PC not totally turned off

Modern motherboards have power going to them all the time, albeit a very low amount.
Some USB ports also have a power passthrough feature so that you can charge devices/power devices when the system is turned off. You could try plugging your mouse into a different USB port.
The days where you could totally power a desktop down went with the demise of the physical power button and the Windows 95-era "It is now safe to turn your computer off" message.

I think many motherboards have lights on them that stay on when its connected to the power - the PC is turned off, but the motherboard still has power to it (bit like the standby light on the TV I guess).
Some USB ports stay powered when the machine is turned off - dependent on the motherboard (so you can still charge stuff from them etc), I'm guessing the one you have your mouse plugged into is one that is still powered.
Only way to really stop any power is by turning it off at the plug.

To be honest, unless the light is really annoying (in which case you could just cover it up), or you don't want to use the power needed to light an LED, it can just be left as is.
I know mine takes longer to boot if I've actually turned it off at the switch (I suspect it's doing extra checks and stuff but don't actually know)
I think time taken to boot may be linked to 'fast start up' as I have this disabled as it grinds my system to a standstill.
If you do have 'fast start up' turned on, (which it normally is by default) then turning the power off via back of PC or plug may well cause it to take longer to boot as assume the 'shut down' hibernation of sorts is cancelled so it boots fully every time you turn it back on.
Guess it all just depends how annoying the lights are to you.

There are a number of ACPI system power states that dictate when a PC is on or off and exactly how 'off' it is. The following might help...
Which ACPI power states are used depends on several things including, power option settings, fast startup, hibernation, etc.
They are really designed to improve booting times and enable other features like wake on LAN etc.
What the OP describes sounds like normal operation to me and unless saving a couple of pennies on your electricity bill is important I would leave well alone.
