The laptop does not charge: looking for a problem and fixing it

One of the most common malfunctions of a laptop is a non-recharging battery with a working power supply. This problem can suddenly appear even in a brand new device just brought from a supermarket. Read further a detailed analysis of common sources of damage and ways to eliminate them.

The laptop does not turn on

The most common reason why the laptop does not boot is a malfunction in the energy storage device. The battery stops holding the charge, power is not supplied and it does not allow turning on the device. A breakdown is easy to detect: in this case there is no indication button, the LEDs do not light up, and the laptop only functions when charging is on. The solution is to change or repack the battery. Damage can also be found inside the charging mechanism of the laptop. With this outcome, the gadget does not turn on either with or without charging. To check, you can connect another drive and boot the laptop. Here, only the acquisition of a new charge will help.

To avoid complications in the operation of the power connector, you must first connect the cord to the laptop, and then only plug into the outlet. This eliminates the possibility of a short-term appearance of a spark at the time of plug connection. Among other global problems there may be a broken adapter, broken contactors, BIOS firmware bug, and others.

Reference! If there is a guarantee for the equipment used, then in the circumstances of the impossibility of starting the system on your own, you should use the services of a service point.

The laptop does not charge

Often there are precedents when a perfectly working battery suddenly ceases to function normally. In this case, the laptop itself is working and charging is carried out. The universal technique is to reset the parameters in BIOS. To do this, unplug the system and remove the battery. Then hold the connection button for about one minute, then plug the wire into place and connect the equipment to electricity.

After turning on the laptop, open the BIOS in a phased combination of buttons F2, F12 and DEL. It is necessary to return the original parameters and save them. Then turn on the PC again and with the power button held down, de-energize the equipment and reinsert the drive. Soon a blinking notification will appear that the charge is installed.

Consider other problems and their solutions:

• A prompt should pop up on the screen that the battery is connected, but there is no charge. In such circumstances, you should check the power supply voltage throughout the room or point outlet.
• There is a problem with the power cable, which may twist or cause interference. In other words, there may be damage on it that is often not visible to the eye. The voltage is checked by a tester or by connecting the cord to a third-party unit. In most cases, you will have to spend money and purchase a new cable.
• The adapter disconnected. If you are sure that there are no snags with wiring, then you should take a closer look at the adapter. The sensor may burn, but this does not mean at all that the equipment is functioning correctly.
• Battery overheating. In order not to spoil the drive, the system automatically blocks its charging. If the problem is detected a couple of minutes after turning on, then the snag is hidden in the overheating of the battery.
• Software bugs. It is acceptable that the battery is still charging, but this indicator does not show. You should reboot and examine the parameters again. If illegal software for administering the power mechanism has been downloaded, you need to remove it and check the accuracy of ACPI. To do this, in the task manager, find the section on batteries. If the specified item is not present, then this already indicates a hardware defect in the links or connectors.

Why the new laptop battery does not charge

A newly purchased appliance is subject to a standardized license. In such circumstances, the battery does not charge due to a manufacturing defect or erroneous battery recognition. It is better to eliminate the inconsistency in the proposed way:

1. disconnect the gadget from the mains;
2. remove the drive;
3. press the main button for about twenty seconds;
4. put the battery back;
5. connect the charging and make sure that the launch is correct.

If the equipment has a removable battery, you should completely turn off charging and remove the drive from your box. Next, hold the power key for one minute. Then put the battery in place, turn on the charging and after 15 minutes, start the device. You can also turn off charging at a working device, and leave the battery alone. The power button is held until the device is completely turned off and the power module is started. After a quarter of an hour, the laptop can be turned on again.

Attention! The considered problem can appear in any equipment, regardless of its age and manufacturer.

Why does the laptop work only from the network

In 99% of the past difficulties the drive is to blame. After all, any battery has its own approximate guaranteed period of use. If the device is physically outdated and the battery has not changed since the purchase, then you will have to buy another. The fact is that after a specific time, the cells lose their properties and it is already unrealistic to charge them. Failure can only be detected by a service technician using specific equipment. If the battery is brand new, then the following reasons are possible:

• Normal short circuit caused by poor battery. In this option, you need to get it and work on the device without it. Then the battery is inserted back and turned on only with it, not focusing on the network.
• Even brand new batteries can "sit down" in a short period of time. After all, everything will be determined by the assembly characteristics and the reliability of the equipment supplier.

Often there are situations when the user cannot understand the inconsistency, because the drive is connected and the display button indicates its charging. However, in reality it is not. In these circumstances, the methods already described should be applied. If they did not work, then the snag must be sought in the following:

• Defective charge or weak power due to wear of its components. If the gadget quickly loads without battery, then pay close attention to the power module or other links and micro connectors.
• Drive failure or controller malfunction.
• Faults due to connection and wiring. Often oxidation occurs.
• Damage to the connector on charging.

Important! In more difficult circumstances, flaws can be detected at the level of the nutrition structure of the gadget itself, and only experienced experts can diagnose them.

What to do?

Before taking various measures with your own hand, it should be clearly understood that the power module is inserted both in the device and in the power outlet. If the connection is through a surge protector, then you should make sure that it works. If the power supply consists of a pair of independent elements, then disconnect them, and then reassemble. Consider more specific subtleties that may come in handy:

• Often there are inconsistencies with the utilities after installing the updates, so it is recommended to download the original software to adjust the power supply. For example, in some advertised utilities, a mode is set that provides the maximum possible battery life. That it can be a blocker of the charge. Ultra-modern systems are able to independently determine the best procedure for using the drive. Therefore, it is more correct not to download dubious programs.
• The charging tip pops up even if you disconnect the PC from the network with a fully charged drive and reconnect after a short period of time. The message will disappear soon.

Reference! It does not hurt to make sure that the rest of the household appliances (tape recorder, toaster, etc.) that are in the apartment or office are working.

If there are problems with charging the laptop, most of their owners prefer to immediately buy a brand new battery. After all, the warranty battery life is designed for 3-4 thousand times the charge and gradually the reserve is reduced. However, there is no guarantee that changing the element will solve this malfunction. You can establish the possible causes of malfunctions on your own, without calling the wizard.
