My screen flickers on my new UniBody Macbook. The problem occurs intermittently and seems to only appear when the computer is on battery. Should I take the computer to be replaced at a genius bar or should I wait for a possible software update. I have the 9c8c screen, so I don't want to risk getting the fairly inferior screen.
View 10 RepliesMy battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
Just doing my normal multitasking on my 17" it runs fast while with the magsafe plugged in but on battery its pretty slow. But then I am transferring a 100gb+ file while using 6 spaces with many apps running.
View 3 Replies View RelatedI took this 13" macbook off of my sisters hands as she has already bought a new one for college. My hope was to save it, as it had stopped working a few months after she spilled some sort of drink on the keyboard. Here's the short story: Took it to local tech support office once it stopped working. They said logic board needed to be replaced, so it's a done deal. Opened it up, cleaned the entire inside of the computer with 95% alcohol and a toothbrush. Let it sit for a day to dry. Turned it on. It worked! But it was finicky in terms of when it would charge and when it wouldn't. Eventually stopped working again when the battery ran out of power and it would not recharge the battery or start up without the battery and just the power. Took it to a friend's house who has the same laptop. Swapped his charged battery into mine. Computer booted up and ran fine. Forgot to test if it was charging consistently by plugging my AC adapter into my computer.
However I did test my AC adapter on his mac with his battery, and that did work fine. So I had eliminated those as the problems and figured it must be something inside the computer. After researching, figured the problem must have been the DC-in board. And I ordered one of these: [URL] and installed it no problem. Now the computer will only charge when it is on and open. If I close the screen it will not charge. And once I open the screen, it shows that it is charging, but 0 battery life, then corrects to the proper amount, then 10 seconds later the light on the mag-power connector comes back on. Another important detail, the computer will not turn on or run while the battery is removed. Perhaps only the part of the logic board that controls the power directly from the mag-connector is fried, but the part the directs it to the battery is ok?
Also just noticed: When the power chord is unplugged, there is a consistent and accurate display of remaining battery life. However sometimes when I plug the power chord back in, it will read 0%, then random other percentages, while the light flashes between green and orange on the top of the power chord. I would like to be able to charge the thing while its closed. Also does this sound like a quark I could just live with? Or does it indicate it will probably fail very soon? Because I could live with this for another few months while I'm waiting to be able to afford another laptop. Even if it meant finding some alternative way to only run it off of only battery power, buying two batteries, and charging them outside of the computer through some third party laptop battery charger.
When I turn on my Macbook it does not go past the initial screen with an apple and spinning wheel. I took out the battery but am wondering if I need to do something special when turning it on again?

I just replaced my battery and now my computer shuts down randomly no matter how much battery power I have. Most recently it shut down with over 70% battery life. I followed the instructions on the new battery, but I can't figure out what is causing this type of issue based on my settings that didn't change from the original battery.

What effect will the macbook have, if i fully charge and discharge the battery on a daily basis. I will leave it running on battery power when i leave for the day, and let the battery drain/discharge fully through the night.I will hook it back up in the morning to have it fully charged, may be 30 - 60 mins after it being fully charged, i will pull the power out and run the laptop the whole day on battery.

I was wondering if anyone knows of other ways to control the computer to preserve battery life. I'm thinking mostly about underclocking the cpu. Does anyone know if this is possible and also if this would benefit the battery life? I'm on Aluminum Macbook OS X 10.5.8.

While unhooking my battery, I accidentally touched the metal contacts near the battery cable connector on my mid 2009 with a screw driver. My computer says 'battery not found' and only turns on while plugged in. The computer doesn't detect a battery in the system profiler. Will buying a new battery resolve my issue?

