Pro Book 450 G1 will not turn back on

Hi all,
My HP Pro Book 450 G1 will not turn back on, and a orange light blinks 8 times next to the AC adapter whenever I press the power button. I couldn't do anything. Any other suggests regarding how to fix this problem?
Thank you.

  • My MacBook Pro just shut down without notice. It had about 40% of the battery life. It will not turn back on and I noticed when plugged in the little light on the power cord is blinking orange, not a solid green like normal.  Anyone have this issue before

    MacBook Pro just shut down without notice. It had about 40% of the battery life. It will not turn back on and I noticed when plugged in the little light on the power cord is blinking orange, not a solid green like normal.  Anyone have this issue before?  I've only had this for about 3mos.  I called apple support. They tried one thing then said I have to take to the apple store. Unfortunately I don't have one nearby. So before I travel an hour+ away I thought is give it a shot on here. Thank.

    Hi S,
    Did they have you try an SMC Reset: http://support.apple.com/kb/HT3964?

  • Wi-Fi turns itself off and will not turn back on

    Right, I had to create a new Apple ID just to access the forum, because for some reason the ID I've had since they existed just throws up a "Page Not Found" error when I log in (backsoon/error URL).  That was just the most sour and rotten cherry on this cake...
    So, I have a Mid-2012 MacBook Pro, updated to 10.9.5.  For a very long time my bluetooth has been unavailable.  The menubar icon is grey and has the broken bolt through it, the presence pane is missing, and under System Information it finds no hardware.  This was annoying but not particularly problematic, as I rarely if ever use bluetooth.  I only mention this because I know the BT & Wi-Fi board is the same item.
    Of late, however, something much more troubling has started occurring.  My Wi-Fi has been giving me the most obnoxious problem I have ever had with a computer.  At a seemingly random interval that has rapidly shortened to at most 30 minutes, sometimes as low as a single minute, the Wi-Fi will turn off without me knowing.  What I mean is, while the menubar icon will still show full strength, all internet apps lose connection.  If I click the icon, the pulldown menu is devoid of all networks (including the one it is supposedly connected to), and does not find any networks after searching.  If I turn the Wi-Fi off (as though to cycle it off-on), it will not turn back on.  If instead of looking at the menubar pulldown, I go into System Preferences, Wi-Fi is listed as "Off" already and it likewise cannot be turned on.
    System Information does still show the actual hardware card as existing, unlike the BT card.
    The only two changes since this started occurring (though the BT was gone then as well) were switching from a B/G router to an N router, and the October 25th 2014-005 Security Update.  And yes, all our other devices (windows laptop, Yosemite MBP Retina, iPad 1, iPhone 4, 5 & 5S, HP Photosmart which I cannot print to with no wifi) all connect to the Wi-Fi fine.
    So far, I have tried:
    • Removing all the network-associated .plist files.
    • Resetting the PRAM & SMC.
    • Creating a new location in System Prefs with only Wi-Fi in it.
    • Making Wi-Fi inactive and re-activating it in System Prefs.
    • Verified/Repaired Permissions
    • I believe I have verified the drive, but I will try again.
    I have not yet tried reinstalling the system, or a clean install.  The reason for this is the same reason I cannot bring the computer to a genius bar (yes, AppleCare is still active).  I cannot be without this computer, I am an engineering student with finals less than a three weeks away, I have projects and homeworks due even across the coming Thanksgiving break.  Luckily it waited until this weekend to become truly infuriating, so I may have a chance to try a reinstall and/or clean install.
    Any suggestions further would be greatly appreciated.  I'm not one to buy into conspiracy theories, but...  This basically started happening a week after Yosemite came out (which I cannot yet upgrade to because its Java version breaks MatLab, and the workaround is too kludgy for me to use).

    This is just like my problem on my 2011 MacBookPro. It drops the wifi connection repeatedly. Sometimes it will reconnect immediately when prompted , sometimes it takes 10 or 20 attempts to login with the router password, continually reporting "incorrect password' until it suddenly connects with that same password!  Sometimes it will then drop that connection within half a minute , sometimes longer. I kept thinking it was a BT internet problem but my iMac, iPad and iPhone all remain connected to the same wifi with no problems. The iMac is also running Yosemite 10.10.1 .  I understand this is a known problem. When will Apple release a fix??

  • IPod will not turn BACK ON!  Cold weather?

    My iPod will not turn back on. I left it in a cold car for a few days while I was at my family's house, and the battery must have died while I was there. I came home and plugged it in, but it wouldn't charge or turn on. Help!!

