Re: acer one d270 dead
Specs are very similar so it should be OK.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView

Re: acer one d270 dead
Probably short to ground after the MOSFET, ie. on the VIN line: main power rail of the machine. Inject voltage on VIN (start with 1V) and check what gets hot.Last edited by piernov; 07-26-2017, 07:36 PM.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView
