- Here is what is troubling me with the incident....the laptop will not power up. Look at your system varefully, is there easy access to the heatsink of the processor? If there is an access door that gives you access to the heatsink, unscrew the heatsink hold-downs and gently lift the heatsink away, clean the old thermal paste off the heatsink and on the head of the processor. Apply new thermal paste, about the size of the head of an eraser and spread it across the surfaces thinly. replace the heatsink and tighten down. There is no way of telling at this point if the mainboard is terminal. All you can do is try the steps and hope that they work. There is one more thing to do, remove the Cmos battery for 30 minutes or longer to make sure everything gets reset. If the laptop powers up, boot into the bios and the time and date will have to be reset before loading anything else. Good luck with it.
