All the laptops I have - do have removable batteries (unless you count 2032 cmos ones - that are harder to reach). I have opened all of them, upgraded, repaired (as in mosfets/capacitors), cleaned, etc. One of the phones has a removable battery(!), still. Pretty much any other device/appliance has a plug or a mechanical switch (or both).
