Reset, hold both home and power buttons until the iPhone begins to start, try this a few times if necessary. If still problem, you may have to just Restore your iPhone to get it working. In the future sync your iPhone with iTunes routinely and when it contains important data, iCloud when set correctly will do this for you continuously.

If it's stuck in there you might have to make a "guide" out of two thin pieces of plastic. Post back if that's the case.

The router might be bad or incompatible, but let's be optimistic.
On System Preferences, go to Network/Advanced/PPP. Only two items should be checked: Connect Automatically When Needed and Disconnect when switching user accounts. Uncheck everything else. Now, click Okay on the end of the page. The next time you're online, you shouldn't be disconnected.
If you still get disconnected like before, we might be dealing with a router issue - which can get rather complicated.

Mac Book Pro not working replaced logic board

Hi all,
My Mac Book Pro died on me about 2 weeks ago. I was using it like I normally do and then suddenly an error message came up on the screen and a white transparent screen came from the top of the screen to the bottom. Then it shut off. After that we tried resetting the PRAM and tried booting it from a Snow Leopard disk. The machine won't chime. It does spin a disk in the drive though, but there is no video either.
I brought it in to an apple store and they said it was the logic board. I purchased a new logic board , installed it and the symptoms are the same. Does anyone know what the problem could be?

I have a digital voice recorder with a 3.5mm mic and headphone jack and want to transfer some recorded lecture to my mac book pro. The mac book does not have 3.5mm jacks. Does anyone know if a jack to USB converter would work?

I have a digital voice recorder with a 3.5mm microphone and headphone jack and want to transfer some recorded lectures to my mac book pro. The mac book does not have 3.5mm jacks. Does anyone know if a jack to USB converter would work?

Is there a pattern to the time of day or other detail that may be
traced back to a OS X system cause of this odd phenomenon?
Are there any copies of system files on any of the attached USB
external drives? Any libraries, such as iTunes, iPhoto, etc?
Once the drives are indexed by Spotlight, are their permissions
ignored by the OS X? Content, if neutral, should not affect the
wake or sleep cycle; especially if they're ignored by the OS X.
Could there be a bad cable or other component? If so that would
be a difficult process of elimination to detect it. Usually replacing
most suspect components in the USB stream (external to Macs)
is a rote way to mechanically test that idea; & not 100% sure.
Does the equipment all have a good ground to the utility or house
electrical field? An intermittent ground may affect more than sleep.
Hard to say at this point. Maybe a late-night talk radio guru on
remote viewing could peer into your situation and sleuth it out?
Sorry to have run out of ideas, but the process must be electrical
& mechanical to some extent. - Or perhaps odd software inspired.
Do you have any phone-home spyware items inside, just jumping
at the chance to spill your information? Little Snitch may help.
PS: Perhaps the computer needs to go into Apple & have a genius
or product specialist at AASP test the unit thoroughly... BlueTooth?

The Volume on my Mac pro is not working. I can't raise or lower the volume and sometimes it mutes by itself. additionally, the speaker button on the top right is garbed out.

Mac headphones jack not working

When I plug in my earbuds into my mac, it does not work. The sound keeps playing through the internal speakers and no sound comes out of the earbuds. I have Apple EarPods and they work on my phone and every other device but my mac

Try other earphones to see if the fault lies with the audio output port.
You may try a NVRAM reset:
