System:
T60 (Core Duo T2400)
3GB RAM
Crucial C300 64 GB SSD
Win7 32-bit

I installed Windows 7 on this machine, swapped in the SSD, and upgraded the memory more than two months ago and the system was working perfectly--or at least I never noticed the issue until a couple days ago.

After I reboot, system performance is poor, whether I'm min/maxing windows, scrolling web pages, or playing flash videos, everything chugs. The machine just "feels" unresponsive as well.

I've tried stopping services and programs running in the background, and I did a system restore to before the most recent Windows patches were released--to no avail.

I was just about to give up and reinstall Windows, when I noticed that the machine was working perfectly again. What had I done? Turns out I had just put it to sleep and then resumed. The problem is reproducible... Every time I reboot, the performance is awful, but if I put the computer to sleep and then resume, it works fine again.

I'm rather puzzled and would appreciate if anyone had any insight into what could be causing this.

All I can suggest is run task manager and see what processes are running and what they are using, before and after sleep.

Thanks for the suggestion. I'll see if there's any differences in the number of processes running. I know from my initial investigation that the CPU usage reported by task manager was the same before and after sleep, but I didn't see if any processes were terminated.

I suspect it's either something to do with the CPU throttling or the ATI graphics drivers acting up, since the slowdown is most noticeable when doing graphically intensive tasks (rendering web pages, compositing windows, etc.). Boot time is still very fast, as one would expect from an SSD... less than 20 seconds.

SOLVED:

I ran the Lenovo updater and it seems to have fixed the problem. I'm guessing that the power manager was the source of the trouble, as it was the only thing that got updated that might have had an effect on system performance.

Thanks... I should obviously have run the updater before I posted here, but I thought it was a long shot!

How do you run the Lenovo updater?

Thanks

It's called ThinkVantage SystemUpdate (TVSU).
It's available in a version for Windows 7 (V4.0), and for older windows versions (V3.14).
