Have you checked in Task Manager which program(s) is (are) causing this heavy cpu usage? If not, go check this and post the name of the program or search on google for the program. If it's not a necessary program you may want to unistall / deactivate it.
In an older post it was mentioned that in some cases the driver for the built in Motorola modem caused pretty much CPU load.
Another way to check for the CPU usage: Win key + r, then type in perfmon and hit Enter or alternative start the Task Manager, click the tab Performance and then click on Resourcemonitor. The then following window will give you several information about CPU usage, HDD load, ...
I have my brand new tablet and i completely love all the features it has. My problem however is that it is incredibly slow. I notice this more on battery than when plugged in.
I checked my CPU usage and it is 100% - 97% usage, it has been idling about 12 minutes after boot. Im absolutely fanatical about boot programs. I immediately uninstalled the norton to free up that usage... no luck though.
Im wondering if this is a known issue, particularly when on battery?
Looks like its back to the store in the morning, unless anyone has any help.
Thanks!

Off the top of my head and without knowing which programs you installed, and since you say it is anew computer, mu guess is that it may be some disk caching/indexing.
I agree with Travis too. Run task manager and see which process is using the most of your CPU.

Did you go through MSCONFIG and disable unecessary startup apps yet? The default setting for Vista swap files is 'Windows Managed' you could try setting up a permanent one swap file to see if you get any improvements.
I was getting the same problems with performance. What hardware is your TX2z using? My TouchSmart was using a 2.1Ghz Turion with 3GB RAM (the lowest config). I've already sent back my TX2z to HP for a faster replacement (2.4Ghz CPU & 8GB RAM). I'll see if there's improved perfomance when I get the thing back.

I'll second what simply jeff said about the swap file.
Set your swap file size to at least 1.5 times the amount of ram youhave, so for 4 gigs, a permanent swap file size of 6000 to 6100mb should be fine.
I had actually been thinking about this post and it dawned on me that after the last time I installed a newer Windows 7 build I didn't set my swap file size. I too was having considerable disk activity for at least 10 minutes after bootup. I set the swap file to 6100mb and disk activity now ceases in under 5 minutes after bootup. Its funny becasue its USUALLY something I always do but just forgot this time.

Well the built in superfetch in Vista kept my hdd reading / writing for about ten minutes after booting and caused some CPU usage (at least no 100%). I turned of this feature and the readyboost feature in services menu and now my hdd is idling after about two to three minutes. I don't care if a program needs a few more seconds to load now and maybe I'm cheating myself but for me it seems that turning of the superfetch increased battery time around 20 - 30 minutes with the 8 cell battery.
Another thing that keeps the CPU and HDD working while they're supposed to idle is the daily System Restore Point creation. On my machine it starts working after about 10 minutes in idle when it is plugged in. Didn't recognize that SRP creation started in battery mode so far.
Again I would suggest to check what's causing the CPU load. If it's the indexing of Vista you may want to let it run through all the files once and you're done more or less.
