Thanks for your help so far.

Here's the output from gkrellm (which starts fine with the patch):

I notice the "charge_full = 0" line which appears strange to me.
Perhaps this netbook does not support that feature?

No. The monitor was not even enabled because it always showed 0%
(appearently, the code is still executed). Same for the monitor in XFCE.

ibam says:
,----
| mjw@aegir:~/downloads/gkrellm-2.3.2/src$ ibam
| Total battery time:          2:00:00
| Total charge time:           2:00:00
`----

The only useful information can be obtained via ACPI:

,----
| mjw@aegir:~$ cat /proc/acpi/battery/BAT0/state 
| present:                 yes
| capacity state:          ok
| charging state:          charged
| present rate:            0 mA
| remaining capacity:      4378 mAh
| present voltage:         12473 mV
`----

I tested the battery time with the following script which I started on
the netbook and went to sleep.

,----
| #!/bin/sh
| 
| echo "starting battery test..." > battest.log
| 
| while true; do
|   echo -n "."
|   date >> battest.log
|   cat /proc/acpi/battery/BAT0/state >> battest.log
|   ibam >> battest.log
|   echo >> battest.log
|   sync
|   sleep 300
| done
`----

The other morning, it was off (no surprise) and the logfile read:

<------------- snip --------------->

I just booted Windows XP which has all the proprietary Lenovo drivers
installed. There, the Lenovo tool told me that my battery is currently
96% charged (which seems to be accurate given my previous plug/unplug
experiments unter Linux). So the hardware itself seems to be ok.

Best regards,
