Hello, I have a Dell Latitude D531, it runs for a few seconds at max rpm then stops and keeps repeating, after a few minutes it shuts off, sometimes the fan doesn't spin at all. I have tried cleaning the fan, removing the CMOS battery and replacing the old thermal paste, it didn't help. Any idea how I can fix it?
Is dit een goede vraag?

So the issue was that there was a thermal pad mixed with thermal paste on the gpu, I removed the thermal paste and left the thermal pad, that fixed it. I received this laptop from a friend a few days ago with the issue that it was shutting off.

@andreiniculae yup. that can do it. People sometimes forget that thermal paste can be conductive. Good job!
@andreiniculae, excellent work! I'm glad you were able to figure it out.

@andreiniculae possible that you are having issues with the tach circuitry on your motherboard. Have you checked the motherboard ? Tried a different fan? Let us know what exact motherboard your Dell uses.

@oldturkey03, thank you!

Can it be a fan failure? Or are there issues on the actual motherboard?
@andreiniculae it could be the fan but I wouldn't hold my breath on that. After all it kicks in with just one speed and then stops. Of course, I would replace the fan first and hopefully that fixes it, but if not you know what you will have to check next. Always go with the simple stuff first.

@andreiniculae, great work troubleshooting. Have you checked your task manager to see if you're running any load-intensive programs?
You can see this by looking at task manager (CTRL + SHFT + ESC). Let's see what that shows and go from there.

@krisrodriguez The issue is not related to intensive programs running, what I am saying is that the fan isn't staying on, it keeps stopping which is causing it to not cool properly, it is also overheating while being idle in bios.

@andreiniculae, Ah! I see. I wonder if it's the fan itself? Maybe the part needs to be replaced?
While you were in there cleaning it, did you check the connectors to make sure that it was connected properly? Sometimes things come loose.
