Logitech EX100 F-lock problem

As you might know the EX-100 has a software glitch that makes F-lock off by default. Sometimes but not often it turns on after reboot. Is there a way to make a shortcut of some kind and turn it on in the registry ? Or does anyone have any other tips? And no I'm not buying a different keyboard, I've had lots of problems with keyboards(cheap strange brand crap) and this is my forth, thought I'd go with a Logitech, well known brand and all, but no no no PLZ help me ! ;)

    f-lock = funcion keys F1-F12.
    I can only use them like once a week.

    There is NO f-lock key that's the problem.
    It was going to be Software controlled but they forgot to add that little piece in the software. Too bad for us suckers that bought this keyboard.

If you have no use of the keyboards' special features you can uninstall Logitech Setpoint. I have tried that and everytime I boot the F led is on.

I ran into this problem today and had to get access to the function keys. In desperation I plugged in a spare, hardwired keyboard into the back of my laptop while leaving the wireless keyboard on and operable. It worked great! This however is unfortunate thing to do you have to use the F-keys daily and especially if you take your keyboard along with your laptop like I do but it works OK.

I just talked to the Logitech support on the phone, and they say it´s a software problem on this model. And the only way to fix it is to buy another model of keyboard. Too bad it was a while since I bought it and cant return it to the shop. And there´s no plans from Logitech to release an update of the software either. So think twice before you buy Logitech crap. I really love the feel of this keyboardm but with this shit... I aint gonna recommend Logitech to anyone.

Well i had the same problem for an hour now and I fixed it by restarting windows and unplugging both the USB and PS2 cables. When windows started again the F LED on the receiver was turned on and the F-Keys were working. Btw before restarting I also removed the Logitech SetPoint Process from the Startup Tab in msconfig. To run msconfig, press Start>Run and type "msconfig".

My casio digital camera ex-100 exilim seems to be frozen. The camera just turned off during use, but the lens did not go back in. No screen lights up, bought a new battery and fully charged, but nothing....

The next thing to try would be to take the battery out and let it go for a few hours and then try to insert the battery again and turn it on...
may work.
But probably a ribbon cable has come off inside and that is why it is not working anymore.

HP Photosmart C7200. Printer is not printing the bottom quarter of the page, despite print preview showing the whole page fits within the margins. I am using A4 paper

Try reseting the printer to factory defaults- also does the same problem happen when you a printing from a computer or trying to print a scan directly on the printer?

try restoring the printer to factory default settings, you can also try reinstalling the drivers on your computer.

Direct TV states "Not available" on screen.

When your Direct TV based units say that a channel is "not available" when you know that you had been receiving them on a regular basis you probably have a problem with the activation card. Sometimes the unit will lose it's communication with the satelite and it will not restore it when the signal reappears. This is probably a software issue but happens so rarely no one wants to fix it.

If all the other menus and parameters of the system appear to be working the problem probably lies with the activation card. For many reasons the card can become unusable and cause the system to not work. Generally though it is caused by a glitch in the software. As the unit continually reacquires the satelite or satelites, it must execute instructions just like your computer. We all know that computers are prone to failure so why not satelite dish receivers.

The solution involves removing the card then reinserting it and hitting the reset button near the card slot. This will cause the unit to reboot and re-acquire the satellite and all the programming. By forcing the unit to reboot it must read the information from the card and reload the software. Once reloaded the software will no longer have any glitches in it and should work as it is supposed to.

This should solve your problem. If it does not you may need to call your satelite provider.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank You.

Have cordless keyboard EX-100. Keys will not respond. The calculator and mute keys works all other do not. Have fresh batteries and reset connection button many times. My cordless mouse is okay.

You either need to push fn button (upper left on keyboard) or you need to check that the logitech keyboard software (itouch and a few other names i can;t recal) is running or installed. On mine if the software has glitched out, a quick reload of it and it works fine. This software is what is telling your computer what the special keys mean. If this isn;t running it will only be able to understand the standard type of key signals.

Instead of lock code, enter security code. Its defaults is 1234 or 12345, like this series depending the spaces given to you to fill . EX. If the spaces are 8 then code will be 12345678. NOTE: This information will work if your codes were at defaults.

Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it to Reset/Connect the mouse to the receiver and work properly.
If not, try pressing the receiver button and then press the mouse. This should be done whenever you change batteries or glitch.
