Is it safe for keyboard lights to be always on?
Im currently using Lenovo 720S , 13 inch.
its my first time to use an ultrabook. anyhow ive used laptops before with backlit keyboard that you can customize to turn it off 30-second to 360 seconds if not being used or simply idle depending on your settings.
now the funny thing is that the keyboard lights of my laptop can't be customized or simply just stay always on all the time even if im idle though you can certainly turn it off manually.
my question though is that is it safe or okay to keep the keyboard lights on as I leave my laptop always on 24/7 as my work always involve with emails?
or should i turn it off manually as i go to bed? (fn+spacebar)
Is this a good question?
