    I recently got ahold of a bright green Chieftec/Chenming "Dragon" case (I've always liked these cases, especially in "oddball" colors) and decoded to throw together a period correct-ish build.

    Lenovo laptop display isn’t working
    by Fribbs
    Hello,

    I’ve inherited a laptop from my brother as he’s bought another.

    However, the screen isn’t displaying correctly. See the image for the full picture.

    He mentioned that it wasn’t instant - it progressively got worse over time, and it used to sometimes work by tilting the laptop. Although, it looks completely broken now.

    It’s worth noting that the laptop screen seems a little loose.

    Any help/guidance would be appreciated.

    Thanks,
    Sam...

    ATX PSU Cooler Master RS-700-pcaa-e3 shutting off after 5 seconds
    by dariolana
    Got this from my kid with a fault on primary side. Main power supply here is AC 220V. All caps were Ok, testing with 2 series lamp of 70W each, got a bright lamp . Checked main heatsink one by one with my component tester and found one 3 leg buddy MDP18N50 that passed away. Got same replacement after a week, tested, short was gone, now I got 310V on primary.

    Happy as a dog, added one case fan for some load and the fan of the PSU. Tested purple wire, got 5.1V, great!. Shorted green and black, fan spins and after about 5 seconds shuts down. I was able to measure doing several iterations...

    Why doesn't any manufacturer create a multimeter that measures current in the same way as voltage?
    by cap__
    "Current is measured by inserting a measuring device into the circuit to measure the flowing current. Voltage is typically measured in a circuit in parallel. Why isn't the current calculated from the voltage?"

    SAMSUNG UE58MU6122 dump file needed
    by unimatrix93
    Dear Community,

    I have a Samsung UE58MU6122 with no power LED.

    I checked the PSU, all output voltages are present so it's probably good.

    Doing some research I found that the corruption of the SPI memory chip can cause this problem and the TV started acting like this after a power outage.

    Can somebody please provide a dump file so I can flash it to the IC?

    Thank you!😊
