Dell Inspiron 1525 Overheating(?)

Hello Everyone,
I'm having a problem with my Dell Inspiron 1525 where the system slows to a crawl for what appears to be overheating. The system boots up fine and seems to run fine for the first few minutes I'm using it but after that I can hear the fan turning faster and faster as the system gets slower and slower. The first time I noticed this I realized it was probably overheating as the laptop was sitting in its carrying case with no ventilation on the bottom. However, I'm still having the problem even when I've got the front of the laptop propped up a few inches to give it plenty of ventilation. The system could be running fine 1 min. but once I start running another application the fans start whirling and the system slows to a crawl. The most resource hungry application I use is Dragon NaturallySpeaking and the system almost always slows when I run it. And again, the fan always get much louder when the system slows like this.

Any idea what could be causing this? The total CPU usage is usually around 25% (per task manager) when I'm experiencing the slowdowns. The laptop has an Intel T5800 2 GHz CPU with 4 GB of RAM.

Thanks in advance for any info you can provide!

you need to get a laptop cooling pad for starters, then take a cover off the back while it is on the pad so you can cool the laptop down. you can then download a program called speed fan. its free just google it.

You will then find out if the processor is running hot or not (60-100C). if it is hot then it could be the heatsinc, i had a similar problem with mine, i took the heatsinc off to replace the thermal paste and clear the fan out (which hopefully thats all yours needs)

Try that first, if not let me know and i will tell you the next step.

Hope this helps

Hello,
Thanks for the reply. I installed and ran Speedfan and I'm still having problems with the overheating. At one point the temperature for both cores was 122°F and a message appeared in Speedfan that the system was "ready for suspend" then read "APMRESUME message received" then resuming from suspend. What are these suspend messages referring to? I didn't RTFM yet :-(

speed fan doesn't cool it down just tells you the temps. im not sure what the messages are, you need to clean the fan as i think that is blocked, try not to put the laptop on until you have done this as it can cause damage in other places.

I have the same laptop and have had overheating problems for a long time... Under the one year warranty I brought it in and I know they repair things related to the temperature problem (rethermalated it - I think that is what the receipt had said) and it still gets exceptionally hot... The overheating causes other problems like the plastic on the hinges for the screen getting hotter than normal since they are near the vent. I had the hinges crack a long time ago and had to replace the screen case. I am also very careful with my laptop and do not travel with it..it is mainly a countertop pc. I hope you can figure out the issue...I would love something other than thinking it is just a dud of a laptop.
