  • Computer is on but screen is dark.

    While using computer (in Aperture) screen went dark. Computer sounds like it's "ON" but lights are out. I tried restarting with the button in back, unplugging/replugging in, holding down startup button for many seconds, tried the Command-Option-R-P trick after pressing startup button, but nothing works. Help!

    Hi Maria,
    If your iMac appears to be booting but you don't have any video, you may want to take a look at the troubleshooting steps in the following article:

    imac turns on but screen stays black ? i can hear it operating ...

    Hope this helps:
    As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...

    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    It is the 5 second timing that initiates the reset.

  • My macbook pro will turn on but screen stays black.

    My macbook pro will turn on but screen stays black. There is no sound on start up and keys dont light up. I have done all the resets:
    I disconnected the computer from the power cord, and from all other cables.
    I held down the power button for several seconds to turn off the computer.
    I let it sit 5 minutes.
    I restarted the laptop while holding down the Shift key and nothing happened.

    I need lots of help!!! any ideas? Its a MacBook Pro 15” or 17.5” about 5 years old. Its about 2 updates behind (OS: Snow Leopard)

    Zane W is giving you good advice.  Take it to an Apple store genius bar and have them examine it for free.  You then will know what the issues are and then can make informed decisions.

  • Pavilion g6 turns on but screen stays off

    My laptop screen will not turn on. I hear the laptop itself turn on but screen does not turn on. This is the second time within a year that I've had problems with this laptop. I've tried the hard reset and tried powering it up without the battery and just the power cord and nothing. Please help! I'm lost on what to try next.

    Hi @sanaa0415 
    Please post the full product number for your notebook. See the following, if you need help with that information.
    How Do I Find My Model Number or Product Number?
    Is there any sign that the display is getting power, a slight flicker, or a bit of backlighting, to indicate the display is powered?
    Do you see anything on the display at all during startup, such as error messages?
    Was there anything done to the notebook just prior to the display going out on you? Software or driver updates, new hardware, or anything accidental.
    For now check out these pages and see if anything changes.

  • TS1367 My charger connects with my macbook with a very faint green light (not the normal orange light) and can maintain the computer turned on but does not charge the battery.

    My charger connects with my computer with a very faint green light (not the normal orange light) and can maintain the computer turned on but does not charge the battery. The power source to keep it on is the power adapter and that it's "Not charging" on the battery settings. And my charger seems to charge other computers fine.
    The part of my mac where the adapter (L-shaped, magnetic) attaches is a bit damaged - a small piece of the white case/body around the part where the adapter attaches is broken off, but that's just an outer damage.
    I don't know what's wrong with my computer, and if anyone has had a similar experience or knows what's going on, it'd be tremendously helpful!
    Thank you!!

    Hi Christopher,
    Doubtful an upgrade would fix a hardware issue. If you are thinking of upgarding to Lion, best to do all necessary maintenance first.
    Try Resetting the System Management Controller (SMC)

  • Half of screen is dark with distinct line between dark/light

    half of the screen is dark with a clear line between dark/light visible.

    If you haven't done any trouble shooting then begin with restarting in Safe Mode and if that doesn't work reset (may need to do each 2-3 times) both the SMC and PRAM. Finally if that doesn't work run Hardware Test in Extended Mode (again 2-3 times) to test for hardware issues.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • IMac display turns off but computer doesn't sleep.

    After upgrading to Mavericks I've noticed a problem where my iMac display will turn off but the computer will never enter into actuall sleep mode, I know this because I can constantly hear the fan humming. I have the Energy Saver settings set to sleep the display after 10 minutes and sleep the computer after 15 minutes. However even well after 15 minutes of inactivity (and the display long having turned off) I can still hear that the computer is not sleeping due to the fans still being on.
    I decided the troubleshoot the problem using a Terminal command and I was able to narrow it down to single potential cause. According to "PreventUserIdleSystemSleep" the problem stems from a "URLConnection in progress" issue. How does one go about determining what is causing the URL Connection so I can kill the prompt and see if that solves the sleeping issue?
    Here's a screen shot of the Terminal output:
    Also, if I choose "sleep" from the Apple Menu, the iMac will go to sleep as normal (fans and harddrive sleep).

    Reset the SMC and the PRAM.

    • Shut down the computer.
    • Detach the computer's power cord.
    • Press and hold the power button for 5 seconds.
    • Release the power button.
    • Reattach the computers power cable.
    • Turn on the computer.
    Reset the PRAM
    • (Re)start the computer
    • Immediately press & hold the CommandOption+PR keys
    • Wait for two startup chimes
    • Release the keys and allow the computer to boot.

    Hi Josi86, 
    Welcome to the Apple Support Communities!
    I know that it is both frustrating and concerning when your computer does not start up as you would expect. In this situation I would recommend working through the troubleshooting steps and information located in the attached article.

  • Computer turns on but nothing appears on the screen

    Hi,
    I have had this desktop computer for about 2 years. I usually use it almost daily and turn it off at the end of the day. Every few months or so the computer would turn on but nothing would appear on the screen. I would have to hold the power button to turn it off then turn in on a couple times or wait until the next day and the computer would turn on and everything would appear on the screen and work perfectly. Last week, the computer once again turned on but nothing appeared on the screen, except this time, after a week, the computer will now turn on except there is still nothing appearing on the screen. I no longer hear the fans running, however, I hear everything else running as normal. I have unplugged and re-plugged in all the cords multiple times and still, nothing.
    Please help! Thank you.

    Kelly, welcome to the forum.
