Precision M6400 overheating
The other day I was converting a video file. I walked out of the room and then when I came back 15 minutes later, my Laptop had turned off. I booted it up and the BIOS informed me that it had to close down due to overheating! I felt underneath and the part just above the DVD-ROM drive was extremely hot. I did the same again with my Laptop and it just shut itself down again after about 5 minutes. I removed the bottom and both the Laptop up and the fans on the bottom are working fine.
Does anyone have any ideas whats wrong? Been thinking of purchasing a new fan kit with heat sink off eBay!!!

Hi Data10,
As the laptop is overheating I would suggest you to follow the steps provided from this link: http://dell.to/XMnMuK
If you feel that the system is getting over heated, and if the system fans are not operating normally, please try updating the BIOS in the computer.
To update the BIOS visit the following website and follow the below mentioned steps: http://dell.to/Mbe3zg
1.Click the above link, enter the Service tag of the computer in the box provided and click “Submit”.
2.In the next page, click drop down arrow to select the Operating System which is installed in the computer.
3.Under category BIOS, click “Get driver” and save the file on desktop.
4.Ensure to connect the AC Adapter to the computer, run the BIOS file.
5.Follow the on-screen instructions to update the BIOS.
6.Restart the computer when prompted.
Please check the functionality of the system and reply.

Before I continue I want everyone to understand I am a certified Dell Technician, and the method to resolve is not something an everyday person should attempt. Please seek a certified dell technician, or repair shop. This requires a tube of new thermal paste and a can of air or mini vacuum.
*If you have either or both fans not working prior to this, now is the time to have replacements handy.
I have owned this unit for two years since I bought it refurbished off eBay, and I have fixed this issue several times. The issue arises from dust/lint that gets trapped between the fan and the heat sink, as wells as, old thermal grease that dries out. The unit need to be broken down to access the processor and video card. Remove both the heat sink from the processor and the video card. Wipe off the old thermal grease and replace with new. The processor heat sink has fines that need to be cleaned before being placed back in. To clean the fins for the video card, the fan will need to be temporarily removed and the dust/lint blown out. Reassemble the laptop, and the problem should be resolved.
Please note, this will resolve the issue but not fix it so it does not reappear. This is a design flaw with how the unit removes heat. The unit may have to be cleaned every 6 months to a year at a time, to fix this issue.
