My acer aspire one does not show any sign of life. No charging lights, no sin of any life... tried removing teh battery pressing the power on button for more than 20 seconds, removed and put in the RAM... no luck
Probably needs a replacement motherboard or at least a new charger. For an Aspire One probably not worth spending money on new parts, just get a used working model of the same one as yours and swap your hard drive into it.
