don't bother removing all of the aaa's, removing one is sufficient as
there are only two connections on the main board for power. (aside from
the lithium)
>fun part: let it sit for about 1 hour. Now, replace all batteries and
try just holding [on] down again for a minute or so. this will drain all
(hopefully) power out of the circuitry (including ram) if you're really
impatient, you could bend a paperclip up funny and short together the
contacts where the lithium battery used to be. there's no eeprom/flash
memory in the 86, so once the power is drained, everything but rom is
erased and the calc should think it's being turned on for the first time.
if you really want to understand what's going on, take an electronics
course, then find out how sram and microprocessors work.
