My housemate loves his Samsung R720 but it kaput itself a few days ago. He is now pining and trying to fix it. He has tried the 'usual' tactics of resitting the RAM, removing the hard drive, holding down the button, attaching the lappie to an external monitor. Nothing works. The lappie powers up, doesn't squeek, he can hear the hard drive spinning but nothing else happens. From what we have found on the net, the mobo is the likely culprit? His lappie is several years old and it has given him a good run for what he paid. I have told him to send it to lappie heaven, because a replacement mobo will cost several hundred and he is better off buying new. He has looked for any obvious damage to the mobo - there is none and he is not a half-wit about such things. My question to you guys is - given the 'evidence' do you concur that it is a mobo problem, is there anything else he can do and it is best to simply replace an aging lappie with something new?
