I have a very serious problem.One day I just couldnt turn on the calculator.I pressed the reset button but the calculator was still dead.I measured the voltage in the batteries and they were almost dead.So I put a set of new batteries.However the calculator was still dead.No reset worked,not anything.Then I noticed a little hole on the left upper corner of the backup battery compartment.Inside this little hole there seemed to be 2 copper pads,so i thought that if I short circuit them,something might happen.And all of a sudden the calculator became alive!!! However on the screen there was a message informing me about a fault in the OS and that it needed upgrade.So I connected it to the computer and started upgrading.All of a sudden the upgrade stops and an error message appears.I disconnect the calculator,I press reset and it shuts down.So I tried to short circuit the 2 pads to get it back on...Nothing! The calculator was now seriously dead.I have done almost everything imaginable to turn it on but to no use.In a nutshell...Im desparate,please heeelp!!!!!
