Description Rudi Lippert 2007-04-25 01:04:13 UTC
Most recent kernel where this bug did *NOT* occur: none known
Distribution: Gentoo
Hardware Environment: ASUS laptop with Intel 82801 chipset

Problem Description: When the system is suspended to disk, the battery state is
not refreshed afterwards, i.e. if the battery is inserted while the computer is
powered off, ACPI does not know it's there or how full it is.

Steps to reproduce:
- cat /proc/acpi/battery/*/state
- Remove battery
- echo -n disk > /sys/power/state
- Insert battery
- cat /proc/acpi/battery/*/state (battery is still reported as not present)

Comment 1 Vladimir Lebedev 2007-04-26 10:02:13 UTC
  
Please try 2.6.21 kernel and the last 'mm' kernel, attach acpidump and  
dmesg output. Please 'cat /proc/acpi/battery/*' few times and attach the 
results.

I cannot change kernels at the moment, but I will do some more testing
tomorrow.
Comment 3 Vladimir Lebedev 2007-04-27 02:23:43 UTC
 
Please attach 2.6.20 dmesg output.

BAT0/* with 2.6.21-rc7-mm2, after removing battery in suspend

In this case, ACPI seems to actually notice the battery is missing, which did
not happen in 2.6.20 or 2.6.21. When inserting the battery during suspend with
2.6.21-rc7-mm2, the behavior looks just like 2.6.21 to me. If you want me to
attach the other acpidumps for the mm kernel as well, let me know.
Comment 17 Vladimir Lebedev 2007-04-28 06:45:27 UTC
Please perform the following testing:

a)
remove battery
suspend
insert battery
resume
cat /proc/acpi/battery/*/* and /proc/acpi/ac_adapter/*/*
unplug/plug AC cable
cat /proc/acpi/battery/*/* and /proc/acpi/ac_adapter/*/*
send 'cat' output and dmesg

b)
remove battery
suspend
insert battery
resume
cat /proc/acpi/battery/*/* and /proc/acpi/ac_adapter/*/*
wait for 5 minutes
cat /proc/acpi/battery/*/* and /proc/acpi/ac_adapter/*/*
send 'cat' output and dmesg

Please test both kernels - 2.6.21 and 2.6.21-rc7-mm2.
Comment 18 Vladimir Lebedev 2007-05-17 13:13:47 UTC
Please test with 2.6.21, 2.6.22-rc*, or something later.
If this issue still exists, please re-open this bug report.

Can you please try 2.6.22-rc3 with the patchset from
http://www.sisk.pl/kernel/hibernation_and_suspend/2.6.22-rc3/patches/ applied?

output of patch -p1

For some strange reason some of the patches failagainst a vanilla 2.6.22-rc3.
Should I apply them anyway?

Again, the battery is only detected after toggling the AC adaptor

Battery is not detected at all.

To me (dummy), everything looks the same as with 2.6.21.
Comment 28 Rafael J. Wysocki 2007-08-08 10:19:15 UTC
Can you please try the 2.6.23-rc2 kernel?
Comment 29 Adrian Bunk 2007-09-16 13:41:51 UTC
Please reopen this bug if it's still present with kernel 2.6.23-rc6.
