You should leave the battery in the laptop even when plugged in power. This will insure your system maintains proper charge for the battery when you need it. Also leaving it in will not harm the laptop it was made to have a battery in there to start with. And if others tell you about battery memory taking it out and in would do more to reduce or make you battery more pron to battery memory. Leave it in as you never know you will pull the power plug and there goes your games.

HT3053 Can I run my MacBook Pro Late 2008 without battery forever? Is it bad in long term or anything? Does it make the system less stable?

Can I run my MacBook Pro Late 2008 without battery forever? Is it bad in long term or anything? Does it make the system less stable?
My battery got swollen (and I unfortunately noticed it very late and might have be running with it for months, which potentially explains all the crashes everyday and the trackpad not working anymore, the Apple test also says I have a bar of ram broken...) and I had to remove it because the back pannel did not close anymore... Can I still use my MBP normally forever that way? I was planning on buying a new mac anyway but maybe waiting for the next iMac upgrade in the year... Should I wait?

Other than the system shutting down instantly if you have a power outage, whcih could corrupt the OS. Nothing else bad will happen.

Macbook Pro 2009 doesn't turn on without battery

Hi. I have a mbp mid 15" mid 2009 2.66. In time the battery bacame very low like 4% health, and now is completely dead or broken. When i check the battery status leds it shows full and when I try to turn on the computer (of course with AC power) it tries to turn on for 1 sec then it dies, even with AC plug. i hear the fans trying to spin for 1 sec or less, i hear the hdd sound and i see the standby led like it is trying to power on normally but It seems like it's trying to use the battery to power on. (Even when the battery was good, it would't turn on if it was 0%.. i would have to wait 10-20min or whatever to charge it to aprox20% or whatever).
I can't buy a new battery right now so I tried to turn it on without battery (I am sure the battery is completely dead and if I put a new battery it will work for sure) but why it doesn't turn on without battery?? I don't believe it needs battery to run on AC power. It's a SMC thing. What can i do to use the SMC and run the computer wihout battery? Now I'm using it with SMC bypass (keep pushing power for 10 sec and plug the ac chord) but with SMC bybass the fans run at max speed, no keyboard backlight no sensors and all that uses smc its not working. Is it safe to use it that way? (it's not running slower, i don't have performance issues).
I tried PRAM reset SMC reset, removing battery with AC on.. nothing works. It won't turn on without battery. Only with smc bybass.
It is something i can do? or buying a new battery is the only solution?
Thanks.

You have a hardware problem. More than likely it is the cable that goes from the logic board to the display. It sounds like an internmitent short. Works sometimes not at other times.
The only way to fix a hardware problem is to replace the faulty piece of hardware and the only people that do that is either an Apple store or an Apple authorized repair center. That is unless you can diagnose the actual failed hardware part, find one from an Aftermarket Mac parts seller and replace the part yourself.

For starting macbook without battery, is there any option in OS??

Hi
Unfortunately i m not able to start my macbook without battery.
My question is that is there any option in operating system which i suppose to on for this or it doesn't required any OS interaction!!??

Your MacBook will reduce the processor speed while it is operated with the battery out of it. See Mac Support article http://support.apple.com/kb/HT2332 and http://www.gearlog.com/2008/11/applenotebooks_take_hugeperf.php

X230 CPU performance issue on AC power without battery

Dear Lenovo & Community Members,
I've recently received my X230 (model no.: 2320-24B), and discovered an issue related to the CPU performance of X230 on AC power. To make the long story short, my X230 is not running at full performance on AC power with battery detached. Accordingly, the X230 was shipped with setting at "Maximum Performance" under "Intel Speed Step" in BIOS by default on AC power.
Full Story:
My notebook is X230 (model 2320-24B) which comes with Ivy Bridge i7-3520M. I have a habit to detach the battery when it was fully charged, as I want to reduce the battery aging and my job does not always require me to work on the go. And by accident, I've discovered that X230 performs differently on AC power with and without battery. To be more precise, when my X230 runs on AC power with battery detached, it runs as slow as my Sandy Bridge i3-2100 desktop, which sounds very weird to me for a notebook costing me more than $1000.
Accordingly, I've benchmarked my X230 and here are the results, both with BIOS setting to "Maximum Performance" under AC Power:
AC power, without battery - WEI CPU Score: 4.9, WinRAR 4.2 benchmark: ~1,900kb/s, CPU @ 1.189Ghz on load
AC power, with battery - WEI CPU Score: 7.2, WinRAR 4.2 benchmark: ~4,000kb/s, CPU @ 3.6GHz on load
On battery power - WEI CPU: 7.2, WinRAR 4.2 benchmark: ~4,000kb/s, CPU @ 3.6GHz on load
Based on my tests, I’ve found that X230 is only performing at maximum performance when attached with its battery, and it is underperforming at its lowest clock speed when not being attached with the battery.
Conclusion:
I would like to ask if other owners of X230 in this community have the same problem (and are able to repeat my findings). I'm quite disappointed to find that my X230 is running even slower than my i3-2100 desktop, and it simply doesn't make sense for a notebook with removable battery yet unable to run at full performance without battery. I demand Lenovo to address this issue.

