DOS学习入门 & 精彩文章（教学室） » Why do the optical mouse and keyboard still have power after shutdown??

The motherboard is an EPoX 8RDA+ULTRA, the system is WIN98, and the power supply is a Dafengche 300W. Every time after shutting down, the optical mouse and keyboard (Logitech optical set) still won't lose power. The mouse light stays on, and the keyboard's "Numlock" light also stays on. I don't know why.

This is very normal, because even if it has already been shut down, as long as the host power supply is still connected, the system's peripheral circuits are still working.

You probably set "+5VSB" (standby) on the board......

*The following is quoted from Roy's post at 2003-7-17 12:43:55:* You probably set "+5VSB" (standby) on the board...... Is it in the BIOS??? But I didn't set it. Which item can I change it under?

It's a jumper setting on the board.......

There is an option in the BIOS called USB POWER, just turn it off!

They're both right. It's different for different motherboards. Why not just try it and see! Anyway, when I ran into this problem before, that's how I solved it!

Older motherboards use jumpers on the motherboard, newer boards use BIOS software settings, the purpose is to make things more convenient for everyone.

*The following is quoted from 沈洁's post at 2003-7-17 14:15:04:* There is an option in the BIOS called USB POWER, just turn it off! My BIOS doesn't have a "USB POWER" option. It has these two items: "USB KEYBOARD SURPPORT" and "ENHANCE USB COMPATIBILITY". They're both under "INTERGRATED PERIPHERALS". I don't know which one to set.

I think it's probably power-on by keyboard

I'm a DOS newbie too, and I don't understand what's going on either, so I came to take a look. Didn't expect you to cast a curse I'm dizzy, maybe that method only works for me As for other people~~~~~~~~~~~~~~ who would still dare meddle in "other people's business" next time?
