My laptop is 20 months old and has worked flawlessly until 2 weeks ago (this behavior started all of sudden).
In 90% of the times I try to boot my E531 it justs shows a black screen, even not possible to enter BIOS.
Then I have to press and hold down the power switch and then retry to boot.
After a couple of retries the laptop boots as normal and functions flawlessly.
Hardware diagnostics did not find any issues.
I tried to update the BIOS (v1.15 to v1.29) using windows tool and bootable CD-rom but without success (Update using tool does not work because after the restart the laptop is not booting, CD update gives an error that the necessary files are not on the CD).
I already removed the battery, pressed power button for 30 seconds and then reboot, but without success.
All help is appreciated.
