Pretty much. I had an issue with post-shutdown powering of Human Interface Devices (keyboard and mouse) like you are and after I set the jumper to the 1-2 position the devices no longer received power after shutdown.
I'm looking at the manual for your motherboard and no such circuit exists on it. But there is a setting in BIOS that I think you may be missing.
Restart and go into BIOS and go to "Power Management Setup".
Two values labeled "Power On By Mouse" and "Power On By Keyboard" should both be disabled, either of them being enabled will allow them to be fed power after you shut down to both PS/2 and USB Human Interface Devices, thus causing your issue. Please check that and confirm both are disabled, they may be disabled by default, but it's best to check.
Hi, I am aware of that too. Its called ErP Support. If i enable this there will be no more power fed to the PS/2 and usb port(Power On By Mouse" and "Power On By Keyboard" are both disabled.) However if i turn off the main switch and on again, the mouse light up again even though i did not turn on the computer.
When i tried using a Usb cable mouse, theres no more light.
Best to double check the settings I listed. If not, then best I can label it down to is that your Motherboard has a defective transistor that won't disable power feeding to the PS/2 ports. We've gone through any and every possible thing that can cause the issue but we still get nowhere. Sorry man.
The transistor and associated circuitry costs more to install and implement than one little jumper. It would appear its a lot more reliable too.
It would cost more only if the transistor was discrete. It's not. More reliable method, that costs significantly less, is the transistor. Any motherboard using jumpers in the past ten years would be archaic.
OP seeks an option that disconnects his mouse from an 'always on' power supply. Most often set in the BIOS. And stored in CMOS.
Of course, numerous other (rare) problems can exist. For example, the motherboard could have a solder splash or a 'not completely isolated' PC trace. Inspection would easily find that unlikely possibility. Fixing the solder splash is trivial. A PC trace problem - not so easy. Bottom line - the 'always on' power supply is connected to PS/2 ports. The OP does not want that.
i may have missed a post in this thread ,so bare with me,
i note you said when you plugged a wired mouse in the mouse lights went off, this leads me to think you have a wireless mouse, if this is correct then doesnt the mouse have an actual off/on switch,
turning the mouse off by a switch seems a bit obvious though,
just had to ask .
Hi GradeAbra
Sorry for not reading all 5 pages threads. If you go to this Spec in Gigabyte site you'll read the red printed this below quote.
It means your board has features including support for on off charge (via front panel USB whether your PC is on the state of on, sleep, even when it is off). Much clearer explanation can be found here in this Gigabyte siteUnique Features
- Auto Green
- Smart Recovery
- Support for Q-Share
- Xpress™ BIOS Rescue
- @BIOS™
- Supports EasyTune
- Xpress™ Recovery 2
- Xpress™ Install
- Download Center
- Q-Flash™
- Support for On/Off Charge
- Support for Easy Energy Saver
It is very useful for charging your gadget in a way that it functions as quick charge (faster then normal charger).
This feature is now available with many PC and laptop, but for laptop mostly there is option to turn it off. (found it available on my Samsung netbook and Fujitsu notebook)
I don't have any idea about how to turn it off on the desktop version. But since it is a features said as On/Off charge, then you may just leave it as it is.
hope that help a little.
