Interesting, I noticed a new symptom during last few days. No, the battery is still the same, dead. What now happens, is that my laptop hibernates itself sometime during the day, even though the AC is plugged in. And there has not been any breaks in the electricity service, as my other computers which are not laptops, keep running day after day and all none of the other electronics in my home indicate any symptoms of electricity breaks.
So, basically, when I come home, I find my N100 hibernated, has happened already some three or four times. And my power settings are not set to hibernate ever if powered by AC.
