    Thinkpad E14 Gen 2 NM-C771 - No display no fan no beep no boot
    by ongobongo
    Hi there,
    I got this laptop which was not working at all. When attached to an amp-meter, the meter wasn't working at all also. I quickly found out that the PD-Power switch was gone and fully shorting to ground. After replacing that (NX20P5090) I got live back into the laptop.
    Now the battery is charging, charge indicator is working and the power led is blinking 3 times when i attach a charger. but, unfortunately, this is it. When i push the power-button, the power led turns on, but that's it. No display, no beep, no fan spin, nothing (but cpu gets warm).
    I tried flashing a new...

    Dell Inspiron 14-5448 - fan turns off and mobo keeps running
    by Felipe_Serra_83
    Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.

    So I got this Dell Inspiron to play with.

    No charger, so I connected to my bench PSU.

    The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).


    ------What it did (and didn't do)------

    1) I turned it on and it powered on. Powered down in 2 seconds by itself.

    2) Removed RAM, changed slot. Same...

    by prototypedoc
    Hello guys,

    Got my hands on this laptop and started troubleshooting. The only thing I know is it turned off and never came on. No lights and not coming on.

    Started doing some checks and found the main rail present everywhere. Something weird though as the gate of the first input mosfet is 3.7V and the output is 20.3V.
    Tried to trace the gate and it looks like it's connected to pin 61 on the io. Is the IO supposed to monitor the gate voltage?

    5V and 3.3V are missing from the coils. Found by lifting PL6202(on the 5V rail) the clicking fet sound goes...

    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?

    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...
