Cut a small piece of paper a little shorter than the length of the battery and about twice as wide.

It also explains why it only charges for a few seconds–just until the battery slips out of position and loses contact. Notice the short tip on the rechargeable battery and the rails pressing back against itĪs a result of this plastic getting in the way and preventing the battery from making contact with the positive conducting plate, of course it can’t recharge. Since the metal plate is tapered inward, it only makes reliable contact with the battery when the battery is pushed all the way down into the compartment. When putting the battery inside, the rails tend to press back against the top of the battery such that the battery’s tip doesn’t make good contact with the metal.

There is a small hole under the battery, but no switch or button in the hole. However, the mouse I was having problems with did not have such a button. I saw online that some people have found some sort of button underneath the battery and that it’s not being depressed.

Taking the rechargeable battery out also results in the flashing red LED. When placing the Laser Mouse on its charging cradle, the LED on the top of the mouse slowly flashes green for a few seconds, as if it was successfully charging the NiMH battery inside, but then switches to rapidly flashing the LED red. Ran into a situation with a Microsoft Wireless Laser Mouse 7000 that also seems to plague the Wireless Laser Mouse 8000.
