My dad has kindly given me a work mates laptop to fix. neither know anything at all about computers. Description of problem was "tried connecting a printer up and now it doesnt work". When i tried to power it up the green power light shows and thats as far as it gets no bois screen nothing. A local computer shop the guy took it to said it was the motherboard and was gonna cost £270+labour to fix. If it is indeed the motherboard how easy is it to swap out. p.s. its an acer dont have the model number to hand.
