Repl resistor ... no go.
I did short the green power supply wire to ground, and it boots. Maybe I'll just wire in a toggle and call it a day

DELL XPS 8500 - DH77M01 bios dump needed
As the title says ... I've seen it on some Chinese websites ... but my foreign language skills are for crap
Dell XPS 8500 / Vostro 470
DH77M01 CY0629
Dell part number 0NW73C
Board is currently getting power, but does not power on at all. Was going to try a bios if someone has a BIN dump of it. Should be 4MB I think.

Hi everyone,
I bought a used Dell OptiPlex 3090 Micro with a BIOS administrator password that I cannot remove. Dell support refuses to help without the original proof of purchase, and the seller is unreachable.
I would like to try flashing the BIOS chip with a CH341A programmer, but I need a clean SPI BIOS dump for this exact model.
Here are my machine details:
Service Tag: 50P1BB3
Express Service Code: 10925963391
Form factor: Micro
I can share my current BIOS dump (read with CH341A) for comparison if needed.... -

Subject: Request: HP Omen 17-cb107nr (LA-J672P) - BIOS and EC Firmware Needed
Device Information:
Brand/Model: HP Omen 17-cb107nr
Motherboard Model: GPC27 LA-J672P REV: 1.0

The laptop powers on, all voltages appear to be normal, and it seems to boot up, but there is no display (no output) on the screen.
The device was previously serviced at another shop. It looks like the BIOS chip was removed and reprogrammed before. I suspect the current BIOS dump on the chip is not original or is corrupted, causing... -
Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM
