 ====Real Time Clock (RTC)====
 This one can be hard to spot, and many motherboards don't have one of these. This device, if present, maintains the system time. It has a built in battery, so pry it off and put it with the other batteries for later sorting.

 [http://media.maxim-ic.com/images/appnotes/503/timekeeping.jpg Here's a clearer picture of an RTC.]
 ====Other====
 There are other batteries you'll encounter too. Here are two examples. First, some older motherboards have Ni-Cd batteries soldered on. Given the age of devices which included these batteries, they've probably leaked some toxic gunk. Wear gloves. And second, many Mac motherboards include a lithium cell in a case that's soldered onto the board.

 Slot procs are much larger than socket procs (approx 5" x 2") and are mounted vertically on the motherboard.  The processor itself generally looks like a small rectangular circuit board.  On the motherboard, you'll recognize it as the big vertical thing sticking up almost 3 inches.  The processor will be encased in black plastic and have a heatsink/fan attached to it.
-*Newer Slot Procs - have tabs along the top edge that slide towards the middle of the CPU to release them.  Look for an additional plastic bracket holding the heatsink to the motherboard.  Pry off the plastic bracket, then rock the CPU assembly as you lift it away from the motherboard.

 *Older Slot Procs - are much simpler.  Just pull one of the vertical brackets to the side as you lift the CPU assembly off the board with a side-to-side rocking motion.

 ====Socket Procs====
 Socket procs are square and mount flat to the motherboard.  They are generally about 1.5" x 1.5".  Socket procs (also called ZIFs or Zero Insertion Force CPUs) will have an extruded aluminum heatsink and fan attached to the top of them.  Don't be surprised if the heatsink seems humongous compared to the socket proc itself.

 Pull the processor. This can be tricky, depending on whether you're dealing with a slot-mounted CPU or a socket CPU. Both kinds have a lever or a catch (or two) you have to find and release before they'll come off. Just remember, this is recycling. If you gouge the motherboard, damage a CPU or break a bracket, no one cares. Just don't hurt yourself.
