You have to remove all cables before connecting to your computer with micro usb. Power is only connected when using a 3rd gen device and done after the initial connection.

If you have iOS 7 installed, you can try to restore it via the instructions given by lllaass in https://discussions.apple.com/thread/5634135
As an alternative, you could take it to an Apple store genius bar and have the techs test it and see what is wrong beyond the failed power button.

27" thunderbolt monitor is not powering back on with Laptop

Since updating to the new version of Yosemite my 27" thunderbolt monitor is not powering back on when plugged into my laptop via the thunderbolt port. Suggestions on how to get it back up?

Apple Support had me reset the SMC and after doing so my monitor came back up and functioned like it was supposed to. Support said sometimes after updates we need to reset the SMC if changes aren’t cleared from the previous update resulting in behaviors like I was experiencing. Below are the steps i followed to reset the SMC.....
1. Shut down the computer. 
2 Plug in the MagSafe or USB-C power adapter to a power source and to your computer. 
3 On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. 
4 Release all the keys and the power button at the same time. 
5 Press the power button to turn on the computer. 
On MagSafe power adapters, the LED might change states or temporarily turn off when you reset the SMC.

Iphone 3G won't boot past apple logo - not typical case that I've searched and read about

I am attempting to fix an Iphone 3G for a friend. Before the phone stopped working, they said the battery life was getting worse progressively until the point that they had to turn down the brightness and have it plugged in often. The phone was jailbroken and unlocked for use on Tmobile. I don't know what firmware it's on nor how it was jailbroken, just that they said it worked fine for 3 years. When this problem first occurred, my friend was able to get the phone into recover mode, but it would shut down after several seconds even when plugged into a computer or power source.
Currently, the phone will not boot past the apple logo. It powers up, goes to the apple logo, and powers down 20 or so seconds later. The spinning gear never appears. I can not get the phone to boot into recovery nor DFU mode. The computer doesn't recognize it or even acknowledge when it is plugged in, so irecover that some people use to solve their recovery loop mode i won't work either. I have the luxury of having a functional iphone 3g that I used to swap parts to narrow down the culprit.
Steps taken:
replaced battery
swapped usb connector on bottom of phone
swapped lcd assembly in case it was the home button
took the motherboard out and placed it in the working phone, and it still doesn't boot past the apple logo
I'm out of ideas at this point. Thanks for anything you guys (and gals) can think of.

I See a lot of those on my bench. The cause is the charge IC is burned out usually by a non Apple cable. The only way to get it to fully boot is to put a fresh charged battery in. Once a new fully charged battery is in it will continue to work fine including charging. But if you ever power off the device or it turns off due to dead battery it will not boot up on its own And you will need to swap batteries again.

Hey Angelo_here,
I'd run through these steps:
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Reset the SMC.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

USB not powering external drive on new macbook pro

My new macbook pro retina display is not powering an external 750GB GDrive moblie. Is anyone having this problem?

It seems as if a number of people are having problems with the USB 3.0 ports on the 2012 MBP's - particularly when it comes to external storage devices.
As you don't have a FW800 port (or, yet, an adapter) the best thing you can do is either return it to your local Apple Store and see if they know of a 'fix' (which I doubt - someone would have posted that by now), whether it's only occurring with some MBP models, and you can always file a bug report with Apple: https://bugreport.apple.com/cgi-bin/WebObjects/RadarWeb.woa/wa/signIn - you must sign in with your Apple ID.
Hate to be the bearer of bad news, but there have been quite a few people posting here with the same problem.
Good luck,
Clinton

When did it happen? After updating/upgrading? or just randomly?
You can try to perform a SMC reset and resetting the PRAM:

What can I do if iPhone 5 is not powering after after I put it charge?

What can I do if iPhone 5 is not powering after after I put it charge?

Hmmmm are you saying tht it will not turn on even after being charged?
Take a look at this article named iPhone: Hardware troubleshooting http://support.apple.com/kb/TS2802
Battery does not charge from the USB power adapter
Important: Only original iPhone can be charged from a FireWire-based power source. If iPhone is connected to a computer that's turned off or is in sleep or standby mode, the battery may drain.
Verify that the outlet being used is working.
Try another USB power adapter if available.
If no other USB power adapter is available, try connecting to a high-power USB 2.0 port (not a keyboard). The computer must be turned on and not in sleep or standby mode.
Try another USB cable if available.
Also refer to iPhone and iPod touch: Charging the battery.

Apple tv not recognising computer

I want to see my holiday photos on my tv by via the apple tv box. I have switched on home sharing and on the tv the photos show in photo streaming but my computer is not being recognised by the apple tv.

2 things that can cause a long download time
1. your internet connection is not fast enough
2. apples server is not powerful enough to service all clients at one time
think to get quick download you need a 10Mbit/sec connection or faster

IPhone 3GS not powering up || Usual remedies not working

My iPhone 3GS is not powering up.
I had it connected to the wall charger and direclty with the computer for a few days and still it won't start.
I tried pressing the power and home buttons together a number of times but it would not start.
The phone is not being detected in iTunes.
I have tried with the original charger as well as my iPad 3 charger and its not working.
Its not a problem with the cable as the iPad and iPhone 5C are charging on the same cables.
Any ideas will be highly appreciated.
The phone was recently unlocked by AT&T after completing the 2 years contract. The same was confimed by the AT&T Store associate.

If it won't turn on, even after being plugged into a wall outlet for several hours, you most likely have a hardware failure. If under warranty, make an appointment at an Apple store. If out of warranty, Apple has an out of warranty replacement program, the cost is US $199.

Tx1000 not powering up !!!

HP Tx1000 totally failed....not powering up at all anymore....Seems like the settlement between HP and NVidia only applies to US residents.......is there anything Canadian customers can do?

Unfortunately that hasn't worked. I bought a new battery just in case (which is why it's taken so long to reply). I'm scared of pressing the PMU button again. I guess I'll have to see if Apple can figure out what's wrong.
Thanks for the replay Tom.
