mb model DAG3PMB38A0
laptop model no:hp 15-fb0010nt
serial no:5CD2403PMB
The laptop starts but there is no image on the screen. I think the bios software is corrupted. If there is a working bios, can you share it?Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello everyone.
I have another HP OMEN 16-C0114NW laptop with serial number 5CD1501LJX. The original problem was as follows. The laptop could not load Windows and every time it threw a bluescreen - y - most often WHEA_UNCORRECTABLE_ERROR. The processor that was originally in it was AMD RYZEN 7 5800H MOBILE PROCESSOR - 100-000000295. I decided to replace it with a fully functional, used AMD RYZEN 5 5600H MOBILE PROCESSOR - 100-000000296, which I got from a donor board, on which it worked 100%. After soldering the processor, I also uploaded a new, fresh BIOS to it with the UBT2 program... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
