Macbook performance without the battery

I use the macbook pro for editing video in Final cut pro, and sometimes when I am at home I remove the battery.
and then I choose better performance, but the performance is not so good, i have constantly drop frames warning in the Final Cut.
I've read about that a lot, and most people say that if remove the battery the macbook pro runs in half perfomance.
And my question is,
can I get total perfomace of the Macbook pro connected to the power without the battery, like I have when I got the battery on it???
thanks

> but can you explain me why??
Not fully, some call it a bug others a feature/thermal protection.

Using a MacBook Pro without the Battery?

Hello!
A user in our office left their MacBook Pro (2007, OS 10.6.8) locked up in their desk during a holiday break. When they returned, the battery had swollen enough to force a corner of the access panel open. I removed the battery back and tray to inspect the insides: clean and dry. There appeared to be no leakage. We tried starting it up. The but the screen wouldn't even flicker. It remained black. (I noticed, too late, however, that the user kept holding down the power button when they didn't get what they were expecting from the screen.) The model is a 2007 MacBook Bro with Mac OS 10.6.8
A couple questions:
1) I've never heard of a laptop battery swelling up on its own after lying dormant for two weeks. Is that possible? What are the normal indicators of a failing battery?
2) Is it possible to restart the MacBook without the battery pack and tray inside? What is the best procedure for doing or determining that?
Thanks for any help!

Swelling is a common indicator of a failing battery.

Not always, and even if you can the MBP will run at a lower speed.
Replace the battery and all other components that were removed.

Hi, my MacBook Air is not working anymore if it's not connected with the power cable. It's pretty new so I can't imagine that the battery is dead already. Why can't I use my MacBook Air without the power cable even though I charged it for hours?

Will a mid 2010 15" macbook pro not boot without the battery in it?

I have a 15" mid 2010 mabook pro with a swelled battery. I tried booting it without the battery in it and it would not power on. Is this by design or has my macbook been damaged?

Here are the Apple costs for a replacement battery:
iFixit sells Apple batteries, but the last time I looked, they were out of stock.
Recently on another post, it showed Apple batteries available through Amazon at favorable prices that appeared to be OEM quality. I suspect that these are gray market batteries but they may very well be satisfactory. I still say 'Caveat Emptor'.
If you do choose to go the third party route, you will need a #0 Triwing driver to install the battery.
Ciao.

How do I start my MacBook without the Battery Installed

My battery has started to Bulge and I am having the usual problems I have read about with this issue, the trackpad isn't working, premature shutdown, etc. I am living thousands of miles away from an Apple Store so I have given the battery to a friend to either get replaced or buy a new one. In the mean time I want to use the MBP without the battery. How do you start the MBP without the battery being installed?
I know there will be a reduction in performance but I am not worried about that at the moment as I need some of the info of my hard disk. It can't run any slower than it is at the moment, it's dead.

Kappy Thanks I have started it again. I actually found this thread and tried it yesterday before my question but nothing worked. I left the computer uplugged over night and thought I had nothing to lose so I tried it agian this morning and it actually worked this time. I only had to use the Restart (Control-Command-Power) option not the SMC reset. Leaving the power disconnected must have cleared something somewhere.
Thanks again.

Is it possible to power the macbook pro on just the wall charger, without the battery?

I'd like to be able to not even use the battery on my computer. Is it possible to run it just off of the wall plugin?

I have a late 08 Macbook Uni, I wanted to run it without the battery when I first got it since I got used to running my Dell Laptop without batteries to save my battery from dying because of windows bad power management.
I found out that my macbook runs much slower without the battery. Can't really tell you why it just does.
Do remember that Macbooks have a much better power management system than windows. My Dell Laptop battery didn't even last 3 years before it fully died.
My late 08 Macbook is way over it's 1000 charge cycle ( i'm at 1067 ) and i'm still getting over 3 hours from my original battery.
I suggest you leave your battery in.
Just follow apple's battery care procedure to make your battery last longer - if that's what you're worried about.
good luck

Running without the battery. Bad for the Macbook?

