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

Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).

Hello first post!
Ok so after an (ASUSTek) optional Windows update, my old ASUS E403NA laptop rebooted and froze in the BIOS menu screen and was unresponsive so after about 30 mins I powered off and back on again. Now i just get a power LED and a black screen, I have tried all the basic suggestions and all the suggestions on the ASUS site, spoke to ASUS support who said I will need to pay for an RMA.
The laptop is worth €50 so I won't be doing the RMA at god knows what price.
So I have seen some videos where people have reprogrammed the BIOS...03-07-2024, 08:31 AM -
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...
