Question about Computers & Internet

My eMac will not turn on. I had it in the "sleep mode" and there was a short power outage in the Los Angeles area. Later when I came to my Mac, I couldn't get it to turn on. Is there a fuse that's replaceable or a reset button that should be pressed? Please help. Thanks, Reggie

Hi!

There is a power supply failure, please check the power supply--

  • Step 1: Plug the PC into an electrical outlet rather than relying on a battery to power up the system.
  • Step 2: Eliminate a faulty electrical cord as the culprit. Examine the cord that runs from the PC to the wall outlet. Determine whether there are any indicator lights within the cord itself to identify functionality. If there is such a light and it is not lit when plugged in, the problem may be with the cord and not the PC.
  • Step 3: Try to turn the PC on. To diagnose the internal power supply as the culprit, it is essential that there be no sound or monitor activity whatsoever. The PC needs to be completely dead.
  • Step 4: Unplug the PC.
  • Step 5: Open the PC.
  • Step 6: Identify the power supply. It will be a metal box containing a power cord receptacle (where you plug in the PC's power cord) and a small fan. It is usually located in a corner of a desktop PC.
  • Step 7: Remove the power supply plug from the motherboard.
  • Step 8: Insert a paperclip into the terminals (usually colored black and green) of the power supply plug.
  • Step 9: Plug the PC directly into a wall outlet. Do not use an extension cord.
  • Step 10: Press the power button on the computer.
  • Step 11: Examine the PC fan inside the power supply to see if it is spinning. If it is not, then you have diagnosed a failed power supply.
  • If, after you remove the power supply plug from the mother board, insert a paperclip into the plug's terminals and press the power button, the fan inside the power supply does spin, the problem is a failed motherboard rather than a failed power supply.

The eMac's power supply is NOT auto-switching. The popping sound you heard was the power supply blowing out. Hopefully it will turn out to be just the internal fuse that's part of the power supply, and not the power supply itself, let alone the logic board. Just how bad the damage is would depend, I suppose, on just how fast that particular 'fast-acting' fuse actually is the problem.

If your computer won't turn on, try each of these steps:

  1. Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
  2. Make sure that the power adapter is properly connected to the power port on the back of the computer.
  3. Disconnect all accessories that are plugged into the computer, such as a printer, hub, or iPod.
  4. Reset the computer's PMU or PRAM.
    • For a portable (iBook or PowerBook), click here for instructions.
    • For a Mac mini, click here.
    • For an iMac, click here.
    • For a Power Mac, click here.
    • For a Mac Pro click here.
    • For a MacBook or MacBook Pro, click here.
    • For any other computer, click here for instructions on resetting the PRAM.
  5. Try plugging a different power cord into the computer (if you have a working one available). If the computer starts up, replace the old power cord. You can get a replacement cord for some models here.
  6. If the computer uses a power adapter, try connecting a different power adapter to the computer (if you have a working one available). If the computer starts up, replace the old power adapter. (Computers that use a power adapter include MacBook, MacBook Pro, iBooks, PowerBooks, Power Mac G4 Cube, and Mac mini.)
  7. If you tried all of the steps above and the computer still won't turn on, contact Apple technical support (1-800-APL-CARE in the U.S.) or take your computer to your local Apple Store or Apple Authorized Service Provider (AASP) for diagnosis.

Try resetting the SMU (system management unit) it specifically addresses startup problems with the iMac G5:

Unplug your mac for 5 minutes, also disconnect the battery if this is a laptop mode. After 5 minutes plug it back in and try turning it on.

Prostart 6 button in sleep mode


Sleep mode is a convenient power-saving feature used on both laptops and desktop computers. This feature powers down hard disks, monitors, wireless devices and any other power-consuming peripherals without turning the unit completely off and necessitating a reboot. Sleep mode can prevent battery drain if using a laptop or mobile device while away from the power supply. This mode is useful when quick access to a computer is needed, but can be irritating if the sleep mode takes a long time to come back from. It is simple to turn sleep mode off, based on the operating system being used.

Go to the "Start" button, then click on "Control Panel." In the control panel screen, click "System and Maintenance," then click on "Power Options." This brings you to the "Select a power plan" page. From the "Select a power plan" page, select the option that says "Change plan settings." This changes the settings on the currently selected plan. Select the "Change advanced power settings" option. Click "Sleep" and then click on "Sleep After" to expand it. If using a laptop or mobile PC, click "On battery" and "Plugged in," then select the "Never" option. This turns off sleep mode for both battery and AC use. If you are using a desktop computer, click "Setting," click the arrow and then click "Never" to turn off sleep mode. Click "OK," then click "Save changes" to save the modification. b> Turning Off Sleep Mode - Mac OS b> Click on the Apple logo at the upper left corner of the screen to open the menu and select the "System Preferences" option. From the "System Preferences" screen, click on "Energy Saver." If you are using a desktop, select "Power Adapter" in the top drop-down menu. In the second drop-down menu, select "Custom." Highlight the "Sleep" tab, then adjust the top slider to the far right, marked "Never." I f you wish the display to stay on, adjust the bottom slider to "Never." Click the red button on the upper left side of the "Energy Saver" screen. If you are using a mobile product or laptop, follow step 2 and select "Battery" from the top drop-down menu. Repeat step 3 to change the settings for battery use. Hope this helps.

How to get out of sleep mode?


You turned the laptop on and off and it still is asleep?

When you turned it off did the power go completely off? If not remove the power cord to make it go off.

Try booting up into safe mode and see if it goes to sleep.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity so you can view the manual later) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. Check your Power Options in the Control Panel to set your Sleep Mode and Hibernation up higher or set it to NEVER. Click Start/Control Panel and look for Power Option (it might be under System and Performance).


Below is a link to your user manual. You want to go to Pages 77 and 78 where it talks about changing the Power Plan. You want to select Change Advanced Settings as it talks about on pages 78 and you will be allowed to change the hibernate and sleep settings.

I have a Area 51 Desktop with a i7 930 ans 2 hd5870's it turns on but no video or no beeps any ideas? was working fine left it for the night went into sleep mode and then no video


Some Vista and Windows 7 PC's have had issues coming out of sleep mode due to hardware problems. Try holding to power button for 5 seconds or so to force a shutdown, then power on as normal after a minute or so off. THIS WILL LOSE YOUR CURRENT SESSION AND ANY UNSAVED WORK! You have been warned :P
Best of luck!

Hi there, it appears as though the Power Options are set too short a time and the PC is going into sleep mode. Go to Start menu/Control Panel and look for Power options. Set them all to "never" This will prevent her PC from going into sleep mode. Good Luck.

Sleep Mode Lockup on Dell Inspirion 530 w/ Vista


Try hitting the "Windows" key on your keyboard to bring it out of sleep mode. The "Windows" key is generally found on the bottom row of the keyboard, near the Alt and Ctrl keys, and it has no letters on it, just the Windows logo. That key brings my Windows Vista machines out of sleep mode when other keys won't.

As for the power button, anytime you need to force a computer to turn off, you can press and hold the power button to do so. Usually, you need to hold the power button for 5-10 seconds and it will shut down. Use this option with caution, as it turns the computer off without running through the shutdown process and can cause you to lose data.

Hope this helps.
