SOURCE: Acer Travelmate 8100 when pressing fn and f5 nothing happens

I found the problem. The drivers needed for the keyboard are:

Windows\system32\DkbFltr.sys
provided by Dritek System Inc. Version 1.3.00
Windows\system32\8042prt.sys
Windows\system32\kbdclass.sys

I looked at the current drivers for the keyboard. Somehow the keyboard must have been reinstalled or drivers got corrupted. I did a system restore to a time before I installed some new hardware and drivers. Then I looked at the drivers for the keyboard through the control paned =>
keyboard =>
hardware Tab =>
Standard keyboard =>
properties =>
Driver Tab =>
driver details.

And found that the drivers were different except for the last one in the above list

You can update the drivers. Do a search for the first one in the list and the second one in your windows directory(search for hidden files and system files). I found the files in my system32/drivers directory. You may also find it on the disks that came with the Acer.

I have looked on-line for the first one and could not find it. perhaps a better search term swould find it. I also looked on Ace rs site.

Good luck,

Wybmasiity

Hi, I have a problem with Aspire 5570z The problem with 5570z is this: my Screen is blank with power and sound is on.


Unless the backlight has gone bad, try Fn+F5 and Fn+F6 keys to see if your display returns. Fn+F5 toggles to an external screen; Fn+F6 toggles the backlight on and off.

Monitor is dark. how to fix?


Walt, hold the Fn key down again, and tap once more on the Acer, F5, Display Toggle-Over key.

There are at least 3 display options available;

1) Internal display of laptop ONLY

2) Internal display of laptop AND external display

3) External display ONLY.

Were you just using the external display for more 'display real estate room', or was/is there a problem with the internal display of the laptop?

Was no problem? Is now? Even when using the guidance stated above for the Fn and F5 key?

Then if your laptop uses a CCFL for a Backlight, it also uses a screen Inverter. Screen Inverter is bad.

If it doesn't use CCFL/s for a backlight, and uses LED backlighting, replace the LCD screen.
The LED backlighting is incorporated in the LCD screen assembly, and you ain't replacing it.
Replace the entire LCD screen.

Post the laptop manufacturer name, and model number in a Comment. Model number is on Bottom of laptop.

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.

Try (on the bottom of the laptop) removing the door to the RAM, and pulling one stick out at a time, than starting it, and than the other stick, and starting it. If you still have a black screen, than the motherboard has gone.

Hello wall flower hi, when you turn on the laptop, did you see the start up screen clearly? can you read words on the screen, and then it goes dark? If this is the case, check first the Fn key with the corresponding display for projector, (usually Fn+F5) this combination key is used to display the content of your computer to the LCD or Projector, IF not such a case, it may be problems with your laptop inverter board that powers the backlight. Check your bios settings also.

Screen not working but other monitor work


Your "F"keys are multi function. Look for the one with a picture of a monitor. Press the FN key adt the appropriate F key at the same time. You are probably in remote monitor mode. The F key is usually F5 or F8.

Dark screen ,fn does not work


I would suggest connecting the laptop to an external monitor, just to make sure that it is all running correctly.

If you can see a very dim image on the screen then the backlight is out. This can be a light problem or the inverter that powers the backlight could be bad. The inverter is not real dificult to change and also is not very expensive. If it is the backlight tho, it is easier to just change out the entire screen.

Hope this helps
