Help with T2500 Clocking down for no reason.

Lately, I have noticed that my new Compal HEL80 pauses every now and then. The cursor will hang for a moment then basically teleport to the place where it should be if it had not frozen. When I play music or movies the sound sometimes begins to stutter and slow down then it goes back to normal. At first i thought maybe it was a HDD error but I ran scan disk and defrag and the problem still persists. I ran CPU-Z and found that my T2500 is only going @ about 995 MHZ. I'm not too sure why it clocked down. I first noticed it when I was transferring old media from my PC to the laptop. My laptop is plugged in so its not clocking down to save power... anyway heres a screenie of CPU-Z's reading. Any help would be appreciated.

 

It clocks down when it's theoretically not doing much. It's a power-saving measure. You most likely just have to adjust your power properties so that it's running at full speed when plugged in and it'll work as you expect.

 

Thanks for the quick reply, but I just played a game of F.E.A.R. in windowed mode while watching CPU-Z. The clock speed only jumped up every few minutes and even then it only spiked, it went back down immediatley. For example, right now as I'm typing this the letters are lagging behind my actual typing but will appear after a second or two. I know the T2500 is supposed to slow down to save battery and all that but so much so that it begins interfereing with typing and mouse movements? Or is it not my cpu at all?

Edit: I just started transcoding video and the same thing happens, it stays for the most part at 997MHZ and it will spike every now and then. Every time it spikes and changes clocks everything freezes then continues as if nothing happened. In F.E.A.R the sound would lag at some points and I wasn't able to move my pov with my mouse and whatever direction I was moving in before the freeze, I would continue to move in even after I started pushing in another direction.

 

If your computer pauses, that's nothing to do with the clock speed.
As said above, it automatically clocks down when full CPU speed isn't needed. (And in FEAR, you probably had VSYNC or something enabled, so it didn't need to up the CPU speed.

So yesm it's nothing to do with your CPU.

But the freezes and lagging text is *not* supposed to happen, regardless of clock speed. Check for spyware/adware/bloatware/othernastykindsofware
Then check that all drivers are updated, that you have an updated bios, check the Windows event log.

That should get you started.
