Laptop power adapter is 20V output, but I measured with a universal meter, the output only 6V, can not boot, which heroes know which part of the adapter or which component, please help out, Xianxie had The
Check the large capacity of the electrolytic capacitor there is no drum top, leakage, if replaced, the rest of the fault requires a certain level of technical maintenance, to explain the long story, or take the maintenance department it.
This is not necessary to repair. Ha ha. Directly on the Taobao search force Yang technology mall to shoot a line on the line.
With a multimeter direct plug the terminal, the output is low adapter is broken, there is a general power supply control chip is good, should be divided voltage is broken.
Notebook Charger (Laptop Charger), also known as laptop power adapter. That is, the laptop's charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry called the traditional notebook power adapter for the single-band notebook charger (mainly in order to distinguish between the universal notebook charger.) Laptop power adapter work The principle is simple: that is, the use of unstable power supply switching power supply through the conversion circuit into the notebook computer needs constant voltage DC, to the laptop power supply and charging. It is worth noting that this conversion circuit, there must be protection circuit (overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.) to prevent accidents, the protection of the laptop will not burn.
