Every laptop owner knows that this laptop is equipped with an indicator light option. The charging light and other indicators are set as small LED lights that indicate the status of the battery, hard drive or processor. The health of the laptop battery and its performance depends on how the battery charging lamp is lit. It is important to learn how to properly understand these signals - often the color can change its meaning depending on the laptop model.

Flashing charging light

The general signals given by the light indicator responsible for information about the state of the battery look about the same. The differences in color and its meanings for different laptops will be discussed a little later.

Typically, the light flashes in the following colors, and each of them has the following designation:

• Flashing red- don't worry, it's all right. But the laptop battery is almost dead, and it needs to be charged urgently. Otherwise, the laptop will simply shut down. In this case, the operating system installed on your computer will definitely display a message that you need to connect the charger.
• Flashing green/blue - also everything is fine, it means nothing more than a standby mode. It is observed when the laptop lid is in the closed position.
• Lights up light green / blue, does not go out, burns steadily - means that the battery is fully charged, or the computer takes electricity not from the battery, but from the mains supply.
• The light on the laptop flashes when the charger is connected to the computer, red or orange. Sometimes it starts to blink, and then it goes out. This is a wake-up call that can mean anything from serious problems with the charger to battery failure. In this case, it is recommended to contact the service center, or try to fix the problem yourself - by accessing the operating system of your laptop.

Is it possible to fix the problem

The main thing - do not skip messages issued by the operating system , which monitors battery life as well. When there are problems with the battery, the OS sends a message about its damage - as a rule, it "creeps out" on the right. If the system does not display such a message and “thinks” that everything is fine with the battery pack, most likely there are problems in the charger itself.

It is important to keep in mind that if the battery is damaged, it is no longer possible to repair it. In the best case, it will either have to be completely changed, or a partial replacement of the elements will be carried out.

Charging can simply be disassembled into parts and make a dial with a multimeter. Most likely, the wiring has frayed, or the contacts have come off - this problem can be fixed with your own hands. However, if the capacitor burns out, you will have to look for a new, suitable charger.

Indicator signals of popular laptop models

In order for users to be able to at least partially navigate the “language” of indicator lamps, you can familiarize yourself with the most common colors that light up the battery charging lamp of a laptop:

• Asus. If the light turns solid green, the battery is approximately 100 percent charged. If its color changes to orange, the battery charge level gradually becomes lower. If the computer is running on battery power but is about 10 percent charged, the light may turn off. If the battery reaches a critical level, the indicator flashes orange.
• Acer. If the light turns green, the computer is on mains power. When the color changes to yellow, it means that the battery is currently being charged.
• Dell. Green color indicates the battery is charging. If the green flashes, this means that the charging process is complete. Flashing orange light - the charge level is decreasing, and if it is lit in a steady orange tone - the battery charge is critically low.
• Sony. The steady burning of the orange indicator indicates the process of charging the battery, the flashing of the same light indicates the completion of charging. Rapid flashing of the orange indicator indicates a faulty battery or that it is incorrectly installed in the battery pack.
• Samsung. A steady green glow of the indicator indicates a fully charged battery, yellow indicates that charging is in progress. If the indicator flashes quickly, the battery is bad.

In some cases, the red color of the indicator remains on after the laptop has been connected to the network. It changes to green only when the battery reaches a certain charge level. When the light is flashing, but there is no charging progress, always pay attention to the panel icons of your operating system. When the battery is discharged below 60 percent, the battery icon will be supplemented with an exclamation mark placed in a yellow triangle. If the battery discharge is critical, wait for the appearance of a cross enclosed in a red circle.

Thus, the simple signals of the indicator light will help you navigate the current operating state of the laptop battery, and in the event of alarms, you can decide in advance whether to repair the battery or its possible complete replacement.

