My beef with compbatt.sys is that it kicks in during the boot process and apparently queries the internet about my laptop's battery. And, as my IE 7 currently doesn't work (Can't display the requested web page, or any other...), compbatt.sys conludes that I have no battery installed and puts a message to that effect in a box on my task bar. But, I've found that you can just click on the message and then on "disable" so it disappears. As for the battery, it works fine and charges normally and my laptop runs fine.
This all began yesterday 6/26/10 after I downloaded MS updates including their Update to root certificates KB93115 that, unfortunately cannot be removed. The latter interacts with ACPI which controls a number of components, including batteries for, according to Microsoft, enhancing users' experience. I've just blown some 10 hrs on this!