I want to preserve the integrity of my battery, so I am runing my MBP without it in. I just have it plugged into the wall. I'm wondering, is it bad to run it without the battery? Like, are there any huge malfunctions that could happen?
I dont want to constantly run it with the battery, when I have a wall outlet. My brother did that with his powerbook, and ater a year, his battery life sucked.

All batteries lose their ability to recharge to its full factory capacity, Li-ion or not. This is the very nature of rechargeable batteries. Since li-ions don't have a memory footprint, it doesn't matter what you store them at.
You bro read this:
A unique drawback of the Li-ion battery is that its life span is dependent upon aging from time of manufacturing (shelf life) regardless of whether it was charged, and not just on the number of charge/discharge cycles. This drawback is not widely publicized.
At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 degrees Celsius or 77 degrees Fahrenheit, will irreversibly lose approximately 20% capacity per year. However a battery stored inside a poorly ventilated laptop, may be subject to a prolonged exposure to much higher temperatures than 25 °C, which will significantly shorten its life. The capacity loss begins from the time the battery was manufactured, and occurs even when the battery is unused. Different storage temperatures produce different loss results: 6% loss at 0 °C/32 °F, 20% at 25 °C/77 °F, and 35% at 40 °C/104 °F. When stored at 40% charge level, these figures are reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively
The problem is he didn't quite understand it or remember it. Storing the battery at 40% doesn't reduce the 10-20% loss. What the excerpt talks about is temperature of the environment the battery rests in. It is an interaction effect.
If the battery is at 100% charge, and stored at 40 °C/104 °F, then a 35% reduction will occur. If it is stored at 40% capacity, then a 20% reduction will occur. If it is stored at 100% charge at 0 °C/32 °F a 6% reduction will occur, when if the battery is dropped to 40%, only a 4% reduction will occur.
You bro is wrong in thinking you can stop Li-ion batteries from losing their charge. This happens from the point of manufacturing.

Want to reduce your MacBook temperature, remove the battery.

From http://xlr8yourmac.com/
Want to reduce your MacBook temperature, remove the battery.
When we were testing V0.5 of SpeedIt we discover a strange behavior, if we remove the battery of our MacBook the temperature drop because the maximum operational frequency of the CPU become reduce to 1.0 Ghz.
We were investigating more on this, and we found why this happen, the SMC subsystem when battery is not detected, activate the Thermal Trip indicator and the CPU get into Thermal Throttle, reducing the frequency to 1.0 Ghz and minimum voltage.
You will find this and other "hidden features" with the documentation of the upcomming version of SpeedIt.
We decided to published this in advance because a user "no-one" write about this matter on the forums. He is a good tester we'll liek to take him in account . More information on the forums.
Apple Mac Intel SMC Firmware Update
We have been testing the lasted firmware update and the conclusions are:
* The fans run at more revolutions always.
* The Temperature drop more or less between 5 to 10 ºC
* The voltage values of the CPU change.
* The MacBook is cooler but more noise.
* To get into sleep need a minimum of 5 seconds, after
you close your lid.
* Don't put in your bag until you hear that the fan
stop, some times the MacBook don't get into sleep.
More detailed report and data soon.

yeah its pretty ridiculous that an individual pays all that money for a machine that Apple continually trumpet to be better than a PC machine and then it falls down at these niggly little turns.
Other machines, can run at full speed with battery of, no ?
Why is it ridiculous ?
If I use my unit for some hardcore music / video editing sessions, I will take it off the battery so Im not constantly charging / recharging the battery - is that ridiculous ?
Am I going to be pis%£% when my expensive machine, I paid mad dough for is going to perform like a snail as opposed to what it can really - YOU BET !
"Beeing a picky customer is a MUST in this case. I realy don`t understand the people who are trying to protect this company no matter what happens. You HAVE to remember that it is not a privilage for you that you own Mac. It is a privilage FOR Apple that you decided to spend big time money on their products. It is your DUTY to be picky and strict."

I have many of those lost photos on my iPod. How can I import those to my MacBook Pro without the iTunes synchronization kicking in and removing them?

