Re: plugging in the power lead - does it matter?
I read that one should always plug in the power brick before connecting power lead to the Book. If I move it from one place to another, I am conscientiously unplugging it and re plugging it in correct sequence rather than just carrying it with the power lead and brick connected and then replugging the plug into the wall while still connected. I just want to check out if this is over paranoid behaviour or not? I mean the manual suggests not to move the Powerbook while on but people do - but carefully - right? I know that the 5XX series powerbooks were very particular about not being plugged into an unplugged adapter. This was one of the first (perhaps the first?) powerbook with the intelligent battery controller. Apparently plugging a 520 into an unplugged adapter would likely confuse the battery controller. Perhaps this is where the admonition against unplugging the adapter from the wall first came from? I'm not sure if the later powerbooks are as sensitive. On the other hand the power jack on the powerbook is subject to mechanical failure after some number of plug/unplug cycles so leaving the adapter plugged in when you move the computer may risk corrupting the powermanager but spare the power jack.

One thing my T41 laptop does have that the powerbook I own doesn't is drop protection for the hard drive so if I ever did drop the powerbook while it was on I may loose data but that's all backed up anyway. So it is paranoid but with a very real touch of reality to suggest not carrying it around powered up. If its asleep it should be really safe though. -- G-Books is sponsored by http://lowendmac.com/ and...

[EMAIL PROTECTED] said recently: I read that one should always plug in the power brick before connecting power lead to the Book. I've never heard of that. But I can see where it would make sense: The brick is a power sink, that could suck a bit off the battery before you power it up. I think the potential issue is that the power adaptor take some moments of time to stabilise it output (?) I skimmed a whole load of www.macintouch.com Powerbook reports and I think it was in there. I bet most folk just plug it any how - but then I read of System admins at schools etc commenting on the high failure rates of the power adaptors and wonder how important it really is. Thought I'd sound out and find either some tech info or user accounts of problems etc all the best Brian -- G-Books is sponsored by http://lowendmac.com/ and...

Re: plugging in the power lead - does it matter?
Hi Brian, I run the maintenance department for a health care facility and work on a lot of computerized equipment. In almost every maintenance publication for equipment with external power supplies, the guidance is to connect the brick to the equipment and then to the AC service. The logic is that plugging an energized connector into the equipment =could= (=could=, mind you) cause a small arc sending a voltage spike through the equipment. A small possibility, but not one that I want to risk. Now then... I've done it both ways and never had a problem, but when I have choice, the AC is connected last.

A small possibility, but not one that I want to risk. found this at the MacInTouch site http://www.macintouch.com/readerreports/powerbookg4/topic2821.html Mar. 22, 2005 Sterett Prevost The first time I encountered the Apple recommendation to power the external AC adapter first before connecting to the Apple laptop was in the Apple-supplied PowerBook certification training materials prior to my Prometric certification exam. The topic was addressed in one of the test questions, so I assumed it was an important issue. The training materials suggested that the main problem was the onboard power management unit (PMU) which might eventually get corrupted to the point of no longer correctly managing the recharging of the main battery (leading to a main battery that runs flat). Leaving the power adapter connected, but removed from the wall socket, was supposed to lead to PMU confusion as to whether it should keep attempting to charge or not. Using the PMU reset procedure contained in the appropriate service manual was supposed to fix the situation. The reset procedure for all Apple laptops is now covered in Apple Support documents 14449 and 58416. The suggestion about allowing the power adapter to settle down before connecting also makes sense... Sam Elowitch I have read with interest the exchanges regarding plugging a laptop's AC adapter to the wall outlet first, then connecting it to the laptop. I think I'm satisfied that this is the right way to go; now for the next logical question: What about when it's time to turn the laptop off or to begin using battery power? Should you disconnect the AC from the laptop first and then the outlet, or from the outlet first and then the laptop?
