optical mouse
I have 2 computers running win XP home. Both units have a Logitech optical
wheel mouse installed. On one pc the mouse light goes off when the pc is turned off and on the other pc it stays on . I tried a different mouse and the light still stays on. Both units have the logitech software installed and ACPI enabled. Any ideas ? |

I would guess that both the mother boards, and or the USB boards (if using a
slot USB board) must be different. When you have an ATX power supply, there is always some voltages on the mother board. This is to maintain the CPU to respond to the wakeup or the turn on command. The port that the mouse is on, is having some voltage outputting on it when the computer is off. I have seen this with USB, and serial ports on some machines. -- Jerry G. ========================== "xiaoke" wrote in message news:egkMc.98137$Mr4.76666@pd7tw1no...

Thanks for your reply. Both mice are on PS2 port.
Is there any fix for this? "Jerry G." wrote in message ... I would guess that both the mother boards, and or the USB boards (if using a slot USB board) must be different.

There should be a jumper on your motherboard that controls this feature, look in the manual for a 5V/5VSB jumper or wake on USB or wake on keyboard/mouse. Typically the jumper is within a couple cm of the port or pin-header effected. Set to 5V to turn off device, 5VSB to keep it on. If your only concern is that one stays on, it's not a problem, no need to change it unless you want to enable or disable the power-on feature for whole system turn on. |

I dont think I want to mess around with the whole system settings. Maybe some wrap around tape on the mouse will do the trick I think wake on keyboard/mouse is disabled in the bios. Once again thanks for your input ! |

If you don't need that feature you might as well change the jumper, as it is causing all USB devices to run from a much weaker part of the power supply, and this part is not being cooled when system is off. It may not be a problem but is a waste of power and would seem a better alternative than tape. Although, if you really want to just block the light from coming out of the mouse a better approach might be disassembling mouse and spray-painting the inside... just be sure to remove the optical lens assembly too if it's attached to the bottom. Some mice also have a 2nd LED with the sole purpose of lighting up the mouse (at least one microsoft model comes to mind). If you desoldered that LED (or just snipped it off with scissors) that would also reduce light from mouse, though not completely eliminate it. |

Both units have the logitech software installed and ACPI enabled. Any ideas ? Try this. Goto Device Manager Mice & other pointing devices. Select the mouse and right-click for Properties. Look on the Power Management tab. Is there a check-box labelled 'Allow the computer to turn off this device to save power'? This option exists on my pc but may be dependent on the mouse driver installed. Martin. |

The bios doesnt have any options either. The only jumpers on the board are for surround sound and cmos battery. Thanks for your help. I guess I'll have to put up with it. |