I lost rather a lot of photos on a corrupted external storage device. I have many of those photos on my iPod. How can I import those
photos into my MacBook Pro without the iTunes synchronization function kicking in and effectively deleting those photos I want to
import from that iPod? Any assistance would be greatly appreciated as those photos now only reside on that iPod...

The photos you synced to your iPod through iTunes are no longer in their full resolution, but instead are scaled down thumbnails of those photos. So if you do manage to get them off your iPod, they will be quite small in size compared to the original ones you lost.
In order to get them off of your iPod, you'll need the help of some sort of 3rd party software. Here is one option.

Important!! Improve the life and performance of the battery.

Reduce the operating temperature and increase battery life
The battery in your notebook PC is designed to provide the necessary amount of energy for the processor while maintaining HP high safety standards. As a result, the battery may not charge or may stop providing power to the notebook when the battery temperature exceeds the specified, design safety level.
If the battery life appears shorter than normal, the battery stops charging before it is 99%-100% full and the battery appears warmer than usual, the battery has most likely reached its designed "no charge" safety state. The battery will no longer charge until the temperature condition is corrected.
Try one of the following methods to correct the battery temperature:
When charging the battery, do not use applications that require large amounts of system resources such as graphic or memory intensive applications, heavy and extended hard drive usage.
Turn off your notebook and remove the battery to allow it to return to a safe operating temperature.
Make sure the notebook PC is operating on a hard surface. Using the Notebook PC on a bed or sofa may block the vents causing the notebook PC to heat up and shut down.
By taking these steps, the battery will return to its normal operating temperature range and continue to charge and discharge as designed.
Calibrating the battery while PC not in use
Recalibrating the battery requires a cycle of a complete charge and a complete discharge. To recalibrate the battery while using the PC is not is use complete the following steps.
The recalibration may take 1-5 hours depending on the age of the battery and the configuration of the notebook PC you own. The PC should not be used while you perform the following steps. Completing all the following steps will also calibrate the battery so that the power meter readings are accurate.
Shut down the notebook PC
Connect the AC Adapter to the notebook PC and to an electrical socket.
Charge the Notebook PC until the Battery Charge light is Green. This indicates the battery is completely charged.
Press and release the Power Button to start the computer.
Press the F8 key several times when the HP Logo displays.
When the Windows Advanced Startup Menu displays, select the Startup in Safe Mode option.
Remove the AC power adapter from the notebook PC.
Allow the battery to discharge completely until the notebook PC turns off.
The battery is now calibrated and the battery level reading on the power meter is now accurate.
If you are not using the notebook regularly then please unplug the AC adapter and shut down the notebook. By following these practices will improve the life and performance of the battery. Here is a quick list of Do's and Don'ts for the care of your Li-On batteries:
Do's
When you receive a new Notebook or Tablet PC, leave the battery to fully charge overnight.
Condition a new battery by using it until it is fully discharged, and then re-charge it fully. Doing this once a month will help to accurately calibrate your battery.
Always ensure the battery is recharged as soon as possible after it becomes fully discharged. A battery will be permanently damaged if left for an extended length of time in a fully discharged state.
Remember that a Lithium-Ion battery will slowly deteriorate; a new battery will always perform better than one that is 6-months old.
Remember that the battery half-life is rated for a certain total number of charge/discharge cycles (see your User Manual or Quick Start Guide for the rating). For example, a battery that is rated for 3 hours and 500 charge/discharge cycles, will still be considered as within specification, even if it only lasts for 1 hour 45 minutes after 500 charge/discharge cycles.
Heat is the worst enemy of a battery. Allow plenty of air to circulate around the Notebook/Tablet PC, so that the battery is kept as cool as possible when charging and also when in use. If provided, use the integrated 'legs' under the Notebook to raise the notebook and improve air circulation.
Remove the battery if storing for several months (the battery should be at approximately 50% charge or higher).
If you use a NoteBus or if charging your Notebooks or Tablet PCs in a confined space, allow for adequate ventilation in order to keep the batteries as cool as possible.
Don'ts
Do Not - Expose the battery to excessive heat or cold (i.e. outside the range of 10-35 degrees Centigrade ambient).
Do Not - Store the battery in a fully charged state (store batteries with about 50% charge).
Do Not - Allow a nearly flat battery to be unused for more than a month or so. The battery will slowly discharge until it becomes fully discharged and this will permanently damage the battery cells.
Do Not - Charge your Notebook/Tablet PC inside a carry case - the battery may overheat.
Do Not - Charge your Notebook/Tablet PC when stacked on top of each other - the battery may overheat.
Remember: Your battery is slowly degrading all the time, even if it is not used. Keeping your battery as cool as possible will slow down this degradation considerably.

