  • Does the power supply turn off, entering short circuit protection, when plugged into the laptop? If so some capacitors on the supply line may be shorted. Usually they are all in parallel so to find which one is shorted go by trial and error: remove each shorted cap test continuity outside the mobo. If it beeps it’s dead. You should be able to power the laptop without that cap.

    Note that caps under/behind the CPU/GPU appear shorted even if they are working when the laptop is off, do not touch them


  • Also if you’re considering new hardware already I really recommend looking into surplus enterprise gear. I run my whole lab on an R730XD. It holds a ton of drives, has an IDRAC (I can’t live without it now), ECC for extra peace of mind during ZFS scrubs, and they hold an insane amount of inexpensive RAM. They’re fairly cheap on eBay or from refurbishment companies. Bring your own drives with warranties though, used drives are a headache. Servers like this can be really noisy though, I keep mine in the basement.

    I’ve briefly considered it but it is out of the question for me. Not enough space in the house and enterprise gear is way too noisy. This setup will probably sit next to the TV in the living room so it has to be as silent as possible.
