Laptop boots and switches off under 15 seconds


Dear Forum Members,


My lenovo laptop switches on and in under 15 seconds goes off again. 

While I press the power switch a second time, it starts, does not go off this time, but nothing comes up on the screen.

I pressed the CD rom button but the drive does not come out either. 

Connect a phone to the USB port, it seems to charge. 


Removed the RAM and placed it back, removed the fan, cleaned it and put it back, but nothing helps.


Request you to let me know the possible cause of this issue.


Appreciate your help.

Re: Laptop boots and switches off under 15 seconds

Welcome to the forums Nayan!


Reset the BIOS to default before you do anything else. 

  1. Unplug AC adapter (remove from notebook).
  2. Remove main battery
  3. Press and hold the power button for 30 seconds (power drain)
  4. Replace main battery
  5. Replace AC adapter


Please provide the system model number for better assistance.


Let us know how you get on.
