Re: W540 no boot blinking lights 2-1-2-1

forgot to mention... I did try removing battery and power cord and holding power button for 30 sec (1 min to be sure), and no changes in behaviour. also, the only way to stop the blinking is to remove both battery and power cord... 

 

Any ideas how i can get this to boot?

Is there any guide that explains the blinking patterns?

 

Thank you!

Andrei
