Magic Mouse not flash green light even replace batteries i need your help?

With no sign of coloured light it points towards an internal failure, something which we cannot advise on here. The green light indicates connection and you don't have connection. So.

If the mouse is still under warranty you will have to get it back to an Apple store for their evaluation and probable replacement.

If the mouse is no longer under warranty you will need to replace it. I see no other solution as the mouse is not repairable.

1. Cycle the On/Off switch.

2. Ensure the batteries are compatible, and correctly installed.

You should not expect to see a yellow flash.

What computer are you using?

Since the mouse is not working, what mouse are you currently using?

Open System Preferences...>Bluetooth>...what devices are displayed?

seventy one's post seems to be the only solution.

If it doesn't show a green light with new batteries you need to check

1. If the batteries are connecting properly. Low quality batteries may not be the right size. Shake the mouse to see if there is any sound to indicate movement.

2. Is the connection point in any way contaminated by a previous battery that was found to be leaking. If so clean that point.
