mac battery...is it truth?

[louiscy1]

hey guys...i would like to ask you something...
is it truth that if the mac is on AC with no battery is slower than the mac on ac with battery?

The MacBook can operate at slower speeds to maximize battery life. However, this setting can be changed via System Preferences so that it always runs at full speed.

The same thing applies to most modern Windows notebooks.

To be quite honest, unless you're doing something taxing like video editing, there's usually no need to run at full speed. Even on low power consumption mode, the MacBooks are pretty speedy for normal use.

no have a look here http://discussions.apple.com/thread.jspa?threadID=489707&tstart=0

it says that without the battery the cpu is locked on 1ghz

whats the point of having a macbook if i have to have the batery on all the time

I wouldn't worry about it based on that thread. If it's confirmed by Apple, that's another story. This is the first I've read of this "issue", if it were widespread, I'm sure it would have been reported elsewhere.

I remember reading this somewhere directly on Apple's website. While on AC w/ no battery plugged in, one of the cores are disabled.

Decided to look it up:
Apple

There might be a more detailed explanation somewhere on the Apple site (at least that's what I remembered reading), if someone wants to spend more time looking for it.

Why would you want to not use the battery?? Surely you just keep the battery in and plug it into a socket, then your using AC whilst it is charging?? Or does the battery only last so long so people try not to use the battery when they don't have to??

Please correct me of I am wrong as i do not know

Thanks

if it is like that its a disaster...only one core?
omg...please search with me and lets see whats going on fellas

There are some nut jobs out there that think they can make their battery last forever by tickling it just the right way. What they don't realize is that batteries are consumables with a very finite lifespan. Yes, you can (and should, according to Apple) just leave the battery in the machine - even if you're not running on battery power. By doing that, you negate any need to be concerned with this "flaw" and the battery will last just as long.

You do realize that 99% of the software out there isn't capable of taking advantage of multiple cores? You also realize that this condition is said to only occur when the battery is NOT mounted in its bay and the machine is running from the power adapter alone? Do you really plan to use your machine in this manner? Why wouldn't you just leave the battery in?

This looks like a lot of worry over a marginal issue. I have had a laptop of some sort or another going on 6 years now, my wife has as well, and I don't think we have ever used the comp plugged in without battery. By doing so, you are leaving your battery connection terminals open to dust and/or damage. If you plan on not leaving the battery in, and staying plugged in, then why get a portable computer? With the new power adapter, without the battery, even the slightest nudge, tug or pull, out pops the power connection and there goes all your unsaved work.

you mean that there is an option of leaving the battery plugged in but without charging/disscharging. and if yes that will solve this issue?
And yes i know that most of the software does not use multiple processors but for me which i am a music producer i need maximum power

Yes, all laptops have circuitry that stops charging the battery when it is full. You do not need to worry about removing the battery when you're running on AC (mains) power.

The issue only occurs when people attempt to run their machine with the battery installed.

I am alos puzzled on this whole battery thing: so basically there is no need to ever take the battery out unless you are replacing it? Taking out the battery when using Ac doesn't meen it lasts longer all it means is the risk of loosing unsaved work?? Thanks

Right. Most modern battery-powered devices have circuitry that prevents the battery from overcharging (this includes notebooks, PDAs, cell phones, iPods, you name). Even if you are not using it, the battery should remain installed. One of the benefits of doing this is that if you should ever lose power, you will have battery backup.

Again, there are those that are under the false impression that removing the battery when it is fully charged somehow makes it last longer are misinformed. The only time the battery should be removed is if it needs to be replaced. The only other situation where it may be advantageous to remove it is if you're not going to use the machine for a long time (meaning weeks or months). Then the battery should be drained to about 75% and stored separately.

Ok thankyou very much for the helpful reply. I think i will nominate you for the competition thingy!! Honour of the month or whatever it is, you have been very helpfull thanks.

cwa107 let me get thinks straight. If i have the battery installed and charged and the AC adapter on that means that the battery is not affected? the battery when is full then the adapter will stop overcharging? its is safe for the battery life to leave it always on?
if that is truth u r my savior

Yes, correct.

hhhmmm...sounds good...is there any official anouncment for that?
i am hesitated cause i dont want to make my 100 pounds precius battery crappy

No, that's just the way modern computers are made.
