Dell latitude D600 CPU issue

I have a 1.89ghz intel pentium M 750 cpu chip in my laptop, and it will not read more than 1.40 top speed. I ran the intel ID utility and expected is 1.89ghz but it only registers 1.40ghz. The expected system bus was 533 but reported was only 400mhz. I have the latest bios for the mother board so it is not that. It is not the CPU because I pulled it out and put it in another laptop of mine and BANG it reads at 1.89ghz. Can anybody give me an idea of why the latitude is not reading the full speed? Oh and FYI, I had a 1.8ghz pentium M in the lap top before hand and it also ran at only 1.4ghz.

    Speed step is installed and running, it keeps the cpu peaked out at 1.39ghz but the cpu is rated at 1.86ghz. I will try the Fn key at start up and see what happens.

Is Speedstep installed? This is a utility that adjust the clocking of the CPU. If it is not installed, you can download it from the Dell support site. After you install it, run it and set it to max performance when plugged in to AC power. The stepdown for battery use will slow the CPU to aboout half, but extend the battery life.

Also try running diagnostics to see if there is an error. Hold the Fn key down when you start the laptop. It will test the system and alert you to any errors.

Good luck and let me know how it turns out.

don't worry most laptops nowadays run hot. your CPU will shut itself down long before damage occurs. try elevating your laptop to promote air circulation or place it on a cooling mat.

Be careful if you set it on your lap, some people have had minor burns from laptops setting on their laps for prolonged periods.

It is not the memory causing the issue. You either have a clogged fan and heat sink or a bad fan. This will solve most heat issues with the laptop.http://www.diefer.de/i8kfan/faq.html

Install this software and put the fan on manual high. That should help a lot if the fan is still working.

Dell Latitude 1.6 GHz/512/40GB-processor speed seems to be stuck at 221 mhz regardless of what app I am running. Is there a way to adjust the speed of the processor? Or is the processor bad?


The processor is throttled by a process called speed step. This slows the CPU to save power. The same process is used when the processor overheats, and the system throttles to manage the heat production.
So the heatsink and cooling fan should be replaced as the first step in trying to resolve the process.
