Hi,

I have the same problem with an Acer Travelmate 4001LCi. What I have
been able to find out so far is, that these laptops feature a 'smart
battery'. For these battery there is currently no driver, but Shaohua
Li from this list considers writing one. I would be very grateful, if
you really do this :).
I tried the driver from ftp://ftp.poupinou.org/acpi/i2c-acpi-ec.c. It
correctly detects the battery, but tells me that there is no module
'smartbatt'. I guess this is the intended behaviour.
If there is something I can do in order to get a driver for my smart
battery (provide information, test drivers, ...), just tell me.

Greets,
Johannes
(also running on a 2.6.9 kernel)
