Very strange fault

Hi All,

There must be a Mac expert on here that can give me some guidance.

The fault is with the keyboard and track pad. Once the mac has been on 10min or so. The keyboard and track pad will cut for about a second or two and the come back. This seems to happen about once a minute. The strange thing is, when I plug a mouse and keyboard in it works fine.

I have reinstalled the operating system and the Apple store has no idea.

I have a Macbook Pro Core 2 Duo 2.53 GHz. I am running Lion however this fault happened before I upgraded.

Any suggestions?

Thank you in advance.

I've had this happen as well, but pretty infrequently..the keyboard or the mouse will disconnect and then come back..I notice this on my new Magic Trackpad as well..but it only happens once a couple of days or something and once reconnected it doesn't do it again, so I just chalk it up to being wireless..
