    Dell XPS 13 9310 - Repair

    Hi,
    i have an DELL XPS 13 9310 to repair.

    It's mainly a Gen 11th I7 with 32GB of RAM.
    The error is that it flashes 2x amber and 4x white, which indicates a RAM Error according to dell.
    I had a dell logo and wasn't able to access BIOS menu.
    I measured the the surroundings of the RAM and used a thermal camera to see anything abnormal. I couldn't find an issue.
    So I decided to re-flash the BIOS, because it has no BIOS battery and the use case of the laptop, i wanted to eliminate a kind of corrupt BIOS.

    I desoldered the BIOS chip and made a few backups and made md5sum cross-comparision.
    I made a BIOS request here: https://www.badcaps.net/forum/troubl...30#post3482330

    hoaca388 kindly provided a BIOS Image. During the soldering, i killed accidently the chip, I removed it again and wanted to check its content, but the chip doesn't respond to ID checks.

    The BIOS Chip is/was a XMC25QH256B

    The problem is that these chips are hard to source. Is it possible to replace the chip with a Winbond W25Q256FVEx / W25Q256JV Type?
    I am happy with each comment.

    Thank you in advance.

    Best regards, Diego

      ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
      by DynaxSC
      Hi

      I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
      The SPI chip is an Winbond 25Q256JWEQ model (1V8).
      The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
      The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

      I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

      Dell G3 3579 BIOS chip ID
      by ezenia
      Hello,

      I bought a Dell G3 3579 eBay. The fault was not mentioned and it did not come with charger. Before trying to power off battery, I did some basic checks on the coils (in resistance mode) to see if there was any short. None were reading short. 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...

      Asus Chromebox CN62 - wrong chip put on BIOS reader
      by BMCappelletti
      Long story short:
      - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
      - gave the computer to his son a couple years later
      - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
      - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
      (seems like the story was not that short)

      He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
