Hej

Jeg har en laptop med apm bios version 1.2. Mitt problem er at engang imellem så gider kærnen give information om mitt batteri men for de meste ikke. Jeg kiggede lidt i killdekoden og fandt føljende:

$SRC_ROOT/arch/i386/kernel/apm.c:~1242
2) APM flags from APM Installation Check (0x00):
 bit 0: APM_16_BIT_SUPPORT
 bit 1: APM_32_BIT_SUPPORT
 bit 2: APM_IDLE_SLOWS_CLOCK
 bit 3: APM_BIOS_DISABLED
 bit 4: APM_BIOS_DISENGAGED

Min værdi er 0x03 betyder de at min apm er disabled?
Her kommer lidt apm --debug:

APM BIOS 1.2 (kernel driver 1.9)
AC on-line
Using device 0x0a86, 1.9: 1.2
APM Flags =      0x03; AC Line Status = 0x01
Battery Status = 0xff; Battery Flags =  0x10
Battery %age   =   -1; Battery Time   =   -1, use_mins=0

og lidt dmesg
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.9)
