    Liteon PS-6301-08A - Quick question

    Hi, Hoping that you're all enjoying the orchestrated panic demic
    Just got around to replacing some bad caps on this PSU, and noticed that one non-output electrolytic on the secondary side has the positive connected directly to ground.
    Is this normal?

      negative voltage rail?

          It is for the -12 volts, should connect to pin 12 of the atx plug

              Yep,
              Thanks for the confirmation - i'm guessing that that is because the -12v works of opposite side of the sine wave, and therefore ground is postive in comparison (or something like that)
              Just recently discovered it by looking at some other liteon schematics
              Finally got around to replacing the bad caps after several years
              Managed to lift 2 solder pads in the process and scratched a trace (the floor isn't an ideal place to work) - fixed with superglue
              Two of the bulged caps were so bad that they didn't even give a reading on the transistor tester - one of them was between the small transformer and the heat sink, and i've forgotten where the other one was.
              Works well now, and very quiet fan.

                  Macbook Pro 16" A2141 screen artefacts, kernel panic
                  by sofles
                  Hi there.

                  I have Macbook Pro 16" 2019, model number A2141, motherboard number 820-01700. I have some problem with dedicated graphic card. When Macbook switches to dedicated GPU it is getting instantly hot and starts to show glitches on screen, then it freezes (trackpad is not clicking anymore) and shuts down.
                  I tried to reinstall MacOS But it was a pain, it started to show glitches in middle of installation and I could not finish it. I only was able to reinstall MacOS when I put Macbook outside (it is winter and -2 Celcius).

                  Now situation looks like this, If...

                  MacBook Pro A2141 - macOS Kernel Panic
                  by prw07
                  Mac crashes and restarts with kernel panic. No water damage on board. Board is clean. Memtest86 showing no errors. The installation Ventura or Sonoma is successful, but after 5-10 minutes of operation, the accident occurs again. Did a DFU restore and revive, twice with success and successfully reinstalled Sonoma. After 5 minutes of work Mac crashes with Kernel Panic. Apple Diagnostic (AHT) does not find errors.
                  How to localize the problem ?

                  A1990 Constant Kernel Panic: AMDFramebufferVIB::setPowerState
                  by ronaldopdias
                  Hi, I have an A1990, i9 & Radeon 560X. Before it was freezing every few seconds, almost as if failing SSD, even on external macOS installation. I have tried a clean reinstall, revive + restore T2 firmware and it now works fine, other than it seems to kernel panic after some time in sleep.

                  Below is the kernel panic log, its similar to a lot of posts online for the same model, with no comments on how to fix the issue, and whether its firmware related or an LB issue. Most seemed to happen running Catalina but I am on the latest version of macOS Ventura....

                  Lenovo T470P NM-B071P not charging, 20 volts on positive +ve battery terminal
                  by Zibbo
                  Lenovo T470P NM-B071P had no power. PQ2 and PQ11 were shorted, repaced them and laptop turned ON. Connected the battery and the motherboard turned off immediately and it won't charge, checked the voltages and found out that there is 20v on the positive battery terminal.
                  Replaced battery charger IC PU101 and the two switching mosfets PQ101 and PQ102 and still same problem. Now I can't figure out how 20v is ending up on the battery terminals.

                  Dell XPS One 2720 AIO Liteon PS-3261-9DA not starting up immediately
                  by cheeky2
                  I suspect the issue is with the power supply Liteon PS-3261-9DA as apparently they are notorious for issues with them. Has anyone else had similar issues where the PC tries to boot up a few times before finally booting up. Now I have opened up the PSU which shows no signs of any capacitors failing. I did remove one capacitor that looked to have an issue however with my peak meter it showed it was within the limits with good very low esr values which was somewhat disappointing!
                  I am going to put a Meter leads across the outputs to see how stable they are when it occurs to see what they are...
