MacBook :: It Won't Turn On Unless Charger Is Plugged In

Mar 11, 2012

I have an early 2008 Macbook and it's been running pretty good up until this afternoon.  Now I'm having what is apparently not all that uncommon a problem, where my laptop will only remain turned on for as long as my laptop is plugged in. The second I remove the charger it turns off, and it won't turn back on again until I plug the charger in again. I had bought a replacement battery not all that long ago so I'm not sure if that would be the issue. It could be related that last night I installed more RAM into my laptop. I say could be because I was using the laptop NOT plugged in for the rest of the night and most of the this morning without any problems. It wasn't until this afternoon when I started using my laptop again that the problem arose. Could this be a delayed reaction to the RAM installation or is it just a coincidence and there's a problem with my battery? 

Here's the info from System Profiler:

Battery Information: Model Information: Manufacturer: SMP  Device name:ASMB016  Pack Lot Code: 0000  PCB Lot Code: 0000 Firmware Version: 0110 Hardware Revision: 0200  Cell Revision: 0102  Charge Information: Charge remaining (mAh): 4898 Fully charged: No  Charging: Yes  Full charge capacity (mAh): 4926 Health Information: Cycle count: 282  Condition: Normal  Battery Installed: Yes  Amperage (mA): 2123  Voltage (mV):  12198

MacBook Pro :: When Plugged In Portable Charger / It Shut Off / Can't Turn It Back On

Jul 1, 2014

I was launching my sims game when I plugged in my portable charger in my MacBook Pro. As soon as I plugged it in, I heard a tiny poof and next thing I know the screen turned black. I held down the power button like I normally would and it wouldn't work. when I plug in the charger, there is a faint green light.

MacBook Pro :: Laptop Won't Turn On Either Plugged Into Battery Or Not?

May 13, 2010

About a month ago I bought one of the new Macbook Pros, a 15 inch i7 version with highres matte screen.This morning I went to turn on my computer and I thought I had turned it off last night, but it turns out that I hadn't, so when I hit the start button it woke up and then promptly shut off. I haven't been able to get it to turn on since. Absolutely nothing happens when I push the start button, whether I have it plugged into battery power or not.

MacBook :: Charger Plugged But Says "Battery Is Not Charging"

Jun 14, 2012

About a month ago, the battery on my Macbook (the black one) started to get worse and worse, to the point where it would work if plugged into the charger, but would automatically turn off if disconnected. After much research, I bought a replaceable battery (not through Apple, but not through a sketchy website either) in hopes it would bring my laptop to some life. 

The new battery is now doing to same thing as before. Working if plugged in, automatically turning off if disconnected, and always shows that it is at 0% charge. Is there anything else I can do? I know I'm due for a new laptop, but I'd really like to keep this one around for just a few more months!

MacBook :: How To Know That My Battery Is Finished?

Mar 20, 2009

I have had my macbook for about 2.5 years. The past few weeks i have noticed some type of battery issue.

First I noticed that the led light on the charger was going back and forth between green and orange (charged and charging) (every 2-3 seconds).

I also noticed that on my top right part of my screen where battery life is shown it keeps going back in forth between (calculating....) and (Charged symbol: time).

Secondly, after about a week or so my battery started dying within 5-10 minutes after being unplugged.

Third, now my fan seems like it is always on high.

Is my battery just dead?

MacBook Pro :: Is My Battery Finished?

Oct 7, 2009

Unfortunately i was away from home for the last 3 months and i forgot to remove the battery from my macbook pro 2,2.

Now when i use the macbook pro it turns off suddendly when the battery is at 79% charge.... I tried to callibrate the battery and reset the SMC, but i see no change...

Is the battery dead? And even if it is shouldnt i get a warning or something before it goes dead?

Is there anything that i can do or should i start looking for a new battery? I must mentione that this happened also after upgrading to snow leopard.

I do not know if it has anything to do with it, but i remember when i upgraded to leopard i had my battery replaced under warranty cause the computer would turn off suddendly when the battery would each 30%...

Hardware :: Apple Battery Charger Or 3rd Party Battery Charger Bettter For The System

Aug 11, 2010

The Apple one looks tempting as it comes with 6 batteries and 29€ isn't too much, plus, as usual, it looks brilliant. I looked at some 3rd party chargers as well ranging from 20€ to 40€. None of them was stunning or special by any means. Cheaper ones usually came with two or four batteries and some came without batteries. I don't really need it for else than Magic Mouse, occasionally for something else too.

Laptops :: Macbook Pro With Finished Battery?

Jan 28, 2010

I've got a late '06 Macbook Pro, running OS 10.4.11, 2GB RAM, 2.16GHz processor. The battery recently died, but that's not a problem as I run it via the power adapter when at home.

Problem is, since the battery packed up, the computer itself is running slower than when the battery was installed. Is this usual?

It's a dualcore processor, and was previously fast enough to watch HD movies, but now HD movies are jerky, and the whole overall operating system seems noticeably more sluggish.

MacBook Pro :: Won't Find Battery Life Info / Plugged Or Not Plugged

Oct 17, 2009

I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.

I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.