Edit: I'm already running the latest BIOS 1.12
Solved!

Hi slkong, welcome to the forum,
allow me to assume that you have the 65W AC power supply. If this is the case in order to reach full CPU performance you do need to have the battery attached, there are several threads on this within the boards concerning different systems and also this Knowledgebase article.
Hope this explains the situation for you.

Could macbook starts without battery by using adapter as power source!!??

Hi all
I have macbook black early 2008 model. My battery is damaged as it falls in water.
I have experienced that If the adapter is plugged with macbook and macbook is on and then i remove the battery ...its remain on...
My question is this that could macbook starts without battery using the power adapter as power source.
Thanks
Regards
Abdul Azeez

Yes it will start and run. The downside is your MacBook will run slower and if you accidentally pull out the plug it will shut off immediately and you'll lose any work that hasn't been saved. I suggest replacing the battery when you can.

Whine Present With and Without Battery

My whine occurs with or without using the battery.
Also, I run Photobooth and the whine disappears. However, as soon as I close Photobooth, it comes back.
It seems like my whine is more prevalent than other people's....
Anyone else experiencing this?
Mine is week 12

All cpu whines occur with and without battery, but with the AC adapter plugged in, its not as bad as with the battery. Before you close Photo Booth click on a still picture at the botton then quit Photo Boot and your whine will go away. Also the week # of your MBP has nothing to do with whether or not you have the whine.. maybe in the future it will determine if you have it or not but thats not the case so far.

It's possible work with ZEN Micro 6Gb without battery

I would like to use the ZEN micro 6 Gb without battery, only plugged with the power adaptor ... it's possible?
Thanks a lot

Thanks <SPAN>Cat ,
I have a friend with ZEN 5 GB and tell me the same (like Muvo2) ... it's extrange because my generic power adapter charges the battery correctly, but when i remove the battery and try to work directly with the power adaptor don't work.
Please, I don't know if my problem it's my generic power adaptor ... anyboy have the ZEN Micro 6 Gb and can work with the player removing the battery and plugged it with the Creative ZEN Micro original power adaptor (not included with the product)?
Thanks

My laptop won't start without battery mounted

Hello! I have a Compaq CQ61-200sq laptop and recently my battery just got "old". So for the time untill i will buy a new one a just took it out and try to use the laptop without battery, just with the AC adaptor pluged in. But, just i said it won't start if i don't mount the battery. If i took the battery out while it's on there is no problem.
So, my question, beside what could be the problem, is if the problem will disapear with a new battery. I don't want to buy a new battery and still have problems.
Thank you!

I updated it about two to three times and would still experience the same problem.
Why update 3 times?!? If you run an update, and it installs normally, that it - done!
There's a world of difference between running BatteryUpdate 1.2 and installing a new battery. In fact, if you read the linked page above, it states that the after you run battery update if you experience any of the listed problems you should contact AppleCare. Their first step will be to replace the battery. Could it be a logic board problem? Sure. Is that the first thing they'll do? No. By that reasoning, the first thing to try if your car fails to start on a cold morning is to put in a new engine...
So, to the OP, contact Apple - or better yet, if it's convenient, go in to an Apple Store. Get a new battery. If the problem persists, go from there. The advantage of taking it into a Store is that they'll test it on the spot.

My ipod touch was put to load without battery but it does not appear is loading or not What do I do?

my ipod touch was put to load without battery but it does not appear is loading or not What do I do?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

MBP performance with and without battery attached while plugged in

Hello all, I read somewhere that, even when plugged in, your MBP draws power from the batteries for performance. And I notice this when I try to use my MBP with the battery removed, which leads to lag and stutter.
So, my question is, does this happen while running windows on your MBP too?

Well, I do have an aluminum cooler with 2x60mm fans blowing quite a lot of air into the underside of the MBP. The cooler reduces the temp of the MBP about 5 degrees celcius with the battery, but without the battery, the cooler reduces the temp by about 10. Under load, the temperature differences become greater. I don't know if the greater temp difference without battery this is due to underclocking of the CPU, or just removal of the battery leading to less insulating material. And of the times I've runned Windows without a battery, there has been no shutdowns or BSODs, and I haven't noticed any change in performance.
Guess I should take the confound (cooler) out of the equation and see if performance changes with/without battery.
BTW, CPU-Z shows no change in clock speeds with or without battery in Windows.
Oh, and is there any way to see if my 8600GT is defective or not?

