This is my first mac and I was wondering if it's ok to leave it on all the time plugged in?

I usually do this to my PC when I go to bed, just leave it on with it plugged in.

Alternatively, do most of you just put it to sleep and leave it plugged in? That's what I see a lot of members here do, but I don't know if you guys still have it plugged to the power supply.

Thanks, I know I'm being anal :cool:, but it's my first mac :D.

I leave it on, but sleeping. The recent security update brough to an end my new uptime record of over 31 days.

The best thing for you to do with a battery is to use it, the electrons "stagnate" if not used. I plug mine in when I
m using it at my desk with keyboard, mouse, speakers etc attatched. When I want to use it elsewhere I use the battery. If I need extra grunt, I plug it in.

I hope you have calibrated your iBook battery according to the instructions in the manual. Also, download an app called coconutBattery, it will give you a good idea of how your battery is going. For reference, my 12" iBook is 13 months old, has gone through 96 load cycles and the capacity is 98% of the original 4400 mAh.

I'd go with plugged in and sleeping too, just because it won't stay warm/hot all night. Mostly it should fall asleep by itself even if you leave it on, although mine won't if Adium is connected to an IM server because it stays active.

But anyway, the computer is designed to not charge the battery unless it falls to 95% of full charge. So when the battery is charged up and the computer is plugged in, there shouldn't really be any negative impact on battery life to leave it on or asleep. :)

What the heck? My iBook's 4 months old and has 42 load cycles and is at 94% capacity. Is this because of my high load cycles?

Think of the planet!

If you're not using it, turn the damn thing off! It's like leaving a device on standby - it eats up current. That has to come from somewhere, and in most cases, that somewhere will make the earth a tiny bit warmer. Do your bit and turn it off!

Use it

The best way to keep your battery happy is to use it. Plus who doesn't love using their Mac, I don't know if I've ever left it off for a whole day...

15 months, 327 load cycles, 4059 of 4400.... not too shabby.

It's not about "electrons" stagnating - there aren't any electrons being stored in a battery, except inasmuch as there's atoms that make up the battery and of course there's electrons there. It has to do with the chemical properties of Lithium-Ion batteries, which are best stored long-term at about 40%.

My iBook is very rarely off. I use it every day, so, each night when I go to bed, I sleep it. It's easier to get moving the next day when I need to use it, and the iBooks are designed to be left on all the time (in sleep mode when you are not using it). To give the display a rest (and prolong its life), sleep the machine and you'll be fine. If you are not using it for several days, you should shut it down. Someone else can answer this question: If you are not using it for a few days, and you shut it down, should the battery be removed? I've heard that it should if you are shutting down for weeks or months, but what about for a few days? Can you leave the battery in there and be OK in terms of battery life? My guess is yes, but someone else might have more information. I never fail to use it for that long, so I don't worry about it.

Yikes. Mine is 2 months old and is at 96% of it's original 4500 mAh...37 load cycles. Must...retain...charge.

I'm paranoid I guess.

Edit #2: Ok, now CoconutBattery says 98%; I guess it's a fluctuating statistic.

The purpose of having a 12" iBook is because I take it places, etc. This means I probably turn off/reboot 5 times /day. I mean, if you can seriously leave it on 24/7...you should probably get a desktop.

Why don't you just put it to sleep?

When I'm taking my iBook somewhere, I always just close the lid, thereby putting it to sleep, unplug the power and put the second skin on it. Ready to go! :)

Never had any problems with that. Even managed to slip and fall, landing on the iBook (in the backpack), twice :)o), and it's still going strong...

IDK, it takes a max of 30 seconds to boot, and sometimes I live it in the car in the cold/hot weather and just feel better when it's off. It just seems pointless to have it sleep for a 1 hour car ride when it could be OFF using 0% battery power. UNLESS...I have windows open that I need to keep that way until I finish what I'm doing. In that case, I would sleep it.

i usually have mine sleeping as well

waking from sleep is easier on the hard drive and the battery when compared to a cold boot

Well said that man. But don't forget that Bush is too stupid to ratify the Kyoto agreement. So lots of Americans still think its ok to leave all their electrical stuff on standby.
The sad thing is that I suspect that the majority of Brits do too though.

Generally I agree. I don't know how effective it would be for a notebook however, unless you also physically pull out the power cord from the wall socket. Those external power supplies are still warm even when the machine is turned off, suggesting they still pull current.

I am pleased that my Mini is quite a green computer, however ;)

Where I live it can go down to -25-30C. I commute on the bus. When my ibook is going to be out with me walking and bus waiting, I do turn it off. Otherwise I sleep it/rebooting only after running Onyx or update.
