I don't have any documentation relating to the trickle charge theory, but I do have a personal experience with it.
My mom turned off the power strip every night that her Performa 6300 was connected to. She was needing a PRAM battery every year until I convinced her not to do that. Her last PRAM battery has lasted at least 3 years, so I am convinced there is a trickle charge.
Not a trickle charge but a supply to run the clock and PRAM and anything else. It does keep the battery from running down as much.

As a general rule, you should always unplug any computer before inserting a new card. It's more critical on some machines than on others, but leaving it plugged in is inviting possibly shorting out both the card and the motherboard if your hand slips and something touches where it shouldn't. Not to mention the possibility of your getting a shock.
As far as the trickle voltage you refer to, to the best of my knowledge, that serves to allow the computer to respond to the keyboard power switch, and doesn't have anything to do with the pram.

-------------- Original message ---------------------- From: pyoung <[EMAIL PROTECTED]>Hi, Is there any benefit to keeping a computer plugged into a live circuit as opposed to having it plugged into a power strip which is turned off when not in use? I thought I read somewhere that on the 8100 one needed to unplug the AC before inserting nubus cards because of some trickle voltage that is always present when the computer is plugged in. Could this trickle voltage also be supplementing the battery voltage as a way to preserve pram settings and that having the computer disconnected from the mains power supply actually reduces the life of the battery?
