My power button is flashing (white) and I have no video, no beep, just rapid flashing

The power button on my mac pro is flashing (white) and I have no video, no beep, just rapid flashing.

"Almost all flashing power button at startup problems are caused by RAM issues."
Wow, how a simple search here saved me a lot of time, THNX!!
One of my 8 Transcend 2GB 800 MHz DDR2 FB-DIMM RAM modules caused this fault. Strangely no red led on any of the 2 RAM trays, so I had to trial-and-error all modules on each of the two RAM trays to find out wich module broke on me.
Cheers

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

The computer usb port will not charge it. Plug it into an outlet with the charger that came with it for a few hours & try again.

There is nothing wrong with your Dell, it will work fine with any MacbookPro. I have been using Dell displays for over 12 years with many different Mac models. I have two 21" Ultra Sharp displays working side by side to design a Keynote presentation right now.
The issue your having is with the way Keynote takes control of the video output to both displays, it sends the presentation signal to one and the presenter display to the other, this is set up in;
Keynote preferences > Presenter display.
If you want to show a wesite or another app on either display, use application switcher:
press the the command key on the keyboard, then the tab key; a row of applications will show what applications are running, choose which one you want to show. Use command > tab to return to Keynote.

My power button is not working and my phone doesn't wanna turn on i've tried to charge it so it can turn on like it usually does but it's not turning on

my power button is not working and my phone doesn't wanna turn on i've tried to charge it so it can turn on like i usually does but it's not turning on

Hold down on the home button simultaenously holding on the sleep wake button (power button) hold it for more than 15 seconds this will then shut down the device.
If the device is already shut off do this same sequence to see if you get an apple logo. If you get the logo allow the device to login. Write back if this does not resolve your issue.
Good luck Friend.

The warranty is not and has never been International. Warranty and support are only valid in the country of origin. The only exception is for devices sold in the EU where the EU is treated as one country for warranty and support purposes.

If you've had it for less than a year, then it's still under warranty. Take it to an Apple store or an authorized service facility. See http://support.apple.com/kb/HT1434

Hi, Gary. Welcome to Apple Discussions.
It sounds like you may be having logic board problems. Enough Dual USB G3 iBooks suffered from the logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Do the symptoms look familiar? After leaving it sit overnight, does squeezing the case to the left of the trackpad allow you to start up and work for a bit as long as you keep the pressure on it there? If so, you may want to consider trying the shim fix suggested by John Sawyer in the Apple Discussions iBook G3 (Dual USB) Displays Forum:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.
John Sawyer
CJS Macintosh Repair
Instructions for removing the lower case:
iFixit.com
If the shim fix doesn't work (or you're leery of trying it), DT&T Services in Fremont, California offers the cheapest repair I've found. They have a six-month warranty on the repair.
Once you get it fixed, try never to pick it up by the left front corner alone. The theory is that picking it up by the left front corner alone can contribute to logic board failure when the case flexes, causing the graphics chip to come loose from the logic board. If you're picking it up in your left hand (as I often do mine), pick it up in the center under the trackpad.
Good luck.
Please note: As a G3 iBook is quite old at this point, if you are faced with paying a repair bill on it, it may be wiser to put that money toward a new (or used) MacBook. They are quite a spectacular upgrade from the iBook G3. Again, good luck with whatever you decide to do.

I have virgin mobile iphone that i found,the power button doesn't work and the phone is now saying disalbed what can i do to fix it

I have a virgin moble iphone that i found, the power button doesn't work and the phone is saying disabled,what can i do to fix it?

Probably nothing, the phone has a high likelihood of being stolen and if you try to Restore it you will run into Activation Lock. Turn it in to the local authorities.

Power Button doesn't work and cannot Log Out.

Hi,
Strange thing: my power button does not work and I cannot even log out or restart or shut it down from the menu! Everytime I need to restart, I have to either force it or hold the button for five minutes, but nothing else works!
Your help is much appreciated.
Have a great time!
Best regards,

Hi, bruno7.
1. Have you tried "Mac OS: Apple Pro Keyboard Shortcuts for Shut Down and Restart"?
2. What changes did you make to your Mac before this problem arose?
3. Are you using FruitMenu? If so, check for updates, disable it, or uninstall it.
4. After you next shut down, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
5. An errant Startup or Login Item maybe the cause. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem.
6. If none of the above, when you attempt to select Shut Down or Restart from the Apple menu and nothing happens, immediately check the ends of these Console logs for clues.
Good luck!

Iphone 4 power button is stuck down and iphone won't turn on

My iPhone 4 power button is stuck down, and it won't come back up. The next best part is, my phone is either off or dead i don't know which, and i plug it into my computer/wall charger and nothing happens.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: Back up and restore your iOS device with iCloud or iTunes
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
