For laptop and netbook users, a problem periodically arises - the laptop does not charge. This happens for several reasons, each of which requires careful study. Only after this can we begin to solve the problem, because without knowing what it is, it is difficult to fix something.
No mains voltage
Perhaps the simplest reason why the laptop does not charge is the lack of current in the outlet. You can check this in the most ordinary way - turn on another device. For example, a mobile phone for charging. If nothing happened, then there is no voltage in the network. Why could this be? The mass of options, all are individual. For example, the old wiring and the powerful tool included in the neighbors. Or a power surge due to large-scale work with the electrical network in a house or area.
Power supply and its malfunctions
It happens that a computer connected to a working outlet still does not receive a charge on the battery. Most of the problems in this case are due to the power supply. First of all, inspect it. If the indicator light is off and the laptop is not charging, it is possible that the wire is broken. This most often happens due to improper twisting and folding of the power supply and its elements. To reliably verify that the broken wire is to blame, simply twist the plug in the charging socket. If the light on the unit lights up in a certain position of the cord, and then goes out, then it is still broken. This cannot be fixed on your own; a new charger is required.
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 loose, or the device itself has become unusable. This happens most often due to the fact that the computer is constantly connected to the network. Or the wire is simply not removed from the outlet. 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 stopped charging due to a failure in the settings. No way it can not be noticed. Unless the battery icon has disappeared on the control panel, you don’t see if the charge is on, how many percent are left and other nuances about the power supply. To find out for sure what the reason is in the BIOS settings or in the drivers, you need to install any program to your taste that checks the drivers for updates. If, after updating all the utilities, charging did not appear, then most likely the problem is in BIOS. What to do in this case? Direct road to go to the master. Self-tuning the BIOS in inept hands can lead to a reset in general of all settings and a slow "death" of the laptop. In agony and torment. There are viruses that attack just the same BIOS, but as a result of their “work” the laptop usually stops working at all.
What to do, the laptop does not charge, 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 can fix it. Self-repair does not always give a positive result, and in some cases, on the contrary, it finally completes the device.
