help my hpprime does not start [solved]

[JanneF]

Hi,
I unboxed my physical Prime the day before yesterday. It is a "hardware version C" (G8X92AA#B1S) and is now upgraded from Rev 6030 to 8151. It indicates 100% full battery but still after hours of charging it instantly dies when I disconnect the USB cable.

I have tried disconnecting the battery and it doesn't matter if the calculator is switched on or off when the battery is put back. Problem remains Is this a rare problem or am I likely to get another faulty calculator if I try to get a replacement?

I live in Sweden and sadly the only reply I got from HP support here is:
" There is no longer any support from HP for this product "
