The net result is that on Linux ACPI battery is missing. In the
_REV test BIOS workaround, a SMI event was added to ask for battery
information update.
Hm. Why does only asking once not result in us seeing the battery?
I'm not sure, this is all I was told about the difference in behavior
with Windows that prompted this bios workaround. Looking through the
kernel log, i'm wondering if maybe
75646e758a0ecbed5024454507d5be5b9ea9dcbf will actually have fixed this.
Alex,
What was the last kernel validated on the 7*37 family? Can you see if a
kernel that includes 75646e758a0ecbed5024454507d5be5b9ea9dcbf does
resolve it?