    Try sending it to the itunes store because when i left my ipod in a car for a few days it worked fine. if you haven't tried the 5 rs try those first.
    To reset your iPod nano (2nd generation):
    Reset
    1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
    2. Press and hold the Menu and Select buttons until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.
    Tip: If you are having difficulty resetting your iPod, set it on a flat surface. Make sure the finger pressing the Select button is not touching any part of the click wheel. Also make sure that you are pressing the Menu button toward the outside of the click wheel, and not near the center.
    If the above steps did not work, try connecting iPod to a power adapter and plug the power adapter into an electrical outlet, or connect iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep.
    Retry
    Retry your iPod with a different USB or FireWire port on your computer (please note that the latest iPods can only be synced through USB).
    Restart
    Restart your computer, and make sure that you have the latest software updates installed.
    Reinstall
    To reinstall your iPod nano (2nd generation):
    To update and reinstall your iPod software, first download the latest iTunes software.
    Next, open the new version of iTunes and connect your iPod to your computer. iTunes will then automatically check to see if your iPod needs to be updated and perform the update for you.
    To then check the software version on your iPod, select it from the source list in iTunes. iTunes will display the information about your iPod.
    Restore
    To restore your iPod nano (2nd generation):
    Warning: Because Restore erases all of the songs and files on iPod, make sure to back up any files you've saved on the iPod disk. All of your songs, videos, podcasts, audiobooks, and games can be loaded back to your iPod provided that you have them stored in your iTunes Library. If you use the Nike + iPod Sport Kit, see this document for more information.
    How to restore your iPod:
    Make sure you've reinstalled the latest version of iTunes.
    Open iTunes, and then connect your iPod to your computer.
    After a few moments, it will appear in the Source list in iTunes.
    Select your iPod in the Source list and you will see information about it appear in the Settings tab of the main iTunes windows.
    Click the Restore button. You will be prompted with one or more restore options that may prompt iTunes to automatically download of the latest iPod Software. The 4 possible restore options are:
    Restore Option 1: Restore - Restores with same iPod Software version already on iPod.
    Restore Option 2: Use Same Version - Restores with same iPod Software version already on iPod even though a newer version is available.
    Restore Option 3: Use Newest Version - Restores with the latest iPod Software on your computer.
    Restore Option 4: Restore and Update - Restores with the latest iPod Software on your computer.
    A progress bar will appear on the computer screen indicating that the first stage of the restore process has started. When this stage is completed, iTunes will instruct you to leave iPod connected to your computer to complete restore.
    During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage. Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.
    After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.

  • My iPod shut off randomly and will no longer turn back on. I plugged it in to charge it, but after several hours it will not turn back on. What should I do?

    My iPod turn off randomly. I plugged it in to the charger, and after several hours, it still will not turn on. I even plugged it into my computer and pulled up iTunes, where it showed up on the screen as plugged in, but still it will not turn back on. Any suggestions on what I should do?

    - First try resetting the iPOd:
    Press and hold the On/Off Sleep/Wake button and the Home
    button at the same time for at least ten seconds, until the Apple logo appears
    - Next try restoring the iPod via iTunes, first from backup and if still problem to factory defaults/new iPod.

    Try:                           
    - iOS: Not responding or does not turn on
    - 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.

    My 160GB ipod classic stopped whilst playing music and will not turn back on despite having almost a full battery. I have tried connecting to itunes and a docking station but will not turn on at all - HELP?!
    I've had this from new for 2 years, the battery life is excellent and lasts for days so I know it's not a power issue as it was fully charged that morning. No signs of connection in itunes, it's not showing as a connected device.
    Can anyone please help?

  • I turned the Ipad off after a game and now will not turn back on. Any clues?

    I just finished playing a game on my new Ipad, turned it off and now it will not turn back on! The battery was charged. Nothing comes on the screen when I plug it in to the charger either. Any clues?

    Be sure to try charging it off the wall plug, not a USB cable to your computer - USB connections generally do not supply enough power for an iPad.

  • The iPhone I got yesterday turned off and will not turn back on.

    The iPhone I got yesterday turned off and will not turn back on.

    Is it charged? If so try a reset by pressing and holding the sleep/wake button and the home button for 20 seconds (maybe longer) until the Apple logo appears, ignore the red slider.  Then turn back on. You won't lose any data doing the reset.  If it's not charged, charge it via a wall socket for a least 30 minutes then try the reset again.
