It seems that I didnt't started my PowerBook G4 for more than two week!
The battery was on 84% (not bat for the cheap replacement battery, I
think) but the RSS reader shows tens of unread articles..
I use this machine just for weekend browsing and (not so often) for
testing of portability my software codes. I think I am able to use this
machine (the last version of 15" PowerBook G4) as a main laptop if
necessary but I have only one and it's not in the best condition (it
was heavily used by its previous owner). So I keep it at home.
And I should finally fix the RTC battery in my SGI O2 and return it to
use, too...
