HP-25 - Wayne Selway - 11-22-2013
I have an HP-25 that displays an "E" when powered up. Any way to fix?
Thank You
Wayne

Well, you need to provide a bit more information, but most likely you've fried a chip in it, so it's essentially unfixable from a practical standpoint. Normally, this occurs from using the AC adapter w/o a good battery inside or poor contact with the battery. Does it respond to the keyboard and if so what are you seeing on the display ? An E by itself means nothing, but it will display Error when an error condition occurs, such as division by zero.
