Is your laptop broken? Are you trying to turn it on, but all you see is a blank black screen? This is a very unpleasant situation, but even in such a situation you can try to restore its functionality or at least try to determine what exactly is faulty in the laptop.

Most often, the cause of the malfunction is, but sometimes more serious malfunctions occur, which we will also consider in this article. We will begin identifying the faulty component a little later, since we need to start with other steps.

Step 1: Determining your laptop model

The first place to start is to check the manufacturer and model of your laptop. For example, HP Pavilion dv6, Acer Aspire 5520, Asus EeePC, etc. Usually, there are corresponding inscriptions on the laptop case, on the packaging box (if you have one) or in the documents (warranty card, delivery note).

This information is necessary to more accurately determine the nature of the malfunction, since laptops from different manufacturers may have different external manifestations of the malfunction.

Step 2: Check the warranty

The second thing is to try to check the warranty of your laptop. At this stage, you will also need the serial number of your device (usually located on the laptop case (bottom) or under the battery).

In the photos below, you can find an example of what the serial number looks like on laptops from various manufacturers.

This information will help in determining the warranty status of your laptop, so as not to engage in “self-medication” if your laptop is still under warranty.

You can skip this step if you are sure that your laptop is out of warranty.

How to check the warranty on a laptop? If you don't know how to check the warranty of your laptop, you can use the model and serial number your laptop.

Step 3: Determining the problem

In order to determine which laptop component is faulty, there is a system of external error code indication. For this purpose they are used LED indicators(light bulbs) power (battery charge), as well as button indicators Caps Lock And Num Lock laptop keyboard.

When you turn on the laptop, you need to pay attention to one (or more) indicators located on the Caps Lock or Num Lock buttons. These indicators (“lights”) will flash periodically. The number of repeated beeps will indicate an error code.

Where are the Caps Lock and Num Lock indicators on my laptop? If you do not know where exactly these indicators are located in your laptop model, you can use the indication of your laptop model and our technical specialists will try to help you with this.

Using the information below, you can try to determine the problem with your laptop or its faulty component. Mostly, this system codes are suitable for HP laptops manufactured from 2011 to January 2015, but it is possible that some codes will also be suitable for most laptops from other manufacturers, for example, Asus, Acer, Sony, Samsung, etc.

• CENTRAL PROCESSOR FAILURE

The central processing unit (CPU) is the main operating component of a computer. If the display indicates a malfunction central processor, then you need to contact the service center for help. You cannot solve this problem on your own. Since a malfunction in the operation of the central processor may be the result of some other, more serious malfunction. For example, incorrect laptop power modes.

• BIOS ERROR

Quite a rare malfunction. May occur when incorrect update Laptop BIOS.

Most modern laptops have BIOS protection and recovery mechanisms.

Therefore, if a BIOS operating error occurs, you may not even pay attention to the indication, because... If such an error is detected, the laptop will reboot and the recovery procedure will automatically start. When the recovery procedure is completed, the laptop will also reboot. The only thing you may notice is a longer (than usual) boot process, as well as a message on the screen that the BIOS has been restored after an error. If this error occurs periodically, you may need to update the BIOS

• MEMORY MODULE FAILURE

  If this type of error occurs, you can use the following recommendations to determine the faulty memory module:

  • Determine how many slots and memory modules are installed in your laptop. The number of slots can be from 1 to 4
  • Try removing each memory module (if there are several) from the slots one by one and installing it again
  • Try installing each memory module one by one (if there are several of them) into the slot numbered 1
    It is possible that only one of the memory modules is faulty
  • Install another similar one (with the same technical characteristics) a memory module that is known to be good.

Question: Asus X551MAV - Battery charging indicator is blinking

Hello. I am the owner of an asus x551mav-sx943b laptop. Today a problem appeared. The battery charge indicator flashes (red). Flashes when the laptop is turned on without a cord and with a cord. Does not blink when the laptop is turned off and without a cord. In Windows it says that I have 92% charge and 10 hours left (screenshot attached).
This problem doesn’t seem to bother me, but the laptop will turn off when the charge is zero, which is probably not good for the battery. Is it possible to solve this problem?

Question: ASUS X200LA - Battery charging indicator is blinking

Hello! While running on battery power, the laptop shuts down without a low battery warning and then does not charge to 100%. When charging, the indicator lights up red, then instead of turning green, it starts flashing red. The percentage of full charge gradually decreases: 87, 84, 80, etc. What could it be? Battery?

