fail as often as everything else. motherboards laptops have a solid assembly, therefore, it will not work here to find the problem module by the elimination method, as is the case with a regular PC. Unless you can take turns removing and sticking RAM dies, checking each of them separately.

The rest of the components - processor, video card, Network Card... All this is tightly soldered to the motherboard, so nothing can be done here. It's good if you noticed one of the "swollen" capacitors after taking apart the laptop, which can be replaced by an engineer friend of yours who is a master of a soldering iron. More complex power breakdowns on the motherboard are difficult to fix without the proper knowledge and tools. Most often, such fees are doomed to death. It will not be very advisable to change it in terms of the pricing policy of service centers. Better to buy a new device.

Internal dustiness

Laptops, like stationary machines, may not turn on due to excessive overheating. A failure of the cooling system is possible here, which leads to the dustiness of the insides. Yes, quite a lot of dust, dirt, hair and even bread crumbs gets under the small laptop case! All this disgrace does not allow the radiator to cool the microcircuits and the motherboard, which is why your device can turn off immediately after a couple of minutes of work. Usually, this happens, only in rare cases, the laptop does not react in any way when turned on.

So, HP Pavilion laptop won't turn on due to dirt. Carefully disassemble the case, then, with a dry cloth

HP laptop does not turn on, how to start it is the first question that arises before the owner of the device. Laptops, due to their mobility, are used much more often than desktop computers for work. They are used by students, managers, trade workers, and almost every IT specialist has his own laptop (as Americans call their laptops).

The portability of a laptop, its main advantage over desktop PCs, has become its problem area, its compactness has led to difficulties with cooling during operation, as a result, the percentage of breakdowns in laptops is higher than in other devices.

Therefore, it is always recommended to buy laptops of well-known proven brands, such as HP (Hewlett-Packard, for example, which have long established themselves in the market and which have a dense network of service centers in Russia.

Also, until the end of the expiration of the warranty service, you should not neglect the advice, keep the packaging from the laptop and the documentation for it, which indicates the warranty and the internal filling of the laptop.

The first and most common scenario is that your HP laptop won't turn on and no lights come on.

It is worth trying to turn off the Wi-Fi router to which the laptop was connected, flash drives, printers, monitors, projectors connected to the laptop. Disconnect the laptop from the wired network. If the phone was connected to the laptop via Bluetooth, you need to disconnect it too.

Perhaps the cause of the problem was a conflict in the connected peripherals. If, after the measures taken, the laptop started working, then it should be determined by the method of elimination which peripheral equipment is leading to a failure and to solve problems with this equipment, replacing the drivers, excluding their simultaneous connection of two gadgets, etc.)

If the laptop battery is discharged, you need to connect the laptop to the mains. If, after connecting to the mains, nothing has changed, the power supply is faulty (either the contacts on the power plug have come off, or the wires are bent), if you have a spare unit identical to the original. If no changes have occurred, then it makes sense to try turning it on without a battery.

This mode of operation is undesirable for laptop operation due to possible power surges in the network, so turn on your HP laptop in this mode for no more than 10-20 minutes, or work through an uninterruptible power supply or stabilizer.

Remember, perhaps, before the last turn on, you played a game with high graphics requirements for a long time or used another application that is very demanding on the video card. In any case, if such a malfunction occurs, you should contact service center... Describing in detail the "symptoms" and "history of the disease" to the master, this will greatly speed up the elimination of this laptop problem.

In this small review was considered multiple crash options when turning on HP laptop... The reasons for this may be problems in the operation of the equipment connected to the laptop, hardware faults and problems in software... But in most such cases, the cause of the malfunction is problems in hardware... Therefore, it is best to contact the service center for qualified assistance.

Our service center is an authorized representative of Hewlett-Packard and we will be happy to help you troubleshoot your notebooks. We will always be happy to provide our services, and look forward to fruitful cooperation.

