I'll report a similar problem. I'm using Linux Mint 12 (based on Ubuntu
11.10) with the default Gnome 3 interface. On approximately every 3rd to
5th wake-up from suspend (using the default pm-suspend) the system
reports not 1 battery but 2 or 3 with the extra 1 or 2 having 0 charge.
This used to cause the machine to throw up a "Critical battery" alert
and it would hibernate, it would normally not come back from hibernate
(I'm not using tuxonice, I have the default power manager), it would
partially un-hibernate and then lock on a black screen.
To avoid this problem I changed the system setting 'critical battery
action' from 'hibernate' to 'nothing' so it doesn't go into hibernate on
a critical battery warning. For Linux Mint 12 this is found using the
"dconf Editor" under "org/gnome/settings-daemon/plugins/power”.
I have an E6420 with NVIDIA NVS 4200M, 64bit Ubuntu.
I've produced the following bug notes manually, I tried running apport
but it reports an error ("The problem cannot be reported: This is not a
genuine LinuxMint package") no matter how I try to call it.

I'm a long-time Linux user (back to Slackware and Diamond Stealth video

E6420 is my only laptop and I'd love for it to work reliably.
