In the past I was annoyed by the system notification about “mouse battery low” to the point that I just changed a still-good battery to get over it.

This time I decided to tackle it once and for good.

I found this post https://wrgms.com/disable-mouse-battery-low-spam-notification/. All the credit go to the author

Please go there for more detail, this is just my self note.

1. Download and patch upowerd

# Download and patch upowerd
#
git clone https://gitlab.freedesktop.org/upower/upower  
cd upower/src  
wget https://gist.githubusercontent.com/guiambros/f2bf07f1cc085f8f0b0a9e04c0a767b4/raw/ef90dfcfa2489bab577bd984a6082abacdf8b0b1/up-device.patch  
patch < up-device.patch  
cd ..  
./autogen.sh
./configure
make

Ater the make command, you will have these two new file

# cd src/.libs
upowerd

and

# cd tools/.libs  
upower  

Next we will back up the originals and replace them with these instead.

2. You need to know the path to upower

upowerd path

/usr/lib/upower

upower path

/usr/bin

3. Replace the originals with new patched file

3.1 Replace upowerd

# Install upowerd
# From the original folder
PATH_UPOWERD=”/usr/lib/upower”
cd src/.libs  
strip upowerd  
sudo chown root.root upowerd  
sudo cp upowerd ${PATH_UPOWERD}/upowerd-silent  
cd ${PATH_UPOWERD}  
sudo mv upowerd upowerd-original  
sudo ln -s upowerd-silent upowerd 

Install upower

From the original folder

PATH_UPOWERD=”/usr/lib/upower”
cd tools/.libs
strip upower
sudo chown root.root upower
sudo mv upower ${PATH_UPOWER}/upower-silent
cd ${PATH_UPOWER}
sudo cp upower upower-original
sudo ln -s upower-silent upower

# Restart upowerd
#
sudo systemctl restart upower
