    MSI 7600 GT, shorted capacitors
    by FlameOnion
    I got this gpu that does not work, is not detected in windows(not shown as a pcie device),the heatsink got a little warm. MSI 7600 GT PCIE, NX7600GT-T2D256EZ.

    Tested in different motherboards, same issue. I got it with a capacitor broken(one leg was left), and an broken indictor related to fan pwm I think.
    As a hobby I tinkered with arduino, I got a soldering iron and a hot air gun, no experience in repairing(occasionally watched videos of northridgefix)

    I measured randomly capacitors for short and found some shorts on a few, and found short on a few mosfets....

    ASUS N550JK laptop reboots after 30 minute, BIOS extracted invalid...
    by bschwand
    Hi all,

    as subject line says, I have a laptop that reboots after 30 minutes. Investigation leads me to believe that is due to intel ME as it happens everytime after 30 minute from boot, it just turns off, no overheating, nothing weird.
    I found a lot of information about cleaning ME like this [URL]https://winraid.level1techs.com/t/guide-clean-dumped-intel-engine-cs-me-cs-txe-regions-with-data-initialization/31277[/URL] and this [URL]https://github.com/corna/me_cleaner[/URL]
    Anyway, first step is to dump the bios. I found the Winbond W25Q64FV chip on the motherboard, dumped...

    MSI Katana B12VFK keyboard backlight
    by Dobrowol
    Hi. I need to replace the keyboard in MSI Katana B12VFK. Unfortunately, there are no keyboards with a wide backlight flex available. However, they come with a narrow flex. Do you think that if I put a connector that the manufacturer did not install in this version, will the keyboard backlight work?​...

    A2442 820-02098 5v 0a
    by sewsulle
    Good afternoon,
    I'd appreciate help diagnosing my A2442 that's only taking 5v and 0a

    This was my personal laptop and I had closed it at the end of a class and opened it in the next class when it just didn't wake up from sleep (The battery was charged). I connected a charger later that night and it booted right up but touch ID stopped working. The next day it did the same thing but never turned back on when I plugged in a charger.

    I though the touch ID issue was weird but I'm not sure if that info helps.

    When this happened months ago I tried to diagnose...

    Macbook Pro 14 2021 - A2442 - 820-02098-A - Internal display not turning on but MacOS working good
    by modtool
    Dear collegues,
    the owner of this machine brought it to me saying that suddenly one day the display didn't turn on anymore, he tought that all the machine was damaged but it turned out that the MacOS starts good and stays on, and that connecting it to an external display it works without problems.
    If you take a look into general settings, you can also see that the internal retina display is recognized as connected by the main board but for an unknown reason it doesn't turn it on.
    I've tried to put a bright light towards the screen but I can't see anything, any shadows or apple...

    Dell precision 5520 It only starts with the battery disconnected and with the ac power not recognized message
    by Fabbrone
    [FONT=Aptos][FONT=inherit][COLOR=#202124]Already replaced adapter, battery and dock connector. If I only connect the adapter with the battery disconnected, it turns on with the message bios adapter not recognized. While if I connect both the battery and the adapter it doesn't turn on. When it turns on only with the adapter and I try to update the bios it tells me to connect the adapter! can being connected. If I connect the battery when it is turned on with the adapter it turns off. Do you have any ideas?[/COLOR][/FONT][/FONT]

    Samsung QE82Q70RAT no backlight
    by sansanpartida
    Hi everyone!

    Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.

    My issue: No backlight.

    Model: QE82Q70RAT
    Type No: QE82Q70RAT

    The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.

    So hopefully, I can fix this cheaper.
