This is quite surprising, NoVRAM modules don't handle the power control signals required to overcome an AUTO POWER OFF situation under some circumstances.
- 1st NoVRAM is configured as an Advanced HEPAX.
- 2nd HEPAX page is mapped into an even page.
This is by no means harmful to your calculator nor the contents of its memory. A simple workaround consists in unplugging and reinsert the NoVRAM module, after that you can switch your calculator ON normally.
When used on a C or CV, HEPAX will place itself in page #5, unless you've got a TIME module inserted.
On a CX, TIME is standard in page #5, so HEPAX usualy goes to page #6 where the problem arises.
So, regardless the functionality of the Dbl. X-MEM (which can of course be faulty), I'd like to know if your NoVRAM is configured as Avd. HEPAX and, if so, confirm the tests on your CX, whith the NoVRAM module only.
Let us kown of the result please.
