What are the reasons why the laptop can not be charged?

Laptops can't charge up is usually a power adapter and battery failure. Laptops are highly integrated power devices with high voltage and current requirements. If the input current or voltage is not within the rated range of the battery, it may damage some internal parts of the computer.

Notebook power adapter can withstand the input voltage is usually 100V ~ 240V AC, if the access voltage is not in this range, such as the voltage is too low, the transformer converts the input current is too small to meet the normal work of the computer, the voltage is too high, the adapter converts the voltage, its own heat is very large, if not with a heat sink or bad heat dissipation conditions may lead to internal circuitry can not work properly, or even damage the circuit, thus causing damage to some internal parts of the computer. Normal work, or even damage the circuit, resulting in no voltage output or output voltage instability failure. Or some people have damaged the original adapter, to buy a new charger cheap, only look at the price do not look at the quality, to buy a fake and shoddy products, 95% of these power adapters can not guarantee the safety of charging, and even on a period of time will soon be damaged, the natural computer can not charge the power.

Batteries cause the computer can not charge the reasons are: no voltage output of the battery, can not be charged, and so on. According to Eahunt power adapter manufacturers understand that the laptop battery cells have a certain number of charge and discharge, if more than the limited amount, the cell will be aging and damaged. Although the circuit board of the battery has a certain protective effect on charging and discharging, if used for a long time, or the battery is often overheated, the circuit board is prone to failure thus causing the battery to appear no voltage output or can not charge the fault.
