Laptops :: Macbook Pro Random Shutdown With Power Adapter?
Mar 16, 2010
Has anyone had the following problem? My Macbook Pro is 2.5 years old and has recently been shutting down for no apparent reason while plugged and unplugged into the power adapter. I went to the Apple store a few weeks ago for an issue where the Macbook Pro would not turn back on at all. They had to replace the logic board. But after that, I now have the problem of the shutdowns. I went to the Apple store and got a new power adapter because mine was broken. I thought that would be the problem, but it isn't. I also recently reinstalled my operating system and the problem is still occurring. Does anyone have any advice? My laptop is a 2.2 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM. My battery is in 'poor' condition, but according to the Apple experts, the battery has nothing to do with this issue.

I have experienced in the last few days a sudden shut down on my MacBook Pro. I've searched the web and found something about RSS (Random Sudden Shutdown) but I still can't find a solution.

I've been having an issue with my Macbook Pro, it keeps turning off while on battery power while I am playing a game (Starcraft II) despite having sufficent charge remaining. It won't turn back on until I plug it back in. Usually when I turn it back on the time and date are reset and the password to my wifi has to be rentered. The most recent time this happened after I plugged it back in the battery still had 79% charge remaining. I've tried recalibrating the battery and resetting the SMC both which did not solve the problem. The system report states that the battery's condition is normal and I ran a hardware test which also came back normal.

Randomly my Macbook will shut down and restart... has no pattern or initiation... Here is the Panic Report:

I wonder if somebody has a similar problem. MacBook pro 2008 (15", 2.2 GHz, 2 GB RAM) has the Magsafe adapter light off when fully charged. When disconnected-reconnected, it starts glowing green again.
History: about 6 months ago, the screen wiring and video card were replaced by Apple. The battery was replaced a long time ago. Symptoms after card replacement (not necessarily related to it) included spontaneous wake from sleep when the lid was closed, although the "wake from sleep at Ethernet activity" was disabled. In the Apple store they reset the power management unit and the unwanted wake up stopped. The computer is always plugged into the wall outlet when at home but travels often during the day and is on battery power then.
Two other laptops (2007 and 2009) always have the adapter green light on when the battery is fully charged. The "abnormal" one now has a replacement adapter plugged in and for several days the light was on when charged. Today it turned off again. Apple does not list that option and only vaguely states that when fully charged, the adapter light is green. Anything to do with the power port contacts? If yes, how can one diagnose or repair it? Will Apple hardware test do it? Or is this within normal behavior? Also, I am not sure whether this is serious or not since the battery charges...
I did not find any answers on the web, so I am posting it here.

I recently discovered my computer had died while it was sleeping. I tried charging it but am recieving the "Battery not charging, power source: power adapter" status.My power cord light is green, always. and the computer dies instantly when I remove the magsafe.
I've tried the "remove the battery, press the power button, plug in the magsafe" troubleshooting process, but it doesn't work.I've noticed that even with the battery out, the charger reads a green light.I've tried several outlets with the same results.Here are my battery stats

Serial Number: DP-ASMB016-384e-7636

Today I started to watch a video from a news site (probably using flash) and the computer started to slow down very much so I thought firefox had crashed. Then I force quit it and waited about a minute or two hoping the computer would get fast again as usual but it did'nt happen, so I tried to log out and nothing happened and then I tried to shut it down by clicking the power button and clicking in shut down.
Right after that, the computer started to shut down or log off (it was still very slow) and something happened it stopped in the middle of the process and displayed a blue screen (the same colour that appears when you connect another monitor to the mac). Then I thought of using my last resource: holding down the power button until the computer turned off but again, nothing happened.

Don't want to ask the Apple Store since they'll just tell me I can't, but can I use the 85W power adapter that came with the 15"MBP on the new Air with no damage? Ok, to use in a pinch?
Hmmm, how about the other way around (using a 45W power adapter on the 15"), I am thinking "no damage" just that it would take longer to re-charge?

I had an extra 45w power adapter in my office; which I used to use with my Macbook Air. So today, I mated it to my new i7 MBP15 and was expecting it not to work because of insufficient power. But it seems to work just fine.
Is there any harm in using the 45w power adapter at work and the 85w adapter on the roadhome? I'm assuming the 45w adapter just wont charge the battery as fast.

this might have been discussed before, but I just cannot find a threat about it: May I use my old 85W Brick of my older 15″ for the new unibody 13" Macbook Pro? The MacSafe Adapter certainly fits. But is ist safe to use it ?

I have a Macbook that is nearly three years old, and I'm on my second power cord. The first time I had trouble, the casing had melted off right next to the MagSafe part that plugs into the computer. I got another, and now it seems it won't charge at all. There is no apparent physical damage. At first, I could do a little jiggery pokery and if I got it in just the right place, it would charge. It seems that now even that is gone. I'm wondering if: 1. There is some obvious fix that I am missing, or 2. Where I can get an affordable replacement. I realised this makes it sound as if my current cord is brand new, that is not the case. It is about a year old.

I just bought MacBook Air, because my MacBook Pro died... I need two magsafe power adapters (for work and home) and I was wondering whether I could use my old ones from my MacBook Pro? The watt is way off, though (85 W versus 45W).

Just a quick question about my 13" MacBook Pro's 60W power adapter.The prongs have burnt, and I've noticed that sparks occasionally shoot out of the prongs when I plug the adapter into a wall outlet.Is this a known problem, and should I ask for a replacement adapter?

I've had the computer for over a year. It is currently insured with the Applecare. It seems like the adapter's cord is starting to show some normal wear-and-tear. It still works (i.e., still charging my computer), but I'm afraid that it will either rip or cause a short sometime. I've never dinged the charger. It just seems like the coiling made it come apart. See the picture below. Will Apple replace this under the warranty, or will I have to rake out $80 for a new one if this one gives way? image: [URL] I just got off the phone with an Apple rep, and he will be shipping me a new adapter. I'll just have to send him back the damaged one.

I i have a chipped power adapter and i'm not sure if it would be covered by my warranty. I'm not sure how it was chipped or for how long its been chipped but it could have been up to a week or more. The only way i can see that it was chipped is if my sister let the bunny out and it bit the wire.

I would like to know whether it is safe to, let's say, unplug the power adapter and then replugging it in like 20 seconds, for example, if I'm moving to a new room. Will it have a negative effect on the battery? I tried to search MRoogle but there are so many threads that it is literally impossible to find what you're looking for, sometimes.

I was very surprised and scared at the same time when I see my magsafe power cable frayed badly at one of the connections to the magsafe unit. I was very lucky to notice before sleeping, or else I would have ended up in a fire at my home. I was planning keep MBP for charging and go to sleep when I noticed this. But luckily I smelled burning and noticed that the frayed had part started blackening due to burning. I immediately disconnected it. See the pic below.
I use the charger as it is expected. Remove it from the solid plug and not cable. Actually I use all apple products with care and respect and I love them. But this incident broke my heart. I have so many presentations to give this week, how I am going to survive without my laptop is a big question. I just saw many people have had such problems, and I am hoping Apple customer care helps me out tomorrow morning. Only 14 minutes left on charging before my MBP dies. Apple help.
Strange thing is my power charger was just replaced 6 months ago for a different problem(it just stopped charging without any reason or visible damage, no fall nothing). And now after 6 months the new charger gave up with a frayed cable. I work as a Teaching Assistant and have so many presentations every week, this is a unnecessary trouble for me.
