Hello,

Try this 1

1) Unplug the power cord --> Remove the battery --> Hold the power button for

60 seconds --> Connect the power supply then try to switch ON the laptop and

later put the battery back into the laptop.

2) If the problem still exists then click on the below link and follow the instructions
