Linux doesn't seem to know battery status

myname · 2011-10-17 12:29:14

I have a sony vaio vgn-p11z. The first thing I mentioned was the broken status display of notion after an update, but this wasn't that bad.
acpitool says there is no battery present, acpi however displays valid data about battery 0.
The thing that really got me was linux making a filesystem check during boot while on battery.
Any ideas on how to fix this?
Thanks in advance.

This also apears with a IBM T40. My current linux-ck kernel still enables acpi to read the battery state, but with common core linux kernels it doesn't work anymore.

I believe acpitool uses /proc which is obsolete in the 3.x kernel series, whereas acpi uses... something else I can't remember. sysfs?

Not sure why your system is doing filesystem checks while on battery though, unless the filesystems were not cleanly unmounted previously. Is that a possibility?

Nope, it was a regular check (mounted xx times)

Anyway, I cannot read out my battery state. Would be nice to know when I have to hurry up saving things. Will I have to patch acpi, or is this solved soon ?
