D20 turns on when plugged into mains

hello, I have bought a used lenovo d20 workstation, when plugged into the mains it automaticly starts up (without pushing the power button) and shuts down after 20-30 seconds, is that a power supply fault ?Anyone else experienced this ?  thanks 

That is the normal for this unit.  If you look at the back of the power supply you will see a LED right under the power plug input.  If that light is green the the system is letting you know that the Power Supply is operating as it should.  If it is red then you have a faulty power supply.  The system does that short power cycle to test the powersupply.  Thats all it isMike

  • IPod classic won't turn off when plugged into a home theater dock; what's up? will it hurt to leave it on all the time?

    I bought a new iPod Classic and it won't turn off when plugged into a home theater dock. Is this normal and will it hurt the iPod if i leave it on all the time?

    Hi there,
    How old is your Classic? Often, after a couple of years, rechargable batteries begin to fail, especially after such a long period of inactivity. This happens with any gadget with this type of battery.
    Try leaving it plugged in for 24 hours, and try again, to rule out that it isn't just really low on charge. If this doesn't help, it may be a good time to buy a replacement. New iPod Nanos and Touches will be released this October.
    Below, I've linked to an Apple website which explains rechargable batteries, and why yours may not be working.

    I hope this helps, and I hope upgrading your device will not feel like an unnecessary expense. Let me know if you have any more questions,

  • IPhone only turns on when plugged into wall

    Hello, I have an iPhone 4 CDMA and it only works when in is plugged into the wall.  It does not work properly anyother time.  When I plug it into the computer it goes through the Boot Loop.  When I put it into DFU mode and recovery mode and try to restore it in iTunes it doesn't restore and just gives me a bunch of different error codes.  The most common error codes are 2001, 2006, or 1604.  It use to give me Error 21 but I fixed that by editing the hosts files.  I have tried six different computers and seven different iPhone cables on the computers and I still get the same error codes every time.  It does not work if it is not plugged in.  I have replaced the dock connector/charging port and the battery.  I bought it used and think it may have been jailbroken at on time.  It has not been jailbroken in the time I have had it.  I have also tried Tinyumbrella and that did not work.  What could be wrong with it? 

    Hello! When it turns off, do you notice if it drains quickly or does it just shut off even with full battery? Because this can also be caused by battery problems. Your iPhone may not be turning on even when plugged into a computer because a wall outlet charger gives off more power than a computer does.
    I suggest you bring your phone to an Apple store right away. They could at least help you determine the problem, and by then, you can decide what to do with your iPhone - you can have it repaired (if they say it's still fixable), you can have it replaced with a refurbished iPhone, or you can buy a new phone completely.

  • My iPhone will not charge and will only turn on when plugged into adapter.

    I have tried to reset and nothing. It turns off if I unplug it and will only turn on when plugged in. The charge has not moved above 19% even though I let it charge for 3 hours while I was out. What do I do?

  • My ipod nano 6th gen will only turn on when plugged into a power source.

    My ipod nano 6th gen ONLY turns on when it is plugged into a power source. As soon as I unplug it, it turns off. I also tried to reset it and it did not help. Any suggestions? 

    Howdy mela1223,
    If I understand correctly your iPod will not stay on unless you have the charger plugged in even after resetting it. Normally this would indicate a hardware issue that would need a repair but to cover all the bases before that, the last troubleshooting that can be done for it would be to restore it with iTunes on a computer. 
    Restoring iPod to factory settings - Apple Support
    How to restore iPod
    Verify that you have an active Internet connection, because you may need to download new versions of the iTunes and iPod Software.
    Download and install the latest version of iTunes if necessary.
    Open iTunes. Connect your iPod to your computer using the USB or FireWire cable that came with your iPod.
    After a few moments, your iPod will appear in the Source panel in iTunes.
    Select your iPod in the Source panel. You will see information about your iPod appear in the Summary tab of the main iTunes window.
    Click Restore.
    If you are using a Mac, you will be asked to enter an administrator’s name and password.
    A progress bar will appear on the computer screen, indicating that stage one of the restore process has begun. When this stage is done, iTunes will present one of two messages with instructions specific to the iPod model you are restoring.
    Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).
    Leave iPod connected to computer to complete restore (typically applies newer iPod models).
    During stage two of the restore process, the iPod displays an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remain connected to the computer or iPod power adapter during this stage. 
    Note: The progress bar may be difficult to see, because the backlight on the iPod display may be off.
    After stage two of the restore process is complete, the iTunes Setup Assistant window will appear. It will ask you to name your iPod and choose your syncing preferences, as it did when you connected your iPod for the first time.
    Thank you for using Apple Support Communities.
    Take care,
    Sterling

  • How do I restore my iPod Touch that only turns on when plugged into the wall?

