    GB RTX2080 Super - crash on load > second switched 12V instability > what is purpose of this circuit?

    Hello.
    Have this GB 2080 Super that crash on load. When half load i see instability on one of two switched 12V rails. I dont know its purpose and dont have BV or Schema for this board.

    Can anybody explain me what is purpose of this two switched 12V lines?

              Satellite r945-p440 - Hard crash coming out of sleep
              by cappernicus
              Toshiba Satellite r945-p440
              Motherboard: FAM2SY2 A3256A
              I do not have a schematic or board file

              I usually let it go to sleep every time I use it because it is nearly always plugged in, with occasional shutdowns to reset things. Then it started to hard crash every time it tried to come out of sleep. The lights would come on for half a second but before anything shows on the screen they would all shut off and it would boot up as if I had shut it down completely (except that windows knows it didn't), and when it comes back on the fan ramps up to full and stays there perpetually...

              MOSFET PURPOSE
              by irfan karatela
              I'm looking at the PS5 motherboard, and have come across 2 mosfets, I want to understand the purpose of the 2nd mosfet as the source is connected to GND and the drain is connected to 5v. wouldn't this short the 5v rail once the 2nd mosfets gate is enabled?

              Thanks...

              6800XT artifact on benchmark and crash
              by HelpMeRepair
              Hi guys , thanks for the help and hint in advance

              I have a 6800XT that is detected , but im not able to memtest it ( says it cant buffer )

              if i try to benchmark it , it goes artifact and crash after few seconds.

              anyone have a clue ? thanks !

              card is a AMD FE 6800XT , and any hardware mem guide checkup can help if you have any tuto too !😀

              edit : component looks good after visual inspection .

              ThinkPad T14s Gen 1 boot loop (instability)
              by mrfree2ita
              Hi all, I'm looking at what seems to be a nice puzzle

              A ThinkPad T14s Gen 1 that stopped working more or less a month after the warranty expired. I tried to boot both Windows 10 and Debian 12 from a USB stick. In the first case, the system just reboots after showing the Windows logo for a few seconds, while I'm able to see the Linux kernel crashing if I boot the second in failsafe mode.

              Interestingly, some times (unfortunately it's difficult to replicate) I manage to boot into Debian 12 live. Moreover, the kernel doesn't seem to crash always at the same point during...

              EDM 033 caps I'd and purpose
              by James Boden
              Hey guys just wondering as to the purpose of these caps 560 but they seem to be shorted .. is it linked with the super low impedance of the CPU/GPU or do I have a short to search for ??.. the short is still there when caps have been removed.. sorry still learning really 😞.
