Question about HP 49g+ Calculator
I bought an HP 49g+ calculator about two years ago. I don't use
it very often, when I tried to press the "ON" key to turn it on,
the calculator would not turn on.
Changing batteries did not help either.
If batteries are fresh use a paper clip and insert it in the hole (reset) to the left of the serial number. Press gently.
Hope it helps.

Hi, if pressing on and F5 together immediately starts the selftest your keyboard is OK, but one of the capacitors on the HP49G PCB are broken. I replaced all three and the turn on/off problem was gone.
Hope this helps.
