Question about Microsoft Wireless Laser Desktop 4000 Keyboard/Mouse

3 Answers

Microsoft Wireless Laser Desktop 4000, can't use mouse and keyboard simultaniously.

I just bought it from Office max... costed me a good $70, thing is, i play WoW and Guild Wars, and the mouse seems to override the keyboard. I hold a button on the keyboard and it keeps going, but i move the mouse more than an inch and the keyboard button stops being pressed, I then installed the software it comes with, re-booted and it is still there... anyone know?

I have this KB and Mouse and have had no problem with WoW, Guild Wars or Silkroad. It may be the processoer is have problems processing the inputs. Check for software updates,

Seems to me that this happens because there is one input to the computer from both the keyboard and mouse so the computer can only get one signal at a time. So when you are runing with 'w' and move the mouse the new signal cuts in. Likewise if you are running with the mouse, ie. holding both buttons, and hit a button on the keyboard the mouse will cut out. Soloution: get a different keyboard, mouse with input to the computer from both the mouse and keyboard.

Microsoft 4000 wireless keyboard is not working

Look under the wireless keyboard. There is a door to install batteries. It sounds as though you just need to replace the batteries on the keyboard. I think that they're AA.

Good luck!
