After using it for several weeks, I noticed that my PowerBook’s battery capacity has decreased sllightly. Where it used to be able to run for about 2 hours and 15 minutes after a full charge, now it rarely able to stay on for 2 hours.
I’ve been guilty of running it for hours while plugging it to the power socket though.
Then I thought, let’s see if this thing can run without battery, just like my previous laptop (Lifebook). So I rebooted, then while it’s on the logon screen, I turned the battery lock *plop* there goes the battery, and the laptop is still running happily.
I’ll still buy a spare battery later, but now I’m no longer in any rush. Very nice.
