770 + OS 2008He started to reboot after 1 min again

10 times today and over and over again

Swap is not a problem as removing memory card
770 OS 2008He keeps rebooting.

Problem must be with power management,
as if battery is not full, it worked fine

Any idea how to set display, oh not, rebooted again

There must be run some hidden process
starting reboot after 1 min.

How to disable internal timer for 1 min ?
