Have a couple Compal LA-8241p boards. One has no internal video but starts just fine. The other board starts but then quits after about 5 seconds. Which chip do I remove to put into my programmer and lift the bios file from from? UH2 or UH6? Page 13

Hi, everyone!
I've recently acquired two brand new SPI chips to replace the one currently in my Acer A514-54G laptop MB (FH5AT LA-K092P). The reason why I'm replacing the current SPI chip is because I had some difficulties with a third-party IT assistant who pretty much lacked the soldering skills and ended up destroying the current SPI chip soldered to my MB from factory.
I've decided to do this on my own because I spent the past month or so learning some soldering skills and BIOS modding through Badcaps and WinRaid forums, hence the attempt. I've also chosen to buy... -
Hi all I hope im doing this correctly,
I need a firmware dump for the Nuvoton NCT6687D‑M controller (EC flash chip: W25X20CLNIG) used on the MSI B660M Mortar DDR4 (MS‑7D42, revision 1.1).
I acquired a ch341a black to reflash my bios, and was so excited to use it that I tested it on the W25X20CLNIG 3.3v chip as I didn't have the 1.8v yet for the bios chip itself.
Being a total newbie I straight up corrupted the EC flash chip, and now the power button does nothing, PS_ON# does not change, and when I manually short the PS_ON# pin it immediately turns off... -
Hi there,
First, I'm not sure it's the right section to post for this type of device, but could not think of something better.
Ok, so my son (a mechanic) bought a faulty Hofmann Geodyna 6300 wheel balancer (which appears to be mostly a re-branded Snap-on wheel balancer).
I'm looking for any resources (doc, manuals, schematics) that would be available for this device or anyone that would have any knowledge on this particular device (or its Snap-On equivalent).
I'm trying to diagnose the fault(s ?), but I can't find any schematic (appart from the... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
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...
