Thanks for your description how to open the netbook to reset the CMOS
RAM by removing the battery and the report that it solves the issue.

This proves that there is a BIOS bug that
  * writes something like a lock when the switch is turned off.
  * does not release the lock when the switch is turned on again.

Maybe there is a utility which can be used to erase the CMOS RAM using
Linux without the need to open the cover each time when the problem occurs.

I hope that Lenovo will bring out a bootable CDROM image which can be
used to update the BIOS to a newer version where the bug is fixed and
which also has a function to clear the CMOS RAM by overwriting its content.
