+I recently bought [ThinkPad
+X220](https://www.laptopmag.com/reviews/laptops/lenovo-thinkpad-x220) just as a
+joke on eBay to test Linux distributions and play around with things and not
+destroy my main machine. Little to my knowledge I felt in love with it.  Man,
+they really made awesome machines back then.
+
+After changing disk that came with it to SSD and installing Ubuntu to test if 
+everything works I noticed that even after a single touch of my external mouse
+the system would wake up from sleep even though the lid was shut down.
+
+I wouldn't even noticed it if laptop didn't have [LED
+sleep indicator](https://support.lenovo.com/lk/en/solutions/~/media/Images/ContentImages/p/pd025386_x1_status_03.ashx?w=426&h=262).
+I already had a bad experience with Linux and it's power management. I had a
+[Dell Inspiron 7537](https://www.pcmag.com/reviews/dell-inspiron-15-7537) laptop
+with a touchscreen and while traveling it decided to wake up and started cooking
+in my backpack to the point that the digitizer responsible for touch actually
+glue off and the whole screen got wrecked. So, I am a bit touchy about this.
+
+I went on solution hunting and to my surprise there is no easy way to disable
+specific devices to perform wake up. Why is this not under the power management 
+tab in setting is really strange.
+
+After googling for a solution I found [this nice article describing the
+solution](https://codetrips.com/2020/03/18/ubuntu-disable-mouse-wake-from-suspend/)
+that worked for me. The only problem with this solution was that he added his
+solution to `.bashrc` and this triggers `sudo` that asks for a password each
+time new terminal is opened, which get annoying quickly since I open a lot of
+terminals all the time.
+
+I followed his instructions and got to solution `sudo sh -c "echo 'disabled' >
+/sys/bus/usb/devices/2-1.1/power/wakeup"`.
+
+I created a system service file `sudo nano
+/etc/systemd/system/disable-mouse-wakeup.service` and removed `sudo` and
+replaced `sh` with `/usr/bin/sh` and pasted all that in `ExecStart`.
+
+```ini
+[Unit]
+Description=Disables wakeup on mouse event
+After=network.target
+StartLimitIntervalSec=0
+
+[Service]
+Type=simple
+Restart=always
+RestartSec=1
+User=root
+ExecStart=/usr/bin/sh -c "echo 'disabled' > /sys/bus/usb/devices/2-1.1/power/wakeup"
+
+[Install]
+WantedBy=multi-user.target
+```
+
+After that I enabled, started and checked status of service.
+
+```sh
+sudo systemctl enable disable-mouse-wakeup.service
+sudo systemctl start disable-mouse-wakeup.service
+sudo systemctl status disable-mouse-wakeup.service
+```
+
+This will permanently disable that device from wakeing up you computer on boot.
+If you have many devices you would like to surpress from waking up your machine
+I would create a shell script and call that instead of direclty doing it in
+service file.
