Should Remove Macbook Pro 17 Battery When Using AC
Feb 18, 2012
The owners' manual does not address this issue. I have an early 2008 model MB166LL/A with the easily removed battery. I normally use my laptop plugged in with the AC adaptor, but at least once a week I use the battery, usually discharging it until the last warning pops up before it goes dead. I only got 242 cycles out of the second battery purchased at and installed by the nearest Apple authorized repair shop about 18 months ago (to replace my first expanded/bulging battery about 18 months after purchase).The second battery is also expanding/bulging and the laptop is shutting down unexpectedly. Battery life indicator shows 2 1/2 hours of life at 99% charge & drop-down states "Service Battery". I have ordered a new battery from Laptop Battery One for $69 to replace myself
I understand battery longevity will vary greatly with usage. I watch no DVDs, play no music, and no games, and use most of the battery saving tips. I do notice the bottom of the case heating up from time to time, but I usually always place it on a hard surface so the bumpers keep the bottom up to allow air circulation. Is 242 cycles awfully low for a battery (online claims state 400-800 cycles)? Should I remove my new battery when using AC?

I am looking for a screwdriver or a bit that works to remove the battery in a mid-09 15" Macbook Pro. Instead of the typical tri-wing that Apple has used in the past, this screw is a 5-pointed torx with a post, requiring a special driver to remove it. It is a size-6 (TX6) bit, bit with the 5 points and the post, I cannot find a driver to remove it. Has anyone had success with this?
I just purchased a new battery for my MacBook summer 2008 computer. Is there anything special I need to do besides pop it in the computer and let it charge? How long for the first time?
I removed battery without turning off my mac book pro. Now it will not boot up or remove cd. I tried restarting with eject, spacebar, command e, option, trackpad, and f12 depressed, individually each time to no avail. I installed a 2 gb. ram kit and loaded OSX Snow Leopard after removing battery.
y Macbook Pro booklet 'Everything Mac' WARNS: 'The battery in your Macbook can be replaced only by and Apple Authorized Service Provider, or an Apple Retail Store' (page 31). I was even warned, 'mess with the battery and you lose guarantee rights'.
OK - I wont touch the battery, but, hey Mr Apple, how do I clean my screen?
So I look it up on my Apple sanctioned 'Macbook pro users guide' in pdf: 'To clean your MacBook Pro screen, do the following: Shut down your MacBook Pro, unplug the power adapter, and REMOVE the battery.' (page 109)
Appart from the contradicting information, we have to remove the battery to clean our screen?!?
my macbook pro mid 2010 is indicating that my battery needs to be serviced. Before I call Apple or take it to the Apple store I wanted to reset my smc. I've looked already on how to do it, but I'm not sure whether or not I have to unscrew my macbook pro and remove the battery or if I can perform the SMC reset without it.
I have Mac pro about two months old. I am having problem with my Mac pro When I remove the betray charger, system running very slow and when I cannot charger it will run normal. I believe there is some problem please help me to fixed this I would like to give more details about my macbook pro.

On the bottom of my black MacBook, there is a circle that you use to loosen the battery. Today it fell off, so now the silver underneath part is exposed. I keep trying to put the cover back on but it keeps falling out. How do i get it to stay?
I used my Macbook Pro's Time Machine to restore everything on the iMac that I received. However, the battery icon is showing up on the menu bar (in between the bluetooth and airport). Is there a way to remove it? Are there any other problems from restoring files onto an iMac with a Macbook Pro's Time Machine?
I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!
For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!
If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
I have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?
purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?
i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.
been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?
I have a MacbookPro mid 2009 and have some problems with my battery. This morning I noticed that the battery was empty through it was supposed to be in sleep mode during the night. My battery has 97 cycles and has 99% of its original capacity. What could be the cause of this problem ?
I just want to make sure nothing else is wrong with my Macbook..have never replaced the battery in 3+ years...Always says not charging and once the magsafe is removed Pro shuts off...is completely dead battery the only problem..?
Battery Information:

So, I randomly clicked on my battery and noticed this "Service Battery" message. I had never seen it before. Obviously, this isn't a good thing. My Mac is 3 and a half years old so I'm not surprised this message poped up. So, I opened Coconut Battery and noticed my current battery capacity is at 65%. Even though charger says it's green, my battery isn't even charging. Should I make an appointment with Apple? My AppleCare expired so i'll have to buy a new battery when the time comes. I'm sure they're not cheap, either.
Apple Macbook Air late 2010, has been giving me poor battery performance even after replacing the battery under warranty. I am unable to find a solution, even the local apple service provider seems confused. Should I go for a replacement?My Macbook Air runs on the OSX 10.7.3 with all updates as on date. I use only softwares such as Microsoft Office for mac, Safari, Mail, iChat, iTunes regularly.