When HP laptop does not turn on, you need to contact the service to make a diagnosis and find out the reason. You can eliminate some of the factors provoking such a problem yourself, but, for example, it is better to entrust the replacement of parts to the masters who will insert everything correctly. Causes may be different and it is better to make sure of the possible immediately after the diagnosis. We will look at some of them, the most common ones that we encounter every day. If you wish, you can make repairs yourself, but you should know that our specialists are always open to your requests. Notebook HP Pavilion- this is a very delicate thing, try to treat it with tenderness and understanding, because due to improper behavior with it, as well as due to blows, it ceases to function correctly and often breaks down. What to do To avoid such consequences, you should know that these are the elementary rules for operating a laptop. But if the laptop is connected, you checked everything and still no bulbs are off and he does not show signs of life, then a thorough diagnosis, professional help is needed.

Reasons why HP laptop won't turn on.

Let's see what malfunctions seriously affect the robot. HP and how best to eliminate them. For many of our clients and clients, most often the north bridge or the south bridge breaks down on their laptops. It is necessary to replace it immediately, as we do every time in this situation. Also, we will immediately find out from what the laptop squeaks and what to do. Some of our visitors also have a problem with the video chip, it stops working, does not function. In this case, the result is the same, it should be replaced with a new one. If you want to know why your device is not working, we advise you to do a free diagnosis with us. Maybe even such a small problem as not work button inclusion, which is easy to repair / replace.

Laptop does not turn on then, when it is not charging, that is, there is no electricity supply. Accordingly, in a discharged state, it cannot even boot, not that it can work. Perhaps only the power connector is broken and needs to be replaced. Do not forget that you need to do diagnostics to find out what the real breakdown is. For example, there may be a problem in the power supply, and only a check will tell you that this is exactly the case. There is a saying “Measure seven times and cut once”. Knowledge is as important in our work as in this proverb. Knowing exactly where the problem is and how to fix it so that you can use your laptop for a long time is our main task. If stopped turning on laptop, do not be nervous, perhaps the connector is torn out, or rather its contact group is damaged. Its restoration will help here, and it will continue to work as before a breakdown. With the help of diagnostics, you can accurately find out if there are problems with motherboard which also affects work HP.

HP laptop won't turn on? Do you want to know how long the repair will take?

Laptop shut down and won't turn on in different cases, we already know what the problems may be, but the time spent on fixing them is also important. In our gsmmoscow service, you will find out the exact time to repair or replace a part in your device. We will roughly tell you how much time will be spent in a particular procedure.

1. Our craftsmen will replace the video chip, the south and north bridges in about four hours. And yet, if the laptop has indicators are off- this does not mean that it is broken, check the power supply.

2. Repair of the board, provided that it is in stock (which is exactly what it is, thanks to the stocked warehouse) from two hours.

3. The replacement of the power connector will take from one hour.

We will make diagnostics of your HP from one hour and we will immediately find out why the bulb does not light up, does not turn on.

What to do if your HP laptop won't turn on - that is, after startup, you see only a blank black screen and the key light on the keyboard blinks Caps lock(or Num Lock)?

The problem with turning on the laptop, when nothing is happening on the screen, although the fan is running, is a serious cause for concern. When your HP computer fails to start, the Caps Lock light on the keyboard usually flashes for a reason. Depending on the frequency of blinking, you can define an error code that will help us to pre-diagnose the malfunction.

If the laptop does not turn on and the battery light is blinking or off, the battery may be insufficiently charged. When operating "from a wall socket", the laptop should turn on. If everything is in order with the battery, and at startup, the indicators near the Caps Lock and / or Num Lock keys flash, you need to count the number of flashes and, by their number, determine the reason. The official website of the HP company gives the following signal decoding:

Caps Lock / Num Lock	Component under test	Malfunction
Flashes once	Cpu
Flashes 2 times	BIOS	BIOS corruption
Flashes 3 times	Memory	Memory module defective
Flashes 4 times	Graphics
Flashes 5 times	Motherboard	General failure motherboard
Flashes 6 times	BIOS

But it is not always possible to reliably determine the malfunction in this way, so the laptop will have to be sent to a service center in any case. However, we will give explanations from the HP website for the listed malfunctions.

