[danito]

Hello, I received this laptop because the client turned off while updating the Bios, I put a Bios from the forum but now it turns on when it wants, sometimes it gives an image and other times only the button light and no image, I attached a Bios backup.

Hi,

Can anyone help with this issue. The laptop powers up and spins the fans at fluctuated RPM. But no post or display. I have attached the original BIOS bin and the Serial number. Can some one help?

Serial : PF45EA11
Mode: Legion 5 15ACH6H

I have done reflash with above two files but no display.

Thank you

Computer charges and turns on
Upon booting keyboard lights come on and fan kicks in
Num lock escape and caps lock come on
No display on screen or via hdmi
I can hear it's loaded in windows but can't see anything on screen
I know screen works
I think I need bios as I've tried many other things
Thanks
