#Help I have a dead T61 I think - small story below

Story / Problem -
Was doing some video converting and DVD compression (I know on a laptop stupid AND it was hot inside) and the laptop if I remember
- video/screen went off and I left it on hoping it would come back (this could have made things worse)
I powered off and then after letting cool powered on and after 30mins or so same thing, and then same thing but 10mins it lasted.... then on trying to boot again (about the 3rd time after problems) it wouldn't boot.
Now no long switches on (no bios / no fan spin nothing)
BUT I DID NOTICE that plugging in the power supply shows the light next to usb's (on right side)
So a light on the right side (which you have to look from the side to see coming on) comes on when connecting power saying to me motherboard can receive power (for whatever than light is that comes on for a second during power plugged in)
