Laser mouse 8000 won't connect to blue tooth

Wireless mouses and keyboards don't use blue tooth to connect. Whwn you get a new wireless mouse, there will be a new dongle to replace the one form the old mouse.

You need a blue tooth dongle made for the beats headset. Keyboard and mouse dongles are not universal. They work only with the keyboard and mouse that it was designed to operate with.

The wireless dongle plugged into the computer is on a specific frequency and you wont be able to peer it with a different mouse. However if it is a Bluetooth and not wireless, you can pair another Bluetooth mouse no problem.

Yes, you can. Bur you need to insert the dongle to USB port which is came along with the Keyboard. Also install the driver for the same.

maybe you need to download a patch download to repair it

Do not use device causing issues. Incompatibility problem.

Deleted the mouse from bluetooth and then added again.found info at

Hold on... are you sure that you have a bluetooth mouse or do you have a wireless mouse with "pen drive" like dongle? If it is with a dongle, it probably is a common wireless mouse which operates on its own wireless frequecy. You may have a driver CD that comes with the mouse or it simply works "plug and play". However, there are bluetooth mouse too, in this case you just need to turn on your bluetooth on the PC and pair the mouse with your PC just like any other bluetooth device. In either case, a LAN card in not involved. Hope this helps.
