Question about Compaq Presario 1510 (White) 15 in.CRT Conventional Monitor
Compaqs are notorious for having the heatsinks come loose of the processor. I have a Presario V2000 and after about a year it started to overheat. The fan worked overtime to try to compensate but it's just too small to overcome bad thermal contact. Problem is caused by the use of a thermal pad fromt he factory and flimsy metal tabs to hold the heatsink onto the motherboard. Eventually through normal wear the heatsink wiggles a little loose and you do not get good contact with the processor for proper cooling. Good news is it is pretty easy to fix. Mine was not very difficult to remove. BE SURE TO HAVE POWER UNPLUGGED AND BATTERY REMOVED! Just take all the screws out of the bottom of the laptop and you will see the fan and heatsink combo. There are some screws holding it onto the motherboard. Remove them and carefully remove the fan/heatsink. Carefully remove what is left of the thermal pad (grey square of rubbery stuff on the bottom of the heatsink). Apply a layer of "Arctic Silver" or equivalent cooling compound to the area where you removed the thermal pad. The arctic silver is better at transfering heat and will also help keep the contact sufficient since it is more of a fluid. Be sure the get the heatsink back on as tight as you can, but be sure not to warp or break the motherboard.

Deborah67, To answer your question about what the tech was referring to with the term ?lamp? it was probably the florescent backlight that lights up your LCD panel. While that could be adding to the problem I haven?t seen one cause a laptop to overheat and shutdown by itself. Try a few experiments and let us know the results: -Try running with the A/C adaptor without the battery main batter installed. If it stays on longer or stays on then the battery or charging circuitry is part or the entire problem. -is the fan on the back of the laptop running just before the laptop shuts off? If it is can you feel warm air coming out? If not then that too could be the cause or part of the cause. -Try turning the LCD brightness down, if that doesn?t cause the computer to run longer than the LCD is probably not the major cause of the heat. -What type of surface is the laptop resting on? -How long does it take to overheat and what are you running when it does? -Flip you laptop over and give us the Model number listed there. That will give me more info about the processor installed. That along with the battery charging process generates much of the waste heat in a laptop.
