Description Jason Bouzane 2004-03-04 17:09:18 UTC

Distribution: Mandrake 
Hardware Environment: Dell Inspiron 5150 
Software Environment: 
Problem Description: Battery Removal Undetected 
 
Steps to reproduce: Remove battery; cat /proc/acpi/battery/BAT0/state 
 
This produces the following output, which is identical to that when the battery 
was present: 
present:                 yes 
capacity state:          ok 
charging state:          unknown 
present rate:            unknown 
remaining capacity:      6450 mAh 
present voltage:         16462 mV

did you notice if interrupt is generated when you remove battery?
eg. compare 'cat /proc/interrupts' before remove and after before

Comment 3 Jason Bouzane 2004-03-14 22:29:00 UTC

I can't really tell with the output. Maybe you can, but I don't think there's 
enough information here to tell for sure. Here's the diff before and after:

I'll try to put a printk in the ISR and see what happens.

Comment 4 Shaohua 2004-03-14 22:33:48 UTC

ok, according to your diff file, no interrupt when you remove battery.
please check if press power button can generate interrupt?
eg.check if the value of acpi in 'cat /proc/interrupts' changed

Comment 5 Jason Bouzane 2004-03-14 22:37:09 UTC

No, the power button does not generate an interrupt. Nor does the suspend 
button or closing the lid. The ACPI interrupt count is, in fact, at zero.

Comment 6 Shaohua 2004-03-14 22:40:25 UTC

ok, it likes an interrupt issue instead of a battery issue. please attach the 
dmesg and cat /proc/interrupts. thanks -- shaohua

FYI: in light of this information, bug 1752 may be related to this.

Comment 10 Shaohua 2004-03-14 22:52:10 UTC

yes, it's the same issue.
