Most modern laptops use a removable lithium-ion battery, which provides an average of 3-5 hours of battery life.

After the battery is discharged, simply connect the AC adapter to the computer to start charging the battery again.

Confirmation of successful battery charging will be when the indicator lights up on the laptop panel, which, as a rule, is a small light bulb with a picture of the battery.

Under normal conditions, this indicator is illuminated in green (blue, yellow) or another neutral color, but at certain moments it may begin to blink, change color to red, or stop lighting altogether.

The color indication of the battery, as well as the intensity of its blinking, may differ depending on the brand and model of the laptop, but one thing is intuitively clear - if the charging indicator on the laptop blinks red (or orange), this warns of some kind of problem.

What does a flashing charging light mean? What to do if, when the AC adapter is connected, Laptop battery charging indicator does not light up? The answers to these and other questions are in our review.

Let's consider several situations in which the battery charging indicator may blink, including an unusual color:

• When the laptop is running autonomously The charging indicator suddenly started flashing red. There is nothing wrong with this - such an alarm indicates that the battery charge level is approaching zero, and you need to urgently shut down the work or connect the AC adapter to the device.
• The charging indicator on the laptop constantly blinks green (blue, yellow) or another neutral color. This can be observed when the device is closed but not turned off.

This indication is not a cause for concern, but only indicates that the computer is in standby mode.

• When charging the laptop, the battery indicator flashes red. If the battery charge light continues to blink red even when connected to the network via a standard charger, this indicates problems. In this case, the fault may be hidden not only in the laptop battery, but also in the power supply itself. To determine the exact cause of the breakdown, you should contact the service center.

Attention! Do not try to open and repair the battery yourself - it is unsafe! The battery has its lifespan (about 1000 charge-discharge cycles), perhaps it's time to replace the battery.

• When you connect the AC adapter, the charging indicator lights up, but the laptop does not turn on.

If the device was completely discharged before connecting to the network, you should wait a few minutes - the problem should disappear.

If the laptop sits on charge for a long time, the corresponding indicator is illuminated in the standard color, but the device does not react in any way when the power button is pressed, then there is a high probability that there are problems with the computer’s video card. Only diagnostics will determine the exact cause.

What to do if the battery charging indicator on your laptop does not light up

As a rule, in most laptop models, the battery charge indicator does not light up when the device is running on battery power.

This indicator usually starts blinking when the battery charge level drops below 10%. When approaching a critical charge level, the indicator begins to flash orange or red.

If, when you connect the AC adapter, the charge indicator does not light up and charging does not occur, you should check the contact in the laptop power supply socket - it is often broken if the device is handled carelessly. You should also pay attention to the cable - it may be damaged.

If The battery charging indicator on the laptop does not light up, but the device is charging and operating normally, you should check whether the indicator itself is working properly.

Why is the battery light blinking on my laptop?

Often inexperienced users have a question about why the battery indicator on a laptop blinks. Almost all manufacturers are required to provide battery status indicators on their models. This is necessary to inform the user about the particular state in which the battery is located. The indicators may be on, off, or flashing slowly or rapidly. Each such state indicates a certain state of the battery. Unfortunately, these LED signals on laptops can vary depending on the manufacturer and even the model. Because of this, confusion arises and it is difficult for an untrained person to understand why the battery light on his laptop is blinking.

As already mentioned, most laptop models from different manufacturers have indicators that operate in different states. Depending on the condition of the battery, the indicator may be on, off, slow or fast flashing. The indication may change depending on whether the laptop is connected to the mains or is in offline mode.

On most models, a green, purple or blue indicator light indicates that the battery has a full charge. On many models, manufacturers separately provide a laptop charging indicator, which shows that the charging process is in progress. This is usually a flashing green, purple, orange or blue indicator light.

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

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

But if the laptop battery indicator continues to blink red or orange when connected to the power supply, this may indicate problems. In this case, the fault 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 connecting to charging. It turns off only after reaching a certain battery level.

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

If you have difficulty determining the battery status using the indicator, you can look at the battery data in Windows.

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

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, but 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 point in a yellow triangle to the battery icon.

If Windows diagnoses battery problems or a critical charge level, the battery icon will have a red cross on it.

