Laptop shuts off by it self???

[madster93]

So, I'll just be using my laptop normally and it will turn off on its own.  Even when it's fully charged.  I have a Dell Inspiron and it is over 2 years old.  It didn't usually happen that often, but now everytime I'm on the computer, it'll shut down after 30 minutes or so. I have Norton Anti Virus and there is no virus that I'm aware of.  Help?

Overheating...
DLoad and install and run SpeedFan...
Post back with your temp readings...

Ah thank you.
The temp readings were:

temp 1- 67 degrees Celsius
core- 65 degrees Celsius
and HD0- 40 degrees Celsius

So my laptop shuts down due to overheating?

Temps are OK, but of course it's still on.  Maybe the cpu fan is choked with dust.

Try using laptop with a direct connection to the adaptor by removing the battery and  check your 2 year old laptop if ventilation for fan is block from dust. Better yet an internal cleaning using the right procedure might clear your problem.

Okay, Ill try and check the fan for dust.
Thank you both for your suggestions!

Shining a flashlight into the fan exhaust port should give you a good idea before opening it up.
