Lost wireless mouse connection when laptop is on battery

rated 0 times [ 4] [ 0] / answers: 1 / hits: 3143 / 1 Year ago, mon, january 30, 2023, 5:42:42

I just bought a HP wireless mouse, but I'm having some issues.

The cursor frequently becomes non-responsive to mouse movements. I noticed that it only happens on my laptop when it is running off the battery and whenever the mouse isn't moved for say 20-30 seconds, I then have to touch the laptops touch-pad to get the mouse to reconnect.

So it looks like it maybe power-management is interfering but I'm not really sure how to troubleshoot this.

Edit : An important piece of info which I completely forgot mention is that I didn't have this problem with my previous Sweex MI420 wireless mouse .

$ dmesg |grep -i mouse:

I fixed the problem by changing a setting in /etc/laptop-mode/conf.d/usb-autosuspend.conf

According to a comment in the config file, some USB devices don't correctly support autosuspend.

Theres an option in the config AUTOSUSPEND_USBID_BLACKLISTto add a list of USB device IDs for offending devices , I added the ID for the mouse and now it works without issues.

#

# Configuration file for Laptop Mode Tools module usb-autosuspend.

#

# For more information, consult the laptop-mode.conf(8) manual page.

###############################################################################

# USB autosuspend settings

# ------------------------

#

# If you enable this setting, laptop mode tools will automatically enable the

# USB autosuspend feature for all devices.

#

# NOTE: Some USB devices claim they support autosuspend, but implement it in a

# broken way. This can mean keyboards losing keypresses, or optical mice turning

# their LED completely off. If you have a device that misbehaves, add its USB ID

# to the blacklist below and complain to your hardware vendor.
