a friend gave me an averatec 2300 series laptop that was busted. it charges the battery and when i press the power button the power light comes on and the CD drive can be opened and spins up with a disc in it but nothing else turns on no fan, no built in screen, no attached monitor,or other lights. i am trying to practice my electronic troubleshooting/repairing ability so it doesn't mater if i fry this thing to a crisp. i know that the problem lies on the main board because i have eliminated the screen/inverter and the fan does work if i pull it out and use a 9v battery to power it. so my main question is how can i troubleshoot this to a specific chip or component on the main board? if i had to guess i would say that (because this thing has a nvidia north and south bridge)the north bridge should handle the graphics so that is where my problem lies.thax in advance for any help.
(also if i do find it is a major IC like one of the bridges I'm going to try and replace it, time to try my hand at reflow soldering)
