Mac book pro speaker sounds vibrating when volume increases

mac book pro speaker sounds vibrating when volume increases

Is there a red light coming from the headphone socket ? If so it's got 'stuck' in Digital Audio mode.
Try inserting and removing a headphone jack while wigglingit a bit - inside the socket is a small switch that can tell the difference between an analogue plug and a Toslink (digital) one - sounds like the switch is stuck in the wrong position ...

Try Resetting your Mac's PRAM and NVRAM
If that doesn't help, try Resetting the System Management Controller (SMC)
If nothing helped, since you don't hear the startup chord, make an appointment at an Apple Apple Genius Bar or take your Mac to an Apple certified repair provider.

If that doesn't it, then do a #2 PRAM reset and try the above again.
..Step by Step to fix your Mac
If no OS X boot volume appears in Startup Manager, then OS X is corrupted.
Try more of the Steps above (like 1-8) then if that doesn't work.
Create a data recovery/undelete external boot drive

Screen on my Mac Book Pro goes out randomly when I touching trackpad.

The screen on my Mac Book Pro goes out randomly when I touch my trackpad. Every time the screen shuts off, I have to restart my computer so the screen will turn on again and it's driving me nuts.
Does anyone have any idea why this is happening and a solution?
Thanks
Kevin

You can blank the monitor using those keys, that's likely what you did, it's a feature.

Mac book pro speaker

Mac Book Pro 17" CS6 crashes when setting output to second monitor.

I am testing out the trial version of Premiere CS6 and the program keeps crashing when I try to set the video output to my second monitor via a DVI connection. Anybody else having this problem with the Mac version?
Mac Book Pro 17"
2.2Ghz I7
8 GB
AMD 6750M 1025MB

I am using a mini display port to DVI adapter and it is a thunderbolt port.
I just tried it again and now it seems to be working. I have tried it dozens of times and everytime it would do nothing and when I opened prefrences to change it back CS6 would lock up.
I just tried it a couple more times by closing the program and openning it up again and now for whatever odd reason it seems to be working great.
I also have been trying the trial version that was released last week but I have since removed that version since it wasn't a stable release but it had the same problem. I am using the official trial version as of this morning and the problem was still there but now it is gone.
Not sure what happened but no matter what I do it now works. huh Perhaps a left over preference file from the unstable version or something like that.

Why does my mac book pro screen go black when it goes to sleep and then will not light up again unless I unplug the power cord

When I either leave my mac book pro open, but idle long enough for it to go to sleep or close the top and put it to sleep, the only way to light up the screen again is to diconnect the mag. connect power cord. Any ideas why and/or how to correct this problem?

So this is what I got when I took my computer into the apple store to have it diagnosed.
After the apple technician performced several tests, the only thing that fixed the issue was an SMC reset. Based on this he figures it is probably a software or firmware issue that is going on. He is a little concerend how ever that the fans of the comupter don't reach maximal rpm when the computer is displaying the issue. So he recorded the problem, and told me to just perform the SMC reset as needed for the next couple months and wait for a new update from apple. If the issue persists I am to go back to the apple store and they will take the appropriate steps.
He said an SMC reset doesn't hurt the computer in any way, so its safe to do. I am gonna contact blizzard and let them know about the issue as well because if it is software, it could be their game (Diablo 3) that is causing the issue as well. If I hear of anything new i will let you know. So get on the blizzard form and let them know of the issue to fix the problem faster.
Thanks for your help,

My Mac book pro pauses and choles when playing video files

Hi guys.
I have a mac book pro 13 months old. I have been using it successfully with final cut studio 2 for a while now. But now it will not play vdeo files without choking all the time. This is with all applications like a canvas in FCP, a QT movie, even avi files when viewed in movie maker on paralells. I have done a sweep with "OnyX" but no improvement.
I have empties the trash even.
Can anyone help?
PS the only way I can view video files is after they have been converted through flash to flv and then viewed in th "mpeg streamclip" application.

My mac book pro keeps dropping calls when skyping. I skype regularly with one person and they told me that more calls get dropped with me than with anyone else.

When skyping, my mac book pro keeps dropping calls. Apparently, it's the worst with my computer according to those I skype with. Please help!

What did Skype support say when you asked them about this?

Mac Book Pro won't wake when its been charging.

I have had this problem for some time now. When I charge my Mac Book Pro over night. The next time I use it, It won't wake up for sleep mode and I have to restart the computer. Was wondering if there has been problems with this too. If so is thier a fix for this. I'm running MacBook Pro (mid 2012) with Retina display, OS X Mavericks (10.9).

This is a BUG in Mavericks and or the Mac hardware. It goes into Standby mode after an extended period of inactivity and then Crashes when trying to come out of Standby mode completely Hanging the system and making you have to Restart it.
There is quit a long thread on this subject.

My mac book pro wont charge even when plugged in what is this most likely to be, my mac book pro wont charge even when plugged in what is this most likely to be

my mac book pro wil not turn on even after being plugged in all day, the light on the charger is on a very faint green but will not power up, if anyone else has had this issue please let me no what it was, it could be the battery although my partner seems to think its the little black box the wires go in and out of
Cheers
Lee

First try resetting the SMC.

If that doesn't do it, the best thing would be to take it to the Genius Bar for a free eval. If you can't, best guesses are:
1. The battery
2. The charger
3. The internal board that the power supply connects to.
What little black box?

Xperia Z1 vibrating when volume increase

Hi Z1 owner,
Did you feel the phone is vibrating when you increase the speaker phone volume. Example when playing games, or playing music or movie, after increasing the volume to about 70%-100%, you will feel the phone is having slight vibration. Is this a common issue for Z1?

Are you certain its not the volume/speaker itself that creates this "vibration" ?

I am using a mac book pro with Leopard OS. when I switch my laptop on it flashes a grey folder with a question mark on a grey screen, after the chime. I have tried all the things mentioned in another discussion. none of those have helped. HELP! im scared.

what must i do? im a student and dont have backup for my work. Im in desperate need of a solution where i wont lose my work from my desktop.

You need to purchase Leopard if you don't have the DVD and reinstall OS X:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
