Hi all,
the patient of this week is a Dell XPS 13 (9370) with an i5-8250U in good cosmetic condition but with multiple problems. I'm trying to figure out whether it's worth investing more time or not. Here is the diagnosis:
- device powers up, during POST a missing TPM module is reported
- no boot medium found, not even listed in the UEFI (known good NVMe SSD)
- detects and boots a USB drive only from one of the USB ports (the one on the right)
- boots normally into Windows, performs well
- does not detect the WIFI module, the camera, the card reader and the finger print sensor (see the attached picture)
- SATA and TB3 are unknown, since I have no hardware to test with
- device manager shows only one PCIe port
To me it looks like a problem in the SoC. Or maybe a faulty power rail? I have the schematics but cannot find a candidate for a common source of the problem. Already tried a few different FW versions with no change.
Do you guys have experience with cases like this?
Cheers
