PS/2 Mouse Keeps Working After Shutdown

[TheSmallCreeper]

Hello Fellow Tom's Hardware Users!!!

The last few days I have been testing my old Microsoft WMO mouse. USB connection works great,but when I connected it through PS/2 (using USB to PS/2 adapter) it works but everytime I shut down my computer, mouse keeps working, drawing power from PS/2 port and emitting a annoying red light. How can I prevent my computer from "giving" power to PS/2 after shutdown?

My modo: AsRock 970 Pro3 r2.0 (using the latest P1.80 BIOS update)
My OS: Windows 8.1 64-bit (Ultimate Edition)

Thank you in advance and please don't get out of the topic!!!

PS: I have tried Disabling "On/Off Play Setting" in South bridge under Advanced Settings in the BIOS and disabling any Wake Up from Keyboard-Mouse function through BIOS and Device Manager

The reason why I am using PS/2 instead of USB is that you can only increase USB polling rate up to 125hz on Windows 8 (even if on Windows 7 you could "overclock" your USB port up to 1kHz), while maximum rate of legacy PS/2 is 200hz.... just trying to see any difference

A very common issue which I wouldn't class as a problem as such.
It's actually been like that for years, but is only noticed since they started putting fancy lights on optical mice.

If your PSU has a rocker-switch, just switch that to "Off" position after shutdown, or switch off at wall socket.

Mine's same but it doesn't bother me at all.

Or get a native PS/2 mouse from Amazon which has no fancy lights on it.

I don't think that switching On/Off my computer every time I want to use it is the best idea....

Okay, buy a mouse with no lights on top then.

I turn my computer off when not in use for years ? if that does some kind of harm then you got something wrong with it . with turning it off normally the computer still has ''stand by '' power as long as the psu is not switched off thus why your mouse seems to still be under power

you have to turn off the psu to discharge the board -- running something 24-7 is just a waste when its not in any use or reason - I don't even use the sleep [all opinion]

p.s --check if in the bios if something like wake on device option is on that may affect that ???

The PS/2 interface doesn't poll devices like USB btw.

This is intended behavior. Some ASRock boards have a jumper to disable the PS2 power after shutdown. It appears yours does not.

Your only option is to use a USB port.

Check the mouse properties in Windows' Device Manager to see if the Power Management allows the computer to turn off the mouse to save power.

Well as I previously mentioned I have disabled Wake Up options from BIOS , however in Windows Device Manager does not allows me to enable the option that turns off mouse to save Power, I mean that "check-box" is grey

Have you tried the registry fix for the polling rate limit problem?

 

[junkeymonkey]

maybe a windows 8.1 thing ?? anyway tried this ??

Original PS/2 connectors were black or had the same color as the connecting cable (mainly white). Later the PC 97 standard introduced a color code: the keyboard port, and the plugs on compliant keyboards, were purple; mouse ports and plugs were green. (Some vendors initially used a different color code; Logitech used the color orange for the keyboard connector for a short period, but soon switched to purple.) Today this code is still used on most PCs. The pinouts of the connectors are the same, but most computers will not recognize devices connected to the wrong port.

Purple Keyboard
Green Mouse

so maybe the green give a better result ??

What do mean??? I have increased PS/2 polling rate through registry up to 200hz... I wasnt able to increase USB polling rate using some custom USB drivers found at overclock.net since they dont work on Windows 8 so I switched to PS/2 to give a try... I have also installed Microsoft patch Kb2908279 but didnt helped

EDIT: What does purple and green PS/2 have to do with my problem ?? My mouse works perfectly using PS/2 port but it doesnt turn off when I shut down my computer

But this fix is only for those who have a last-gen gaming mouse... This fix doesn't work for me since I cannot increase polling rate through custom usb drivers..
