HP 31E and 33C won't power up - dmh - 02-22-2021 11:19 PM Hi, I have a 31E and a 33C that appear in very good condition with no visible corrosion, however, they show no signs of life with new batteries in them. Any tips or pointers to articles on what to look for and check to try and get these going again when I open them up? TIA, dmh |
