  1. A few things to look at: The real-time clock runs off the battery, not the main regulator. That always stays on, unless you remove the batteries and leave it long enough for the storage capacitor for the clock to drain (5 minutes-ish) There are three turn-on sources for the main regulator. One is the processor (which is how it stays on) one is the fire button (how it turns on normally if it is off) and one is the USB. So USB should always wake it. The fire button turn-on is capacitively coupled (as it is on some other DNAs) so that if your button gets stuck down in some luggage or otherwise it don't force it to stay on and drain the battery. But that means that the processor has to wake up and take over the job of keeping it on fairly promptly, or it'll turn back off. Likely there's something going on in the firmware that occasionally delays the boot long enough to miss the turn-on pulse. The board does a number of self-checks at power-on, and one may be taking too long depending on the state of whatever it is checking. If you run into this, can you post up your manufacture date for the board, your serial number, your firmware revision, your number of cells and the approximate state of charge of your batteries? I'm reasonably certain I can get to the bottom of it with sufficient information. Thanks! John
  2. Download your theme into theme designer, go to the "Screens" tab, select the screen you want to modify from the list of screens on the right. (Probably the main screen) Left click on the wattage field that you want to change the increment of. Then from the fields on the right of the screen, find Source: Coil Power. Below that is a button labelled "Options" Click that and an Options form pops up. There, change "Step Size" from 1 to 5. Save your theme if necessary, then upload it onto the device. Hope that helps John
  3. When I hand-tuned thermal parameters, I got 20 degrees F per amp and a 12 degree offset. Try those values and see what you get. We'll have a new firmware in a few days, finishing up the Mac version right now.
  4. If you had a settings file with appropriate settings, then you wouldn't need to run case analyzer yourself - the results should be fairly consistent. If you load on Jasonvallamil's settings (from the downloads section) that should get you pretty close.
