    How do you trim a BIOS file?
    by survivalbloke
    I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.

    HP X2 1012 G2 Type-C problem
    by pc boy
    Hi everyone. An HP X2 1012 G2 came the other day. The problem was that the device drained the battery while off. I checked and saw the current is 0.2 before start. I went and checked parts on the MB and saw that the JHL6340 IC that is responsible for controlling Type-C gets hot. Everything worked fine and I checked charging and data of type-C both were OK. I went ahead and replaced the JHL6340. Now it does not get hot, no current before start, charging is OK, but the data of type-c is lost. I mean any type-c device like flash memory or hdmi adapter etc. do not work. I tried another jhl6340 and...

    by the Benninger
    HI Folks, I have a problem randomly a BSOD screen appears in the event viewer indicates KernelPower failure, discard the source/memory and SSD, only the battery is in bad condition, it will be possible that the battery is causing this BSOD event , I mention it because the times he gave BSOD he happened to have the battery installed, and last Friday it ran all day without the battery installed and didn't generate any events
    At the moment I am checking the mosfets and voltges in general everything seems to be perfect on the main board

    Microsoft Surface Pro 4 (1724) SEMM remove from BIOS/UEFI dump
    by GeryMix
    Hello everyone!
    I have a surface pro 4 (1724) with corporate management set up (in this case, I understand it's called SEMM). In the operating system installer (Pro version), after connecting to Wi-Fi, it asks me to enter the company system. If I don't sign in, it won't let me continue (similar to enterprise enrollment on chromebooks). This can be avoided if I install the Home version instead of Pro, and then upgrade to the pro version, but this is not very elegant. I would like the machine to be as it should be in factory condition. That's why I would like someone to remove this restriction...
