Just wondering: a) do you have a bluetooth keyboard, and is it encountering the same problems; b) have you tried connecting the bluetooth mouse to another device and does it then still has these problems? – Vincent Apr 2 '13 at 0:39

Try doing the following steps. This will cause a PRAM reset.

  1. Choose Apple menu > Shut Down.

  2. Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.

  3. Turn on your Mac.

  4. Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.

  5. Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.

  6. Release the keys.

OS X Yosemite nor devices with PRAM was NOT available back in Apr 2 '13 – alexus Apr 15 '15 at 15:08
Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Cfinley Apr 15 '15 at 15:54
