Only 4 days? That's a massive current leak. The good news is we ruled out the SD card pins as the problem, the bad news is that it doesn't solve the problem.

I've managed to obtain a second-hand HP-50g in decent condition to run newRPL on. I've flashed it and my HP-49g+ with the latest firmware.

The 49g+ power consumption is unchanged from my previous measurements - 4mA when turned off; about 42mA when the calculator is on.

The 50g draws \(29\,\mu\rm A\) when turned off. However, to my great surprise it draws 48 mA when turned on and doing nothing. Is this the expected power consumption? Has the latest firmware caused a problem, or do I have an "odd" machine?
