MacBook Pro :: MBP Battery Loosing Charge When Turned Off?
Oct 28, 2010
I've been a member here for a few years but mainly kept in the background reading about news and other interesting things like mods and discussions.
A few months back I bought a 15 inch 2.4 MBP, the most recent model as far as I'm aware, from the refurb store in the UK and after a few troublesome experiences ( they delivered an iPad to me the first time) I finally got my computer. Ever since, there have been a few problems.
First my Logic board died, handed it in and got it fixed.
Second the Keyboard backlighting wouldn't work, same thing, handed it in and got it fixed.
Now it seems that my MBP can't hold the battery charge when the computer is turned off, which to me seems very strange as it holds the charge perfectly well, 5+ hours although I've never timed it, during normal use.
I recently installed and mce optibay for extra storage since I don't really need the superdrive and it works great. Could this by any chance have anything to do with the drain?
So to summarize my MBp can't hold the charge when computer is turned off but works fine when its on. I have an extra HDD installed where the superdrive used to be via mce optibay and everything else works fine.
After all is said and done, and heavy Macbook Air use, there is only one thing still bugging me. Its not the slightly uneven lighting, not the 3 hours charge nor the 3:30 battery life I get constantly, nor the 6200 RPM fan. When I charge to 100% and let it sleep for 12 hours, I lose about 20% of the charge. Yesterday I was at around 25% and when I opened it this evening, 24hrs later, there was nothing left. If I leave the macbook air closed, I think that the battery would reach 0% after 3 days. This is not normal and some kind of leak.
So I usually keep my UMBP plugged in at all times. It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. Brightness on screen is set all the way up, if that has anything to do with it.
I have a Week 01 MacBook Air, and I just started to notice that my MBA has not been performing its best since I bought it.
This morning I at 0745am, but now its 0831 and my battery is now at 53%; is there something wrong? I took a stopwatch and averaged it at about 53-55 seconds where the battery will drop 1%.
According to coconut battery, current battery capacity is 4670 and original battery capacity is 5090, and the system profiler says that I'm at 31 charge cycles. And YES, i've reset the PRAM, PMU/SMC, and calibrated my battery
I turned off my macbook pro when it was at 100% before my flight. When I landed I tried turning it back on and it wouldn't turn on or charge. That was two months ago and I just tried charging it again and if I play with the charger, it lights up then totally fades away. I'm not a computer wiz so I can't take it apart to fix it or anything like that and I really don't feel like going and dumping a lot of money on a new computer.
Just bought a new 15 inch retina MBP. My question is...should I immediately charge the battery or let it run to zero first and then charge it? Does it even matter?
Info: MacBook Pro with Retina display, iOS 7.1.2, Retina, 15 Inch
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?
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.
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?
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 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..?

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.
My iBook G4 is 3 years old. I have 2 problems: My latest problem is that it won't charge the battery. I bought a new Ac Adaptor, and I used my battery and my adaptor in another G4 and it charges, but not in my computer. So I know the problem is INSIDE my computer. My father replaced the.DC-inboard when the pin off of my old charger broke off inside the computer.
2.) Now the computer won't turn on. If it does turn on it shuts off 20 seconds later.
There is no warranty, I don't know where to start with fixing it since I can't get it to stay on.!
I have had my macbook for just 6 months....at the beginning it was perfect with a very good battery life.Now at 99% charge (as it refuses to finish charge to 100%) It now says 10:00 where the battery time is and last less than 30mins.
Also its charge capacity is JUST 708 !!!!It was over 4000 just 6 months ago.Im sure my battery is on its last legs, anybody know if I am entitled to a free one?
Charge Information: Charge remaining (mAh):708 Fully charged:No Charging:Yes Full charge capacity (mAh):708 Health Information: Cycle count:110 Condition:Check Battery
I have a Mac 10.6.8 running Snow Leopard. My battery won't charge: all I get is "Not Charging" in the menu bar battery status; the power adapter doesn't light up either. It's not a problem with the battery—when I put my battery in my friend's MacBook, it worked just fine. His battery, however, wouldn't charge either when it was in my computer. I have tried resetting the SMC several times, following the instructions exactly. I've reset the PRAM, run disk repair, and fixed disk permissions. I don't have the money to take it to a repairman—even if I did, I need my computer every day for work.