Apologies if this has been posted before, but rather than trawling through the thousands of threads, and before hitting the Genius Bar.... thought I would run this by the experienced MBP owners first.Got my first MBP (crossed over from PC back in April), and within the last couple of weeks, noticed that the screen is flickering intermittently.
Wondered if it's a glitch stemming from the switch from Graphics card as/when needed, or if it's an indication of something more serious and warrants taking it in to the Genius Bar... (don't want to part with it for days unnecessarily).
Here's my hardware, purchased in September of 2009. Model Name: MacBook Pro Model Identifier:MacBookPro5,3 Processor Name: Intel Core 2 Duo Processor Speed:2.8 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 6 MB Memory:4 GB Bus Speed:1.07 GHz Boot ROM Version:MBP53.00AC.B03 SMC Version (system): 1.48f2
I'm running OSX 10.6.8. and have only used approximately 200GB of my 500 GB Hard drive. My mbpro simply hangs. I'll open a browser, or hot corner my spaces, save a file, whatever, and my laptop will not respond. Sometimes my cursor will still be movable but won't actually activate anything. I frequently get the BBOD and all I can do is wait until it stops and then all the cursor commands and keyboard clicks I made while it was spinning, execute...or not.I have run the Apple Hardware Test which came up negative. I've downloaded and installed ClamXAV which only came up with a couple of domain spoof type viruses which I've quarantined and deleted. I've got Little Snitch telling me what connections are going out but it seems that there's nothing unusual, but I frankly don't know that much about the processes other than what I have looked up on goole.I have looked at the Activity Monitor and every not and then, right when my machine hangs, I'll see a spike in Network Activity pane but almost seems as if the spike isn't being read because the processes that come up seem to be legitimate and often, they don't show that they've taken up all the bandwidth. Please help. I've got a G4 quicksilver from 2002 that still kicks A and my MBPro has made me nervous ever since switching to the Intel chipset. (Don't know if that actually has anytghing to do with it.) Lastly, I think there's a chance that I'm the fool who opened or executed something downloaded from the internet. It could have been a dashboard widget or an extension or add on or software or whatever.

I have a late 2013 Macbook Pro with retina display. I have had an intermittent problem with the cursor disappearing. It is extremely annoying and I haven't been able to stop it.
I reset the SMC, it worked for a while but the problem is back now.
I have had my MacBook (aluminum) for 6 days, and all of a sudden i go to plug it in to charge (10% left) and the led on the magsafe doesn't come on and the computer doesn't recorgnize the charger (even in system profiler).
upon closer inspection i noticed the LED is on on the magsafe, it is just a very faint shade of green.I have tried a charger from a different MacBook but no luck. And i have also tried my charger and a different macbook and it charged it just fine.. so it's probably not my charger.
Any ideas?? i know i can go get it replaced.. but i would really like to not have to take a 45 minute drive to the apple store if i can avoid it.. (unless this problem is serious and should be replaced) also, if i get a replacement is it possible for them to just swap my HDD with the new one?
I have a MacBook Pro 2.33 GHz Intel Core 2 Duo, running Tiger 10.4.11. It has an issue where it takes a LOT of tries (10 - 20 tries) to get it to start up. When I hit the power button, it will turn on, the hard drive spins, the fans go, the usb ports work (I had a laptop cooler hooked up to it that would spin when I turned the computer power on), BUT the screen stays black, no chime. If I keep trying, by holding the power button down for 10 seconds and then hitting it again, it will usually start up on the 10th or 15th or so try.
I've tried varying amounts of time between tries, five minutes, ten minutes, overnight, etc. I haven't done any recent software or hardware updates. Once the computer starts up, it works just fine, aside from running quite hot (typically 60+ sometimes up to 80+C when I'm running photoshop or illustrator).
I have an older macbook 3,1 running Mavericks OS and recently one of my left USB ports has not been:
1) able to eject external hard drives plugged into it (I have to force eject)-instead it gives me a message that one or more programs may be using it (even though I don't have any programs using it). The hard drive is being powered by USB has a 3.0 connection although this wasn't a problem in the past... I tried the other USB port and it can eject just fine from that port.
2)Intermittent communication with mouse. Not sure if this is a hardware issue but when I try to run diagnostics on this laptop by holding down the "D" key at startup it doesn't take me to diagnostics. I no longer have the discs for this laptop (containing said hardware test) so I can't boot the diagnostics from that discs.
In lieu of a hardware test I opened CONSOLE and did a search for USB and there were a couple of these messages:
8/29/14 12:13:43.000 AM kernel[0]: **** [IOBluetoothHostControllerUSBTransport][SuspendDevice] -- Suspend -- suspendDeviceCallResult = 0x0000 (kIOReturnSuccess) -- 0xdc00 ****
Is this a logic board issue? Would rolling my OS back to pre-Mavericks work? The problem didn't emerge right when I updated to Mavericks however I have had luck changing OS stuff (updating or rolling back) with faulty USBs...
Here are other troubleshooting methods I have attempted with no success: -Disk Utlity (repair disk and permissions)
-RESET PRAM NVRAM
-Remove battery
-RESET SMC
-Shut Down
-Run Disk Utility @ startup
I'd like to get access to a Hardware Test compatible with my macbook. The links I have found online are to incomplete files.

