laptop-mode-tools installs udev rules at /lib/udev/rules.d/99-laptop-mode.rules that restarts lmt when you plug/unplug your laptop or a usb device. It's how it determines whether to enable or disable laptop-mode when the power supply changes or set autosuspend on usb devices. lmt also runs the script /lib/udev/lmt-udev every 150 seconds through the systemd timer /lib/systemd/system/laptop-mode.timer to detect battery changes. This script reloads/restarts the systemd service. You may stop this timer, but lmt will still be restarted when you plug in your laptop or a usb device. Stopping laptop-mode.service and masking it through 'systemctl mask laptop-mode.service' might stop lmt, but I'm not 100% sure, and I haven't tested it. If it does work, you would need to unmask it (systemctl unmask ...) in order to be able to enable it again.
