MacBook Pro :: Power Connection Isn't Working?
Jun 26, 2012
I have a new power cord for my MacBook Pro. I plug it into the laptop, it turns green for about one second, then goes to orange. It doesn't show in the battery icon that the battery is charging, but if I turn the laptop over and look at the battery, the green indicators on the battery are blinjking like it is charging. I keep getting the "now running on reserve power" error. Now, just two minutes later, all of a sudden the screen gets brighter and the battery life indicator on the screen shows that the battery is at 74%! How could I be running on reserve power at 4% one minute and be at 74% the next?

My Macbook has no power at all. None from the cord, none from the battery which was fully charged. I noticed only a couple of days ago the little green light on the connection flickered a couple of times. I took the extension off the lead and used the plug on the power box. I also took the battery out and put it back in.

I have Logitech MX5500 bluetooth keyboard and mouse connect to my Air via Steermouse.
Past week, the bluetooth is acting weird. When waking from sleep mode, sometimes they connect, most of the time, they won�t. I click on the bluetooth logo to manually connect, but the bluetooth option pop up 30 seconds later, not instantly.
I had to restart my Air to re-establish the connection. Anyone else encounter similar issue?

The ethernet connection has stopped working on my MacBook. It has worked previously but now says no cable is installed. I have looked at the port and no damage is noted. I tried a known good cable from another system to no avail

I use a 4G Galaxy Nexus to broadcast a private WPA2 network. The 4G signal is always strong, and I've verified that the internet is active on the broadcasting device, and that other non-Apple devices maintain a solid connection. However my macbook pro does not lose the network connection, the internet stops working only on the macbook pro and I must "turn Wifi Off" and back on using the top right menu icon in order for the internet connection to resume working on the laptop. It will stop working every 5-10 minutes.

If so, how do I avoid frying my macbook air and other electrics, like my iPhone, camera battery, and shaver. ?had that built in or something, so as to just buy a weird 3-prong adapter...I saw the set of adapters available on Apple's site, but those would then only work for my laptop charger. I'm sure I could find the UK 3-prong to US-adapter... but what about voltage? I've never traveled overseas and had to convert power before

I've been experiencing the following problem with my late 2007 MacBook Pro: I can't use it on batteries. As soon as I disconnect power supply, it works for 10-15 minutes and switches off. Not sleeps, but suddenly turns off completely. The system battery indicator drops by about 10% (showing 85-90% battery charged), whereas 4 out of 5 LEDs are lit on the battery itself. After such a sunned switch-off, I'm not able to start again the laptop - it doesn't react on Power On button - like the battery wasn't inserted at all. Right after I plug on power supply back again, everything gets back to normal and I can use it normally, but still only if it's connected to the electricity.

Ok. so my MBP was working 2 days ago and I went to Fry's to replace the HD with a 640GB model thinking larger storage - win. Replaced in and the orange ribbon cable got disconnected between the keyboard and the logic board. Went frantic and after a visit to the Apple Genius, they plugged it back and thought i was fine. Nope, and now the unit won't turn on. Plugged it in and got the green light and battery charges, but the MBP won't power on. I made sure the HD was plugged in securely, the orange ribbon connected fine, and the power button cable was secure. The drive worked fine as I did a superduper transfer of the old data to the new drive the night before the crisis and it worked fine.

After 1.5 years of use, my hard drive suddenly failed. This was later confirmed by Apple Genius Bar. So I purchase a new SSD from OWC which was instructed to be compatible with my laptop model (MBP 13" early 2011). It arrived today and I did the installation carefully and successfully. However, after putting the back panel back in place I was unable to power up my laptop.
It was as if the power button is not working. Then I opened up the back panel one more time to realise that every time I click the power button (turn on), the fan started running, this can only be stopped by pressing the power button and held it (turn off). I tried placing my old hard drive and it doesn't work as well. I tried reset the SMC by holding power-shift-option but same result.

I have searched high and low to find a simple adaptor connection cable to link my Hi Fi to the G4 so that I can record my favorite old LP's and cassettes into iTunes and burn them onto CD with Toast 7 once cleaned up. A wireless unit that works in reverse to the iPod to Hi Fi would be ideal. If I had the technical expertise to design one, assuming not already available somewhere, I would patent this rather than having to have cable traveling from room to room.
The longer the cable the greater the audio loss, if you believe the cable manufacturers. Some of the music I want to record is just not available on CD whether original LPs or in compilations. One artist in particular, Annabel Lamb, I have requested the iTunes Store to incorporate several times with no response. Even the technical Q and A on Roxio's site does not help. Roxannes great the way she tracks the pointer though.

I just got a new Intel Mac Pro (10.7.4) and cannot access my network. My older G5's (10.5.8) used afp to log in but now I get this message.There was a problem connecting to the server. The version of the server you are trying to connect to is not supported.Is there something I'm missing? My networked is wired and runs to Windows based server. All my other Mac G5's can still access the server the way I always have before.

