I have an NS 1250, which while several years old, was working fine even after I upgraded to W 7. Then a few months back, with a power interruption it would go into power save and I would have restart as a resume. Same with self-test.
Battery life was indicated as good, but since the batteries were older than three, I bought new replacements. Same problem: self-test leads to shut down and need to resume.
I uninstalled the Powerchute program, with difficulty, and reinstalled version 2. Same problem: run self-test and it puts machine into power save.
