I say open up Firefox to a blank webpage, open task manager, and then don't touch anything. Sitting idle Firefox shouldn't use more than maybe 5% CPU. If it's using more then something wrong.
As for the sleep issue and the mouse, mine does about the same (I upgraded to win7 the other day). I saw elsewhere that the latest ATI drivers are a little buggy with win7 and are causing the computer not to resume. I think the mouse is related to the touchscreen hardware. I have to turn the touchscreen off to get OneNote to pick up the pen properly, and while it's off I never have any problems with the mouse jumping. I think the screen is picking up erroneous touches.
Hey guys just got a new tx2z (2.3ghz w/ 4gb of ram) and it runs fine with windows 7 though there are a few things I just can't seem to fix:
CPU usage is always around 50-60% though I did not install the HP media center or any of the other bloatware that came with the computer. Looking at the resource manager with just MS Word & Firefox running, I noticed that Firefox is always around 30-50% of the cpu resource. Does that sound right especially with a flash based website going?
Fan is always going though it's on power saver mode & everything is set low (gpu usage, etc.) when plugged in. Probably due to the constanly high cpu use.
Computer will only come out of sleep when the laptop is plugged in using the original windows 7 drivers and the newer ATI drivers.
Mouse cursor occassionally jumps around, though I'm certain it's a driver issue (got it working before I had to format again).

List what firefox extensions you're running and what firewall and anti-virus you're using, please.

nightsgt,
I have a "good old" XP system that shows the exact same CPU load behavior when visiting Flash-based sites using Firefox 3.0.13 and the Adobe Flash player 8,0,22,0 plugin. When I visit sites that use a lot of Flash animation, the CPU goes to 50%. That's perfectly "normal", since the CPU has to do all the work to perform the Flash animation. So it has nothing to do with Windows 7 or Firefox. It's just the way Flash uses the CPU to "do its magic".

Hello nightsgt,
try using the older ATI-drivers available at HP.
The newer ones directly from ATI seem to be incompatbible causing software-rendering (at least one my machine).

I've used Windows 7 RC1 for 1 month and I've just finished my 1st month running Win7 RTM with the newest ATi 9.8 beta drivers, the n-trig win7 drivers, and no Touchsmart software. I've never experienced higher than normal CPU usage.
I have a TX2-1270us (2.2 Ghz RM-75 CPU) with 4GB RAM and the 5400rpm 500GB hdd.
Aside from the screen rotation issue, I've had no problems.

I fixed the screen rotation issue by installing the latest ati drivers...

Strange.
Does 3D-acceleration still work?
An easy way to test: Just open the ATI CCC and check whether there are animated previews of the 3D settings available.
On my tx2 it did not after I installed the latest drivers.

yeah it works fine, try un installing the ati drivers and re installing. I'm using the 64 bit windows 7 drivers btw.

Screen auto-rotation still flips 180 degrees instead of following the Windows 7 orientation settings.

Hmm - I uninstalled the old driver, installed the new one and it worked.
However, since today it suddenly does not work anymore.
Strange...
//EDIT:
Which versions are you using?
9.6? 9.7? 9.8? The version with 46.9 MB or the one with 84.8 MB? Or the one with 92.3 MB?
