The HP notebook won't open, and there is no response when you press the power button. What's the problem? How much is the repair?

If there is no "any" reaction, it may be one of the following situations:

1, power failure

2. The power button is broken.

3. The motherboard is broken

The power supply is the most likely, so check the power supply first and try it with the battery and the power adapter respectively. If the same phenomenon still occurs, generally speaking, the switch or motherboard is broken and needs to be disassembled for inspection.

The battery price is around 200-400 yuan; The price of power adapter is around 30-60 yuan; The switch button is tens of dollars, and the motherboard is more expensive. If it is replaced, it should be above 600 yuan. If the motherboard is repaired, the price depends on the situation. There is also a maintenance fee of 30- 100 yuan.