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

Start menu -> Control Panel -> Power Options. There you can select a power saving plan, set the actions of the power buttons, etc.

In general, a week ago everything was fine, now my wife turned it on but it doesn’t plow, doesn’t turn on.
I plugged in the power cord and the laptop started working, but the red lightning indicator flashed quickly, although
the charge shows 95%.
But without the power supply it won’t even turn on, and if you remove the power supply the laptop shuts down completely.
The laptop is about 4 years old and hasn't been used much. And when I turned the laptop over, there were indicators on the battery, so they were green, today they are not, I checked the battery, the light bulb from the flashlight burned out when I checked it, that is, the voltage there is normal.
Something is wrong with the laptop.

Has anyone encountered this?

After 4 years the battery died, no big deal, you can find a new one. True, there is an ambush; it can be difficult to find for a 4-year-old. I had this happen last year, I wanted to install additional RAM on my 5-year-old laptop, but I was faced with the fact that such memory is no longer produced. This was one of the reasons for purchasing a new device.

19.11.2011, 22:38

I checked the batteries, there are 6 AA batteries hidden in the battery,
The batteries work normally and are charged, in addition there is 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 gone bad, or maybe there are microcircuits in the battery itself.
Does it turn on without a battery?

20.11.2011, 09:57

Does it turn on without a battery?
Is it at least difficult to write a notic model or is it designed for telepaths or megagurus from notation?

Without batteries it turns on and works, the indicator does not blink, as soon as the battery is plugged in the red arrow blinks.

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

20.11.2011, 10:51

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

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

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

And the fact that the banks inside are charged, so the Meyans 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 only contains 150 mAh from the original capacity of 1500 mAh.

20.11.2011, 11:33

I'll try Everest. But even the indicators on the battery show that the battery is charged; there is also a button on the zipper, apparently for some kind of reboot.
If you press it, three indicators flash one after another.

The battery has indicators, look here

Http://www.techlabs.by/img/img/190731.jpg
So I have them all completely green.

Once again: did you disassemble the battery? did you see the microchip inside? This is a battery controller, it also monitors the actual capacity of the battery in order to prevent it from being overcharged and discharged too deeply. And that’s what lights up these indicators, which are completely green...
95% charge relative to what does the indicator in the tray show you? relative to the nameplate capacity of the battery or relative to its real capacity, which has dropped 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 radio tubes, so here’s about it: both the radio tube and the intelligent charger show that the battery is charged. And it charges normally, for all its 150 mAh, with a current of 200 mA in just over an hour. And it discharges with the same current of 200 mA in a little less than an hour, which is quite consistent with its actual measured capacity. And not a passport.....

The battery has indicators, look here
So I have them all completely green.
Perhaps one of the cans is covered (not charging), so no problem. shows normal voltage, but at the slightest load the voltage drops - the controller turns off the battery.
Check each jar separately with a voltmeter when connecting a small load.

20.11.2011, 12:55

This is a Dell disease, it can be treated by disabling the power adapter and battery 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 take out the battery, it will stop blinking.
It blinks even when the laptop is turned off. Flashing speed is approximately 100 per minute.

Now I installed the baterry eater program
Here's the screenshot.

In the BIOS there is also 95% charge. And no one knows how to reset the battery to factory data..

20.11.2011, 14:24

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

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 the Everest report:
Power supply

Power properties:
Current power source Battery
Battery status 54% (Unknown)
Total battery life Unknown
Remaining battery life 4986 sec (1 hour, 23 min, 6 sec)

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

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

Does it really take that long to download Everest and launch it??

Laptop power failure occurs for various reasons. Sometimes the question of why the battery on a laptop does not charge can only be answered by a specialist. However, before the service center begins to solve the problem, you need to independently check the serviceability using simple manipulations.

Laptop battery does not charge - reasons

The laptop battery is not always the reason for the lack of charging. Practice shows that the reasons may be:

• system nature (BIOS settings, utilities);
• from a power outage;
• from poor contact in the charging circuit (socket, cord, power supply or AC adapter);
• during oxidation of battery contacts;
• from a faulty power connector.

Physical deterioration

When your laptop won't charge, the first thing that comes to mind is that the battery is worn out. However, this statement is only true when the device is in service for the 2nd or 3rd year. The performance of the battery of each laptop is determined by its manufacturer, the installed capacity and frequency of operation. Standard service life is 2-3 years, or 800 charging cycles. After this (the battery is a consumable element), the capacity drops.

