New Prime G2 - Bad Keyboard?

[djeffries]

I just purchased a new HP Prime G2 from Best Buy. When I powered it up, after selecting language, it takes me to the 4 page setup screen. However, I have been unable to complete the setup because most of the keys do not seem to do anything. Some of the letter keys seem to work sometimes(A through N), but number keys cannot be used to enter numerical data. Many other keys refuse to work as well, such as Help, View, Menu and CAS.

As it is this device is totally useless as a calculator. On HP's support website, no support is available for calculators. The serial number for this unit is not recognized.
From the HP Connectivity Kit, it reports
Application Version: 20181016v14181 (I updated the Firmware to the latest version, but it made no difference)
Operating system version v0.050.640

This seems to be a hardware fault, not software. Because of the way HP packages these units, they cannot be tested for functionality before purchasing without destroying the packaging.

Any suggestions on how to proceed?
