We are a community of HP enthusiasts dedicated to supporting HP devices and technology. If they are available, they can enable the backlight by pressing Fn and F4 keys (Fn+F4) at the same time. Thank you for participating in the HP Community Forum. Please check the F3 and F4 keys on your ASUS Notebook keyboard to see if you can find the 'backlight keyboard symbols' on the keys. If the feature is something that HP (as a company) wants to change, no doubt we will see that in future models. (Warning) For keyboards that do not support Per-Key RGB, please check the. After around 5 seconds, there is no turning back. If the keyboard LED backlight could work, but the color display is abnormal. Sometimes I manage to turn the lights on, but this is only possible in the first 5 seconds after Windows started up (and thus the first seconds I can see my desktop). The answer is: HP backlit keyboard does not light the space bar. The function to activate the backlights of my keyboard doesn't work as it should. I wonder how many send their laptops in thinking their keyboard is defective only to get it back with the same result? Even technical support seemed to think it was a problem. Can't figure out how HP could have saved much not lighting one key? If you search the forums as I did, others have asked the same question and nobody at HP seems to be able to correctly answer this.

I just questioned it, because I have owned Dell's and Apple Mac's and all have every key lighted. They light all keys except for spacebar? I certainly question why they do not light the spacebar? But its obviously by design not a flaw. Yes, I guess this is what HP keyboards do.
