Hello.
I came to a very weird situation with a T470.
Laptop worked great but locked, backed up the BIOS, successfully verified it, patched it with Autopatcher, boot successfully and completed the DXE procedure, flashed back the old unpatched bios and now only the green led of power button turns on and nothing else.
Tried CMOS reset but no luck. No physical damage around BIOS chip, i was very careful and checked MB on microscope.
Any ideas?
Both bios attached

Dear Friends., working on a Lenovo T470. All required voltages are present & the require Amps (.95mili amps), Also goes through the start process, turns off & then turns on but no display or any beeps. I think the BIOS Bin files are corrupted & has to be re-build. Can some pls. re-build the Bin File, Original Bin uploaded. Thanks in advance.

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, I was flashing the bios but now the machine does not come, the battery indicator turns orange when charge is plugged in. As soon as it plugged by charger or battery the power button and escape blinks once then fade out Sometime it blinks 3 timess .

I had read the chip next to the cmos battery (25q80jvsiq) then i realize that it wasn't the bios. as the bios is next the memory slot. By doing that could...04-17-2024, 09:27 AM -
Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder...
