Q: wireless mouse keeps losing connection?

This is probably a mechanical problem, not an issue with your Bluetooth conneciton or the mouse software.

The batteries are probably disconnecting - No power. No bluetooth.

Try this.

Flip your mouse over and remove the battery cover.

grab your business card and fit the end of it across the compartment - you're going to create a little padding between the batteries and the cover.

Mark the width on the card with a pencil and cut the card to fit.

Place the card on top of the batteries and close the cover.

The switch is going to need a fingernail to slide it now, but your batteries shouldn't disconnect as you move the mouse around.

Or try this.

Get a little aluminum foil, fold it up into a little square and fit it between the -ve end of each battery and the springy contact. Not as secure but does the same thing.

I also had the "intermittent" problem  with my magic mouse (but not my wireless mighty mouse) and it was driving me nuts....

I thought bluetooth was the problem

Did the tinfoil at the + end of the batteries, and problem solved....

Upon further inspection, the plastic is quite thick at the + end of the housing, and the batteries + end was short(ish), just enough to make contact sketchy.

So back to using my favourite mouse

Thank you.

I actually have now modified a couple of sets of rechargeable batteries..

If you are handy/comfortable with a soldering iron, you can put a small dab on the + ends, then shape to optimum length for a snug fit....

Did this several months ago, and works like a charm...

Better than  original tinfoil fix (which does work too)

Love this fix! It worked!!!

Thank you so much!
