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.

Last night I was watching some videos on my computer and noticed that the fans were spinning, because it was pretty hot. Next thing I know the laptop just shut off. I didn't think to much of it because I just assumed the battery dided and needed to be recharged.
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?

I've heard conflicting reports that leaving the laptop plugged lowers the battery life and that it is not true since it stops charging the battery. So is it bad to leave it plugged in all the time?

I let my new mbp(mid 2012) battery run down. It was on, I walked away for one minute and came back and the mbp was shut down. I plugged in charger and the mbp won't turn on at all. I got it on Tuesday so it is brand new.

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.

my laptop (macbook pro) doesn't turn on, because the battery doesn't work (may be because of moisture), and the 7 battery lights on the left side are off, and when I plug the charger in, the light on the magnetic socket turns on so dim ..

When not attached to the charger, my macbook pro (3 yrs old) will abruptly turn off. I can use it for 5-15 minutes and then the screen just goes black. At that time I can plug it in and turn it back on without a problem. I assume the battery is going bad.

My MacBook Pro power adapter lights up orange even though it is not plugged into a device. When I do plug it into my laptop it remains the same and does not charge. Due to this my laptop is now dead.
What does this orange light mean?

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

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.

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?

I've been told that I should replace its battery since it's been damaged. I haven't had the time or the money yet to buy a new one, and right now, I really need to use it.

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.

I just bought the new MBP 13" 'cause I'm gonna need it for college, but since I'll also use it as "personal computer", for web browsing, playing music and movies, I'll probably have to charge every day. My question is: if I got home and my MBP is dead, I plug it in and use it, when the battery is fully charged, I have to unplug it or I can use it for the night (still plugged in) and just unplug it the next day for school?
Is it somehow harmful to my battery life? And by the way, I've read that "discharge the battery" means just use at least until the 50%, is that right? So if I charge it just when it's about 40%, I just need to recalibrate once a month, and that's all fine, right?

My wife and I always leave our MBP plugged up when we are near a charger. This morning the MBP had been plugged up all night, but the battery was dead. I noticed the light was out on the charger so I went to take it out, but when I touched it it turned red indicating that it was now charging. It turns out it is very finicky and randomly stops charging. Anybody else had problems with their charger? It will be Thursday before I have a chance to get to the Apple store.

I bought my MacBook Pro 13.3" 5 months ago (according to Coconut Battery) and the battery-loadcycle is already at 51 and 89% battery capacity. Anyway I wanted to know, if I keep my Mac plugged in on the charger will the battery-loadcycles decrease?

I bought my macbook exactly two weeks ago (tomorrow) and I'm already starting to have problems. My battery is currently at 10% when not plugged in but then when I plug it in it won't charge. What is wrong with it?

Haven't found anything relevant on this. Basically my 2010 15" MBP just emptied its battery and is almost fully charged now. All this while it was plugged into electricity. Why?

i very rarely use my MacBookPro away from home (scared of loosing it, LOL) almost all the time it is plugged into the mains 24/7, i just shut the lid when i am not using it. It is about 12 months old, but i notice that the battery meter never goes above 96%, does this mean the battery is on the way out and is going to get progressively worse ?I suppose it means the battery isnt going to last anywhere near 6 or 7 hours if i did unplug it from the mains?

my macbook will not start unless its plugged in to a power source. if you unplug it while running, instead of switching to battery power, it shuts off. the battery is currently at 53%, so i do not know why it will not run on the battery.

I just noticed that my when I got my macbook plugged in, it's not charging. The icon is the one you got when it's plugged in (with the little fork-shaped thing in the middle), but instead of it saying 'charging' like when the battery isn't full, or 'charged', when it is, it just says 'Not Charging'. It's like it can see the magsafe connector inside, but the juice isn't coming through to the battery, even though the computer itself is powered by the charger since when I click on the power symbol I get 'Power source: Power adapter'.
Also, the magsafe connector itself isn't lit. It used to be green for a bit, but a much weaker green than normal, and before that it wasn't even lit--I've tried with three different wall outlets, one of which was outside my house where I usually use it (it was in a starbucks). Also, when I disconnected the magsafe to get a reading for the battery, it was only 1:35, even though the magsafe light was green (albeit a weak green). If it matters, I'm running 10.5.3. The macbook is still fairly new, bought mid-december, all updates current as I got it set to checking daily and install the minute I get the notice.

I have a brand new MacBook ( < 1 month old ). I usually leave it plugged in and sleeping on my desk, and open it up to use it. After about a day of this, it will still say the battery is fully charged, and the light on the MagSafe is green, but the batter display shows 99% (or 98%, 97%, 96%). If I unplug it and use it for a bit, and the plug it in again, the battery will charge back up to 100% (and then the whole process will begin again). I love my MacBook, and want to make sure this behavior is normal.

My aluminum unibody MacBook is plugged in to the power adapter and the light on the adapter is green. The battery status indicator says "Not Charging." What do I do?

I looked around and I find varying opinions. My laptop is mostly at home. Should I keep it plugged in when its full or should I let it drain? Please explain too.
Also, coconutBattery says I've used five cycles even though none of those were complete cycles. Is it just problems with the software or does it really count as a complete cycle?

So today I was using my MBP that I got about a week ago and all of a sudden I got a low battery message. My MBP was plugged in at the time, and had been plugged in for about the last two days. AC adapter was plugged in and very hot i might add. MagSafe never got disconnected. After I clicked ok on the low battery message my MBP just started charging like I'd been using it on battery power and just plugged it in. I know there was no power outage or anything like that, all my computer stuff is plugged in to a UPS that beeps if it looses power and switches to the UPS battery power. I shut my MBP down when I went to work and when I came back it took a good min before it made the powering on noise and the apple appeared. I checked my battery health and capacity through the system profiler and the condition is normal and it has 7 cycles on it.

This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.
Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.
What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep) to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.
I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.
Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.

I play a game called League of Legends which is fairly computer intensive. While playing, my battery continues to discharge continuously even though I have it plugged into the wall. I can usually get 3-4 games in before I have to stop and let the battery recharge. I have already decreased the screen brightness to half, turned off the keyboard back-light, and made sure that bluetooth was off yet the issue persists. I have noticed that the light on the charger seems to change colors often. It will cycle from green to orange to off then back to green again etc.
I have an early 2012 15" Macbook Pro with the latest version of Mavericks OS.

Macbook Pro 13" 2.3 ghz i5
4GB Ram, 240GB SSD
OSX.9.5 Mavericks.
Problem: Once shut off, my Macbook pro won't turn on by pressing the power button. It is as if I must jump start the computer using the power cord. What is interesting is that if I push the power button (without the power cord plugged in) the macbook won't turn on, then, when I plug the power cord in, the computer magically turns on without my PRESSING the power button. It is as if the computer knows it has been told to turn on but is waiting for more electricity.
When the computer is on, The power button also doesn't react when I press it. As recall, on macs, pressing the power button quickly creates a pop up menu that asks if:
a. you want to shut down the computer
b. restart the computer
c. put the computer to sleep
This computer will shut off if I hold the power button down but does not give me the pop up options.
Battery appears to be in good health. Though it has been through 780 cycles. Coconut battery says that the battery is fine. This Macbook Pro's Sd slot stopped working as well.

just curious, does anyone else's MBP's battery slowly lose charge over time even though it's plugged in? I've got a 2010 MBP 13". Mine only is ever at 100% right after I have used the battery and just recharged it. then it will slowly lose that charge over time until I unplug it, use the battery enough for it to actually charge the battery when I plug it in. (Oh, and coconut battery has never said it ever had 100% full original battery capacity, best it ever said was 97%).
