Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
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

Hi there! I have not so usual situation...
I have 2015 MacBook Air A1466 EMC 2925 with 8Gb of RAM. It seams that I've killed it by bad SSD adapter. It starts, cooler works... But no chime, screen is black. SMC reset seams works, NVRAM reset doesnt works...
My repair guy has checked all possible. It's all ok with power. The last idea - I could kill EFI firmware... So, I need a firmware of EFI to check it. I have a programmer. But I don't have a similar laptop now to download it and compare
P.S. If you have else any ideas about repair, or you had a similar...12-20-2024, 02:31 PM
