Hey everyone,
I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.

I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.

Decided to power the board to see if anything happened. The keyboard backlight came on. About 5 seconds later, the fans begin spinning at max speed. The white LED comes on at this time, stays solid for a bit and goes off. Fans continue to spin at max. Display is black (no backlight). If I hold down power button, board goes off. I did give... -

Hello,
Is there any known way to check Dell BIOS dumps integrity after downloading from the chip?
I ask this to make sure that I don't get a corrupted dump.
Thank you very much!
