HP Palion dv7 Notebook PC will not power up when power button is pressed.

My HP Pavilion dv7 Notebook PC will not  power on when the power button is pressed. I have removed the battery, unplugged the AC adapter and pressed the power button for 15+ seconds then plugged in the AC adapter and pressed the power button for 15+ seconds. Then I release the power button and then press the power button again and the Notebook will power up and operate normally. I can reinstall the battery once it has powered up. What is causing this problem and how do I remedy the problem?

Hello Griff83147,
Unfortunately there could be a number of different things that caused that issue from drivers, software, possibly hardware. I am glad you got it up and running but there isn’t a clear picture of what actually caused. If a technician got the chance to work on it then they could at least narrow it down.
Sorry I could not answer your question, but this is one of those questions that can have multiple answers.
If you have any further questions don’t hesitate to ask.
Thanks

    Make sure your headphones are plugged in all the way, meaning you cannot see any of the silver still showing from the headphone's plug. 
    A feature of the Nano is to put it to sleep when the display goes out and it does not detect any headphones.

  • Notebook frequently is found turned off and will not restart even when power button is held in

    I have a dv7-3060us notebook running Windows 7,  Some mornings (every few days or weeks), I find it, powered off and unresponsive.  Pressing in and holding the power button for 5-10 seconds has no effect.  I have to unplug it and remove the battery to get it to restart.  This has happened numerous times.  I have tried it running with the battery removed and it even fails then.
    Can a software problem cause this?  I thought that holding in the power button causes a hardware interrupt and the BIOS takes over.
    Is there a known hardware problem which can cause this?
    Thanks,
    Adam

    Hey Adam,
    First off, Happy Friday! I would go ahead a try a hard reset to resolve this issue. You can find the instructions on how to do this on this page: Use Hard Reset to Resolve Hardware and Software Issues 
    If this does not resolve the issue post back with any new details and we can go from there. 
    Thanks,

  • I have a Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power off button. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Any ideas?

    I have a Power Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power on/off button again. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Sometimes my Mac goes on just by pressing the power on button but most times I have to pull the power cord and put it back in. Any ideas or help out there for this? Could it be a failing power supply? Apple Care says that this model is obsolete so there is no help from there. John

    Hi John,
    That's often a sign of a bsad Capacitor in the Power Supply, but...
    Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

    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.

  • Mac Book Pro will not start on Battery Power

    Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.

    What is the exact model of your MBP?  The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
    If the SMC reset does not solve the situation, post this from your MBP:
    Make certain that the power adapter is connected.
    Ciao.

  • My MacBook Pro will not powerup (even when connected to power supply).

    My MacBook Pro will not powerup (even when connected to power supply). The caps lock key is the only light on.

    Hi PatB11902,
    Thank you for visiting Apple Support Communities.
    If your MacBook Pro does not seem to power on, but the caps lock key will light up when you press the caps lock key, you are likely seeing a video issue.
    There are several steps that can help troubleshoot this behavior, found at this link:
    Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
    Start with these steps:
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    Start up in Safe Mode.
    If your Mac does not start up normally after these steps, here are some additional tips that can help:
    Troubleshooting: My computer won't turn on - Apple Support
    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.
    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.
    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).
    Sincerely,
    Jeremy

  • My iPod shuffle, which I prchased in 2009 only worked for a short time so I put it back in the box and just recently took it out. I will not charge and the power light does not come on. It was faulty from the start and thought I was out the money I paid.

    My iPod shuffle only worked for a short time. It will not charge  and the power light does not come on. Bought it in 2009. Put it back in the box and in my desk. Recently tried to get it to work again but no luck. Anyone else have this problem? Very disappointed with the product although my wifes work perfectly.

    Can't say I haven't done the same kind of thing...keep finding things I had every intention of...
    If you have the chance stop by an Apple Retail store and talk to them about it...they often work deals for replacement of out of warranty non-working items for prices around half price.  Won't hurt to stop by and see what they will do for you.

  • HP Pavilion dv9920us will not bootup/shutdown when on battery power

    When using the 2.6.27 kernel, my HP Pavilion will not boot up when using the battery power..... it won't shutdown either, it will just freeze mid-process unti I plug the AC adapter back in. During the boot up using the battery power, it freezes at the ACPI part.
    This has happened on the 2.6.27-2-ARCH kernel, and all other versions of the 2.6.27 that I've built. (all rc versions from rc1 - rc7).
    I wish I knew a way to fix this, I have a backup 2.6.26 kerenl on my GRUB list just in case there are no AC adapter outlets.... but it would be nice to fix this.

    I have the NVIDIA GeForce 7150M / nForce 630M with AMD Turion 64 x2 TL-60 with 4GB RAM.... so it's pretty different than the dv9000.
    My AC adapter is different too.

  • TS3798 I have a new Ipad, it says I am connected to the internet but will not load . When attempting to go to a web sight, the green bar goes 1/2 inch then nothing

    I have a new ipad, it says I am connected to the internet but will not work. When I attempt to go to a web sight the green bar moves 1/2 inch and nothing.
    I have a used linksys router that I got from work. I tried connecting with a older ipad and every thing works correctly. any ideas?

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

  • My ipad will not turn on when I plug it up, the screen light will occasionally blink

    my ipad will not turn on when I plug it up, the screen light will occasionally blink, thank you

    First, make sure that it's fully charged.
    Then, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.

    I downloaded an app in the itunes app store on my pc and it's in my library, but it will not show up when i click ipod then apps?

    You need to sync the app to the iPod

    Is the app compatible with your model iPod and iOS?
    Are any Restrictions set that would prevent installing the app on your iPod? Settings>General>Restrictions

    Does any media now sync to the iPod?
    Have you successfully synced aps to this iPod from this iTunes library before?

  • My mac will not show images when on the internet?

    My mac will not show images when on the internet?  I think I have inadvertently changed some settings but nor sure which one.

    I am going to assume you are using Safari here. If so then go to the Apple menu bar and hit Safari-> Preferences.  Under the Apperance tab there is a check box that is called "Display images when the page opens".  Check if that is unticked.
