My hp laptop wont turn on

This is a frequent problem am sure as you have already seen from online searches.

Flea power is usually the culprit here, basically its residual power that remains on the computer even after thecomputer has been shutdown. You can drain the flea power with the steps the other answers have suggested.

• Press the hardpress the power button for 30 seconds
• This should clear the flea power
