Welcome to the HP forum!
Thank you for your inquiry, I will do my best to help.
I understand you would like to turn off the backlight and the wireless light. Here is the HP Getting Started Guide. Please note page 13, items 3 and 4. Item 3 the backlight can be turned off. The wireless however cannot, as it is a indicator of your wireless status. If you turn the wireless off, it will become an amber or orange color to denote that you are not connected. I hope this helps.
