Basically the R500 is owned by a friend, who had previously given it to his son to use for his school work - apparently the son was using it when 'something' happened and it died a death; it's current status is it appears to be constantly rebooting (no POST displayed) when connected to a mains power adapter based upon the status LEDS on the LCD Assembly and also no output to an external monitor (via a direct connection or by a docking station).
I got it handed over to me and thus far I've stripped it down to the bones, given it a thorough good cleaning (including the fan), all non-essential devices (i.e. Wifi Card, Optical Drive, HDD, etc) have been removed, CMOS battery has been replaced, confirmed working DDR3 DIMMs have been used along with 90w mains power adapters, new battery, checked the motherboard for signs of damage/scorch marks (none whatsoever), etc, etc.
I would assume based upon what I'm seeing the system board is dead but at the same time I do see the fan kick in during the constant rebooting cycle so I'm not a hundred percent sure that is the case...is there anything else I can do folks?
Any input is greatly appreciated.
