Re: frozen keyboard again

First, change the batteries on both the mouse and keyboard. Reset the connections. Reboot. You should be okay.

When I type on my logitech ultra thin keyboard cover it gives a different character than the one I typed. Is it possible to repair?

not al keyboards are the same. even though you have a qwerty key board the country language moves the actuyal key location around. I am thinking that the keyboard you have is set for england and you want a usa set keyboard or sime other country keybhoard. The boards are set out the same but certain keys print not what you expect. Go on the web and tyep in keyboard layout for more information on how to set it out. I have done it but it was so long ago that I have forgotten how but I do remember that the process is really quite simple.

Hi, I've got 2 eeepcs, with identical problems,

When the RH side of the keboard types numbers instead of letters then the Num Lock (number lock) key has been pressed.
Press the Num Lock Key again to return to letters again, usually this is usually done by pressing the Fn key plus and probably the Scroll keys, this key will be also marked NumLk, and there will be a LED light that will indicate when the number lock is on.

Logitech cordless keyboard erratic after cleaning keys

seems to be that you may have accidentally swept some dirt underneath the keys.
try pressing each key individually in word and narrow down the affected key or keys, then remove the affected keys (using a keyboard key removal tool, or very carefully by hand) and clean underneath the key with a small dry clean brush both under the key and the board section it lay in, then replace the key and type the key again, if that has no luck then try the process again.

hope this helps

Wireless keyboard problem

just called Logitech support (who were more than helpful, very friendly, and picked up the phone within 5 minutes).
I have an MX3000 laser combo set and the receiver lost connection to the mouse last week. Then the keyboard went out a few nights ago. I had tried what everyone else here had tried to no avail.
So I decided to give a tech support line the benefit of the doubt and call one...
I'm very glad I did!
Here is the entire process for the Left Ctrl + Left Alt + F12 keys. First, when you hit these keys together, a box should pop up on screen to prompt you to reset the encryption sequence. That is what these keys are for. If nothing pops up on your screen (as was my case!), wait a few minutes for the button sequenece to time out, then hit these keys again. Make sure its L-Ctrl + L-Alt + F12 only. Within 2 seconds after that button combo, hit connect on the receiver. Within 2 seconds of that hit connect on the underside of the keyboard. Within 2 seconds of that, hit your Escape key on the keyboard. Sounds completely ridiculous, but this is the direction Logitech support drove me in. And it worked for me. And this is after I tried everything imaginable for over the past week.
We then moved on to the mouse, which i thought we had fixed. But now i have one working and one not working, so I think I need to re-run through this whole process to fix the second mouse. Basically, I now have 1 mouse that works on both receivers, on 2 different pc's with 2 different keyboards in two different rooms (both sets are MX3000 however).
The other now seems to have lost the signal. Will update if I get that second mouse to play nicely with me.
Hope this helps anyone about to trash a perfectly good unit like I was!

Keyboard problems.

1. Restart the PC. 2. Hit F12 key repeatedly as soon as the PC turns ON. This will bring up the Boot Menu. 3. Select DELL Diagnostics. 4. Select the Complete / Full from the list of options. 5. Let the tests run which may take about an hour. Make sure you are there in front of the PC for the first 10-15 minutes, because it would need your inputs. 6. This will test the keyboard and USB ports too. 7. This will also verify for you whether the keyboard works when Windows hasn't started. 8. If all the tests pass and your keyboard is still working after sometime, you have issues with Windows: Start you computer in Safe Mode and check the USB drivers and the keyboard drivers. 9. Now, if you continue having issues even when you are running the diagnostics, you need to check your hardware viz. keyboard (try installing another keyboard if you have one) and the USB port. PLEASE REVERT BACK WITH THE RESULTS. I WOULD LOVE TO HELP YOU FURTHER ON THIS, IF THE ISSUE CONTINUES.
