Macbook help - power keeps cutting out for no reason - please help

my macbook will sometimes just randomly turn off even though i have full power or enough power to run.
if i try to turn it back on it will just go off again unless i let it 'rest' for a bit, maybe five minutes.
then it will just work again and i'll eventually enounter this problem again from an hour to two days later
at the moment it's annoying as the worst that has happened is my work not being saved (word recovers the document anyway) and this happening multiple times when i was trying to import a cd.
although just annoying, i fear it could lead to something worst.
please help

Since you are having random shutdowns, and you mention that you have to wait awhile to turn it back on, I suspect that the computer is overheating and shutting itself off. The computer is then waiting until it cools down enough to allow you to turn it back on.
This was a fairly common issue when the macbooks were first released. Apple released a firmware update that resolves this. The firmware update improves the computers internal monitoring system so that the fans kick on earlier and prevent your computer from getting to the point where it shuts down due to thermal issues.
As previous posters have already suggested, go to the apple icon in the upper left hand corner of your screen and select "software update." Install any firmware updates that appear. Please note that the firmware update may not appear in this list of updates if your operating system is not 10.4.6 or higher.

Satellite L755D - sound keeps cutting out for no apparent reason

I posted this in another thread, but thought I might need to start one of my own since a solution had been found by that person and I am still having a problem. So, about three weeks ago the sound on my computer began just cutting out for no apparent reason. It happened while I was watching streaming video and I tried updating all my software stuff (like flash and java and things of that nature). It still continued to happen and now it was happening with streaming video, with youtube type videos, and with mp3s stored on this computer. I discovered that if I went to the control panel and clicked on sound/hardware and then clicked on the tab for recording, the sound immediately came back. So, I've been doing this for the past couple of weeks and it is extremely annoying! In another thread on ths forum, the individual discovered that the Malwarebytes program had been the culprit and I was happy to have an answer, except that I had installed security software last week which removed MB from my computer. And I continue to have the issue even today. I clicked on the link in the other thread to update my drivers and I continue to have the issue. Can anyone help? It's making me crazy! Thanks in advance.

OK - I'm getting this as well. Satellite L750-1E5. It was fine for ages and this started happening about a month ago now. - tried updating the drivers - System restored back to when it worked, not working This led me to think it was a hardware problem. My gut feeling however was that it was some sort of driver problem as sound would cutout after about 2 minutes, but would often come back if I started playing another song or something. Reinstalled Windows 7(64 bit) and played through an entire song with no issues(using Windows 7 sound drivers). Ran Windows update and the issue has come back. Installed the proper Conexant driver, but issue still occurring. I believe a Windows update has caused this issue.

TV keeps cutting out for anywhere from 2 - 20 seconds

My TV service cuts out arbitrarily (screen goes blank) for anywhere from 2 to 20 seconds. Tends to happen more often and more frequently in the evenings. It is occurring both on my HD-DVR box as well as my standard STB. All the boxes are Motorola. Any ideas. This started about 6 weeks ago and is getting really annoying.

that is usually an HDMI issue, so that is either coming from the TV, the Cable itself or the Box.
you can try resetting the box first, and see if it goes away.
Menu > Customer Support > in home agent > reboot STB.
If that doesn't work, you can try power cycling your TV, just unplug the TV for a few minutes, and then plug the TV back in, see if it goes away. re
And you can try reseating the cable (oddly this works) just unplug the cable at both ends, plug em back in. Or try switching the port on the back of your tv (the set top box only has one HDMI your TV may have several to plug into)
And you can try changing the cable itself.
If all that doesn't work, then then call into customer service and see if they have any tricks up their sleeves, they sometimes have special reset commands that are a little stronger than simply resetting the box. they may have to replace it if all else fails.
if you plug in a different cable like Component it will probably go away, and you will preserve the High Definition Picture quality.

Wireless Internet keeps cutting out for a few minutes

Hi,
I have a WRT160N router using DSL and PPPoE, and my internet continually cuts out at most every 15 minutes or at the least once an hour. I thought it had something to do with security so I changed from WPA to WEP but that didn't do the trick. It is almost as if it has to restart itself but that shouldnt happen. What can I do to fix this issue.
Please any help would be greatly appreciated
Thanks

Hello
To get a better handle on the problem, connect at least one computer to the router using an Ethernet cable. This can help isolate the problem further.
You can pretty much connect as many devices to the wireless side as you wish. The only problem you might encounter if you connect a large number of machines on the wireless side is lack of bandwidth. I can't imagine 5-6 machines on a wireless network would be a problem, unless one or two of them attempts a large file transfer. Even then, I would expect the wireless to be slow - not down.
What version of firmware is in your WRT160N? How long have you had your router, and has it worked properly in the past?

Delete your account in 1. "Settings > iCloud" + 2. "Settings > Messages > Send & Receive" + 3. "Settings > FaceTime", but still let them using your account for iTunes and app purchases in "Settings > iTunes & App Stores". Of course, please make sure that they do not know your password to set up your account for iCloud again or purchase anything alone.

