I have been using my PowerBook 150 A little more and I think I'm killing the battery charge. I have to plug it in for a second to get it to start (The pram battery is dead) and I sometimes plug it in when the charge is around 50% (Sometimes more). By the way the battery is an after-market NI-MH battery which has done me very well so far. I just want to know any tips on keeping this battery alive. I also want to know if I could somehow (Or somewhere) get the pram battery replaced because it is very annoying to have to find a plug to turn it on.
