MacBook Air :: Battery Only Charges To 99%?
Jan 7, 2011
I've had my 11" ultimate for about 3 weeks. Its mostly used by the wife around the house so I never really noticed before that the battery never charges to 100%. I'll leave it plugged in overnight. Open it up and it tells me it charged, however as soon as I unplug the cord it reads 99%. Does anyone ever see 100%? I know it really has no bearing on battery life, which is great on this machine, but all my previous laptops have said 100% when fully charged?

Bought in first week of release. I don't always leave it plugged in. I have followed all directions for calibration from the start. Is this within spec? The 97% figure comes from Mac's own battery monitor, and I haven't run any other battery-related software.

I bought a replacement battery for my 15" PB Titanium, and after the initial charge (when it reached 94%), it now only reached 46%. I have discarded the preference files that look like they pertain to the battery, but it still only charges to 46%. Anything else I need to do/reset/eliminate/change?

I have a 12' iBook G4 (1.33 ghz) that took a tumble and the power connector snapped off inside of it. I took it apart, popped out the broken bit from the dc-in board, and used it until the battery drained. It worked fine until then.I bought a new power cord, but it failed to charge the battery, and after searching through countless forums, I figured the problem was the dc-in board. I bought a replacement, and just installed it. Now, the battery indicator lights (the four green ones) are showing that it's charging up. It's on three right now. But the computer still won't power on. No fan noise, no other lights. I tried the PMU reset, but nothing. It's weird.

So I just go a new umb 13 and since opening last week the battery only charges to 99% after the first charge (went to 100% only the first time). I ran it down once to see how long the battery would last and when i recharged it, it says its fully charged but only at 99%. I then tried calibrating it but it once again stop at 99%. It has 3 load cycles so far. Is this normal? if this has been asked before im a newbie to a mac and i tried searching for it but couldnt find anything.

I upgraded from my old 13" Uni macbook to the 13" pro and I have not been impressed with the battery power. I get about 4 hours with half brightness, wifi on and light web browsing. Yes, i have checked activity monitor, CPU hangs at like 5% the whole time...Does this sound right? Furthermore, the battery will charge from 5%-10% to fully charged in little more than hour, like 1:15..that seems like an awfully short time to fully charge such a big battery...
Coco Battery reports only 1-2% wear with just a few cycles. I have conditioned the battery to no effect.

If I have a half-full battery and adapter plugged in, the indicator light is green and a "not charging" is shown on the top bar in screen. And the power in the battery will decrease in a speed between 0 and battery-only.
If I use a empty battery and adapter plugged in wall, the computer can start and run a few seconds/minutes and it will shut down randomly. If I closed the screen, the indicator light will finally go amber and begin to charge. I change battery and megasafe and it is the same.
I feel the reason is my mother board is not able to aquire enough Watts from the megasafe to support its normal running. So it consumes power both from megasafe and battery.

I have had my 13 in macbook pro for about three months and suddenly it does not charge when it is plugged in. In the last week this has started to happen but upon fussing with the connection like unplugging and replugging in the magnet charger it would start for a while and stop randomly. Now I can not get the computer to charge at all no matter how much I fuss. Do I need a new adapter or is there some other problem?

I know it's a strange questions but my mother's powerbook G4 1.5ghz just suffered from the infamous lower ram slot failure and does not fall within the warranty extension program. However, she has VISA performance guarantee and if the repair is going to cost too much, they will most likely offer to replace the computer with a new equivalent one.
This particular issue, apparently, is not really fixable and people who have their logic boards replaced often experience the same problem again later down the road. Since VISA has a no lemon policy and will replace automatically after three repairs, I figure it's better to save my mother the considerable hassle of having to send it in on multiple occasions...
So: I'm I want to find the most expensive authorized apple repair shop. Any 'good' suggestions?

I erroneously purchased the same 3 songs by the same band from 2 different albums twice.Is there any way to reverse the charges or get a refund on the double purchase? iTunes didn't ask for verification on purchase after the 1st song.. So I wasn't sure I purchased the songs.

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?

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.
