I normally powered off my laptop , and then when i try power on again , just a blank screen.
Power light is on , no wireless light nor hdd light.

I seperated all parts and renewed thermal pastes, tried to short cmos battery , tried without hdd , rams nothing on site worked..

At first i wasnt able to flash bios from usb but when i tried flashing it while hdmi cable is in it worked , usb shown activity for 2min
Then it powered off and on itself , but still no screen.

What would i try else , cmos battery is not replaceable on this model , should i go see repairer to replace this battery?

    Does it seem to be booting up, but no screen?

    Did you shut down with HDMI connected to TV and then remove HDMI before booting up?

    No , not booting at all cant even access to the bios. Problem isnt about the screen there is no light on screen , no screen with external monitor too. Only power light is on , dvd drive spins a little bit , cpu fan spins2 sec , then nothing when i power up.

    (If you mean did i do that when it was working , it s highly possible i did that but i dont really remember its been 3month)

    My experience with computers that act as you describe is it has something wrong with the motherboard.

    Yes probably.do you think if i work it out by replacing cmos battery? If i go see service they probably will ask for 150$+ for motherboard that i cannot afford im afraidSmiley Sad

    You can try it, but I don't think the CMOS battery is the problem.Have you tried removing the power and battery and holding the power button down for 20 seconds, plug in power and try booting?

    Yes of course , i think i tried everything i found about problem in internet , all failed.

    Any possibility i put the wrong files to my usb when flashing ? Would it be completed anyway if i did put them wrong?
    (Flashing process completed 2times but didnt work)

    No, if you had a incompatable bios it wouldn't flash.
