    Windows 11 Start menu/Taskbar hanging
    by reformatt
    Couple of Windows 11 machines have come in this week with the same issue. After you login, the taskbar will not appear (or just be a black bar). No access to Start Menu. Task Manager (use CTL+SHIFT+ESC) works, however the Performance stats seem stuck with CPU on 100% for Task Manager itself. Trying to exit Task Manager result in it hanging as well. No issue if you boot into Safe Mode.

    First machine, tried many things to no avail (System Restore from last Windows update, rebooting in Diag mode, trying to reinstall Windows Apps via Powershell). In the end, I did an in-place upgrade...

    A1990 820-01041 5V .4A Troubleshoot
    by abajor
    I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
    so I swapped U3200.

    I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
    It's hard to judge the actual temperature without removing the shielding.

    Does anybody have any insights?

    220VAC locales... ever used DC to feed switch mode power supples...and how many volts is generally okay?
    by eccerr0r
    For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
    What kind of PSU?
    I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
    Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?

    Currently have a 120/220V switchable SMPS I want to see if I...

    Dell latitude 5320 corrupted bios repair
    by wwbielsko
    Hi,
    I got corrupted bios bin file, which way is correct to repair.
    File puts errors on Me Analyzer and cannot open in FIT.

    To open in FIT I made:
    1. Extract MFS and EFS using MEAnalyzer from other bios file with the same parameters
    2. put it in HxD to my file
    3. MEAnalyzer shows 1 error after that
    4. file opens in FIT

    and:

    A:
    1. extract current dell bios on website
    2. put System BIOS with BiosGuard v1.30.0.bin using FIT
    3. MEAnalyzer OK no errors
    (this version shows only logo at bootup - freezeing)...

    Hello guys,

    i got this laptop from a friend to solve a problem.
    The Laptop got a black screen. After turning it on, the keyboardlight is on and the fan working sometimes but nothing to see. The LCD is fine.
    I did the LCD selfttest.
    I think my friend tryed to update the Bios and failed.

    I have a TL866 ll Plus and ordered a SOIC8 clamp. I want to flash the Bios on circuit.
    I don't know which of the two chips are the bios.

    Near the CMOS Battery: MXIC MX25L8006E
    Near the CPU: AH1721 259(8)128CSIG E7A026 the 9 can be a 8.

    DELL XPS 9520 No 3rd party SSDs?
    by abajor
    So we have a DELL XPS 9520 a woman broke her screen and needed an immediate replacement so we removed bitlocker and put her Drive in an Asus TUF gaming laptop, everything is hunky dory.
    We happen to have another DELL XPS 9500 screen that is compatible with the 9520, so tried installing new SSD's and doing a clean windows 11 install.
    During formatting the installer can't find the Intel drivers for the nvme controller?

    I spend a long time figuring out how to extract the drivers from the official dell installer downloads tried different versions, was able to load the drivers...

    Lenovo legion y540 adapter pin id
    by TheOtherGuy
    So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...
