If the laptop does not charge ... What is the reason?

Users of laptops and netbooks periodically have a problem - the laptop does not charge. It happens for several reasons, each of which requires careful study. Only after this, you can begin to solve the problem, because without knowing what's wrong, it's difficult to fix something.

No mains voltage

Perhaps the simplest reason why a laptop does not charge is the lack of current in the outlet. It can be checked in the most ordinary way - to switch on another device. For example, a mobile phone to charge. If nothing happened, there is no voltage in the network. Why this can be? There are lots of options, all are individual. For example, the old wiring and included in the neighbors a powerful tool. Or a surge in voltage due to large-scale work with the electrical network in the house or area.

Power supply unit and its malfunctions

It happens that a computer connected to a working socket does not get a charge on the battery anyway. Most of the problems in this case are the power supply. First, look at it. If the indicator light does not light, and the laptop does not charge, it is possible that the wire is broken. This happens most often due to incorrect twisting and folding of the power supply unit and its elements. To reliably verify that the fault is the broken wire, simply twist the plug in the charging slot. If the light on the block lights up in a certain position of the cord, and then goes out, then it is still interrupted. You can not fix it yourself, you need a new charger.

If the light on the power supply is on, and the laptop is not charging, then the problem is in the power supply. It is possible that the wire coming from the power box does not work, the socket is loosened or the device itself is unusable. This happens most often because the computer is constantly on the network. Or the wire just does not get out of the socket. In this case, it is also recommended to purchase a new charger of the appropriate model or a universal charger.

Errors in the system and settings

Sometimes it happens that the laptop has stopped charging due to a failure in the settings. It is impossible to notice this outwardly. Unless the battery icon disappears on the control panel, you do not see if the charge is coming, how many percent there are and other nuances about the power supply. To know for sure what is the reason - in the BIOS settings or in the drivers, you need to install any program to your taste, which checks the drivers for updates. If after updating all the utilities charging did not begin to appear, then, most likely, the problem is in the BIOS. What to do in this case? Direct way to go to the master. Self-tuning the BIOS in inept hands can result in resetting all settings and slow "death" of the laptop. In agony and torment. There are viruses that attack just the same BIOS, but because of their "work", usually a laptop generally ceases to work.

What to do, does not charge the laptop, the knowledge is not enough to cope on your own? Go to the master! Only a specialist will tell you what happened to your computer and will be able to fix it. Self-repair does not always give a positive result, and in some cases, on the contrary, finally finishes the device.
