Help!

I have an HP 28-S calculator which I purchased a couple of years ago.
Lately, it has been resetting itself with no apparent warning.
(e.g. I turn the calculator on and it beeps and the MEMORY CLEARED
message appears.  Sometimes my programs are still there despite the
message.)  This has happened about four times.

I thought perhaps the batteries were getting low so I replaced them, but
it has happened at least once since then.

A friend of mine bought a 28S about the same time.  His started doing the
same thing a while ago until it stopped working entirely.

I am wondering: is there is a known problem with the 28S ?  Is my
calculator doomed?

Some people have suggested to me that this is a problem with different
sized batteries, but this doesn't explain why my friend's 28S died completely,
unless he had two unrelated problems.
