HPE-400Z start switch won't turn on

The power switch will not turn the PC on.
The power supply and motherboard lights are on, but not the power switch light.
I have no clue as to what the problem is, or what to look for. Has anybody had this problem, and found a fix for it? Is there anything that can be ruled out, or is there anything that has likely caused this symptom?

Even though the light on the power supply unit is on, I still suspect that it may have failed. Here is a guide to help you troubleshoot it:

MX922 hangs, power switch won't turn it off. Can I get it going without just pulling the plug?

The printer seems to do this to me about once a month. If I pull the plug and then reconnect it, that resets everything and gets the printer going again, but I get a nasty error message that I'm not supposed to do that. But what else can I do when absolutely none of the front panel buttons do anything at all? And the printer doesn't respond to any computer commands either.

Hi williamauer,
If it appears that none of the buttons are stuck on the printer and an error message is not displaying and you are unable to turn off the printer normally, the printer may require servicing; please call or email us at one of the methods on the Contact Us page for further assistance.

My phone although fully charged has just switched itself off and won't turn back on again! I'm just coming to the end of a 2 year contract and never had any problems with it. Help please!

My iPhone 4 although fully charges has just switched itself off and won't turn back on again. I've tried taking the sim card out but nothing happens. I'm just coming to the end of a 2 year contract and never had any problems with it before. Help please.

HT201401 my iPhone 5 randomly switched itself when somebody was calling me and now won't turn on. it had 90% battery, I've tried factory reset, connecting to iTunes and nothing works. the phone is approx 18 months old so surprise surprise out of warranty.

My 5S just started doing this on Thursday: every fraction of a second or so it oscillates between connecting and disconnecting with the charger (USB or wall, doesn't matter). Since it's still under the limited warrantee, I took it to the local Mac dealer (I live in a small town w/out an Apple store) and they shipped it off. I'm waiting now for the replacement--telephonless, too!
What concerns me is that many people seem to be having this issue.
You were right to be suspicious of the Apple store employees. Once they replicated the behavior that you experienced, they should have immediatly offered to exchange your phone. Anything else, in my opinion, is unacceptable. As long as your phone is still doing it, I'd go back, ask for the manager and tell them to exchange your phone.

HT4623 just updated my iPhone 4s to ios6, now my phone won't turn back on. The apple logo comes on and sits then shuts off. I have held down the home button and on/off switch several times to reset, but same problem persists.

Place iPhone on Wall Charger for at least 10 minutes. Then keep on charger and Reset, hold both home and power buttons until the iPhone begins to start, this can take about 20 seconds of holding both buttons while on charger. If still problem, open iTunes 10.7 on computer, connect iPhone to computer with USB Cable, hold both home and power buttons for about 20 seconds until iTunes recognizes iPhone in Recovery Mode, then click Restore button of iTunes. If still problem, try DFU Mode Restore, here are the steps. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power buttons, after exactly 10 seconds release the Power Button, keep holding the Home button until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time. If the iPhone screen is black, blank this is DFU Mode. Click the Restore button of iTunes. DFU Mode can be difficult to enter sometimes, just keep trying. DFU Mode is a black, blank screen with iTunes saying Recovery Mode. If still problem and there is Warranty or AppleCare make Genius reservation and take to Apple for resolution.

My wifi won't turn on at all. Even when I try switching the wifi button to on, it's just grayed out. So it's stuck on off. I need help

Turn your phone off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your phone and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a phone in recovery mode. Now you can restore to factory settings.

Macbook (2.1Ghz white 2008 model) display won't turn on during start-up

hi all,
my problem is pretty simple.
Sometimes, after having used an external display with my Macbook (using the Apple Mini DVI > DVI adaptor: http://store.apple.com/au/product/M9321G/B?mco=MTY3ODQ5OTY ) the Macbook's own display won't power on during the next boot-up. I can hear the hard-disk start up, and the system boot, and I'm even able to navigate my way into the user login and shut the computer down (all via the keyboard). So the computer is definitely powering up (and in a seemingly normal way), but the display isn't.
For example, last night I was using an external display with my Macbook. This morning I plug the display back into my Mac Pro, then power-up my Macbook. But the Macbook's display won't turn on. It's as though it thinks the external display is still plugged-in. I know, that if I re-connect the external display, the Macbook's login page is displayed, but only on the external screen.
The problem only arose after I started using this particular external display (a cheap 22" BenQ, model G2222HDL 'senseye 3'). I wouldn't normally use the display with my Macbook, but my Mac Pro has a **really** noisy optical drive (CD/DVD), which makes watching films pretty unbearable (if you're into sound anyway, which I am).... so until I get my Mac Pro's drive sorted (when I have a few spare days when I won't be needing it), I'll have to continue using my external display with my Macbook to watch films.
My Macbook's specs are as follows:
2.1Ghz Intel Core 2 Duo Macbook (2008 model - I think, maybe 2009?)
4Gb RAM
Running OS X 10.5.8
Are there any known display issues with these models of Macbook? Or are there any software/firmware updates that address any display issues?
In general, I don't update the software/firmware unless I need to, or unless something doesn't seem to be working properly.
However, I've just checked Software Update, and noticed there is an SMC firmware update (1.4). So I might give that a go and see if the problem persists.
However, the problem is intermittant, and kind of unpredicatable, so I might not know for a while if it solves the problem or not.
Has anyone else had a similar problems?
Alternatively, is there a possibility there is some kind of virus or file-corruption causing this problem?
My girlfriend has a similar model of Macbook (which she's never had any problems with). Recently I moved a whole bunch of files from my Macbook to hers, and she noticed that hers had a similar issue starting up, where the display failed to turn on.... so it seems like
a) it might be a common-ish problem in this model of Macbook
or
b) perhaps I've got some kind of virus on mine?
I've been using Macs for about 15 years (yet, I don't consider myself a computer expert, when it comes to the technical details). In those 15 years, viruses have never really been a concern to me, as I've never really thought they were much threat to Macs. However, I guess, as Macs get increasingly more popular, there's a possibility people will write more Mac-specific viruses...?
Anyway, I'm open to suggestions : )
Regards,
Sam
PS I've tried:
-re-starting the computer multiple times (which sometimes works, but usually doesn't).
-re-setting the SMC (which usually works, but not always)
-plugging/un-plugging the external display to try and jog the computer into noticing it isn't connected (which doesn't work)

