My unit will not start. It is getting power. What could be wrong?

I have a MAC Book and it is getting power both through the battery and the direct hook up. When I press the ON switch nothing happens. Any idea what could be wrong?. I have taken the battery out, let it ist and then replace it. No change it still will not turn on. HELP.

Have you tried resetting the System Management Controller? That is a good first step for power related issues such as this.
Best of luck.

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

Have you tried logging out of your CC desktop app, then logging back in again? Quit/Restart won't work, but logging out and back in should. See here: https://helpx.adobe.com/creative-cloud/kb/sign-in-out-creative-cloud-desktop-app.html

Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

My macbook pro will not start after pressing the power button

I have bought a macbook pro last year and now, I have a great problem since a few months.
My macbook does not boot up, I hear no fan noices and no LED lights are blinking...
Battey is full, but nothing happens (means system will not start up).
I have also tried to start with the Power button - but the similar effect "NOTHING HAPENS".
What I don't understand is, if I do nothing for one or two days and press then the power button, the system will start up and full functionality for a few days.
And anytime I get the same problem again... and must wait also for a few days.
Can anybody support me please.
Thank you all in advance and looking forward to a fast reply.

MacBookPro 17" mid 2010 will not start, green light on power plug OK

I pushed the on button and the computer would not start. No sounds and no lights. My power cord showed the green light so I unplugged it and plugged it back in and tried to start the computer up again, did this several times. Finally the green light changed to orange/red and when I pused the on button it came on. When I shut it down it has 99% power showing. Next morning when I pushed the power button the same thing happened except I still can not get it started. 2 days later. I spoke with an Authorized Apple Service Provider this morning who walked me through taking the back off, unplugging the battery waiting 20 plus seconds plugging it back in, putting the back on and trying to start it. It did not start up? Before I have to ship this off can anyone help me with what I am dealing with?

Hello MacBookProUserette,
I would be concerned too if my MacBook Pro would not power on. I recommend following the steps in this article when experiencing an issue like this. I recommend reviewing the full article, but I think steps 2 and 5 are particularly useful in the situation you described:

My iPad will not connect to my wifi. What could be the problem?

I have an iPad (1st Generation). It will not connect to my wi-fi. How can I resolve this issue?

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.

Hard drive and dvd are not recognized in the setup menu, what could be wrong?

The hard drive and dvd drive are not recognized on the setup menu for my Pavilion a4316f desktop computer. Could it be a failure of the controller? Can a PCI controller be used to replace the mother board controller?
This question was solved.
View Solution.

The Recovery process would erase you hard drive, and attempt to install a fresh OS. Decidely a bad choice if you wanted to save your data files. The Recovery sets are "tattoo" with the BIOS hardwafre configuration. It will not, IMHO, recognize the PCI Sata card.
You mentioned the Recovery program on the hard drive actually requested the installer of the controller (PCI card). Try running from that.

Itunes will not start and keep getting send error report to MS message

I had a system crash and have re-built the sytem with XP Professional SP2 with all upto date patches. Symantec Norton Internet Security 2007.
Downloaded the latest Itunes and Quicktime update on Monday evening and now every time I click on the Itunes icon, i get unable to start application and do you want to send an error report to Microsoft.
I remember all the problems with the 6 to 7 upgrade and am hoping this is not a repeat.
Any help appreciated.
