    iMac A1311 - Motherboard 820-3126-A, turn on sometimes
    by ryogadan78
    Hi guys, I have this 2011 iMac A1311 with a strange problem.

    Most of the time, when I plug in the power cord, the first of the 4 LED's turn on, but when I press the power switch the LED turns off and iMac won't boot up.
    Sometimes, when I unplug and plug the power cord back in, iMac starts up correctly by turning on the 4 LEDs in sequence.

    I have already tried a new power supply, but the result does not change. Do you have any suggestions?

    Evaluating Mechanical Hard Drives SMART Data in Linux (Ubuntu) Using the Disks Utility.
    by abajor
    I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
    I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
    The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.

    Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

    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?

    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.