let me ellaborate on this part:
"b) perhaps I've got some kind of virus on mine?"
I mean, " perhaps I've got some kind of virus on mine, and I've passed it on to hers?"

Just bought a new iphone4 and was loading os6 and now it won't turn on. the apple glows like it is starting up, then the screen goes black and then repeats the same process over and over. i have tried to reboot multiple times now

I am assuming the phone was working prior to you installing IOS 6? Did you use itunes to install IOS 6 or just run from the phone?
When I tried to do the Over The Air update to IOS6 on my iPhone 4, it errored out and I had to connect it to iTunes and select "Restore" from the summary screen after iTunes finds the phone is connected. If this works for you, it will go through a couple of reboots that take a few minutes to complete. It should then give you the option to start with a fresh new phone or to use one of your previous backups to load your contacts and other information, provided you have backed up the phone previously.
I hope this helps you my friend!

Why does my iMac just quit and it won't turn back on. Sometimes I can start it a few days later.

It was working just fine and then it just quit. I tried turning it back on but it wouldn't work. Then like 3 days later, I tried turning it on and it came on and worked ok and just quit again. Again, I tried turning it back on and again, it wouldn't come on. I tried again a few days later and it came on. What the heck is wrong with this computer?   It has Mac OS X 10.6.8 and the following is the info I got from profiler:

It had a program called deep freeze on it when I first obtained it. That program would not allow me to make any changes or save anything. A friend gave me a disk and I installed it and it took that program away. It was working fine and then as I said, just quit. I got the computer from an auction from a community college and deep freeze was the program they used to make sure the students using the computers couldn't change anything. When ever the computer got turned off, it would default back to factory settings. When it first turned off and wouldn't start again, I tried taking out one of the two memory sticks and it worked. I then went and bought two new memory sticks and installed them and it worked ok. Then it started doing the same thing again.

Hi codyfromchurchill falls,
Welcome to the Support Communities! The resource below will provide some troubleshooting steps if your iPhone is unresponsive or won't turn on.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
http://support.apple.com/en-us/HT201412
If you see a black screen
You might need to charge your device before it can turn on. Plug in your device and let it charge for at least 10 minutes (20 minutes for iPad), then try turning it on.
You should see a battery icon while your device is charging. If you continue to see a black screen, reset your device. If your device doesn't respond when you press buttons
Your device might not return to the Home screen when you press the Home button, wake from sleep when you press the Sleep/Wake button, slide to unlock or power off, or it might appear frozen. Try these steps:
Restart your device.
If it still doesn't respond, or if it doesn't turn back on, reset your device.
If your device gets stuck during startup
When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
Make sure that you have iTunes 12 or later on your computer.
Put your device in recovery mode.
When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.

I dropped my iphone (not from a great height) and now it won't turn on however when I plug it in the white apple shows on my screen. My lock button has been broken for awhile so I can't even try switch it on!

What can I do? I dropped my iphone (not from a great height) and now it won't turn on however when I plug it in the white apple shows on my screen. My lock button has been broken for awhile so I can't even try switch it on!

Once you have a proven, working Charger... Charge the Device for a couple of hours. Then try to turn it on.
If no joy...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
If the issue persists...
Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step...
Be sure to make an appointment first...

I dropped my iPhone 4 in water and now it won't turn on at all, will i lose all of my data, for example my photos and messages etc? and is there any way you can back the phone up without having it switched on?

If you had previously been backing up to iCloud (or a computer with iTunes), you would possibly have a backup. That said, if you can't turn the phone on, you cannot create a backup of the device now. Sorry.

Have you tried forcing a reboot? Hold down the sleep and home keys for about 20 seconds. If you see a silver apple it's rebooting.