MIFI4620LE Jetpack blinking amber light--does this mean the battery is bad? Should the unit operate without the battery installed if plugged in?

MIFI4620LE Jetpack blinking amber light--does this mean the battery is bad? Should the unit operate without the battery installed if plugged in?

The MIFI4620LE Jetpack does not work without a battery installed, even when connected to an external power supply.
I personally think that was a dumb design. I would think the unit would use more electricity when continually charging the battery than just powering the unit it's self, but that's the way Novatel made them.
If your Jetpack works with the battery installed and connected to an external power supply, but does not power on with power supply disconnected, I would say that the battery is defective or worn out.
You should be able to go to a nearby Verizon Store and have them either test the battery or put a new one in it to see if it works. Then you will know if you need to spend the $$ for a new battery. OR if you always use your Jetpack at home, or in your car, just use the old battery connect to a power supply or your cigarette lighter and save the cash.
As the Customer Support person stated, the slow blinking amber light is a normal state when the Jetpack is turned on and connected to Verizon's service.
I hope this solves your problem.

Is it a good idea to use the A/C adapter without the battery installed?

Hi everyone!
I have a question. When using my iBook, is it a good idea or is it adviceable to power my iBook using the A/C adapter only, without the battery installed - for the purpose of preserving my battery? I tend to use my iBook heavily and as a desktop computer replacement.
My iBook is a G4 1.33 Ghz 12" model running OS X Version 10.4.10 and my peripherals are optical mouse, keyboard, powered speakers and an external hard drive.
Thanks.
iBook G4 Mac OS X (10.4.10)

Well the service manual says:
"Warning: Never turn on the computer unless all of its internal parts are in place and it is fully reassembled. Operating the missing parts can damage the computer or cause injury."
Without a battery in place the battery connector would be exposed and things always find their way into the opening. I've heard of people keeping a bad battery in place just for that reason. Also if you keep it plugged in all the time it won't lose it's date/time.
If you check "set Date & Time automatically" in the "Date & Time" system preferences the iBook will automatically reset the time if you have a internet connection.

MacBook pro (late 2008) shutting down even without the battery

Hello
I have a MacBook pro late 2008 model, recently it started to randomly shut down.
I have tried the following
- Reseting Pram
- Reseting the SMC
- Recalibrating the battery
- New hard drive
- Returned to original RAM (from 4 to 2Gb)
- Removed the battery and run with the MagSafe only
- Downloaded a fan control program to run it at max and verify if this was not a heating issue (although this also happens right after starting the laptop)
Does anyone have any suggestions? I'm already loosing hope on my Mac :(
Thanks for any help that you could provide

Hi V,
Even though the symptoms don't match up exactly, you may have the NVIDIA issue. First, go to System Profiler > Hardware > Graphics/Displays and see if you have the GeForce 8600M GT GPU. This is the GPU covered under the free repair program. While there, also look at PCIe Lane Width. If it says anything other than x16, the GPU has issues (but this is only one potential symptom). If you have the 8600 GPU, bring the MBP to an Apple Store or AASP for free testing. If Apple's free test confirms the issue, repair is free. Read all about it here: http://support.apple.com/kb/TS2377
Also, whether you have the 8600 or not, you should run all the updates in Software Update.

Plug in the macbook will affect the battery life ?

is it true that it's not recommended to keep my macbook plugged in all the time while I'm using it ? will that help or kill the battery ?

I believe this is incorrect. On Macs with non-removeable batteries, keeping it plugged in will not affect battery life/performance as long as you run it on battery 1-2 times per month to around 40%.
