Hi All,
           Just purchased a wireless rechargable mouse & keyboard. When the
pc powers down the USB outlets power down as well , hence the mouse won't
recharge overnight.How can the USB's be left active with the pc shut down
for the night? I've tried to hibernate but this doesn't work.
I've a Soltek SL-NV 400-64 motherboard and in the manual there is a mention
of HDD Power Down.

Many thanks.

        With some boards, you can set a jumper to power the USB ports off of
the standby power, not the main power.

        THAT said - you sure there isn't a wall wart with that device?  All
the wireless sets I've seen had one, so that you COULD recharge the mouse
with the computer off ...

In your BIOS see if there's a Wake on Keyboard option in Power
Management and a Legacy Support option in the USB section.


I'm so grateful to the USA for their contribution to the war on terror.
After all, if they hadn't funded the IRA for 30 years, we wouldn't know
what terror was.

Check for a jumper between the ATX 20-pin connector and the
rear USB ports.  If you're trying to use a front-panel pin
header, check for the jumper somewere near that header.
Typically such a jumper is on 2 of 3 pins, and needs to be
moved from one position to the other.  Just be sure you have
the right jumper- it should be in the manual.

On my systems it is a matter of going into my computer > properties >

picking the one I want to adjust. Then I select "power management" and
tell the OS whether I want that port turned off to save power when the
computer goes into power-down. You can get in through my computer >
manage also but force of habit still has me doing it the old way...

If none of the other suggestions fix things for you I would offer another

Get one of those cheap "externally" powered USB hubs and plug it into your
computer and then plug your keyboard/mouse into the hub.  As long as the hub
gets it's power from the external transformer it should provide the 5 volts
needed to recharge your stuff.
