    Asus ZenBook 13 UX333F External Short - Fast Battery Drain - Need Help
    by jkucukov
    I'm trying to see if someone could help me with my Asus Zenbook 13 UX 333F with given symptoms that I've experience during a recent external short.

    During last laptop charge, as I was moving the DC power supply, I caused the two leads (+ -) to touch. After that event the laptop stopped charging and pulling amps form the power supply. The only way the laptop will come on is with the power supply connected and the battery having some charge to it, battery drains immediately after short operation (it gets to Windows log in screen before it shuts off). The laptop would power on, show...

    Weird behavior on 3.3V rail of a CORSAIR CX600
    by bimole
    Hi,

    A colleague gave me an apparently ill CORSAIR CX600.
    He told me that he heard a banging noise, and smelt the magic smoke.
    After tearing down the PSU, no burnt component, everything seems OK, but the PSU often refuses to stay ON. When shorting PS_ON to GND, the fan spins a bit a finally stops. No output voltages.

    I tried to treat some apparently bad solder joins and finally it seems to work OK... on the 12V and 5V rails!
    It's another story on the 3.3V rail...

    I have some devices to test deeply PSUs (scope, AC source, electronic load)...

    Lenovo 300e 2nd Gen Win version 81M9 DMI edit
    by AncientRocks78
    Hi,
    I'm owing a:
    Lenovo 300e 2nd Gen Windows Version
    Model : 81M9
    S/N : R911S76T
    MTM : 81M9S03300
    Board : BM5860_V1.3A​
    Since i had a password reset and did a corrupted Bios Dump, the laptop after flashing it, doesn't have the right S/N and so on.
    Is there a DMI Tool for this laptop so i can edit it manually, using the right system infos, and writing them to the bios file, any app, so i can do the things from the command prompt or a gui, please?
    I'll be very grateful, and thank you!

    HP 15-CS3131NB G7BD(2G) shorted cap
    by johnbeton
    Hello,

    I have this board in for repair, it came in not charging, not powering on. Found a short on a cap near the charger IC.
    With the cap removed, the laptop charges and works, but seems to work very slow.
    I have a second board with the exact same problem, and the exact same capacitor shorted. So I replaced the bad capacitor with the good second capacitor of the other board, and the laptop works fine now.
    I'm trying to identify which type capacitor this is, so I can order new ones to fix the 2nd board too, and maybe some future incoming since this seems to be...

    Changing ME Region after replacing CPU with another one.
    by Robin21
    Hallo,

    I've replaced Intel CPU SRKH5 with burned PCH on the LA-L051P with SRKH4 (i7-11370H to i7-11375H) and now I see that this was the easy part.


    Now I need to replace ME Region using this from the donor board - 15.0.47.2473 and need help from smarter people than me.

    Samsung UN50F6350 display turns white intermittent
    by Pwtzz
    TV runs normally but after 10-15 mins of watching. The TV gets less than a second of white screen (see 5 sec video) then it continues normally, just for it to do again after about 10-20 seconds over and over. If the menu is out it does it to the menu as well.

    I check the boards for bulging capacitors but there's none, I reseated the cables as well.

    Help is greatly appreciated.
