SEi8 8279U don't boot : screen black

steph51

Hello
I modified the bios of my machine by modifying the boot on legacy.
Unfortunately, I have disabled secure boot.
the purpose of my maneuver was to boot from usb.
Since then, I have nothing on the screen, just the led on.
So I can't access the bios menu or the boot menu.
I tried to reset the CMOS, then disconnect the battery, without success.
Do you have a solution for me to help me out?
Thanks for your help.
Steph

Hello there,
Sorry for the trouble.
Could you please send us a picture of SN on the bottom of the PC and a picture of purchase record ?

Please take out the CMOS battery for about several hours and then try it again.

Please also take out the SSD and the RAM.  Clean the contacts of the RAM with a rubber.
