Question about Logitech Cordless Desktop Optical Y-RK49
Cannot use keys on keyboard to enter addresses or searches. Cannot enter password on my user log on.Computer has two users. User without password also has no reaction to key entries.For instance when clicking on Google search bar,I get the intermittend flashing vertical bar inside the search bar, but when I start typing nothing registers on screen. Also when using mouse cursor to click on a spot in the browser address bar, every thing is normal untill I press delete in order to be able to enter a new address. Nothing happens. My keyboard connector appears to be normal. I installed new batteries also in mouse. I tried many times to reset the connection by depressing the connection buttons on both mouse and keyboard. The mouse green LED light is on. Any suggestion on what to try will be very much appreciated. THX Andy. i dont know what mine is but nothing typson my keyboard its ike its locked i really need help before my parents find out. right now im using the onscreen keyboard can someonhep me

SOURCE: 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!

When you boot up to the log in screen type in administrator as user to log in if you cant log in
during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS using the arrow keys scroll down to set user password or supervisor password you can change or remove your password from there
The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard.
Another way is to reset the clear CMOS jumper on the motherboard itself.
Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.
cmos battery Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment. Although on some motherboards the Cmos battery is soldered in
Often many users will leave the administrator account alone or have other accounts with administrator rights. If you're not logging into the computer as administrator or have other accounts follow the below steps to reset your other accounts password.
Reboot the computer into Safe Mode
During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer Advanced Boot Options screen appears.
Select the Safe Mode option using the up and down arrow keys, then press the ENTER key. Choose "Windows XP Home/Professional", depending on the version of the operating system.
Press ENTER. Shortly, the welcome screen should show.
Log in as "Administrator". Click Yes to not use System Restore Mode.
Click the Start button. Choose Run and type in "control user passwords" (without the quotes). Click OK.
Select the "Administrator" user. Click Change my password. Enter a new password in the corresponding text boxes. Click OK. Write this password down and store it in a secure place Close the User Accounts window and restart Windows.
In User Accounts select the account you wish to change the password for, click change password and then enter the new password or click remove the password to remove the password from the account.
If all else fails you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard
Many RTC's require an external battery. If your RTC is one of this type you can clear the BIOS password just by unsocketing the RTC and reseating it
click start type cmd press enter. this will vary depending on your operating system
-Type control userpasswords2 then press enter
- With the User Accounts window open click on the Users tab.
- Clear the box that reads "Users must enter a user name and password to use this computer." and click Apply.
- A window will appear asking you to enter the name and password for the account you want to automatically log into.
- Once you have entered that information click OK to close out of that window and again click OK to close out of the User Accounts window.
click start type cmd press enter.
this will vary depending on your operating system
Hope it helps
