[Solved] Mouse won't work when Laptop runs on battery

Post#1 by surio » 19 Apr 2013, 19:47

Whenever I unplug my laptop from the external power source, my external mouse also stops working.

As I recall, in fedora systems, I go to

/etc/sysconfig/ktune

and uncomment something along the lines of "disable usb power management"

plug the source and unplug once again, and everything works.

Can someone tell me what's the Porteus equivalent?

Many thanks.
surio.

Do, or do not. There is no try.

hi surio,

please edit /etc/laptop-mode/conf.d/usb-autosuspend.conf and either disable this feature completely or blacklist your mouse (follow descriptions).

let us know if that helped as i remember similar issues reported before.
Please add [Solved] to your thread title if the solution was found.

I unplug the mouse, plug it in again, and it works as before! :)
Porteus is proud of the FASTEST KDE ever made.....(take akonadi, nepomuk and soprano out and you will have a decent OS).

@fanthom,
I disabled the feature completely. Now it works. Thanks very much.

@wread
It depends on the computer/laptop model also I think. Older USB chips have this behaviour. :-)