Starting this morning an X has appeared over my battery icon. When I click the icon is says no battery available. When I check the system profiler it says no battery installed. When I click the button on the battery all 6 lights turn on. I have read similar posts to this that say when they unplug the power supply the mac turns off in a few minutes, mine however will stay on the same amount of time as if the battery was charged. I'm surprised that this happened because I bought a new battery 3 months ago because the original one short circuited when my hard drive went last summer.
I had to have the power supply constantly plugged in if I was using the computer. I tried shutting down the computer, removing the battery and restarting and that worked. However when I shut down, unplugged the power supply and tried to restart, it did not turn on. I'm hoping there is a solution as I use my laptop on the road often and not being able to turn it on without the power supply is a real inconvenience.

I spilt some water over my unibody MacBook Pro about 36 hours ago. It was dark, and as the screen didn't respond I assumed that it had shut down, but on closer examination the next morning (after turning it upside down) I found that it was still running. I shut it off then. There didn't seem to be much water inside the MBP, so I tried turning it on just now. It made all the right start-up noises, but nothing on the screen (the Apple logo also wasn't illuminated). I forced it to shut down again right after.
I'm not near a service centre at the moment, so am wondering if I should just wait a few more days, or get it sent in right away? I guess the fact that it starts-up is encouraging, so hopefully the damage is just limited to something connected to the monitor. No water was split over the LCD itself, but I'm guessing some may have entered at the back of the unit, where it connects to the main body. I did almost the exact same thing to my 3yo MB about 2 months ago, and it started working after about 3 days. I guess I should be more careful about what I put near my computer in future!

I was charging my macbook. It was charging when I left, upon my return, after about 30 minutes, I found that the light was no longer green. There was no light on at all. I tried restarting multiple times. There are no stuck prongs in my power cord. I tried different outlets. I tested the outlet to verify it worked. My computer will charge fine with other power cords, but just not the one I want it to use? Is there anything else I can try before purchasing a new cord?

I have a 2011 MacBook Pro 15 inch, and the Messages application has been installed and functioning well for the past year. A few hours ago, my MacBook ran out of battery and died on me. This caused a number of applications to function incorrectly, however, after a restart all of the applications EXCEPT Messages work correctly. Now whenever I start up the messages app and try to send a message to one of my contacts, their name appears in red and I receive a message that says "###-###-#### is not registered with iMessage." This occurs even though the contacts DO have iMessage and were working in the past. None of the contacts work currently.Â
I tried signing out of Messages, restarting my computer, restarting iMessage from my phone, deleting my plist file, but none of these seem to alleviate the issue.

My airport doesn't seem to be working. It's completely connected--I even ran through the diagnostics and it said nothing can be done for it--but it won't pull up a Safari page, let me log into AIM, or check my Mail. It works fine when I plug an ethernet into it, and I've tried restarting my computer multiple times, and I reset the DHCP, too, and nothing.

So I have a mac pro, sick machine, love it, and want to play some older games, such as half life 2 as the mac port glitces and sucks for me.
So here's my endeavors with Boot camp. Ran the partition and inserted my windows disk.... a note on that. I did not have a xp with SP2 or better so I made one using a program and "slipstreamed" SP3 into it.
I then installed xp. Had a problem thou. When it wanted to start windows for the first time it rebooted and then never went anywhere but a blank screen. I rebooted it manually and it dumped me into windows just fine. No sound, and many other drivers missing. It did not ask me for my Leopard disk like many said it would. So I inserted it and it installed all the missing drivers for me.
However, the network connection did not work. everything else save my numpad seems to work. I have no idea where to start. I have done everything I do on my PC Laptop set up to run fine within windows and the router. I even installed Bootcamp 2.1 as a post said it might be a problem there. IT did say it must be installed prior to SP3 but thats not really possible with my system due to it (SP3) installed with windows prior to reading about the 2.1. I need to connect so I can download files I need to run the games I wish to with this thing, otherwise I wouln't bother.

I have been using my Macbook wirelessly for over a year now and never had a proble before until this morning when I was surfing the internet and for some reason it asked me for my WEP key which was not a problem because after entering it my wireless connection started working again, but after a while it stopped working again but this time it didnt ask me for the WEP key in fact the wireless icon has the check mark as it would be working but its gray out.
I know it is not the router because my other laptop is working fine.
Any idea what could be wrong?
the internet works fine if I connect it to a wired connection.

I have been using both messenger 7.0.2 and the beta version of 8 for some time. I have recently upgraded both to Snow Leopard, and changed my ISP to TPG (Australian ISP). Ever since, when I attempt to connect to messenger (either version) it says the connection failed as I am not connected to the internet. My internet works fine so I am at a loss as to what the problem is.