I have a 17-inch MacBook Pro and a 27 inch Thunderbolt display. I've been using both for about 2 years now. On occasion, the display disconnects for no obvious reason. Unplugging it from my MacBook Pro and replugging it in seems to solve the problem, but its been happening more frequently lately.

So today I managed to drop my MacBook a short distance to the ground. I can't believe I did this. The computer was asleep at the time and, as far as I can tell, the internal HDD is perfectly fine. After I dropped the computer it wouldn't at first wake up from sleep. After removing the battery and replacing it, it booted back from the state saved to the HDD. My problem is that my optical drive makes noises now. I never use it, but whenever the machine tries to access it (waking from sleep, launching Disk Utility, etc) it makes noises as if the eject mechanism is running constantly or something else like that. The case also slightly bulges where the drive is. Now, if it doesn't work ever again I will only be slightly sad. I haven't tried to put a disc in it yet, but because of a previous spill by a previous answer the fibers around the opening are so stiff that getting a disc out of the drive when it works is a pain. Any ideas of what might be wrong and how to possibly fix it? I haven't tried resetting the drive, I don't have the time tonight.

[URL:...] apple on Thursday released an EFI firmware update for 15-inch and 17-inch MacBook Pro mid 2010 models that fixes a freezing or stalling problem. According to Apple, EFI Firmware Update 1.9, which requires Mac OS X 10.6.4, "resolves a rare issue that may cause the system to freeze during startup or intermittently stall during operation." The update, which is a 2.16MB download, also improves external display compatibility.

View 1 Replies View RelatedI have a macbook pro (identifier MacBookPro 5,1) which I have been happily using for about 18 months, however recently the screen has been acting up. It will occasionally display lines one pixel wide, but over the whole screen (it's quite difficult to describe so I've attached a photo). This happens seemingly out of the blue, probably once every few hours of normal use, and the only way I've been able to get it to go away is to close the laptop, then open it again - Sometimes it only takes a few goes for this fix to work, sometimes a a lot.
View 2 Replies View RelatedMy late 2008 macbook intermittently makes a gentle "ding" sound. By gentle I mean it's a sound effect, not the kind of beep you get from about to die hardware. I cannot work out at all what is causing it.
Sometimes it doesn't happen for weeks then will happen several times in a single day. It happens when I am not doing anything at all (ie. not even pressing keys).
I've checked all the sound effects that you can choose in system preferences and it's not the same sound as any of them. I don't use Mail or any other email clients but just in case I checked once when I heard the ding - and I didn't have any new mail. I've also checked my dashboard, and as far as I can see the calendar, clock, weather and calculator widgets don't seem to be set up to make some random alarm sound.
I acquired a Unibody MacBook that experienced a little water damage. The logic board was definitely shot, so I replaced that yesterday and initially the machine was working like a champ, save for a few issues:
1. The machine tries charging my battery, but eventually gives up and decides that there is no battery in the machine (there is a battery in there, and it shouldn't be dead yet, should it?)
2. I've been experiencing an issue in which the MacBook and charger aren't getting along. I've got two different chargers, both of which work on my pre-Unibody MBP consistently but sometimes I'll plug one into the MacBook and get no light, and in other cases I'll plug it in and get just a very faint green light. In either case, the machine won't start up. I usually tinker with the machine for a few minutes, taking the back plate off and checking connections, waiting a few minutes, and it's back up again.
3. Before the machine starts up, the LED blinks three times. I initially thought this was just a blink pattern to notify the user that the logic board doesn't have a serial number yet, but I've run the serializer and entered a SN in, and it still does that. Is this normal for these Macs?
I know that these MacBooks are a little more intricately tied to the battery than previous Macs. Does anyone think the above problems (at least 1 and 2) would be solved by a replacement battery? Or does it sound like something else is wrong (perhaps the DC in board)? I've never heard of anyone needing to replace a Magsafe DC in board (and from their low prices online, I'm led to believe that they rarely fail).
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.

