I think the power app is making a guess - ie it's calculating the power
when full and working out how much it's using over a period of time
rather than any hard ACPI data as would normally be the case, but at
least we get a rough idea of the time remaining now which is progress.
The underlying problem is still with the hardware which given HP's
support of Linux elsewhere is a surprise.

Title:
  HP G62-a50SM battery status

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

Bug description:
  Ubuntu 10.10 64bit.
  Hardware: i3-350m, ati radeon hd 5470

  Ubuntu battery indicator cannot estimate time to charge the battery
  when charging. Disconnecting the battery causes it to say the battery
  is charged despite it is not. Turning the computer on without the
  adapter plugged in results in the message that it is estimating time
  remaining.

          When turning the computer on with the adapter plugged in:

  cat /proc/acpi/battery/BAT0/state 
  present:                 yes
  capacity state:          ok
  charging state:          charging
  present rate:            unknown
  remaining capacity:      1790 mAh
  present voltage:         unknown

  cat /proc/acpi/ac_adapter/ADP1/state 
  state:                   on-line

          After disconnecting the adapter:

  cat /proc/acpi/battery/BAT0/state 
  present:                 yes
  capacity state:          ok
  charging state:          charged
  present rate:            unknown
  remaining capacity:      1875 mAh
  present voltage:         unknown

  cat /proc/acpi/ac_adapter/ADP1/state 
  state:                   off-line

          When turning the computer on without the adapter plugged in:

  cat /proc/acpi/battery/BAT0/state 
  present:                 yes
  capacity state:          ok
  charging state:          discharging
  present rate:            unknown
  remaining capacity:      1704 mAh
  present voltage:         unknown

  cat /proc/acpi/ac_adapter/ADP1/state 
  state:                   off-line

          After plugging the adapter in:

  cat /proc/acpi/battery/BAT0/state 
  present:                 yes
  capacity state:          ok
  charging state:          discharging
  present rate:            unknown
  remaining capacity:      1576 mAh
  present voltage:         unknown

  cat /proc/acpi/ac_adapter/ADP1/state 
  state:                   off-line

  
  cat /proc/acpi/battery/BAT0/info gives following output 

  present:                 yes
  design capacity:         4400 mAh
  last full capacity:      4262 mAh
  battery technology:      non-rechargeable
  design voltage:          10880 mV
  design capacity warning: 512 mAh
  design capacity low:     299 mAh
  cycle count:		  0
  capacity granularity 1:  100 mAh
  capacity granularity 2:  100 mAh
  model number:            
  serial number:           
  battery type:            LiOn
  OEM info:                HP

  
  It seams that acpi doesn't return the present rate of charge/discharge so the system can't estimate remaining time to charge/discharge, and the adapter doesn't change its status until reboot when connected after discharging unless the computer was booted while it was already plugged in.
