Hi All,

Checking _BST results in the acpi_battery_bst_valid() (acpi_battery.c) 
always brings about 'not present' state if I have plugged AC adapter 
as result of comparing battery state with ACPI_BATT_STAT_MAX (because 
1.90 and 1.50 bioses use bit7 as a 'AC plugged' sign).
Is this behaviour a ACPI BIOS bug? Could ACPI BIOS conforming to the 
specification report battery state more than ACPI_BATT_STAT_MAX 
(==0x7 now)?
Currently I've wrapped _BST method by masking returned state with 
0x7f. The same is possible for the acpi_battery_bst_valid() function 
in dev/acpica/acpi_battery.c
Which way is right?