    I found my old iPod Touch 4th generation in my backpack, and my backpack went through the wash, (It shouldn't of been too bad since it was in the side pocket) but it goes dead instantly as soon as I take it out of the wall charger, and it does not turn on when I plug it into my computer. It also has a pass, (That I forget) so I need to restore it. Is it possible to restore it without connecting it to a computer?

    No. You have to connect the iPod to a computer with iTunes to restore the iPod.
    Did you throughly dry the iPod before you started try to use it?

  • IPod very low on battery and now won't turn on when plugged into PC

    I haven't used my iPod for a few weeks, so now the battery is obviously completely empty. The problem is that it won't turn on when I plug it into my PC to charge, even after half an hour or longer. Is there something I can do, or do I need to get a completely new battery put in?

    If you are unable to give specifics about the problem or what you need to do, it's going to be rather hard to give you recommendations or alternate suggestions.
    As I said, if I recall correctly, the iPod will stay on if it's being charged. But, in case I'm misremembering, are you holding down the button until you see the red arrow that says "Slide to power off"? Have you tried restoring it?

  • I replaced battery and now will only turn on when plugged into a charger..

    I replaced my batter on my iphone 3gs and then it will only turn on when i connect it to a power source.
    After it has turned on you can take it off charge and it will stay on...
    Help please!! thanks

    Either you got a bad battery, didn't install it correctly, did some other damage while installing, or haven't let it charge enough yet. There's really nothing we can do to help you with any of those scenarios.
    Regards.

  • IPhone says 'Connect To iTunes'  but won't turn on when plugged into the computer.

    Hi all.
    Having a major problem with my iPhone today. This morning it slipped off my desk somehow and fell on the floor. When I picked it up it would not turn on or respond, so I plugged it into the charger, the apple logo appeared and then the lock screen came up - it said slide to unlock, so I did and then it just said 'connect to iTunes' and I could not use it at all. So I unplugged it from the charger and it immediately turned off and became unresponsive again. I plugged it into the computer and started up iTunes. The apple logo appeared on the phone but then disappeared after about 15s. Then a few moments later the logo appeared again. And then disappeared again. This happens every time I plug it into the computer and what I described with the charger happens every time I plug it in there. Unfortunatley I cant seem to put it into recovery mode, especially as my home button is almost completely unresponsive and I have no idea if its working when trying to put into recovery mode. Please help!

    You could try to do a hard reset, sometimes resetting the phone helps. Hold down the sleep/wake button on the top and the home button until you see the apple logo, this make take a minute or two but this might help.

  • My ipod 5th gen wont charge or turn on when plugged into the wall or on my docking station

    I have had my iPod for around a year now and it has been perfectly fine........until now. I came home from work to find my iPod was turned off, I assumed that it had just run out of charge. I plugged it in to charge using the power adapter and nothing happens when I put it to charge on my docking station?
    Can anyone help? Or does it look like a new iPod is on the cards?
    Thanks

    Try:                                               
    - iOS: Not responding or does not turn on           
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - 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.

  • IPhone 4 won't turn on when plugged into computer nor charger

    My refurbished iPhone 4 has the latest iOS 5.1.1 update and my mom's computer has iTunes version 10.6.3.25. However, recently it has been having issues holding a charge and now as of yesterday it won't turn on period. When it does it's only for a split few seconds and then it turns off again.
    When it's connected to a wall charger it immediately turns on
    and then lock screen apprears with the message "activation required". *Note it says it has at least 75% battery*
    Upon entering my lock code my home page is only a page that says to "connect to iTunes".
    When I attempt to take the phone off the charger, it dies
    and is completely unresponsive as I connect it to a computer.
    The computer doesn't recognize it and the screen remains black.
    If I leave the phone alone on the charger it will continously go through a process of shutting itself off and turning back on. The time always restarts at around 7p or so and the date is Wednesday, December 31st. Also as it's plugged in, I manage to turn the phone off and on and reset it but the phone just keeps displaying the "activation required" screen. Can this be fixed at a Genius bar or should I have it replaced?

    Sounds like a damaged device, take it to Apple for evaluation.
    If it's under warranty, they will replace it.
    If it's not under warranty, an Out of Warranty replacement is $149US.

  • Will dead battery stop netbook g62 from booting up even when plugged into the mains

    Had the battery warning (last week) 
    did not replace now will not boot up even when plugged into the mains.  Is this likely to stop booting or just a case of more than one thing wrong at the same time. New battery expensive to buy if it is likely to be something else wrong.

    A battery can be so dead it will keep the laptop from powering on fully when the dead cells suck up too much of the power. Will it turn on with "mains" connected but battery removed?
