Hey guys! I'm having some more issues with my cousin's iBook I'm trying to fix. First of all, it's running on Panther (10.3.9) So here are both my problems: - Here and there, the laptop makes this loud buzzing noise... it's like you are holding down the enter key somewhere you can't enter anything. It's not a GSM buzz or anything, but I don't know how to get rid of it. I've tried doing a couple of things, but it hasn't worked. Any ideas? - Secondly, I'm having some trouble with the mouse often. (I unchecked ignore accidental trackpad click). For example, sometimes the mouse will disappear and start to lag. Also, if we're on Safari or on another application that has something to do with scrolling, it will start to scroll down and you can't scroll or move anything back up. I have no clue what's going on here. Any help is greatly appreciated. Thanks!
