Keep your laptop home screen clean and uncluttered. Organise your folders such that you do not have scores of icons spread across the screen.

    Use a relatively neutral picture for the desktop and disable the screen saver.

    Sign out of any social media networks for the duration of the presentation or set your status as unavailable or busy.

    Open your presentation and set it in slide show mode before you connect the laptop to the projector.

    If you have links to videos or images that are not embedded in the presentation, keep those open and minimised, ready to play at the appropriate point.