Battery: Last Full Charge (%)
During the last full charge, the battery was charged to less than 50% of its rated capacity.
Battery code ASUSTeKX200-30
Estimated capacity 33750
Last full charge 14208
Last full charge (%) 42

Answer: With such indicators, blinking indicates a battery malfunction.

Question: Asus N56V battery indicator constantly blinking

Hello forum users, please help me with advice... Asus laptop N56V, recently a problem arose - the battery charge indicator blinks almost all the time. Blinks even when the laptop is charged to 100% (battery charge information from Windows) and is running on both mains and battery power, as well as when it is turned off and connected to the network. According to the manual, it should blink when running on battery power, when the charge is less than 10%. Shortly before this, the low battery notification stopped appearing when working without a cord; the notification settings did not change. For example, in battery mode when watching movies, the computer goes into hibernation after about 40 minutes (settings = almost complete discharge batteries: battery capacity – 5%, the effect of almost complete discharge of batteries is hibernation).

The diagnostic report contains the following data:

Battery: Battery information
Battery code ASUSTeKN56--52
Manufacturer ASUSTeK
Serial number
Chemical composition of LIon
Long service life 1
Sealed 0
Number of cycles 566
Estimated capacity 56628
Last full charge 29707

2 more errors occurred, the second one somehow bothered me - I can’t understand what it’s about and how important it is.
1). CPU Usage: High CPU Usage
During the tracing process, the CPU load level was high. When CPU usage is low, the system consumes less power. To determine which applications and services are using the most CPU, check the CPU usage of individual processes.
Average usage (%) 4.48
2). Hardware power management features: Active state power management (ASPM) mode PCI Express disabled
PCI Express active power management mode (ASPM) is disabled due to known compatibility issues with this computer's hardware.

Please advise, does it make sense to calibrate the battery or is it pointless and installing a new one is a cure? Thank you very much in advance.
Olya.

Good time, dear forum users!

Please help... figure out this problem!

Brought this laptop with a problem - no charging (the charging indicator is constantly blinking, the battery does not start).
According to the client, the battery is new (ordered from the Internet).

The BATT+ voltage gives from 2.5 to 4.5V (walks) when the battery is connected (without it it is stable 4.5V).
The PQ310 key (on G) does not have the 10 volts required to open it (sort of).
The battery connector (1 and 2) has millivolts.
When contact 5 on the battery connector (BATT_TEMP) is closed with the battery removed, the BATT+ voltage is 4.5V.
There is an EN signal on the charger chip.

Answer from Esepchuk Alexey[guru]
Even on new netbooks and Dell laptops, MSI, Toshiba, Samsung, Asus, Aser, HP, Lenovo, etc. more often with operating Windows system 7 Windows 8 there is a problem with the battery charge indicator. This problem is most often solved very quickly, without third-party intervention, be it a service center or a local shop with a soldering iron. Usually a message appears in the tray, on the battery charge icon “connected not charging” “available, not charging” and some % of available charge. Solved as follows:
Start -> shutdown
Disconnecting the laptop power cord
Carefully remove the battery
Press the power button and hold it down for about twenty seconds (this procedure is without a battery in a netbook/laptop)
Remove your finger from the power button
Put the battery back
Turn on the laptop
After downloading operating system look at the battery charge icon, if the charge is low, then connect the power cord.
I hope the problem is resolved. And do not forget to remove the power cord at least occasionally when the battery is fully charged, this will help the battery last longer.
If the problem persists, download Bios update on the manufacturer's website.

Answer from Nikolay Vutkarev[newbie]
Thank you very much. Asus laptop. A similar problem of the indicator blinking and charging turned off is 83% resolved. After completing all procedures, the indicator does not blink and charging continues.

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 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:

• systemic nature ( BIOS settings, utilities);
• from interruption electrical network;
• 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 a laptop does not charge, the first thing that comes to mind is that the reason is battery wear. 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 item), the capacity drops.

If the limit is according to technical parameters 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). Software Windows 7 (8) contain 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 in the connector motherboard. 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 completely

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 inscription reads “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 fully charged. 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 in 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 modern laptops use a removable lithium ion battery, providing an average of 3-5 hours of battery life for the device.

After the battery is discharged, just connect the adapter to the computer mains power so that the battery starts charging 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:

• At battery life laptop 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 the 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! Accumulator battery has its own resource (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 connecting network adapter the charge indicator is not illuminated and charging is not proceeding, 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.
