Public bug reported:
Running Ubuntu 9.04 Jaunty, latest updates applied, kernel
2.6.28-11-generic.
Using HP Pavillion DV7-1034ca Entertainment Notebook PC.
When I first boot up the computer it recognizes the battery fine.
However, if I put the computer to standby and then resume operation, the
battery is no longer detected.
cat /proc/acpi/battery/BAT0/state returns:
present: no
but acpi -a still detects AC power properly.
