i have had my 14" iBook G4 since 2005. the battery has been shot for a couple months, but it usually works when i keep it plugged in. however, sometimes it likes to randomly shut down without warning. at one point, it gave me some sort of system failure message on the display. then it went into sleep mode and started making strange beeping noises that i had never heard before. i took it to the genius bar, and the guy was not very helpful. he said that the logic pro/port (??) needs replacing and that it would cost $500, plus i need a new battery which would cost $130, AND i need a new power adapter. he said i'm better off buying a macbook pro since i can get the student discount. i've already ordered the macbook pro for myself, but i want to fix up the iBook for my mom. i don't plan on replacing the logic port thingy, however, i would be willing to invest in a new battery. i've been looking around on amazon and i've found these two options: http://www.amazon.com/LAPTOP-BATTERY-APPLE-M8416G-M8416J/dp/B000PB4D3E/ref=cm_cr_pr_product_top and http://www.amazon.com/Notebook-Batt...4?ie=UTF8&s=electronics&qid=1280751150&sr=8-4 since the second one is sold by apple, i feel like i should trust that more. although the first battery received many positive reviews. which one is the better buy? and is it smart to go refurbished on the apple battery to get it around $20? thanks for any help!
