Touch Smart IQ500 will not power on at all

HI
I have owned my pc since 2008. Yesterday my kids disconnected it and and connected it to a power cord. Well it turned on once then turned off. Ever since it will not power on at all. Does that mean my whole computer burned up or do you think i just need a new power supply. Please Help..Thank you!!

My ipod touch generation 5 will not power on though it was showing to b e fully charged. I have been pressing and holding the on button on the top which usually cause a the screen to light up. Is there some way to get it to work?

Try:

- Also try DFU mode after try recovery mode

- 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 another cable
- 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.

L655 has solid white power LED and soid orange battery LED and will not power on at all.

L655 has solid white power LED and soid orange battery LED and will not power on at all. I tried a second power adaper. Any other suggestions? It does not even try to power on. No fan or any other noises.

if it is not powering up on battery or AC, then there is either something wrong on the motherboard keeping it from powering up, or a bad power switch. I personally have not encountered a bad power switch on any of my Toshibas, so I would suspect something with the motherboard. It is strange that it does indicate that your plugged in and charging. If you leave the power adapter plugged in, does the battery status eventually go white?

MacBook will not power on at all

Hi there,
My 2011 13" MacBook Air will not power up. It is charging, and recently turned from amber to green.
I have tried to reset the SMC and PRAM - obviously these options didn't fix the problem.
I cannot hear any fans or anything moving in the MacBook that would indicate that it is powering on.
Any help would be greatly appreciated.

HT4623 iPad Mini - one year old. Plugged it in to charge and now it will not power on at all. I have tried different cables to ensure it was not a faulty cable. What else can I do?

I have an iPad mini that is exactly one year old. I plugged it in to charge it. The next morning it ws completely dead. I can't get it to come on no matter what I try. I have tried a different cable to see if my cable was faulty, but that id not resolve the issue. No matter what I try, I can not get it to power on. I cannot get iTunes, nor my computer to recognize it when it is plugged in.
Has anyone else had this issue? What can I do? Any help would be appreciated!

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

System will not power up at all AC power light only G50-109NR

Hell,
I have a HP G50-109NR that has had the following parts replaced up to this point.:
System Board
Power On Assembly Board
Plug In Type DC Power Jack
I get the light next to the power jack to come on when I plug the power supply in.
That is all I can get to happen on this laptop. I don't want to give up, it seams to me like it is still not getting power but yet the little light next to the plug lights up. I have checked the output of the power supply and it seems to be working. I mean not a beep no other lights come on nothing. This time the system board came directly from HP. I have used very good anti static protection through the process. Anti static mats my self and even my hand tools are grounded together.
Please anyone that has any Ideas at all please contact me via my email [text removed for privacy]
Thank You for any help received.

Have you tested the polarity, voltage, amperage and such coming out of the power brick? There is definately power coming out of it, but LEDs, as I'm sure you know, will light up with a lot of power specs, including what may be out of range for the motherboard to power on with.
I take it the battery is completely discharged? I have owned several second hand laptops that have had issues with batteries. One, the battery was toasted, and if it was in the laptop, it wouldn't power up regardless of the DC input. The one I'm using now won't power on unless the battery /is/ installed, though the lights come on. Maybe you have a similar situation there.
I'd still consider stripping everything non-essential off the motherboard to try.

HT201412 My IPod Touch (4th generation) will not turn on at all. It has been charging all day and will only function if its plugged in but when its unplugged all you see is a blank black screen. Any ways to solve this?

Lenovo laptop will not power up at all. Please help

Ok, so I got up this morning to turn my laptop on and it acted like it was gonna power up but nothing ever appeared on the screen. So I took out the battery and put it back in to see if that would work, but now it doesn't show any signs of power at all. I read somewhere it could be the motherboard cause even while plugged in it doesn't work. I just got the laptop a week before Christmas so it's not like its that old. Also the battery was holding a great charge before this happened so I know its not dead. I can find the receipt to bring it in, but I do have the bank statement from where I paid with a debit card so would that suffice enought to exchange it? Thanks for any help.

Kinda sounded like they tried that nono "cause even while plugged in it doesn't work."
Definitely try xl's info and try taking out the battery and unplugging it, hold down power button for 15ish seconds, then reinsert battery, replug in and try to power it on.
