If you have any issues to suspend your laptop e.g. suspend command doesn't work on your laptop, try changing the default sleep module to uswsusp:

  1. Edit /etc/pm/config.d/module and add the following line:
    SLEEP_MODULE=uswsusp

  2. Edit /etc/pm/config.d/defaults and add the following line:
    S2RAM_OPTS="-f"

  3. Reboot and try to let her sleep.
