LOST THE TRANSMITTER FOR THE LOGITECH MK300 . WHERE CAN I GET A REPLACEMENT

If you do not have the Bluetooth dongle (plugs into a USB port) you should contact Logitech for a replacement. Alternatively you can also look for one second hand via craigslist, ebay, etc.etc.

MK300 does not indicate if caps lock is on or off with lights. It will show a message on your screen for 2 seconds when you press it. You will need logitech setpoint on your computer for it to work tho so here is the download link http://www.logitech.com/en-us/584/3131

Found replacement transmitter at Logitech store online. $10 + shipping as of 5/2013 . Here's the link.

You push down on the top cover and slide the top cover back. There is a diagram here:

The top part of the mouse slides out. It is the section where the name logitech is written. Check the picture to view the mouse with open compartment.

go to logitech.com support plug in your model number and download the setpoint software from logitech for your particular product. Should then work fine.

Yes, you need to install the Logitech transmitter for your cordless mouse. The acer transmitter uses a different frequency. You could try pressing the connect button on both the existing transmitter and mouse but that's not likely to work with different manufacturers.

I have the same problem. I don't know where to fix/replace the transmitter.
