Yes, that is normal. The reason is because most recent ATX motherboards
(such as my A7N8X Deluxe) have a "Power On By PS/2 Mouse" function. In
order for that function to work, constant power must be maintained to the
mouse, even when the computer is powered down.

I have all my peripherals plugged into a surge protector. When I turn off
the surge protector, the optical mouse light goes off.

Yes and no, this depends on your motherboard, my old Soyo board also
keep the caps lock LED lit.

On most modem boards, there is still power going though the board, so it
can be started up via a keyboard or mouse.
I can press a key on my to start it up.

While it is normal you can still disable it if...
1. It's connected to a USB port and
2. You don't need to use the USB wakeup function for that port and
3. Your motherboard has a jumper to disable the USB wakeup function.

Question: Will the mouse-wakeup function work only if attached to USB? I
have my trackball on PS2 and it won't wake the computer, even with the
function enabled in bios.

Depends on the MOtherboard, my latest the Asus A7N8X clearly states that
this service is dependent on the PSU being capable of providing 2A on the
5v circuit. I have no idea if mine does (It is one of the Ultra Quiet ones
from QuietPC.com) and to tell the truth have no tried it but have a look at
your MB manual.
