I got my DM42 in February, and it worked great. It's been in a box (off, of course) for March and April while I moved my office, and I just checked it out again. The calculator would not power up without USB attached. With USB, it operated just fine.
I removed the battery, which read near 0V. I placed a new good CR2032, which read 3.1V, but still no activity when I press ON. I tried resetting the calc via the reset button, but nothing. Again, the calc works when USB is attached.
Has anyone seen this before? Is there a simple fix?
If you're having problems with the hardware of a DM42, post about them here.
