I bought a Microsoft Laser Desktop 7000 keyboard and mouse a few weeks ago. I inserted the included rechargeable battery straight away and used it until it ran out of charge. The trouble now is no matter how long I put the mouse on the charger, a message pops up saying the mouse battery is critically low.
When I put the mouse on the charger, the red led on the mouse flashes so I assume it is charging. I've tried putting an Energizer 900mah battery in there, but the same problem occurs. Any ideas?
