Connected to new computer, new batteries in keyboard and mouse with no connection, pushed connect button to both but does not work

You say the mouse works OK. You also said the battery is new--I take it you are talking about the keyboard battery.
1. Is the keyboard battery installed correctly?
2. Have you pushed the "connect" button on the USB antenna?
3. Have you pushed the "connect" button on the bottom of the keyboard?

If you have done these 3 things, you should be up and running. If not, you might go into the device manager and delete any keyboard there and try restarting the computer to see if the keyboard is detected.

Your computer also has a connect button. If it is a USB optical mouse, you must push the connect button on the receiver that is plugged into the USB port as well as the mouse (and keyboard if it's all a set) If the mouse receiver is in the PC, like some Sony's...look around for the real tiny reset button..it's there somewhere.

hello
under your keyboard and mouse you can find a little(maybe red) button that you need to push so your keyboard connects to the computer transceiver. check also if the transceiver have an button if so, then push that first and then the keyboard and mouse.

The mouse and keyborard have to be in direct view of the reciever. Even a small obstruction will effect the operation

Normal 0 Press the Receiver button (and the lights will start flashing.
Then if the Keyboard isn't working, press the small RESET/CONNECT button on the back of the board to connect the keyboard to the receiver.

If the MOUSE isn’t working, push the small RESET/CONNECT button on the back of the mouse to connect to the receiver. Then they should work okay.
Hope this helps. Bud
