RE: DM-15L current draw problem
(12-28-2015 06:35 PM)Katie Wasserman Wrote: I have a DM-15L board -- the one with the bad buttons -- and decided to measure the current draw on it. It's quite low except when a button is held down, then it's 10mA. But even worse is that it's still 10mA when the calculator is turned off! So if you have a button that is being pressed down when the calculator is in a bag, pocket, whatever, you'll deplete the CR2032 in short order.Hm, I wonder if there is a software fix for that. I would assume there are no external pull up/down resistors on the board. So it shouldn't be too difficiult to change the configuration of the internal ones in sleep mode. But maybe the "ON" key isn't treated differently and is an issue? |