Defective central processor- everything is simple, but expensive. HP recommends contacting a service center immediately.
BIOS corruption- HP advises to wait, if this error occurs, the computer will restart and fix it itself, although this process can be very long, so you just have to be patient and just wait.
Memory module defective- if the indicator lights say the problem is random access memory, disassemble the laptop and carefully remove the memory from the slots. Put it back in and try turning on the computer again. If the situation has not changed, replace the RAM strips with new ones or contact the specialists.
Graphics controller defective- HP advises you to contact the service center immediately.
General system board failure- this is a fault for which there is no specified blinking mode of the indicator. As in the case above, you are dear to the service.
BIOS Authentication Failure- a very rare problem associated with unauthorized changes to BIOS settings or their mismatch with the hardware platform.

Common problem in HP Pavilion dv6 - Caps Lock flashes

A common malfunction in laptops deserves special mention. The American company in this series of laptops frankly messed up with a cooling system, which is why the devices get very hot during operation. Earlier, we have already considered how to clean it from dust in order to lower the temperature of the system. However, this does not always save.

If pavilion dv6 does not turn on, and the caps lock indicator flashes once, hinting at a processor malfunction, the problem with a high degree of probability may be in the graphics adapter, which also does not bode well, and the main thing here is to decide where and how to repair the laptop. If the diagnosis confirms the "diagnosis", the cost of replacing a video chip or the entire system board can be up to half the price of a new computer. However, you will certainly be offered a cheaper repair method - heating the chip. This method can be called artisanal, but it works and is relatively cheap. True, no one will give a guarantee for the long-term performance of a laptop.

It was the same with my HP laptop, the instructions from the official HP support site helped, there were no repairs.
http://h10025.www1.hp.com/ewfrf/wc/document?cc=ru&lc=ru&dlc=ru&docname=c01993145

After four years of faithful service, my dv6 is also covered. It did not turn on, the caps lock blinked once. I went to the HP website, checked the symptoms and thought "definitely a processor."

I have already found the required percentage in my city, but nevertheless I decided to go to a familiar IP repairing computers. He immediately pronounced another verdict - the problem is not with the process, but with the vidyuha. We decided to do everything as cheaply as possible - warmed up the chip, gave it $ 50. The laptop has been working normally for a month, although no one can give a guarantee here, as luck would have it.

I'm fucking hot for 5 bucks, for 50 you can change it yourself to a new one)))

Thanks for the site, I cleaned the RAM, blinked 3 times, and everything worked, although after starting I immediately changed the OS. Thank you!

I have such a problem, the laptop was lying for 2 months, then I turn it on and ... .. Only the caps-lock flashes, constantly every 2 seconds. what can you tell me please.

The lights next to the Caps Lock and Num Lock keys flash when an error is detected during startup. The indicators flash a certain number of times in a row and then go out. The number of flashes in the sequence indicates which component caused the error when tested during the initial check. If the lights stop flashing and the computer does not start, you can press the power button again to re-run the test. Count the number of flashes and determine the cause of the error using the table.
1. What if both lights are blinking constantly?

I had the same problem, just the memory bar is either badly worth it or xs .. the problem was solved, I just put the memory bar in another slot and the laptop started up ... so try it all without repairs ...

A similar problem with an HP dv6 laptop, after turning on the screen is black, the signal is not sent to the external monitor either, Caps Lock blinks constantly at a frequency of 1 time in 2 seconds. What could be the problem?

How many times does Caps Lock flash?
1. caps lock flashes constantly! The hard disk drive indicator lights up in red. He took out the railway, started everything smoothly. They write that it should blink a certain number of times, but I have it blinking constantly! tell me what to do ?????
  
  Also, caps + num are constantly blinking at intervals of 2 seconds.
  The indicators for mute, volume, wifi and touchpad are on. The screen is dark.

Help me please. Also hp Pavilion bv6, 4.5 years old. It began to warm up, I disassembled it, right up to removing the cooler, cleaned it, as I already did. I changed the paste. Collected and ... a black screen, blinks 2 times with indicators. Disassembled / assembled several times, even launched it in a disassembled state - to no avail. They will read that this is the BIOS and you have to wait. It has been buzzing for 2.5 hours, there is no effect. Tell me what to do.

Alas, the HP support service in its instructions does not say anything more about this except that you just need to wait. It is better to take it to the service, since the blinking indicators, although they flash according to a certain scenario, cannot be diagnosed with 100% certainty.

