We strongly recommend that you leave the computer on at all times, 24 hours a day, 7 days a week.

If you are here, it's probably because you have a blue screen with an HDMI 1 no signal message. It means that Lü's computer is turned off.


Here are steps you can use to turn the computer back on :


  1. Lü 2nd generation : press the space key on your keyboard repeatedly for 5-10 seconds until you see the Dell logo appear.


  1. Manually press the computer's power button on the computer. A lift or a ladder will be required. 


  1. *Turn off the breaker(s) of the Lü's system for 2 minutes. The computer will reboot automatically when turning back on the breaker(s).
