Drained battery if not started for a day. Mechanic cannot fix something that is not broken. New battery, alternator and starter fine. Put computer to sleep, no draw on amps. Seems to happen quarterly, after.

If it is killing the battery that fast there has to be a drain on it. Something is turning on after a set time, like an alarm system. If it does not happen all the time it will be difficult to find.
