Well, maybe some of you also appreciate Sharp pocket computers in addition to our beloved vintage HP gear!
I have a "new old stock" Sharp PC-1600 which, altough looking absolutely perfect and unused (including its battery compartiment), beeps every 2 or 3 minutes since I put fresh batteries (4 x AA 1.5V).
I tried other batteries brands (Panasonic, Sony, GP, Duracell), either alkaline or not, with no succeed. The PC-1600 powers up fine, and seems to work fine, but after approx 2 minutes, it beeps and locks up. When powered OFF, it wakes up, beeps, and locks up.
Any idea is welcome. Thanks in advance.
