Hi 41-world out there !
I´m a HP (41)-collector for roundabout 1 year.
I got two CV´s (fullnut) and several peripherals for them.
All is in excellent optical and working condition.
The only problem is : auto shut-down occurs after a mere 30 seconds. For my older brain this is often too fast to finish thinking about the next keystroke. The Handbook tells that i have 10 minutes time until shut-off.
I guessed that there is a certain R/C-circuitry controlling this time and that a capacitor is just fatigue an should be changed. But looking at the schematics i could not identify the appropriate circuitry and the capacitor. Can anyone help me fixing that problem ?
Kind regards
Uli