MacBook Pro :: Charger Plugged In - Status Still (Not Charging)

Jun 26, 2010

I accidentally left it on while I was doing some chores. When I came back it was dead (no battery). So I plugged in the charger and it immediately turned bright green when its supposed to be orange first, right? MacBook says (Not Charging) but power source: power adapter, green light is on, on the Magsafe. It's running by the power source because the battery is at 0%. I've had the charger plugged in for less than/about an hour and the 0% still hasn't changed. (Not Charging) is still there too. I bought my Macbook last August 2009, so it's not even a year old.

MacBook Pro :: Retina 2014 Gets Really Hot / Even When Charger Is Not Plugged In

Sep 2, 2014

I purchased a MacBook a couple of days ago and it has been fine. However, today I've realised that the back of it at the bottom is getting really hot, even when the charger is not plugged in. I am not using powerful apps either.Sometimes it can almost be too hot to touch for more than a couple of seconds. This happens on any surface, whether it's on my wooden desk or not.

The back getting hot also heats up the rest of the Mac to some extent. does it need seeing to and if so will I be charged?

MacBook Pro :: Will Not Charge Even When Charger Is Plugged In And Working

Dec 4, 2014

I have been using my MacBook pro for a lot of film editing and motion graphics. Recently, I noticed that my battery kept going down, even when charging. I thought nothing on it and kept using it. After around 4 hours, the battery went from 90% to 23% WHILE plugged in. This got me nervous. When I plug in the MagSafe charger, the light comes on and I get the "charging" symbol in my toolbar. The light turns orange and then, after a few minutes, the power starts to go down instead of up. 

The laptop does charge, but only when I am running no application, when the screen is shut or when the laptop is powered off. Bear in mind that right now, I am on Firefox, that is the only application open, yet the charge is still going down. I assumed it was because I was using Premiere CS6, After Effects CS6 and Cinema4D, but now even when they are not open, the batter will not charge when I am using the laptop. 

I am currently only running Firefox and Finder. Now the laptop is charging as usual. However the second I open up Premiere, After Effects etc, it goes down.

MacBook :: Constant Drone Of Bass When Charger Plugged In

Nov 20, 2010

Whenever my MacBook has the charger in, there's constant 'drone' of bass from the subwoofer that my laptop is connected to, but as soon as I take the charger out the noise stops. Is there any way to stop this from happening (ie moving the cables round?) or is it just something I'll have to live with?

MacBook Pro :: External Speaker Buzz When Charger Plugged In

Apr 19, 2009

I've noticed a faint buzzing sound through my external speakers when a charger is plugged in to the laptop. Removing the charge kills the noise and makes the sound crystal clear again. Doesn't bother me to much, but as my uni-macbook pro is plugged in most of the time I can see this near constant buzz getting on my nerves a bit in the future. Any ideas, looking back I experienced the same thing with my macbook.

MacBook Pro :: Why Is 15" Beeping Intermittently When The Charger Is Plugged In

Apr 28, 2012

I recently bought a late 2011 15" macbook pro. Lately it emits a single beep every 5 minutes while it's running charger power. It emits the beep whilst charging and when the battery is full and the charger is still in. I've done a hardware test which didn't detect any hardware problems. The battery appears to be in good health and so does the charger.

MacBook Pro :: Charger Buzzes When Plugged Into The Adapter Converter?

Jun 12, 2012

Im in England currently (From the USA) and am using a "DYNEX" converter adapter to switch the electric current down so I can plug in/charge my Macbook Pro and iPad.  It works, however the charger buzzes pretty loudly and gets hot. I brought two, one started smelling like melted plastic and stopped charging altogether. That particular charger has faulted at home before (back in the USA), so I'm not sure if it died because of the converter or because it's just faulty.  

I have plugged in the newer charger and it also buzzes, but I'm really worried to keep it plugged in because I don't want it to fault out too. Is it normal for it to buzz like that when plugged into a converter adapter?

Hardware :: Leave Charger Plugged In Cause Extra Power Consumption

Aug 5, 2010

So I just got hold of a few of these new battery chargers from Apple and I'm just wondering if these are meant to stay plugged in the wall, even after the green light goes off. Does the light going off mean that the batteries will no longer draw power from the power outlet and that it is safe to assume power will continue to be consumed? Or is it preferred that I plug and unplug the charger only when needed to avoid any, unnecessary, extra power consumption?

Well now I go to restart my Laptop and it will not turn on even with the laptop plugged in. Any ideas on what could be wrong? Is my laptop dead, what happened?

MacBook :: Computer Turn On When Plugged In But Not Charging

Mar 28, 2010

I have a black macbook. My computer wouldn't turn on, so I plugged it in and turned it on. I noticed that it said "Not Charging". I figured it would go away and start charging. I closed the computer and came back an hour later, and the light on the charger was still green and not amber. Why will my computer only turn on when plugged directly in, and why won't my battery charge? Do I need to get a new charger or a new battery.

MacBook Pro :: Charger Turn On And Off (Green Then Orange Light)

Jun 3, 2012

My Macbook Pro's charger when I plug it in turns on (green light then orange light) and after a few seconds it turns off and back on again. I tried unplugging it and plugging it back in after several seconds and I also tried different power outlets but it still doesn't work properly, I even tried restarting the SMC (Not sure if I did it right though). What could be the cause and I have a Macbook Pro 13" Late 2011 model running Intel Dual Core i5 Processor.