Ok, so I just did a battery calibration and once the battery got really low, it shut off, but didn't go to sleep like it has done before. It completely turned off; the battery light indicator is not indicating it is asleep. I've never seen it do this, has anyone else had this happen? I have a 2006 MacBook Pro, 2.33 C2D, non-unibody.
having problem charging battery . sign just shows a cross on it.the lead shows green and will not go to orange,hence it is just working off the mains.Bought new battery, worked for10 days now having same problem.
I currently using a Aluminum MacBook 13' but I don't know which way is the best to charge the battery. - Plug-in AC supply and charge the battery while using OR - Take out battery and use AC supply while using
Our old battery said it was needing to be replaced and my dad went out and bought a new battery for our 15" MBP from 2008 - running SL. I've put it in, it works, I've plugged the power cord into it, and the little light that indicates it's charging doesn't turn on. I checked in the menu and it said the battery isn't charging.
I've already pulled it out and then put it back in, shutting down of course. And I just tried resetting the SMC which has done nothing. It's not under warranty. I've just put the old battery back in and it doesn't seem to be charging it either. I'd be curious if the power cord was faulty, but it's powering the MBP at the moment.
ijust calibrated my batttery and my charger light is green which signifies its not charging anymore..and the icon at the top of my screen says charged..BUT Coconut battery says my current battery charge is as follows:
Current Battery Charge: 5807 mAh
Maximum Battery Charge: 5853 mAh
@99%
Current Battery Capacity: 5853 mAh
Original Battery Capacity: 5770 mAh
@100%
Additional Info: Battery-Loadcycles: 6 Age of Mac: 7weeks Charger Connected: yes Battery is charging: no
so my battery charge is stuck at 99% and its been plugged in for the past 3 hours, and its saying my current battery capacity is higher than my original battery capacity.. is that normal?.. i cant seem to get my battery to 100percent and its not charging..
here is a screenshot of coconutbattery after calibration, i just got my macbook last week..should i be worried about the battery at all?
1) When you first get your Macbook Pro, should you let the battery die out completely and then fully charge it? Or should I charge it fully first? Or what? I don't want to mess up the battery with the first charge.
2) Do you leave your Macbook plugged in while you sleep, are not using it, etc? Or is that bad for the battery?
3) I've heard somewhere that it's bad to shut your Macbook off when you go out/go to sleep. Would it be wiser to just set it to "sleep" and keep it plugged in or something?
Power cord will not light up and charge battery on my mabook. I have already taken the battery out and gone through the steps for resetting. Worked along time ago when this first happened and now its not. Do I need a new battery?
When the magsafe adapter is connected. Has anyone else got this problem. N.B. The charging icon in the top right hand corner only displays the words (Not Charging) I have been told by Apple Care to try a PRAM reset and a SMC reset, but the light on the mag safe never turns amber, just stay lit green.
I'm using a MacBook Pro 13' and it's one year old. I bought it last year March. But after I purchased it, few months later, my laptop started playing up. First, it's faulty hardware, and i sent my laptop in to get a new hardware. Not long later, the battery won't charge. Whenever I touch or drop the adapter or connecter when it's charging, my laptop will shut down itself, and resetting. (when i tried to switch on, the date has changed) And it won't charge anymore. I get frustrated when ever I ask for repair and it seems nothing happen in Apple Care, and they refuse to repair it.
My cat knocked over a glass of vodka/sprite onto my 13" white MacBook (the older version, from 2007 I believe). I let it dry out and took the battery out and everything and let it sit for a few days. It turned on when plugged in but the battery was dead. I purchased a new battery to replace it thinking it was just that the battery got ruined. However, the new battery I purchased will also not charge. It came partially charged and it worked and my MacBook had power without the power cord... until the battery died, and now i cannot get it to charge back up at all. Is this something that can be fixed? If so can I do it on my own or would I need to bring it to a Mac store, and what would that cost me? My concern about taking it in to get fixed is what it would cost me and if it is worth it seeing as my MacBook is pretty old.
got my 13" MBA and am very happy about it. I plan to baby this thing, and I am always very conscious of battery life for all of my devices, so do any of you have any advice for how to best handle the first charge/discharge cycle?The machine almost fully charged out of the box. Should I run it down to zero and then fully charge it? Should I fully charge it first and then run it down?
I just got a new macbook air, it was working fine for a couple of days until yesterday.
The battery seems to be stuck at 98% - or was. I rebooted because I started to lag, and was updating, then I unplugged it and plugged it back in, then it went down to 97%. What confuses me is the fact it had been plugged in (while shut off), for about 8 hours and it should have been charged by the time I got around to using it. When I right click on the battery icon, it says the computer is fully charged.