Dmitry, unsubscribe pliz I have the same problem 3 day twisting twirling nothing helps (the model is the same)
1. Similarly, I disassembled the HP 630 with a problem - it warms up, cleaned the damped heatsink, lubricated the cooler, replaced the thermal interface, assembled everything - and oops, the laptop does not start, all 3 indicators (Power, Caps and WiFi) are blinking constantly. As a result, he took alcohol, ear cleaning, thoroughly cleaned the contacts, wiped dry - and voila, everything started! Conclusion - HP diagnostics in the firebox, because Here she indicates percentages, not memory, which can be confusing!

fixed the laptop? if so what happened!

Hello! fixed the laptop? if so what happened!

Hello, my screen is off and the caps looms constantly every 3 seconds.

Good afternoon. A video card, one of the bridges, a processor are the most likely reasons in this case.

I pulled out the battery and it started up "as if nothing had happened."

hello, there is a hp pavilion dv6-2116er laptop after 2 months of operation (did not turn off 2 months) does not turn on, the indicators are on only caps, number and the power indicator without blinking, the fan is working, after cleaning, it turned out that the south bridge is sooooo hot ( you can't even hold a finger), about the percent and the southern one, I am silent, they also warm up at a moment to boiling the water (maybe they should be warming up like that?). have any thoughts ???? I will be very grateful.

dv6 love to die after heavy loads on the schedule. By the way, did the laptop work for 2 months without shutdowns at all or was it in hibernation mode? (a nasty mode from which they often never wake up). A laptop is on the way to service; both the south and north bridges can be sentenced. They can write off for a replacement, or they can try to warm up the chip in the hope that it will come to life and work until the next critical loads.

Hello! Faced a black screen problem, the fan was working, Caps Lock blinked 2 times. All instructions from the office. site did not help. Conversation with tech support too. Advised to take to the service center. I don't know much about computers, but my intuition helped. I pulled out a small battery, as I understand it from the BIOS. The computer booted up and the BIOS settings were reset to the factory settings, then I put the battery back in place and lo and behold! My computer works as before again)))!

Thanks a lot! ! ! I also have the most caps lock f12, in general, I pulled out the battery and everything worked thanks again!

There is another option, pull out Akum, disconnect it from the power supply, hold the power button for about 10 seconds

Good day everyone!
Hp pavilion dv6-6030er laptop. When turned on, the lamp on the f12 key lights up in orange and the caps lock flashes constantly. Wherein HDD will not start and the screen will not turn on. Only the cooler starts up (starts to spin) and the dvd drive. After a while, as if nothing had happened, and always at different intervals, the laptop turns on and everything works, only always when you turn on error 502 (cmos reset), but after pressing enter, 7 starts without problems. There is one more feature. The clock is always knocked down, every time you turn it on, you have to re-adjust. After work, when the computer is turned off, interesting things also happen) The screen goes out, and the lamps in the f12 and on / off keys remain on. And so on until you lift or rearrange the laptop. Only then does it finally turn off.
I must say right away that I changed the battery 2 times.
The laptop was cleaned of dust. The thermal paste was changed.
I tried to rearrange the memory from one slot to another - it does not help, everything is the same.
When the computer is turned on tested the hard disk drive and memory. Everything is fine, no errors were found.
I drove it to antiviruses, everything is clean.
Overheating, so that there was never a shutdown of the computer.
I don't even know what to think about? Maybe the percent is covered? But on the other hand, if it has already turned on, then it can work all day without problems. Broke my whole head….
Can anyone come across such a problem?

If the date and time are lost, check the battery, replace it. If it doesn’t help, the mother’s problems with keeping the BIOS parameters!

laptop povilion dv7 flashes 1 time caps lock.
very rarely, but it happens that it turns on, what can be?

hp 630. Caps flashes 11 times, then it is cut down, after reboot the same thing. What to do???

I have such an interesting problem HP dv7-1270oe laptop I turn on the laptop everything works except the screen and blinks every 3 seconds Caps Lock and num lock without ends. What could be the reason?

