Check to see if the battery is eligible for replacement under the Apple program. I had that same laptop (purchased in March 2003) and my battery was replaced.playm0de said:My friend is selling his 12 inch powerbook...867 mhz, 640 ram, 40 gig harddrive, OSX 10.4.8 on it for $400. He says it is in good condition and comes with a sleeve. Battery only lasts 30 minutes...do you guys think I should buy it?
