One thing i don't understanding is how come my keyboard is not light up after my comp is shutdown like the mouse? My keyboard is a PS/2 keyboard too.
You don't see the need to call them? 7 pages of people unsuccessfully guessing at a problem that Gigabyte could tell you how to fix in a 10-15 minute phone call and you don't see any need to call them. I feel like we're on candid camera or something.

Kevin Ismail's reference to On/Off Charge support refers to a specific set of USB pins on the motherboard that provide power to charge devices when the system is off. It doesn't apply to the PS/2 port. In looking at that, I did come across something that might address the issue. However, I can't really find a reason at this point to continue offering help to someone at this point who refuses to help us in return by saving us some time and effort and just calling the manufacturer directly. That's pretty selfish to prefer to have others scramble and waste time grasping at straws rather than put out any effort yourself.

I will stay tuned, however, to see how many times OP will re-ask the same question and others will re-answer it. It's like having our own Groundhog Day thread on here.

Sorry for not catching up with the main problem that was PS2 mouse lights on.
Forgot to ask whether the mouse is USB type connected to PS2 port using USB to PS2 adapter or plain PS2 mouse.

What come to my thought is that the factory might have deliberately done that. To my knowledge, PS2 ports are powered from the same source as USB ports (5 volts) that is why USB mouse/keyboard can be plug to it using adapter. IT is possible that the factory board schematic was well arranged, but since board electronic switch using thyristor component (TRIAC or DIAC) it could probably the feed to thyristor gate was improper or fail to trigger and leave the switch unchanged.

It happened to my UD2H board in the past until it worn out last year.

Well then. Though had gone through 8 pages scramble haven't helped, but still, I call it giving help.

That was explained previous. Computer has two completely different 5 volt power sources. These were described as 'always on' and the PSU. BIOS may select which powers that mouse. If the mouse is lit when computer is powered off, then the 'always on' 5 volt supply (another correctly called it +5VSB) would be powering the mouse.

OP is doing what the better informed do. Ask not only to fix the problem. But learn why a problem exists. Too many 'computer experts' never do that. They would rather call tech support to fix a problem and learn nothing. Explains why so many 'computer experts' do not know about the power controller, an 'always on' (or 5VSB) supply, and other relevant questions asked by the OP.

So, why is the mouse constanly powered by the 'always on' supply rather than the 5 volts from what was called the PSU? That remains a still unknown answer.

Triac or diac is irrelevant here. If a triac is providing DC power, then the triac never powers off. Clearly triacs, diacs, thyristors, etc are irrelvant and not implemented here. Only confuses things.

Spending a week and 73 post trying to fix a problem that isn't a problem doesn't seam all that wise to me. I'm no computer expert.

Display getting slower to light after mouse or keyboard activity
I searched for similar cases, but all results involved resuming from sleep or standby. In my case, the power options are set to "never sleep" and "turn off the display" after 2 hours (I changed it to never turn off until this is resolved). When it first started it was a few seconds....
