Here's your New BIOS, it's a Virgin BIOS from HP with your DMI and Windows Key.

Re: Need bios LA-E811P

Hey, thank you very much for your very fast help! I flashed the binary into the chip and the laptop is still locked into a bootloop as before flashing. All the voltages are ok, the problem came up after windows 11 update. There is no backlight problem. The laptop is in a bootloop. Thank you!

Bootloop without showing any image on the screen? Do you remember the BIOS Version before Update?

Re: Need bios LA-E811P

Hi! Thank you for coming back!
The screen is black, ON led is coming on, after a while the HDD is coming on (on but not active), no signal on HDMI, Win+B combination does not recover the bios (but the LED on the USB memory blinks for a second), I replaced the ram - no result, reset the bios (short on battery pins) - no result. All voltages are present 3.3V, 5V, 0.8V, 0.7V and 1.3V.
Thanks again for your help!

Have you checked for any missing components around the BIOS Chip? Have you tried to change the BIOS Chip itself? If you remember what was the BIOS Version before update, we can try it before assuming a Hardware Issue.

Hi!
The BIOS Version before the update wasn't important for me and I didn't take any pictures (I did not see this coming >>> REMINDER! <<<).

A few minutes ago I desoldered the chip and reprogrammed it (Neo) "success". Verified it "success". Resoldered it (https://i.postimg.cc/7xgTCs27/IMG-20230405-180029.jpg). I like to use this kind of soldering iron tip for these chips (https://i.postimg.cc/zv9XLYNV/IMG-20230405-181521.jpg) for less heat transfered to the board and less flying objects around me when the air is set too high ). This laptop ruined my Christmass. Offfff! Bootloop period is approximate one minute 20 seconds.

Re: Need bios LA-E811P

A friend helped me with a replacement motherboard. The laptop is working now. I kept the damaged motherboard for further work if new ideas arise.

Thank you very much for your help!

Forget about the DMI for now, it's a Virgin BIOS and it has the same BID (0832D).
Does it gives you the same symptoms (2,2 Blinking)?
