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?
is it okay to leave my charger plugged into the wall socket on all the time? Even when im not charging my MPB? I have this strange fear that the charger will die on me faster if i leave it plugged in all the time.
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?Â

I have Windows installed on my MacBook. A few days ago. My MacBook showed a black screen . I plugged it into my charger and it works fine, once I unplugged it shows that the computer is on but shows a black screen. Another issue is that only windows is working. I cannot even logon to OS
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.
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?
Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
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.Â
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.Â
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.
Info: MacBook Pro, Mac OS X (10.7.5), 2012 edition
it only runs with the charger and also when I plugged in it starts automatically. The battery icon indicates that it has an 83% of the battery remaining. I don't know how it could happen and I would like to know if there is anything I can do because take it to repair it will be time consuming and I need for my job. The software is OS X 10.9.3Â
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.
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.
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. Â 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. Â
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? Â
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 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.
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?
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.Â
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!Â
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.
Is it better to keep the charger in after a completely charged or pull out the charger. Basically I'm wondering if the power is pulled from the UPS after the battery is completely charged or is it still constantly charging the battery.
I have a Macbook.Recently the sound on my Macbook has become very quiet and lacking in bass. I have checked all sound settings. The issue persists in OSX and Windows. The issue occurs with both speakers. Laptop has not been dropped or abused.Sound
I just picked up a pair of the Bose companion 2 and was wondering if you can adjust the base of these speakers? I don't see anything under the Macs Sound options.
I am looking to invest in my first pair of really good headphones. Now I am not a hardcore audiophile but I still like my music to be as clear and correct as possible. With that said I listen to hip hop almost exclusively and love loud booming bass. I know ill get crap for saying this but I actually like the sound of Beats by Dre and I can get the studio model but those things leak sound like crazy, but as far as I've heard their bass is the strongest.
Trying to add jump audio upgrade to my imac sound. The bass jump has great reviews but mostly for macbooks. They did not have one set up in Apple store so im on here to see what others might think of this product. My other choice as recommended by apple employee was the Bose companion 2. Only thing with this is they work from headphone in jack so i will have to keep them on all the time even when the imac speakers would have been fine for simple computing.
