My Optical mouse stays lit after I shut down. Im using a Soyo 845PE lite Motherboard.

[DolfanJay]

When I shut down the computer it starts to shut down and the mouse light goes out and then at the last possible
moment before the power goes out the mouse light comes back on and stays on. The only way to get the power
to mouse off is to kill the power on the back of the PSU. Its an Intellimouse 3.0 and I'm using it on my PS2 port. Nothing
else in the computer continues to run after shutdown. I cant figure this out anyone have any ideas or maybe have had
this problem?

the atx spec states that even when the coptuer is "shut down" it still has power. most high end motherboards come with a small LED that is on whenever the mobo has power (including when it is "off"). the only way to completely kill the power is to turn ff the PSU in the back

Thanks Eklass,

You read my question wrong or i didnt make it clear. I mean the light on my optical mouse. I understand the light
on the motherboard itself. To tell you there is still power to the board so you dont try to switch components and short
something out.

Just turn your main surge protector off or the PSU switch off. It's like this for all optical mice. Though the power is off but the there is still power to the mouse connector.

Thanks Bad Dude,

Thats what I've been doing to get the mouse to shut off. Just installed this motherboard and wanted to make sure I didnt have something set up incorrectly. would it shorten the life of the mouse to just leave it lit?

I have same problem too with Epox 8K3A and 8K3A+. My previous MB did not lit the mouse. If you let the mouse lit on, it will shorten the life of the mouse! I just kill the power off everytime!

Just leave it on. The "life" of the mouse will not be shortened in any way. A optical mouse is a solid state device, no moving parts. Its not going to wear out or burn out. The LED light in your mouse is not like the regular incandecent light bulbs we are all used to, it will not burn out or otherwise get dimmer from being left on.

Your keyboard is probably being fed power as well. Modern motherboards do this because most these days have KB/mouse power on features. This allows you to just hit a key on the KB or click the mouse to turn the computer on. To detect keypresses/clicks the device obviously has to be powered up.

It does it on mine too...I actually kinda like it. When I can't sleep in the middle of the night and wanna frag to relax, it helps me find the way...

I have also read, tho have not tried it, that if you use the mouse on a USB port, the light does not stay on? True?

Hi this is the same person as DolfanJay I was updating my profile and now I cant log back in. So i created another account.

Anyways I found something else that stays on when I shut the power off. My onboard NIC I didnt notice it at first and then I saw that the port light on my hub was lit. My keyboard does not stay on though. I've looked over the entire bios and I've disabled everything that relates to STR. There is a listing that I can either pick STR or POS. I have no idea what POS means and the manual doesnt do a very good job explaining it. Not that big of a deal. Thanks for everyones help.

I had this same problem with my Logitech optical mouse when I upgraded to an Abit NF7 board. Plugged the mouse into the USB instead of the ps2 and now the led goes off at shutdown. The only problem is for some reason I can't get Win98 to detect my mouse via USB. I normally use WinXP, but for some apps I need to boot to a Win98 HD, so then I have to switch the mouse back to the ps2 port.

By the way, for my board, I couldn't find any thing in the BIOS that would fix this issue. Someone suggested changing a jumper on the board, but since I don't know what it does I don't want to mess with it.

sorry, that's what i was trying to get at by going over the atx spec stuff. the led is lit and therefore the motherboard has power. additionally, other components have power, such as the ps/2 or usb may

Of course it will shorten the life of the mouse!!!!!

EVERY electronic circuit using power is degraded with time - thats a fact!!

BUT - a LED (as used in a Optical mouse) should have a lifespann of around 100.000 hours, so it takes at least more than 10 YEARS before the led is out - I think the buttons U click on is out WAY before, as the normal lifespann of the buttons is about 10-50.000 clicks. So stop DoubleClicking and assign the wheel as DoubleClicks!!

BTW: Are we still using mices in 10 years time??

No one really knows for certain the life span of the current generation of LEDs. Current estimates are around 20 years if the LED is ran at its max rated voltage/current. Going over the LED's max ratings will shorten its life dramatically. And in a optical mouse the LED will spend quite a bit of its time in low power mode. (notice how the LED dims if you do not move the mouse for a few seconds?) This will increase the life span of the LED by years.

But as Clauzii said, the micro-switches used for the mouse buttons will wear out LONG before the LED is even a quarter of the way through its life span. (The left mouse button on my 2-yr old Logitech optical has already wore out once! I like the mouse so I replaced the switch myself )

 

[Clauzii]

Yes, I fix my things to - unfortunately not everyone knows in which end a soldering iron gets hot

 

[Bad Dude]

Do you really care if it shorten the mouse' life? You would probably upgrade to a better mouse by the time it dies. If you turn the power completely off, then the motherboard will draw the juice off from the battery to keep the settings. Either way you lose. Do the most convenient or most comfortable thing for yourself.
