I have had my HP-45 since my days in college (purchased Spring of 1974 I believe). I still use it every day at work. The only problem that I have had over the years, other than batteries, has been with the charger. After several years I seem to develop an intermittent in the cord at the plug where it goes into the charger.
Has this been a common problem or am I just too rough on them? I now have 3 good chargers with bad/intermittent cords. I might consider getting a "bad" charger or two somewhere if possible and changing out the cord(s) but in my experience it is not the charger proper that is the problem but the cord.
Any thoughts?
