You have probably used to many giggahurks on your computer up I would go to control panel and click on uninstall programs and take off everything you have currently installed or downloaded but don't just uninstall anything do it to things that you barely ever use like gaming systems then on you're control panel go to system and security's(find and fix problems) after you do that go to troubleshooting computer problems and that should pretty much help you with you're black out problem(:

What's your protoshiba satellite A205-S5880 display function keysblem?


Remove the battery. Keep pressed power button 30 seconds. Reinsert the battery. Try again.
If not let it start like this - black screen. And press ONE TIME FN and F5 until the screen comes back again. OR FN and F9.

My screen lights are at half strength. The F4 and F5 buttons do not work


Maybe you have to press and hold the FN function key at the lower left side of the keyboard, then hit F4 or F5. Most times just pressing F4 or F5 will not work.

My samsung r20 backlight keeps going off, if i press the Fn and F5 button it comes on for a second and then back off


If you can see the images on the screen very faintly when you shine a flashlight on the screen, then your problem more than likely is the LCD Inverter. The LCD Inverter costs less than $10, but you will have to disassemble the lcd screen to get to it.

I'm sure you know that you can attach an external monitor to your laptop and hit the FN key and hold it while you hit the correct F1 thru F8 key that will display the image on the external monitor? This could be a solution until you get the inverter fixed.

Now a dishonest repairman will take advantage of you if you take that laptop to them talking about the backlight is going bad. He'll simply bill you $300 and tell you he had to replace the LCD Screen which houses the back light an most times it's easier to replace the screen then fool with the backlight. And in your case all he would do is replace the lcd inverter that sits under the lcd screen and is covered by the strip at the bottom that goes around the lcd screen.

I used The FN and F5 key and it worked


Go to the point where you have a stable picture even if it is huge. Right click on an empty space on the desktop and scroll down to properties. Click on settings and increase the resolution a little at a time hitting apply and checking the display as you go. Keep hitting ok to the display settings if you like them. Find the resolution and display size that suites you.

Toggle Between Laptop and Monitor


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.

ACER cracked screen..external monitor???


Hi there.
The keyboard toggle you are using is the correct one.
Sometimes you have to hit Fn + F5 a couple of times to stay on there is no real set time. Make sure Fn + F6 is on so the laptop screen stays on.

Good luck and thanks for using FixYa!!

Toshiba a105-s4054


Try pressing the following 2 keys simultaneously- Fn & F5. Do this only once. If this doesn't fix the problem, be sure to hit both of them simultaneously 1 more time to set the machine back in it's original state. What you are doing is switching between the internal monitor and an external monitor, should you ever have a reason to attach one.