Foreword from the author. Unfortunately, there is very little concrete information. When writing this article, I had to collect data piece by piece from different forums. I do not guarantee 100% accuracy of the information, and you should not take it as a basis for action. If you have something to add to the article, or you find an error, send your materials to the email address

1. Signal: The battery indicator flashes red (yellow) 4 times, then blue 1 time. This is repeated cyclically.
Symptoms: Laptop battery not charging. This message is shown by the laptop when running on mains when the battery is inserted. At this point, if you turn off the power from the network, the laptop will turn off.
Laptop: Dell inspiron 1300, Dell inspiron 1525 and other models.
Causes: It is likely that your battery (accumulator) has failed. This could be due to the fact that you have been working from the network for a long time with the battery inserted into the laptop.
Tips: There can be many reasons for this problem. To analyze the battery, use the Everest program. Sometimes, when the battery is not charging properly, it needs to be calibrated. If during diagnostics by the Everest program it showed that the battery is fully charged to 100% in 5 minutes, then the batteries themselves are probably broken. They will have to be changed, or buy a new battery.

2. Signal: When the power supply is connected, the battery indicator on the laptop blinks 1 time green for a long time, 3 times orange quickly. This is repeated in a circle.
Symptoms: The battery is not charging. Windows shows 0% charge. When the battery is disconnected, the laptop turns off.
Laptop: Dell D600, Dell Latitude D510, Dell inspiron 1300 and other models.
Solution: change the battery to a new one. Your battery is dead.

3. Signal: The battery indicator flashes red.
Symptoms: Without a battery, the blinking disappears, everything works as usual, but as soon as it is reinserted, the indicator immediately starts blinking again. In the notification area, the icon displays mains power, but does not indicate battery charging.
Laptop: Dell Inspiron 1300 and other models.
Solution: change the battery, as she was out of order.

In general, a week ago everything was fine, right now the wife turned it on and he does not plow, does not turn on.
I plugged in the power cord, the laptop worked, but the red lightning of the indicator flashes quickly, although
the charge shows 95%.
But without a power supply, it does not even turn on, and if you remove the power supply, the laptop is cut down completely.
The laptop is about 4 years old and has barely worked. And when I turned the laptop over, there are indicators on the battery, so they were green, they don’t light today, I checked the battery, my flashlight bulb burned out when I checked, that is, the voltage there is normal.
Something with the laptop.

Nobody faced?

For 4 years the battery died, it's okay, you can find a new one. True, there is an ambush, for a 4-year-old it can be difficult to find. I had this last year, I wanted to put additional RAM on my 5-year-old laptop, I was faced with the fact that they no longer produce such memory. This was one of the reasons for buying a new apparatus.

I checked the batteries, there are 6 AA batteries hidden in the battery,
Batteries are working properly and charged, plus a battery monitoring program
shows a charge of $95 and the battery in the corner of the tray shows a full charge.
Maybe the circuit in the laptop has flown or there are also microcircuits in the battery itself.
Does it turn on without a battery?

20.11.2011, 09:57

Does it turn on without a battery?
And at least it’s hard to write a notic model, or is it based on telepaths or a megaguru from notes?

Without batteries, it turns on and works, the indicator does not blink, as soon as the battery was inserted, the red arrow blinked.

well, yes, the battery controller considers that the capacity has dropped to, say, 50 mAh, and that the battery is charged at 95% of this capacity, and the light is blinking because it is less than, for example, 5% of the full capacity of the battery.

20.11.2011, 10:51

I don’t know about you, but in Kharkov we have a service in one store, they test lithium-floor and lithium-ion batteries and you can find out their real capacity.

In your case, I already wrote about everest above, it allows you to read the remaining capacity from the controller.

And the fact that the banks are charged inside, so I had a battery standing in the radio tube, if you measure the voltage, it’s charged, and if you discharge it to a load, it has only 150mAh from the original capacity of 1500mAh.

20.11.2011, 11:33

I'll try Everest. But the fact that the battery is charged is shown even by the indicators on the battery, the button is still on the zipper, apparently for some kind of reboot.
If you press it, the indicators flash three pieces through one.

The battery has indicators

http://www.techlabs.by/img/img/190731.jpg
So here they are all green.

Once again: did you disassemble the battery? Did you see the microchip inside? this is a battery controller, it monitors, among other things, the real capacity of the battery in order to prevent it from being overcharged and too deep discharged. And that is what lights these indicators, which you have completely green ...
95% of the charge relative to what does the indicator in the tray show you? Relative to the passport capacity of the battery or relative to its real capacity, which has fallen significantly over 4 years?
And these indicators that you have are completely green, what do they show? charge relative to what??