Trouble starting up for various reasons, please help!!

Hello, I have a macbook pro, and am having some really strange trouble with it.
First, it was telling me my password was incorrect, which it absolutely was not. THe only way I can be so sure of this is because I was reformatting my iPod, and in doing so, it asked me to enter my password to grant permission for the reformatting, which I did, and it worked fine. shortly after wiping the iPod, my computer died. I came back to it, and booted it up to the login screen - at this point in time, it was refusing to accept my password as correct. I tried caps lock, no caps, tried to let it die, restart, etc. etc.
Eventually I was led here, where I found a series of posts with the same problem, and one suggested to type in a script through terminal before the computer was fully booted. It was basically a script to access the password keychain, and update it from there. I put in the script, and restarted my computer. However, this time, instead of going to a login screen like it normally does, it went to a language selection screen, similar to the one you see when you first install the OS. So it prompted me "please select what language you would like to use this software." I clicked English, the dialog box went away for a moment, just to pop up again, and this is where i'm at now. Over and over it will continually just revery back to this screen, not allowing me to do anything.
So this is where I need your help. My CD drive doesn't work, or else I would have just booted from my disk. If there's anyway I can avoid formatting my computer, that would obviously be the more desirable route. To make things perhaps more complicated, i'm not entirely sure which exact operating system I am running, which i'm sure doesn't help. Although I believe it's Snow Leopard.
PLEASE HELP!!

you do not want to install the operating system at this point anyway. i hope that this is the 10.3 (panther) install disk you are booted too. very bad if it isn't. go up to the installer menu and select "open disk utility". then see if the macintosh hd is visible there. if so, select it, and then "first aid", and then "repair disk". if it is not visible, reset the pmu http://docs.info.apple.com/article.html?artnum=14449 (your model should be listed there for instructions) and try disk repair again. let us know how it is going.

My computer randomly logs me out for some reason. Help?

It happens sometimes when I'm chatting on RockMelt or AIM, but that's not really significant since I chat with people all the time on those services without having problems. I tried repairing my disk permissions and thought the problem was solved, but apparently it's not because it's still going on. Could it be a background process I don't know about, could I have a virus, or what?

Launch the Console application and look at the file list on the left side of the window. Under System Diagnostic Reports, you will see one or more crash logs for either "WindowServer" or "loginwindow." Post the most recent one.
By the way, despite what you read in these forums, repairing permissions is a waste of time unless you have a specific indication of a permission error, which you don't and probably never will.
There are no known Mac viruses. Mac malware does exist, but it doesn't cause the kind of problem you're experiencing.

Audio keeps cutting OUT !!

Hi All
I've just recently started having problems with the audio signal from my MP, all applications like iTunes and listening to streamed radio online. I'm using a 828 Mk1 firewire audio interface and the audio keeps cutting out for a 2-5 seconds frequently. I'm using the 1.4.7 motu driver, clock source is Internal. There doesn't seem to be a problem if I use the Macs internal speakers. Its been working fine since I got this machine a few months ago but all of a sudden this problem has occurred !
Anybody have any ideas to what is happening here ??
Many Thanks

hi MacMac,
i did reply on your other thread:
http://discussions.apple.com/message.jspa?messageID=7189792#7189792
i had a fiddle with sample rate settings, both on teh motu itself, and in the midi utility ,and installed the 1.4.7 driver, and mine seems to be sorted as of today too.
weird, huh?

After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolution from the community, but hope to get the attention of Apple engineers. If you are having same problems or have a miracle cure I am all ears.

May start my own thread, but I'm having similar issues.
I've been using an old iMac (running 10.7.5) and Apple TV for years with no issues. Last week I bought a new Macbook Pro running Yosemite and have had audio issues multiple times. The weird thing is that sometimes it works flawlessly, other times (like now) I spend half an hour just trying to get a song to play.
My issues are: When I got to "computers" in Apple TV to stream my music, my music is sometimes chopper or intermittent, and I seen to know when it's going to happen based on the status wheel just before it plays. When I choose a song, the status wheel will spin for an unusually long time, usually an indicator that the audio is either not going to work, or stutter.
When it does finally pull up a song, the playhead sits at the beginning of the song for a good 3-5 seconds before actually playing. Then, when it starts playing, it's all downhill. It will play a few seconds, drop out, play a few more seconds, drop out, and then ultimately the playhead will keep moving across the song as if it's playing, but there's no audio.
Again, this is a new phenomenon never experienced by me. I've tried everything I could think of, some of them all at once:
• restart Apple TV
• restart Macbook Pro
• quite iTunes/open
• turn off Home Sharing on iTunes then reconnect it
• unplugging and cycling both my modem and router
None of these have alleviated the problem.
The odd thing is, like this morning, the audio started up perfectly and never gave me any issues. It wasn't until later in the day that it started. Perhaps after the macbook pro had been put to sleep? Not sure.
Regardless, this is an annoying trait, one that's new to me and my system (as stated, worked flawlessly until my new purchase), and is 100% limited to either a) the macbook pro b) Yosemite or c) both of them.
