Re: [Pm-utils] No battery info after suspend

[Don Harden]

Hi Holger,
Yes,  I do have the latest the BIOS.
No,  reloading the battery module does not restore the 
/proc/acpi/battery/BAT0/files

Hello,

I have the following:
  HP Pavilion dv7 laptop with an Intel Core2 Duo T9400 and 4 GB of RAM
   Fedora 10  2.6.27.15-170.2.24.fc10.x86_64
   pm-utils-1.2.2.1-2.fc10
   hal-0.5.12-14.20081027git.fc10

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

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?
    

Does unloading->loading the battery module after suspend cure the
problem? Do you have the latest BIOS for your machine installed?

Regards,
 Holger
