I have the following:
  HP Pavilion dv7 laptop with an Intel Core2 Duo T9400 and 4 GB of RAM
   Fedora 10

Everything runs great including suspending, hibernating and resuming except that when the laptop resumes from a suspend or hibernation there is no battery info:   
  {0}duder:/home/don > cat /proc/acpi/battery/BAT0/alarm
  present:                 no
  {0}duder:/home/don > cat /proc/acpi/battery/BAT0/info
  present:                 no
  {0}duder:/home/don > cat /proc/acpi/battery/BAT0/state
  present:                 no

Before a suspend or hibernation  and resume the battery info is as expected:  
  {0}duder:/home/don/bin > cat /proc/acpi/battery/BAT0/info                                                
  present:                 yes                                                                             
  design capacity:         5100 mAh                                                                        
  last full capacity:      4800 mAh                                                                        
  battery technology:      rechargeable                                                                    
  design voltage:          14400 mV                                                                        
  design capacity warning: 240 mAh                                                                         
  design capacity low:     144 mAh                                                                         
  capacity granularity 1:  264 mAh                                                                         
  capacity granularity 2:  3780 mAh                                                                        
  model number:            Primary                                                                         
  serial number:                                                                                           
  battery type:            Lion                                                                            
  OEM info:                Hewlett-Packard      

It does not matter if the laptop is running on AC power or the battery

Booting with every combination of turning acpid on or off and turning the pci=noapci  kernel flag on or off  has no effect.

I spent a good deal of time Googling and searching the pm-utils archives but found no solution.

I've also tried the suggestions on the HAL Quirk site, http://people.freedesktop.org/~hughsient/quirk/index.html  but still no joy.

Any ideas to get my battery info after a resume?

Thanks for your time.
