laptop functions but after a regular shutdown it wont start back up no fans no sounds no nothing. but after a wait say 45 min or so it turns on just fine and will remain on even after restart. but once shut down it will do this again and not start i reset it to factory specs [reformat] and it still douse this so it obviously isn't software definitely hardware. My guess is overheating or a short somewhere any ideas? oh also not power supply related as it starts without charger with battery, but shows same issues when shutdown.
