Having problems with your Dell Latitude C640 Notebook ?

Laptop keeps shutting down, both fans not working

\015 Hello, I have a Dell Latitude C640 that has worked perfectly for a very long time. But all of a sudden one day when I turned it on it kept shutting off after just a few seconds. If I try to turn it on with only the AC adapter connected (no battery) it usually requires that I push the start button a few times before it will turn on, but then it will shut down after a few seconds. If I try to turn it on with just the battery connected (no AC adapter) it will turn on the first time I push the start button, but then it shuts down after a few seconds. After a few times of trying either of these methods to start the laptop it won't start at all and I will need to wait a while before trying again. Regardless of which way I get it to start, I notice that both the CPU fan and case fan are not spinning at all. What would be common to both the CPU fan and the case fan not spinning at all? Is it possible the laptop is overheating in just a few seconds, and this is what is causing it to shut down?\015\012Thank you!\015
