HP 35 - Working with AC Charger but not Battery Pack

[teenix]

Definitely bend the two fingers outward a bit to increase the contact pressure. I have had to do this in the past. It is possible that the charger was connected for a long period of time or had many charges in the 50 or so years of its life and compressed these inward.

If it goes loose again after periods of charging, then the metal may be fatigued, and a replacement might be in order.

cheers
