Re: My FN+F6 doesnt keep my screen on the laptop open
I think you're trying to output the screen to external monitor right ? So when you press Fn+F6 this will output to external monitor only but if you do it again it will output to both (External and you LCD) and if you repeat the step again you're back to normal.

You sure it's not that you just haven't switched over to getting the screen to display on your external monitor, not just on the laptop? It's usually done by pressing the Fn key (bottom-left on keyboard), and a function key (eg F5/F6).
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8
The following applies to Acer Laptops. You did not specify the brand of laptop you had. If your laptop is not Acer, the specific keys mentioned may be different and you should adjust accordingly.
If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on. If pressing any key does not turn the display back on, check the following.... 1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level 2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display 3. Backlight might be turned off. Press Fn and F6 to turn on the backlight. 4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.
Fn + F5 toggles the display output, the trick here to wait each time you hit this combination because it goes through several options. Hit it once and it may want to go to just the external, then both the laptop screen and the external. etc. Now Fn + F6 turns the backlight bulb off on the internal monitor to save energy. Now I am giving up the link to your service manual, it is in PDF format so you can make a copy for yourself and keep on the laptop, print it or save it to a flash so you can reference it later. I believe if you take the keyboard off and disconnect the video lead on the left side where the display plugs into the motherboard, then when you power the laptop back up it will default to the external cord and you can use the laptop without any switching. That is what I am doing with an Aspire 5920 that I am rebuilding. Good luck, ParrotHead PC Repair Just copy and paste the link below to you internet address bar and hit enter.