Macbook Pro will not power on without battery installed

Hi there,
I have a Macbook Pro A1226 that fails to power on without a battery installed.
i.e. will not run off AC power on its own. I have tried 2 other power adapters, no change. All 3 adapters are outputting the correct voltage without fluctuations.
But, if I am in OSX with a battery plugged in, shutdown the laptop, remove the battery while AC is still plugged in, it will power back on without any issues. But as soon as I remove the battery, it will not power back on using just AC.
Is this an I/O board issue, or a mainboard?
I have power drained the unit and reset the parameter ram.
Thanks

Any update on this? This is the same thing that's going on with my laptop right now. I was at the Genius Bar and they said they can send it in for repair. Takes 7-9 days and costs a minimum of $310. At the time I was there, my computer wouldn't start up at all, because the battery had drained to less than 20%. It didn't even start with just the power cord (no battery in). The "genius" finally got it to work by doing a PRAM and SMC reset. Got home and was able to recharge my battery to 100%. Used my computer for 2 days before I dared to take it off the power supply. Lo and behold, as soon as I take it off the power cord, then re-connect it, it shows "Not Charging". I tried to do SMC again, but no luck. Keeps saying "not charging". Even tried with a brand new battery. Do I have to get the I/O board thingy replaced?

MacBook Unibody Aluminium 13.3" (late 2008) turns on only sometimes -without battery-

Last week, I removed the battery from my MacBook because it was time to replace it (the first time since I bought it). When I did it and I tried to turn the computer on without the battery, it didn't work. The same day, I made a SMC reset but it didn't work either since the Mac didn't turn on. Two days after, I tried to turn the Mac on and it surprisingly worked! The computer worked normally and I performed a hard disk and a RAM analysis to determine whether there was a problem or not. The analyses showed no damage. I turned the Mac off and the next day it didn't worked again. Two days later again, it turned on and worked normally. I've got now the new battery but I don't want to place it and take the risk of damaging it without knowing firstly why this happened. What should I do now? Help, please!

thnx

Okay to use MacBook Pro without battery?

Now I fully understand that it is not such a great idea but I wanted to get some opinions: It's my third NuPower battery. All of them have lasted less than a year and failed pretty bad. This one started bulging quite bad and then I couldn't use the trackpad click button anymore (because it was putting pressure on the trackpad / button.) I took it out and the battery started expanding even outside the laptop! I don't consider myself a rough user. I do occasionally reccaliberate the battery per Apple, make sure I raise the laptop off the table etc. to let air pass under. Currently I am overseas and many Apple resellers do not carry the battery in stock. So I have ordered the battery from Amazon. In the mean time, I am using the MacBook Pro directly hooked up to the 240V outlet with the Apple supplied adapter.
I have heard a few people do this in emergencies. But what say you?! Unlike the US 120V, it's 240 Volts here in India! Somehow I felt better with the battery being there to absorb the jolts! but I have had no issues so far - two days. The Mac wakes up, runs, sleeps fine without a hiccup! I am taking extra care not to trip the extra-easy MagSafe adapter
Has anyone done this? Any direct adverse effects caused by running it straight from the outlet without the battery?

Using iBook G3 without battery - power adapter only

I would like to use my iBook G3 without the battery - just with the power adapter plugged in. I've tried starting up with the power plugged in and the battery removed, and no luck. Removing the battery with the power plugged in shuts down the computer.
I have an old battery that doesn't hold charge anymore and needs replacing. I use this computer from home 99.9% of the time and I'd rather not have a hot battery on my lap. Any thoughts or suggestions? I KNOW it's possible to do this as I've always seen demo models in stores set up this way. I have a relatively new adapter - the one that looks like an airport, not like a flying saucer.

Theoretically, it should work, yes. Have you tried resetting the PMU?
However, I strongly recommend against running with no battery for a couple of reasons.
First of all, even a mostly dead battery usually will hold enough of a charge to save your projects you're working on if the iBook is accidentally unplugged.
Next, if Apple had really intended using the iBook this way, they would have provided a battery hatch cover. As it is, using the iBook with no battery in place would subject the terminals to dust, lint, and debris. Needless to say, this is not good.
Apple has never really called its portables "laptops." They are not designed to run on your lap, but on a hard surface. I know most of us use them on our laps, but these days, I use one of these, which my son bought me for Mother's Day. I use it folded in half, and use the foot to prop up the back so that my iBook is kept cooler than it would be otherwise. It works great.
If the heat bothers you, it probably bothers your iBook, too. You may want to look into a similar solution. One long-time Apple user has suggested an inexpensive acrylic cutting board as a lap desk, and that would work fine, too. I don't recommend running without the battery, though, even if you could manage to do it.
