t21 fan

[slotsca]

The fan on my T21 will run when it is first turned on but stops as soon as windows starts.and will eventualy shut down due to over heating. I tried updating bios to default setting, No GO does anyone have a suggestion?

Purchase a new T22 fan(it will work) on ebay it cools better.

there is some thing wrong of CPU temperature detecting.so the fan never run.I think the fan is working good!you should check motherboad

Try to download speedfan (google it) and make your fan run at all times to keep things cool. Not the best solution but it beats paying $$$ for a new board.

The fan should only run for a second at boot. The unit is most likely shutting down in 5 - 15 minutes after botting up. Is that correct? It isn't warm enough for the fan to spin. If it is shutting down in that timeframe it is almost always a bad system board.

I have tried a new fan with no different result. I now have it narrowed down to a bad connection, cable or at worse case motherboard.
Thanks for the suggestions, I will post a reply when the problem is solved.

From what you're describing it is a bad board plain and simple. No cable in that laptop will cause the issue. The only thing to "check" would be to make sure the memory / cpu / etc. are securely seated... The only other thing it could be is spyware. Some spyware will power the unit right off.
