I just installed the latest power management driver (courtesy of ThinkVantage System Update) and found that al the power-management schemes are gone -- their names are blank!

Furthermore, when I try to enter a new scheme, and save it, nothing happens -- the schemes are still all blank.

How do I get my power schemes back?

PS: I tried reinstalling the latest ACPI power manager and latest Thinkpad power manager. No luck.

You might be best off using Windows System Restore to get your system back to how it was.

After I posted the above, I remembered the following thread. Maybe you will find a solution there.

Oh dear. I did recently install WinDVD, which seems to be related to the problem.

I just tried System Restore, and it said it couldn't restore to the point I requested. Looking at the other thread, I see that there are registry keys in HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies, and when I look there, there are 105 distinct subkeys. So I imagine the problem is that someting, perhaps WinDVD, has flooded the keys; but I don't know how to proceed from there.

Try System Restore from Windows SAFE MODE.

If that doesn't work, by any chance do you have Norton Antivirus installed?

Message: "Restoration Incomplete. Your computer cannot be restored . . . " when you run Windows System Restore

OK, so I went back to HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies and noted that the policies with numbers smaller than 10 appeared reasonable, 10 was empty, and numbers larger than 10 appeared mostly reasonable as well.

Theory: Someone installed a blank policy in 10, and subsequent installs got confused. So I simply deleted all the keys greater than 9 (i.e. numbers 10 through 105) and now the power manager appears to work again.

Strange.

Thanks for the note about Norton AntiVirus.

However, as deleting a bunch of registry keys appears to have fixed the problem, I'm not going to do the system restore at this time

For what it's worth, I foolishly decided to use the Thinkvantage updating stuff. Updated a bunch of things on my T61 running XP. My power manager battery display disappeared.

Called support and they had me install (I think in some cases after uninstalling) several updates.

I used these executables, found on Lenovo's site:

7ku705ww.exe
7kuy03cw.exe
7kvu22ww.exe

One of them was the power manager. I think it took a restart to get things looking like they should.

Asking about the Thinkvantage automatic updates, the support person admitted most of the staff there doesn't use them. After this experience, I feel like if it ain't broke, don't fix it.

I hope this isnt too far off topic- I did a manual install of the new Thinkpad Power Manager Utility and Thinkpad ACPI Power Management driver (the battery icon was normal at this point). Then i did a normal windows update, and upon reboot, my Thinkpad Power Manager battery icon had basically disappeared, becoming transparent and barely visible with a light colored background. Anyone know of a resolution for this Vista Taskbar / Thinkpad Power Manager utility quirk?

I created a new temporary local user on my box, exported the reg keys for the the schemes, went back to my profile, deleted the root powercfg and imported. Worked like a charm! Thank you!

If anyone wants, I will send the .reg file. It's a bit too big to paste here...