I have an HP pavilion dv6 laptop, too, the capslok blinks and f 12 is on, handed over for diagnostics, did not find the reason, then I started it at home by holding clrl + alt + esc_ right now I'll try to reinstall Windows what happens

The same problem as for all of the above unsubscribed - it starts, the screen is dark, the caps are constantly flashing at intervals, etc. in the same vein ... Buku is already 5 years old, dv6-3108er was at first, then the video card burned out, it was 5470 did not bother with replacing the chip, I found another motherboard from the same series from the masters for a cheap price (1500r) in terms of parameters even better than it was 5650, I don't write about the built-in, and there and there 4250.
The processor installed its own native athlon2 p340. From which model of the beech the board was, I don't know exactly the options from this series, several according to the masters, the processor was some of the phenomena. The old firewood came up to the vidyuhu and the rest, in general, the upgrade was successful.
The old board burned down after 2 years and 8 months. from about overheating (stood on the table all night, the poor shook torrents, in the morning I found a workaholic with artifacts all over the screen), replaced, apparently, even older than my own for a year, since 2009, judging by the reset in the BIOS.
According to information from the network from knowledgeable electronics repairmen, in this series of laptops there really are problems not only with cooling, as the author of the topic said, but also the use of poor-quality components in them and a direct confirmation of this by the number of negative reviews with the same problems.
I scribbled a lot here, well, maybe my scribbling will be useful to someone. I also wanted to suggest one method that helped me. All the above methods are also good, but when they stopped helping me, I just stupidly turned it on over and over again and for the thirteenth time it still starts up, so that it is clear for yourself whether it starts or not at startup, look at the indicator near the f12 button and at the indicator of the hard drive (hard disk).
If after pressing the power button, one indicator on the F12 button is on, and the second one next to it (I have a mute button) does not light up after a couple of seconds, you can not wait - a false start! - immediately forcibly turn off by long pressing the start button, by the way, the disk indicator also lights up with a constant orange color - this is also an indicator, it usually blinks white, as when reading data.
In fact, I no longer look at the disk indicator, it is located from the end and is not very convenient, the main thing for me is if both indicators light up at startup - f12 (button for turning on the Wi-Fi, bluetooth) first and f11 (button on sound) after a couple seconds.
It also happens that the laptop starts up and the screen is on, but after a few seconds it freezes - the screen is on, and the image hangs on the splash screen, and even if you enter the BIOS, it also hangs.
In this case, again forced shutdown by long pressing the start button and again. The computer at the next start usually starts up normally and boots as usual, but it happens that dances start again with turning on the shutdown until the coveted start with two burning lights occurs.
It also helped me against the brakes on the screensaver to take the laptop out to frost -10 and the start-up took place in such cases the first time and worked perfectly, as if nothing had happened.
After forced shutdown and further successful startup Windows offers: "normal start" or "run recovery tools", I always choose "normal start" and already booted I run the programs to clean and fix errors from multiple restarts.
For myself, I understand what the reason is in my device - these are two options:
either dissipate the chips of the bridges (from time to time, microcracks appear in the soldering, hence there is poor contact), and therefore blowing with special fen helps many,
or the problem of the chips themselves, because they are not of high quality and live out their five-year plan programmed by developers, with someone earlier, somewhere later.
Thank you for your attention, I expressed my thoughts, and my advice on launching can be useful to someone.
zs Experience is not a transferable thing))) ... however

Thanks for the expanded comment. Everything is just like that. It's amazing how a company with that name released such a problematic laptop, and even with such a high price tag, and the first year or two, when you can make a claim, it works flawlessly and pleases up to X hour.

Thanks for the advice! the hairdryer helped!

Thank you all for the advice. The monitor did not turn on and the caps lock was on. removed the battery and it worked. put it back and everything works again.

Good day! There was a problem after flashing BIOS on hp g62. After the firmware, the computer rebooted, and a black screen appeared (without loading the BIOS), and it was capturing the bow 2 times. Please help with the solution of this problem.

And if the same problem but the capsluk does not mete at all, the fan runs constantly

I solved this problem by reinstalling Windows.
A month has passed and everything is in order.

Hello everyone!!!
I also blinked caps lock - 1 time.
the problem was in the RAM. The memory bar was covered and changed to another - it all worked. Do not rush to give it to the service, try this method.
Good luck to everyone, let your PC do not let you down!

It flashes constantly what does it mean
