hello everyone. I have a Chuwi CoreBox 4th that won't boot up anymore. The fans are spinning and it turns on but nothing appears on the screen. I'm afraid it's screwed up the bios because before it crashed it was giving trouble getting into the various bios masks. Does anyone know how I can possibly reset it ? The bios is an "aptio."

Re: Chuwi CoreBox 4Th Bricked
Hello. After almost 10 days they sent me this bios. The problem that the pc does not read the usb stick when I turn it on. Does anyone have any idea how I can do ?
I could directly overwrite the bios with an external programmer ??
The bios seems to be 32 Mb.
Thanks

Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

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 soft BRICKED my Lenovo IdeaPad laptop (black screen with led lights on, responsive keyboard backlight, fans spinning) after messing about with a Github tool called Smokeless. I am now attempting to reflash the bios through USB, but I am not sure if I extracted the correct BIOS ROM file to flash, and I also could not find the correct file name to rename it to (GLCrisis.bin, GLCN.bin, Currom.bin??). In addition to attempting to reflash the Bios with a USB, I have also performed the following activities:
*Novo button power on
*Disconnected internal battery...
