I guess this must be a dumb question because the Apple page for the battery recall doesn't say anything about this, but is there anything I should be worried about when I remove the battery? I haven't flipped over my Powerbook yet to see actually how to do this but I assume it must be incredibly easy if there are no instructions.

Step 1. Find a Nickel
Step 2. Flip the powerbook over
Step 3. Put nickel in slot
Step 4. Turn 90˚

Depends on the PowerBook. For my 17 (and I'd assume a 15 since you can hot swop batteries while the PB is in sleep mode), I just push the two switches to the side and it pops out. Put a new battery in and it just pops in.

The 12 and 15" AlBooks use the coin slot latch. It's still hot-swappable in both of those when on AC, and sleep-swappable on the 15.

Just wondering about the hot swapping in sleep-mode: Does it have some sort of short-time backup battery built-in or do you mean you can swap out the battery only while connected to AC?

I just had the chance to take out my battery on my 12" to check it against the recall. I had a bit of difficulty getting it back in.
As for hot-swapping, I assume the larger power books have room for a capacitor (as did older Powerbooks) to swap the battery in the field—without AC power. For all the portables, you can swap the battery while on AC power—sleeping or not.

Yes. They have a backup battery that maintains the contents of memory for the short time during the sleep swap. Obviously, the more, higher capacity memory you have, the shorter the swap time will be because more memory uses more power. So if you have 2 GB of memory, swap that battery quickly.

Although you should be able to get at least a couple minutes' sleep time from the backup battery, even if you have 2GB of RAM. I would not encourage dilly-dally while swapping your battery but it is hard for me to imagine a situation where swapping the battery is longer than 2 minutes!

All PowerBook G3 and older PowerBook models, and all 15 and 17" PowerBook G4 models have a small lithium-ion (NiCad in really old models) backup battery -- not a capacitor -- that allows them to stay in sleep mode for 5-10 minutes with no AC or main battery. The 12" PowerBooks and all iBooks do not have this backup battery and must either be on AC or shut down to swap the battery.

PB100 used 2 watch batteries and would hold memory for up to 1 hour!
