Sorry for double message.

After some time it seems to be fine, turns on and works perfectly.
after some more time does it again.

Sorry for late response, i was sick.
Turns on, works for longer, still stutdonws itself.
BTW Lan port is not working.

P.S. Maybe this is version issue? Becouse EC and BIOS versions are different?

Re: Lenovo L340 rebuild bios

P.S.S. after flashing new bios and ME firmware (From Lenovo web) still doesn't work, i think it is hardware issue. Situation : Completely disassembled, when i put board on table does same thing, but when i put board vertically, computer works fine

EDIT : hardware issue, fixed. Computer working.

Re: Lenovo L340 rebuild bios

Hello Lukosiukas
I have a similar problem. After I launched Bluestacks (an android emulator) it gave an error about hyperthreading and shorttime later i had a bluescreen. then i got into bios and changed some settings (nothing i remember that is excessive, netherless laptop bioses dont have many settings that may brick your device). after i saved settings it went off and did not start, no picture or backlight etc. because i am a mobile software developer and was working on an app i had no time to give it to lenovo shop. i brought the device to a repair shop and when i got it back my bios it had no serial info like yours. I have my all packaging and serial numbers etc. after restoration of bios my lan and audio does not work. if you manage to repair/restore original working condition would you inform me? thank you
