    Could be a bios or motherboard fault. If a rail dosnt come up some systems will turn off after some time. If you have a bios programmer you can try finding a bios dump and see what happens. Hell it could be a bad power brick and a faulty battery. Think i have even had a system do that whith no ram in it.

      Dell G3 17 3779 Weird power cycling and shutdown/restart issue
      by SuperJames
      This one's a weird one, and still unsolved despite it having gone back to Dell once.

      Specs

      i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.

      Backstory

      I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...

      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
      by rounin
      Hi everyone,

      I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

      🛠 Original Issue
      The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
      Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

      I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
      by ugamazing
      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

      by shahnld
      Good day Experts
      I have a lenovo Legion pro 5 16ACH6H with AMD RYZEN 7 5800H and RTX3070,.

      A weird issue has troubled me. If i power on off the laptop 20 times then only power LED will lit but no fan spin no display. At this stage gpu, vram. DDR voltage. 5v 3.3v 1.8v and the rest are present and cpu core is stuck at 0.84v.

      And sometimes lets say the 21st time it will boot perfectly and there is image and everything is working perfectly and at this stage i see cpu core...