I wrote above about the battery in the radio tubes, and so about it: both the radio tube and the intellectual charging show that the battery is charged. And it charges normally, for all its 150 mAh, with a current of 200 mA for a little over an hour. And his discharge with the same current of 200 mA is a little less than an hour, which is quite consistent with his actual measured capacity. Not a passport...

So here they are all green.
Perhaps one of the cans was covered (not charging), so on x.x. shows normal voltage, and at the slightest load, the voltage drops - the controller cuts down the acc.
Check each jar separately with a voltmeter when connecting a small load.

20.11.2011, 12:55

This is a Dell disease, it is treated by disabling the power supply and battery adapter in the device manager.
So if I turn it off, the indicator on the laptop case will still blink, so this does not solve the problem, if I just remove the battery, it will stop blinking.
It blinks even when the laptop is turned off. Flashing speed is about 100 per minute.

Now I installed the battery eater program
Here is the screenshot.

Bios is also 95% charged. And no one knows how to reset the battery to the factory data ..

20.11.2011, 14:24

Most likely the controllers in the battery are either blocked or covered.
And I can’t check the capacity today, I don’t have a tester, I’ll buy it tomorrow and check it.

And how do you check the battery capacity with a tester ?? will control the current through the load and the voltage at the terminals?

By the way, I found an Everest report:
Power supply

Power supply properties:
Current power supply Battery
Battery Status 54% (Unknown)
Total Battery Life Unknown
Remaining battery life 4986 seconds (1 hour, 23 minutes, 6 seconds)

Battery properties:
Device name 1001PX
Manufacturer ASUS
ASUS1001PX ID
Battery type Rechargeable Li-Ion
Nameplate capacity 23220 mWh
Capacity when fully charged 20736 mWh
Current capacity 11264 mWh (54%)
Supply voltage 10699 mV
Wear rate 10%
Discharging status
Discharge rate 8132 mW

If you recalculate, then 54% of 23220 is 12538.8, and of 20736 - 11197.44, which is much closer to the current capacity.
So apparently in your case, 95% is considered from "Capacity when fully charged", and not from "Passport capacity".

Is it really so long to download Everest and run it??

Why is the battery light blinking on my laptop

Often, inexperienced users have a question about why the battery indicator on a laptop is flashing. Almost all manufacturers without fail make battery status indicators on their models. This is necessary to inform the user about a particular state in which the battery is located. The indicators can be on, off, blinking slowly or quickly. Each such state indicates a certain state of the battery. Unfortunately, these indicator signals on laptops can vary depending on the manufacturer and even model. Because of this, confusion arises and it is difficult for an unprepared person to understand why the battery indicator on his laptop is flashing.

As already mentioned, most laptop models from different manufacturers have indicators that work in different states. Depending on the condition of the battery, the indicator can be on, off, flashing slowly or quickly. The indication may change depending on whether the notebook is plugged in or offline.

On most models, a green, purple, or blue indicator light indicates that the battery is fully charged. On many models, manufacturers separately make a laptop charging indication, which shows that the charging process is in progress. This is usually a flashing green, purple, orange or blue indicator.

As a rule, if the battery indicator is green, purple or blue, then the battery is working. It doesn't matter if the indicator flashes or not. If the color is orange, then in most cases this indicates that the battery is being charged.

Notebook manufacturers most often make the battery indicator blink to inform the user that the battery is low. When the battery charge falls below a certain limit, the indicator flashes red or orange until it is connected to the network. There is nothing to worry about, the battery just needs to be charged.

But if the laptop battery indicator continues to flash red or orange when connected to the power supply, this may indicate problems. In this case, the malfunction may be hidden both in the power supply and in the laptop battery. There may be problems with the correct operation of the indicator itself. In some cases, the indicator may remain red or orange even after being connected to a charger. It turns off only after reaching a certain battery level.

Laptop battery indicator in Windows. Red cross on the battery icon.

If you're having trouble determining the battery's status using the indicator, you can view battery data in Windows.

The battery indicator is located in the system tray on the taskbar. If the icon shows an electrical plug, then at this moment the laptop is connected to the network through the power supply and the battery is in the process of charging (or fully charged). If you hold the cursor on the battery indicator in the taskbar, Windows will display information about the level of the current charge.

If you click on the battery icon, more detailed information will be displayed.

When connected to the network, an electrical plug appears next to the battery icon.

If there is no electrical plug, and the laptop is connected to the network, this indicates problems with the battery or power supply.