If the limit according to the technical parameters is exhausted, then you can replace the consumable with complete confidence. Where to put the old one, read the manual in the “Disposal” section. Before doing this, rule out other causes and conduct an analysis using the Battery Health program for iOS (free). 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 does not charge may be due to the power supply. It is necessary to check the functionality of the outlet. If power does not appear, follow the chain:

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

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

Procedure:

1. Replace the cord with another one, or sequentially move it to the power supply, and monitor the charging indicator. If you can find a break in it, replace it; if not, proceed further.
2. Follow the same principle with the power supply. If there is a similar converter for volt output, then rearrange it and check for charging on the indicator. If not, contact your 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 blinking, then the reason is in this gap in the circuit, and you need to contact a specialist.

Doesn't charge fully

In models such as Acer, Asus, Dell, Lenovo, Samsung, Asus, the answer to why the battery on a laptop does not charge may be some features of the software from the manufacturer. The situation why the laptop does not charge completely 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 stops 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 to the laptop;
   • unplug the power supply from the outlet;
   • remove 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 the operating system settings (Restore Defaults) and save the bios (Save and Exit);
   • turn off with 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;
   • We check the presence and operation of the indicator in the tray.

If the sign says “Connected and charging,” then everything is in order, if the laptop is not charging, go to step 2. Very often, in order to ensure maximum battery life, the manufacturer installs utilities at an affordable level (70–80%), which prevents full charging . Procedure:

1. Checking utilities:
   • go to the dispatcher (manager) for managing the battery mode;
   • enable the “Optimal battery life” mode;
   • save the setting.
2. In cases where the laptop does not charge, but works from the network, it is necessary to replace the battery or check the functionality of the power board (only at a service center). Please note a few points:
3. if the battery contacts, when oxidized, prevent the supply of charge, then the solution is to clean them;
4. The battery must be properly seated in the laptop.

Most laptops use a series of lights to indicate the state of the computer.

Each indicator has several states, such as on, off, slow flashing or fast flashing.

They can also switch between different colors (much depends on the model).

Each computer manufacturer uses its own codes to indicate the charging status of a laptop, but there are some common features.

NOTE: If you have problems with the charge indicator, the first thing I recommend is to calibrate the battery. How?

Charger

Most laptops show a green, blue or purple light to indicate that the battery is fully charged.

Many manufacturers indicate that a laptop is in the process of charging by showing a steady or flashing green, orange, blue or purple light.

If the battery light is green, blue or purple, then the battery is functional, regardless of whether the light is flashing color or not.

If the light is orange, the laptop is most likely charging.

Battery error

Many battery manufacturers use flashing lights to indicate that the battery's charge level is low.

In general, a laptop will quickly flash orange or red when its charge drops below a certain level while the computer is not plugged in.

If your laptop's battery light keeps flashing orange or red quickly, or if it stays red even when it's plugged into the charger, this indicates a problem with your battery or charger.

Windows charging indicator

If you're not sure what the light means, you can check your computer's charging status in Windows.

Look for the battery icon in the notification area of ​​the taskbar. If the display icon shows an electrical connector on the battery, then it is currently charging or is fully charged.

If there is no electrical plug and your computer is connected to the charger, then there may be a problem with the charger or battery.

A red "X" on the battery icon will appear on the screen when Windows detects battery problems.

Hover your mouse over the icon to view the current battery level. Then a tooltip will appear with information about the current charge level and charge status.

Reset

If your laptop battery is not charging, you can solve this problem by doing a hard reset. Turn off the computer, disconnect it from the charger and remove the battery.

Follow your computer manufacturer's instructions to remove the battery.

On some computers, you may need to hold down the computer's power button for 30 seconds to reset the battery status information.

Install the battery, connect the charger, and turn on the laptop.

Battery Replacement

Over time, some batteries lose their ability to receive or hold a charge.

If your laptop battery refuses to charge, even after removal and reinstallation, you may need to purchase a new battery.

If your laptop is under warranty, or your computer manufacturer has issued a recall on your computer's batteries, you may be able to get a new battery for free. Good luck.