I bought a new unibody Macbook around 4-5 months ago and I've generally been very impressed with it. It's my first Mac and considering all the problems I'd had before with Windows PC's, it's quite a relief.Anyway, here's the issue. When hooked up to my 24 inch Dell monitor there are numerous problems. Originally it just started with the screen intermittently turning itself off and on, and there being a sleep/wake issue. I did some research then and discovered that this was by no means a problem confined to me. Knowing this I was prepared to wait until Apple fixed it with a firmware update or something, as the problem was annoying but not devastating.
However since then the problem has got significantly worse. Not only are the screen flickering, sleep wake/issues occuring much more frequently, but there are other problems. For instance, the menu bar and the dock sometimes fail to show, and I've been having a very weird problem with the Logitech mouse I use. Even though I can move the cursor generally I can't click, and when I can, only the right mouse button works.The same is true with the trackpad, so it's not a problem with the mouse.
When these problems occur the system generally seems to be very slow. I've checked the 'activity monitor' and the use of 'system memory' seems to be very high. For instance, at the moment (I'm using my Macbook by itself) I'm running a few applications (Mail, iCal etc.) and I've got 1.09 gb of free memory. Last night I was running exactly the same applications and I must have had less than 0.4 gb of free memory. The pageout numbers were fairly high as well.
It's strange because when disconnected from the external monitor the Macbook seems to work seamlessly. I just don't understand how some of the problems I've experienced (such as the mouse issue) can arise from problems relating to the external monitor setup. What do you think? Should I be worried that these issues are perhaps indicative of a greater problem? Either way, the problems are becoming hard to deal with. Very disappointing.
After upgrading to snow leopard my charger works intermittently, could this be a software issue or just a coincidence

This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).
My Macbook is only about a year old and the tab key, the numeral one key, the tilde and screen brighter key (not the dimmer key) have all stopped working well. They are non-responsive for about ten minutes after I open/start up, and then start working intermittently once the machine has warmed up. I clean the surface of the keyboard regularly and none of the other keys seem to be having a problem.

MacBook Pro 15" Late 2011 (Mavericks 10.9.4); 4 GB ram. I am running HDMI to a new video projector. The HDMI signal is lost periodically for about 1-2 seconds and then comes back. It occurs about every 5-7 minutes (about 20 times during a 50 minute lecture). It loses both video and audio. Screen goes black but no displayed messages. I have read a variety of other posts with similar symptoms with various computers (e.g. Mac mini) and even with DVI cable use. In my case, I've used two different HDMI adaptors so it's not the adaptor. I'm pretty sure it's not the HDMI cable itself. (A fellow professor does not have the issue with his PC and he uses the same equipment.) Neither the computer nor the cable is touched. (I have another colleague who reports the same symptoms in his music lab.) Bottom line is that it's a distraction to my students and it's occurring off different Macs in different locations. This means to me that it may be something with the particular generation of Macs we're using.