When the battery is discharged to a certain level, Windows will display a message about the need to charge and add an exclamation mark in a yellow triangle to the battery icon.

If Windows diagnoses a battery problem or a critical battery level, the battery icon will have a red X.

If you need to see more detailed information about the state of the laptop battery, then go to the appropriate section in the Windows control panel.

Start Menu -> Control Panel -> Power Options. There you can choose a power saving plan, set the action of the power buttons, etc.

Laptop power failure occurs for various reasons. Sometimes the question of why the battery on a laptop is not charging can only be answered by a specialist. However, before the service center starts to solve the problem, it is necessary to independently check the serviceability using simple manipulations.

Laptop battery not charging - causes

Not always a laptop battery is the reason for the lack of charging. Practice shows that the reasons can be:

• system character (BIOS settings, utilities);
• from a power outage;
• from poor contact in the charging circuit (socket, cord, power supply or AC adapter);
• when the battery contacts are oxidized;
• from a faulty power connector.

Physical deterioration

When a laptop is not charging, the first thing that comes to mind is that the battery is worn out. However, this statement is true only when the device serves the 2nd, 3rd year. The battery performance of each laptop is determined by its manufacturer, installed capacity and frequency of use. Typical service life is 2-3 years, or 800 charge cycles. After that (the battery is a consumable item), the capacity drops.

If the limit according to the technical parameters has been exhausted, then with full confidence it is possible to replace the consumable. Where to put the old one, read the manual in the "Disposal" section. Before doing this, rule out other causes, analyze using the Battery Health app for iOS (free). The Windows 7 (8) software contains the Battery Care utility, which will also allow you to determine the necessary parameters. Three main characteristics:

• rated power (declared by the manufacturer);
• maximum power (current);
• physical deterioration.

Poor battery power supply

The reason why the battery on laptops is not charging may be hidden in the power supply. It is necessary to check the functionality of the outlet. If power does not appear, follow the chain:

1. check cord;
2. check the power supply;
3. examine the power connection socket;
4. measure the mains voltage.

What to do if the laptop does not charge from the charger

Procedure:

1. Replace the cord with another, or successively shifting to the power supply, follow the charging indicator. If you can find a gap in it - replace it, if not - follow on.
2. Follow the same principle with the power supply. If there is a similar volt output converter, then rearrange and check for charging on the indicator. If not, contact the service center.
3. It is necessary to move the end of the power supply plug to the motherboard in the connector. If the light starts flashing, then the reason is at this interval of the circuit, and you need to contact a specialist.

Not fully charged

In models such as Acer, Asus, Dell, Lenovo, Samsung, Asus, the answer to why the battery on a laptop is not charging may be some features of the software stuffing from the manufacturer. The situation, why the laptop is not fully charged, can occur in two scenarios:

1. When the battery is not visible, but charging is in progress. Reason: in the controller; Solution: replace the battery.
2. When the battery indicator is visible, it stopped showing the charge, but there is no charging. As a rule, such a battery has previously been charged.

Solutions for the second point:

1. Reset BIOS settings:
   • turn off the power of the laptop;
   • unplug the power supply from the outlet;
   • take out the battery;
   • hold the power button for 1 minute;
   • connect the laptop to power without a battery;
   • enter the BIOS (using the Del, F12 or F2 key combination or following the user manual);
   • reset operating system settings (Restore Defaults) and save bios, (Save and Exit);
   • turn off the power button (hold for 5-7 seconds);
   • turn off the power supply;
   • install the battery;
   • connect the cord to the outlet;
   • turn on the device;
   • check the presence and operation of the indicator in the tray.

If the inscription reads “Connected and charging”, then everything is in order, if the laptop is not charging, go to step 2. Very often, the manufacturer installs accessible utilities (70-80%) to ensure maximum battery life, which prevents full charging . Procedure:

1. Utilities check:
   • go to the dispatcher (manager) for managing the battery mode;
   • turn on the "Optimal battery life" mode;
   • save the setting.
2. In cases where the laptop does not charge, but is powered by the mains, it is necessary to replace the battery or check the power board for proper operation (only at a service center). Pay attention to a few things:
3. if the battery contacts during oxidation prevent the supply of charge, then the solution is to clean them;
4. the battery must be properly seated in the laptop.
