Hi all,

I’ve got a clients laptop at the moment as he was complaining it was slow which it was (really slow). So was looking round and pulled up the system info and the CPU, Pentium M 1.8Ghz was showing to be running at 92Mhz ? :o

It only does this in windows. (windows xp). In the bios it shows up perfect, minimum clock speed of 800mhz :s
Anyone got a suggestion or know of this problem.

Thinking it must be the CPU but also thinking maybe the board has gone funny.

Thanks

It could be the cpu being throttled when not doing anything too demanding, much like Speedstep. Check the Bios and see if anything like this has been enabled
 
Here are a couple screenshots of CPUZ and the system properties..

Its a Dell laptop and we have updated the BIOS to the latest version..

We've tried disabling SpeedStep but its not that because it stays underclocked even when you are trying to do anything.. It takes about 10 minutes to boot up as well!
 
It doesn't look like a BIOS problem because we updated that with the latest version and checked all the settings in there...
 
try coretemp or something first to check cpu temps, the fans might be clogged with dust causing it to overheat.

another thing to try would be the restore to factory state thing for OS.

Now i'm very new to these things and certainly don't know if this applies to laptops but i recently disabled speedstep for my pc and then soon found out that i needed to disable something called C1E to disable speedstep correctly.
 
We have already tried resetting the BIOS and that made no difference, we tried turning off SpeedStep but that didn't do anything..

I took the laptop apart to check the cooling and it was all working fine.. However I think the board thinks the chip is overheating. The fan stays on permanently and the heatpipe cooling the CPU never gets hot.. I think there must be something wrong with some sensor on the board. Coretemp and TAT don't work with this CPU as its not a Core CPU.
