Blacked out screen for Y400

For some reasons when I turn on my laptop my screen doesn't show it's just black!

I was using it just before going to work it was fine but then when I came home after work I turn it on and the screen stayed black!

Re: Blacked out screen for Y400

hi MaimeeVang,


Welcome to Lenovo Community Forums!


Booting up with a black/blank screen is pretty much complex,


Do you even have Power light or any blinking light when you press the power?


Can you Try to do a Power Drain

                >Turn Off your computer /  Remove your battery and AC adapter

                > Hold down the power Button for at least 10 Seconds (that should drain it out)

                > Reconnect the AC Adapter only (Leave the battery out) then try to turn t on.

See if that helps,


:Can you share what shows on the screen when you turn it on or is it just a black screen right away?
