magic trackpad keeps disconnecting

You're not alone. Mine began doing this within the past month, too. I replaced the batteries and it made no difference. I'd been waiting for the batteries to run down and see if the next pair were better, but now I see that's unlikely. My trackpad came with my iMax, which I bought a little less than two years ago.

I am having a similar issue.

My problem is with a new Magic Mouse bought two months ago along with a new iMac.

Batteries are 65%. I have powercycled everything and unpaired/repaired the mouse. Nothing seems to help.

I saw somewhere a reference to other bluetooth or wireless items in the neighborhood of the magicpad. I think this may be part of the problem. Yesterday I was experiencing the problem a lot while I had another laptop open receiving WiFi. At the moment it's off and my cell phone is away and I haven't had a problem all morning. If that applies, you might try moving things away or shutting them off just to see what happens.

I was JUST about to make a post about this. I've had mine for over a couple of years and it's been working just fine. Just recently, I've noticed when starting up my computer, it won't pair. At this moment, the computer won't even find the trackpad now. I'm really disappointed. I actually really like using the trackpad and I don't know why it suddenly won't work. I just put fresh batteries in it too but still nothing.

Something is up. I've had mine two years, too, and got used to it. Suddenly something's affecting them. Like i said earlier, today I'm having no problems (so far) and it could be the fact the other lap top is shut down. I will be opening it in a bit to do some work I can only do on it, and if the problem starts up we may have something.

Are you guys saying that just the presence of another bluetooth peripheral (keyboard or trackpad) may be causing this problem?

My environment is that I have a new, unused wireless keyboard and a new, unused trackpad in the next room to where my iMac is located. I've never paired either of these with with my iMac.

With my iMac, I use a wired keyboard, and wireless magic mouse.

I'mnot sure . . . In my case, it's an old Fujitsu laptop that was on yesterday and I was having consistent problems and now it's off and I'm not. So, if I pay attention I may find that's it. I've been using both for the past two years and it's never happened until a couple months ago, so it's something to do with a new OSX update, i'd assume. I have a wire-connected keyboard, so I can't be sure if other Mac bluetooth products would have the effect, but I'm ready to believe it's the presence of a foreign WiFi laptop that's interferring.

I placed a small peice of aluminum foil inside between the battery and the enclousure. Seems to be working fine now.

I've had a magic trackpad for a few years with no problems. Recently it started the constant connect/disconnect routine too. I had recently replaced some Duracell batteries in the device with some off-brand AA batteries that came with my Comcast remote (Golden Power batteries) that I hadn't previously used. The battery level indicator on my Mac showed they had sufficient power (83%), but when I replaced them with some Kirkland (Costco) batteries, the trackpad paired immediately and has worked fine since. My advice is to change battery brands and try again, especially if you are using an off-brand.

Yes, I think it's a battery problem when this happens.
