Removing the SD card causes the current to jump up to 10 mA. Re-inserting the card causes the current to drop back to 4 mA again, even before the card is properly seated. Simply having the card mostly in without pushing causes the current to drop. I will check power consumption on mine tonight and report. Edit... Here is what I get on a HP-50G with Newrpl hooked to a 6 volts regulated power supply Calculator ON : 42.3 milliAmps Calculator OFF: 21.7 microAmps (2000 times less than ON state) Same values with or without the SD card installed François |
