T6500, 4gb DDR2, 500gb HDD, Windows 7 64bit. Left the laptop running one night and when i woke up in the morning it had a black screen and would not respond to any buttons. Tested the charger (full voltage), tested the battery (fully charged), tested the ram, HDD, monitor, all in functional order. The connector for the power converter was also electrically tested and works flawlessly. CPU chip does not appear to have any bad connections under visual inspection with a microscope. I don't know enough about to computers to continue on the hunt for problems. Is there any way to test the CPU to make sure it is functional or is there anything that could have fried while the computer was running? How could i test the motherboard? I have two other computers to im not in a hurry to figure out what the issue is but i would like to see if i cant get this computer to work again.
Side note when the computer had a low battery a red light would flash on the computer. This status light does not even come on.
Any help or suggestions? I am new to laptop disassembly and testing so if you would like me to provide any pictures or more information let me know.
Thanks
