Apple MacBookPro 2010 is in a white screen


If the start up sound plays and the hard drive sounds normal try connecting the computer to an external monitor. If the external monitor shows the desktop just fine then the cable connecting the laptop to its screen is probably going bad.

If the computer will not boot at all try zapping the PRAM by
  1. Pressing the power button and then command-option-p-r before the gray screen comes up.
  2. Hold those keys down until you hear the startup chime.
  3. Let go of the keys and let the Mac reboot.
If that doesn't work try booting from an install disk and run a repair utility.

Hello.

You'll need to reset the iPhone.

From About:

To do that, hold both the sleep/wake and Home buttons together for at least 10 seconds.

The red shut down slider will show up at the top of the screen and then disappear. Keep holding the buttons. The screen may even go black, but don't let go of the buttons until the Apple logo shows up. When it appears, let the buttons go and the phone will start up normally.

Hope this resolves your problem.

My 21" mid 2007 imac periodically freezes, the


Try booting it into single-user mode holding down Command(Apple) and S buttons when powering up. Then in terminal console, use chkdsk -fy. Use it and use it again until comes back with something like "Volume appears to be OK". Then use command: mount -uw / and then type reboot and try booting normally.
If it does not fix your problem, it's most likely a hardware issue (logic board / graphics card), and you should take it to an Apple Authorized Service Provider.

I got this imac desktop computer model # m6498 from my aunt. when i turn it on it shows a spinning loading wheel and i cant get pass that page...How do I fix this?


Luck you, hopefully we can get this fixed! Ok, there are a few things that might be causing this, and several ways of dealing with them.
Firstly, if you're not fussed about saving the data already on the computer, try the following:
  1. Turn the Mac on and insert the restoration disk that came with it (If you don't have one then you'll need to get one, try ebay or amazon, or an Apple store).
  2. Turn the Mac off with the disk still in
  3. Re-boot it, holding down the C key. This will boot up from the CD, and hopefully you'll be able to re-install Mac OS X, which will give you a working, clean machine.
If that doesn't work for any reason, I'll need some more information. Try this:
  1. Turn the Mac off, after ejecting any CDs.
  2. Boot up your Mac, and as soon as you press the power switch, hold down Command and V. This boots up in verbose mode, giving you more information about what's happening in the computer.
  3. Watch the instructions on the screen, and see if there are any obvious error codes, or if there are any instructions that the computer gets 'stuck' on.
If there are any error codes or sticky instructions, please post them back up here and I'll see if I can help some more.
Hope that was helpful, good luck!

It sounds like you may have disconnected during a restore

Try getting the iPhone into recovery mode.
  1. Turn the device completely off and disconnect it from cable/dock.
  2. Hold down the home button.
  3. While holding down the home button connect to a computer with a cable (easiest) or dock.
  4. Keep holding down the home button until you see a connect-to-itunes screen You are now in recovery mode.
If this fails try holding the power in home button at the same time A LONG TIME about 2 mins the phone will boot and reboot until you see a USB cable and a disk on the screen. Just keep holding.

The connect to iTunes and restore.
