SEi8V3-G Blocked on Beelink screen without possibility to go in bios

Alex59

Hello,
Yesterday, aftera little a small ipdate on windows 11, the pc never reboot.
My SEi8V3-G is blocked on Beelink screen without possibility to go in bios.
I put a keyboard with usb port, i used all keys to be sure, but nothing.
How can i reflash the bios ? I think I need to put a new version of bios in usb et click on the CLR Cmos ?
Can you help me ? I can't find the bios to do this opération :/
Thanks

Hello there,

① Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. On Save&Exit page, please click Restore defaults, press enter to confirm, then press F4 to save.
②Please turn off the PC , unplug the power supply, and press the CMOS button (poke the hole of CMOS with a pin) for about 10 seconds , restart the PC after ten minutes.

① => no effect on key pressed

② turn off the PC , unplug the power supply, and press the CMOS button for about 10 seconds
wait ten minutes
plug the power supply
the pc start, black sceen, after 3,4 seconds, the pc restart => beelink logo with press key to go to Bios... (same  ① )

I presume "press the CMOS button" is to uncharge BIOS battery
to be sure with 10 minutes i waiting more long time, but the same
Le keyboard is ok and I can use ctlr alt del to rebbot the pc
I try to tap on all keys, but nothing
My PC is dead ?
