@th3_glove20,
I keep the AC plugged in most of the time unless I'm on the go; but as to your question I might not be the right person to answer it cause my system's usually on

or coconutBattery..

yea usually it will b on after working hrs...till midnight b4 i sleep ill switch it on, so my question is should we leave it on??

mmm seems like the battery will not b charged unless it is below a certain level. i unplugged in put it back at 95%...its not charging. jz like last time when it was 98%

instead, it will start to drop a bit by bit... :|

is this normal ?

yes its correct. Do get your info from www.apple.com/batteries

my experience is that it will re-charge only from 85% or thereabouts...

when u say fast, how fast ? from the screenshot, everything looks alright.

Erm, I don't really understand.
So is that ok to plug in AC charge whenever i switch on the macbook?

recently i used the MB under battery until 10% oni i plug in AC. >.<
is that the wrong method?

it's okay

if everytime u wait until under 10% only charge, sure it wont damage the battery or anything, but u're using a lot of cycles there. the more cycles, the shorter the time the battery can power ur notebook. so u gonna have to replace the battery earlier than u should.

dont be too scared about the battery lah. if got power outlet, use it. also consider the fact that ur macbook is actually slightly slower when running on battery power....u paid for that fast processor so let it perform how it should

I just msg-ed wei and ask for his opinion.
He advised me to switch on my AC first then only turn on MB.
I will just follow his advise then. hehe.

hi, just bought my first macbook white 2 days ago. apple claims that the battery life can last for 7 hours, but in my experience, my battery only last for max 5 hours... is this normal? or i should bring my mb for checking?

thanks:)

it is perfectly fine (in fact recommended) to connect ur laptop to the ac power the whole time. the more u discharge and charge it will increase the cycle count and this is what determines ur battery life. if im not mistaken by the 300th cycle ur battery should be able to retain about 80% of its initial capacity. for me id immediately change my power source to ac once the battery goes below 60% and when im at home ill connect it to ac power 24/7. i do the callibration every 1 month.

Actually not only charge cycle determine the battery life. Soon after the battery left the factory it's life is decreasing. So no battery will last forever (at the moment). It's just a matter when will it happen.

Having a good practice on usage will prolong the life. For all new MacBooks, the battery is internal and meaning it's connected whole time so discharge happen even you are not using the Mac.

I'm happy if the battery lasted 3 years. Else I got ACPP.

off wifi, off bluetooth, put on lowest brightness n dont run anything .

do u mean, shut down the mb? lol

if shut down, 1 year also battery can tahan. haha. i meant juz dont run any apps, n see how long is the estimated time until the battery dies

40 cycles



running on battery btw. is this shit accurate ? i mean coconut battery.

Does this mean that my macbook white's battery is dead? In fact when I turned around the macbook and try to press the battery light indicator, there is no sign of light coming of.

If it's dead, and if I don't have ACPP, what can I do? Can I call Apple and ask for servicing? If in this case, approximately how much will they charge for it?

Thanks in advance for any help.

can u try to find some1 who has a macbook white as well? not the unibody model of course. borrow their battery n see if it works. also ask them to use ur battery too.

try to determine whether if ur battery is dead, or ur battery compartment got problem or not.
