On my G4 Titanium PB (867 Mhz DVI), my trackpad works consistently well when the laptop is active, with no problems at all with performance. But, after recent repairs I was testing the latch on the PB and noticed that when I reopened the PB and woke it from sleep, the cursor was locked in place and for roughly a minute, maybe a little less, there was no response from the pad or the button. I'm not too worried, as I rarely put it fully to sleep, but I was just wondering if it's something I can fix relatively easily.
Also, I know for certain that I need to replace the PRAM battery in it, but before I open the unit up and start pulling out the optical drive to get to it, do I really have to replace the entire unit, or is there a simple lithium disc battery that can be replaced alone?
