I've reflashed the calculator to HP ROM 2.15; current consumption when off is 18 microamps and about 11mA when on and not doing anything. These numbers seem normal.

However, reflashing to the latest version of newRPL gives me a current consumption when turned on of about 40 mA, and a current consumption when turned off of either 4 mA (SD card in slot) or 10 mA (SD card not in slot).

On my HP50g also running newRPL current consumption is about 24 microamps when off; when turned on, the current is between 40 mA and 50 mA.

I double checked that newRPL is following the recommended practice when it comes to pins in sleep mode. There was no more progress in that regards, so there's no reason to expect any different measurements.
