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. -- cgit v1.2.3
