Is there any sign that the old batteries may have leaked at all?
Are you sure that the "new" batteries are really good?
Maybe try gently cleaning up the battery contacts in the calculator, and the battery ends for that matter, say with a typewriter eraser.
For a warmstart, press and release the C key while holding down ON, then release ON, but the Reset under the rubber foot should've forced a warmstart anyway.
For a memory clear, hold down ON, A, and F. Release F and A, and then ON.
For a repeating self-test, press and release E while holding down ON, then release ON. Do a warmstart to break out of the repeating self-test.
