Hi,

I have an acer aspire 4520 laptop. Some days before, i was searching in the internet like always and suddenly the screen blacked out. Since then i have tried to open it so many times. Although the power button lits up, the laptop would not turn on. This is the first time that it does like this.

Try this

1. Remove the battery and cable.

2. Press and hold the power button for 58 seconds.

3. Replug and start.

Good luck
