Re: DELL XPS 9550 bios dumps

I have dumps from a working laptop.

Those two chips are for thunderbolt FW and for power delivery FW,
i've compared them with multiple dumps, the content is always the same.

Re: DELL XPS 9550 bios dumps

Hello,
I am facing a similar, probably worst, issue with a XPS 15 9550 that is almost dead :
- first push on power button = lights on
- second push = nothing, no fan spin, no screen back-light.
- power led goes off after 10 sec
- LCD auto-test (d+power) never fires
- battery side indicator lights up, but i suspect it always display full battery, although that may be wrong.
- Battery charging led lights up when connected to PSU.

I tried to flash the main bios with the bin that you guys had success with, but with no luck. I also flashed the to other W25Q chips with bins i got from a working identical model. No better.

Its probably worthless, but i want to give it a final try using three bins extracted from a model that was saved by flashing the clean_me rom provided here. I dont't now, maybe those i have don't match and fail when calling each other on incorrect physical addresses.

Can anyone who successfully flashed the main clean_ME be kind enough to dump the bin of the two other W25Q and deposit them here?

Thanks in advance

Re: DELL XPS 9550 bios dumps

I have tried this image but i have a problem.. the laptop posts with the cleared ME BIOS, but only once, i can enter bios and it stay there working just fine, but after reboot it's back to black screen no post.

Any one have an idea what i could do?

Re: DELL XPS 9550 bios dumps

Worked like a charm. Thank you for sharing.

I had to switch back to UEFI in the settings to boot Windows.

Just FYI so you won't go around and desolder all 3 bioses to figure out which 0ne it is.

It is the one closest to the PCH - W25Q128BV
