Re: acer aspire one kav10 no power

17v+ is normal upon plugging in the adapter. when you press the button, it should give 3.3v. I also have a fully working KAV10 motherboard, it behaves just like that.

See page 31 for 51ON# (17v comes from VIN trough PD4 and PQ1.

Yes it is ok. After pressing the power button, it goes down to 0v then 3.3v.
