    Lightbulb [SOLVED] bluetooth keyboard + mouse loosing connection

    Hi all,
    I was having problems with my Bluetooth keyboard and mouse.. loosing the connection all the time.
    So, after some investigation.. error logs and so on.. I was able to fix it!
    Never failed again. Posting here the solution in case someone else is having problems.

    My hardware specs:
    - Sony Vaio PRO13 laptop
    - Dell Premier Wireless Keyboard and Mouse - KM717

    Steps to fix it:
    1) edit this file: /etc/default/tlp (more info here: )
    2) search for
    3) uncomment it and set the value to 1 (this means that whatever happens in terms of power management of the laptop, the bluetooth devices won't be turned off/suspended)
    like this:
    # Bluetooth devices are excluded from USB autosuspend:
    # 0=do not exclude, 1=exclude.

    4) reboot the laptop (or should be enough to restart the tlp service:
    # tlp start )

    That's it! Keyboard and mouse never failed again regardless of the laptop battery level.

    FYI, in the most recent releases (15.2, Thunderbird et al.) the file /etc/default/tlp is now /etc/tlp.conf
