Sorry I didn't post here again because I coudn't find older kernels where this didn't happen. I poked a bit in acpi and tried with acpi-call and found out that it is really the ec that gets confused and stops to report values. The ec could be reinitialized by adding or removing the kernel module msi_laptop (which will not load by default).
Since I do not use this notebook on battery very often I gave up on this.
But recently I saw that we have newer kernels in the repository. 
The notebook is still on precise and the recent 3.2.0-67 kernel still has this problem but I installed 3.13 linux-generic-lts-trusty some weeks ago and it's fine now.
So this was really a kernel bug that confused the embedded controller and its gone now.

Title:
  ACPI power_supply battery errors to: No such device

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  On 11.10 a few minutes after reboot on this notebook the battery
  symbol in the panel turns to no battery available, normal values in
  the sys interface turn to 'No such device' messages and 'voltage_now'
  gives a wrong number.

  Here is a recent thread
  http://ubuntuforums.org/showthread.php?t=1865832
  and 'BAT1/current_now' gives 'No such device' on post #7
