Calculator restarts randomly

[Benjer]

I had been having an issue similar to yours for several months, ever since the latest firmware update. In my case, the calculator would occasionally randomly reset after a keypress, or within 1-2 seconds of a keypress. Like with your case, all data entered since the last shutdown would be lost.

My work-around was to turn off the calculator after obtaining my result so that data would not be lost, but this was not perfect and a bit of a hassle.

Here is a post I made in another thread about the issue I was having.

Now, since then, I've made some changes to the settings in the calculator and the issue seems to have gone away, with no resets in the last few months. Regretfully, I have not figured out which exact setting or combination of settings it was but I think it has something to do with the complex number or i settings in either Home or CAS mode.

Currently I have "Complex" and "Use i" disabled in CAS, and "Complex: a+b*i" with the adjacent box checked in Home.

I hope you find a resolution to your issue.
