Question about Computers & Internet

1 Answer

I have a new wireless mouse model K72278CA and it was working wrielessly until I dropped it on the floor and one of the batteries fell out. It wasn't harmed otherwise. I put the battery back in and it looked like it was ready to go but when I clicked it to activate it, it wouldn't move the cursor. The only way it will move the cursor now is if I plug it in to the USB attachment. Do I have to reset something somehow?

    How do you reset the "Channel"?? There does not seem to be an opening anywhere that might allow such a thing to happen. There is a sideways isoceles triangular hole in the bottom which contains what appears to be a small screw on the left side of the triangle (which would be the top if it were vertical) I am not able to depress or to move it. Any other ideas??

Each time you remove the batteries you need to reset the channel so the mouse and the device are on the same channel so they can communicate.
I hope this helped.
Good Luck.

    Did you get a manual with the mouse?

    Look on the CD if one was included with your mouse, which may contain instructions and pictures of what to do to get the mouse to communicate with the USB device.

    Good Luck.

Unscrew the mouse and check for the contact and adjust the alignment of the casing to the click switch contact. Reinstall the HP wireless mouse software that might reset the settings. Have a nice day.

You need to 'reconnect' it. You didn't specify the exact model of your wireless mouse, but most types have a special 'connect' button on the receiver-box of the wireless mouse or on the bottom-side of the mouse itself. Just press this 'connect' button and you should be fine ...

Keyboard not working


To connect the keyboard or mouse to the computer, you must connect the wireless device through the USB port and get it to hold a good connection. You do not have to install any devices to use these products, they automatically work when you plug them in. When it says that the device is recognized, you are ready to use it! If you have a desktop, you can also plug the wireless device to the mouse port. The keyboard and mouse work properly up to 5' away from the connected wireless device. If you can get the wireless device to work properly, you should have no troubles with the product.

LX7 cordless optical mouse with dongle


Hello,

Had the same problem. But before filling the logitech RMA from to get a replacement, I put new batteries into the mouse and the mouse worked again.
I am using rechargeable batteries, and I seems to me even if the green light on the bottom of the mouse is on, the driver warning for low battery does not come on. May be the volage drops to fast with a older set of batteries.

Try out new batteries. Hope this helps.
I am using the LX7 mouse for more than 2 years with lost of abuse (>10x drops from shoulder hight to hard office floor, sitting dongle in my pocket and dropping my backpack onto the floor with the dongle on the botton in the backpack).

Regards.

Not working


If there any lights on the mouse when you put new batteries in the mouse? If yes then you can still fix it. On the usb controller of you mouse it will have a button on it. Press that button first and then press the button under the mouse. Repeat a few times and see if mouse responses. Then if nothing happens, unplug the usb controller and place it into another port. Repeat the above process and see what happens. Should work fine.
