This Bug affects me too. I'm using 11.04 on my ASUS X53E laptop.

Here is how I can produce the bug:
1. Laptop on battery and with plenty battery left
2. Let the laptop hibernate
3. wake it up again
gnome-power-manager's battery applet shows the battery as critical (0%)
after 30 seconds when the applet refeshes again, the battery shows the correct level again.

cat /proc/acpi/battery/BAT0/state
shows the correct state at all times.

This bug is a problem when I have "suspend on critical battery" turned
on, because the laptop wakes up from hibernation and goes right back
into to suspend. This doesn't happen for me on suspend.

Title:
  After hibernate: Battery not correctly recognized/displayed in Panel
  applet

Status in “gnome-power-manager” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: gnome-power-manager

  When a laptop is running on power from the power adapter (the battery
  is not in the device) and the computer is then hibernated, the battery
  is not recognized after putting it in (during hibernate).

  More detailed report/how to reproduce:
  I almost never shut down my laptop, I always just hibernate it. And to preserve the battery, I take it out of the computer when I'm at home and working on power from the AC adapter. So it happens often, that I hibernate the computer while on power from the AC adapter and then put in the battery and disconnect it from AC power when I have to work in the train... When I wake up the comp from hibernation, the Power Manager Panel Applet still shows the symbol for 'no battery in device and running on AC power'. I have then to restart the computer to get the correct Panel Applet symbol ('running on battery').
