Laptop battery recently died, and I'm planning a new PC build anyway, so I'm wondering: can I just remove the HDD from my laptop and connect it to the motherboard? Would I need any extra parts or hardware? I'm guessing no, but it's hard to research on my phone. Any guidance is appreciated :) thanks!
If you were really lazy, you could also just cover the bottom circuit board of the drive with some electrical tape and just balance it on the jungle of wires running throughout the case.
Not that I would have any experience doing that...
You don't even need to do that. Unless you're pressing and rubbing the board against the chassis, any minor air gap and natural oxidation layer on each side is going to be more than enough for what's probably only 5 V tops.
