HP ProBook 4540s - system does not start after recovery

My friend gave me the laptop, because system was not detected. I decided to recovery operating system.
I had to deal with following error messages:
- I was getting error "Boot Device not Found"
I started HDD test with result Passed
- next step was to recovery OS
it finished with new error message
"Selected boot image did not authenticate. Press to continue"
 according to this topic:
http://h30434.www3.hp.com/t5/Notebook-Operating-Sy​stems-and-Software/Selected-boot-image-did-not-aut​...
I did following:
- secureboot changed to disabled
problem  persisted
- legacy changed to enabled
since then I am not able to do anything. When I let the system start, it finishes with HP logo and nothing happens.
When I press ESC after restart, menu is displayed but I am not able to enter to BIOS. If freezes all the time on the menu with highlihted text.
I tried to remove battery, unplug power, press 30 seconds powerbutton, nothing has changed.
Next step should be probably to temporarily remove RTC battery, but I am not sure if am I allowed to open it without loosing waranty.
The laptop is old approx. 3 months.
This question was solved.

Hi:
Since the notebook is under warranty, I would suggest your friend contact HP technical support and have them fix the issue.
When you get a boot device not found error it is either the hard drive (whether the test says it passed or not), or the drive controller on the motherboard.
I wouldn't touch it with a ten foot pole.
The HP support tech will probably have your friend run through some of the steps you did before they tell him what to do next such as returning it for warranty repairs, etc.

  • Windows does not start after recovery

    Hi, my son's sattelite 1800 started getting slower and slower to the point where it took almost an hour to boot into Windows. It got to the stage where it looked like recovery from the CD's was the only route - so we did. All looked successful from the recovery point of view but Windows XP Setup displays 'Please wait...' with normal looking disk activity for 20-30 seconds and then hangs - no disk activity, mouse stops responding. I've gone through the recovery in 'expert' mode and don't see any issues with the recovery process. Questions:
    1. Has anyone else seen this?
    2. What else can I do diagnostic-wise?
    3. What, fundamentally, does the recovery process do/ (does it re-format partitions, might it have left a virus?)
    4. Am I best following h/w or s/w diags?
    Bitshifter

    Hello
    On this way it is not easy to give you a proper explanation why this happen. If you use the recovery CD for OS installation the HDD will be formatted and the OS will be clean installed. IF you use standard mode the whole HDD capacity will be used for just one partition. Using expert mode you can create two partitions or you can install OS on persisting partition.
    Usually after recovery reinstallation there should not be any problem except for HDD malfunction.
    Please wait message occur after first start and you can not compare it with usual boot up process. That first start after recovery procedure takes much longer time because the OS must detects all hardware components, install drivers and prepare the OS for the usage.
    For further start the OS doesnt need so much time for boot up process.
    Bye

    My UPAD lite does not start after recent update. I have lots of info in it. Can anybody help me to get it back? Can I somehow undo the update? Thanks

    "UPAD lite?"
    I expect that you mean some version of iPad.
    First, 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 the screen blacks out or 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.  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.

    Hi,
    You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
    Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
    one used by the Form contact for Form Invoice.
    Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
    VS General Question forum mainly discusses
    the usage of Visual Studio IDE such as
    WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
    System and Visual Studio Editor.

  • RAC does not start after trying to move storage

    Hello,
    We have a two nodes RAC Oracle 10g and ASM groups defined on one external storage.
    RAC does not start after we reformated the storage to RAID 10.

  • 16 GB x-Fi Style - does not start after charging

    Hi,
    4 weeks ago I bought my x-Fi style and used it during my holidays for 2 weeks. After charging the player only twice (USB-connection with notebook), it now fails starting. Maybe there is an internal temperature fuse to protect from overheating and I only have to wait to try again? After connecting to USB the CREATIVE sign appears but disappears directly and a battery symbol appears and remains on the screen. After disconnecting the player does not react in any way. I already tried to reset but cannot start it again.
    Can anyone help me?
    Cheers,
    Uli

    Re: 6 GB x-Fi Style - does not start after charging:Just fyi
    I found the website for Creative to be very frustrating. Not one snail mail address or corporate headquarters info. The link for website feedback didn't work and one other customer service link was a dud. They clearly don't want to be 'bothered' with complaints, or anything positi've for that matter!
    But, I searched on the forum and found a three-year-old post about someone who was frustrated with having to carry around a paperclip to always push 'reset' on his X-Fi -- and the light dawned! Didn't know I had one of those. I pressed reset and voila! it is working again. Still had to charge it, but it accepted the charge this time and I was able to finish my book and move on to the next. Now, the next problem is I tried to access my wireless network which has a $ in the password and there is no $ in the choices for entering a password. So, now I have to change the password, change all of my device passwords (Blu-Ray, iPad, laptops(2), friend's laptops, etc. a huge pain. Seems to me they could have included a $ in the choices!

  • My MacBook Pro, does not start after pushing start button. The side bar starts and stops at half way.

    My MacBook Pro, does not start after pushing start button. The side bar starts and stops at half way.

    Hy myneck,
    Happy Holidays!  The resource below may provide some steps to try if your MacBook Pro won't start.
    Troubleshooting: My computer won't turn on - Apple Support
    http://support.apple.com/en-us/TS1367
    This article discusses what to do if your Mac won't turn on. To differentiate this from a display issue, be sure that when you press the power button:
    You don't hear a startup chime.
    You don't hear any fan or drive noise.
    There is no video on your built-in or external display
    If your computer has power but doesn't display any video, it may have one or more of these similar symptoms when you press the power button:
    You may hear a startup chime.
    You may hear fan or drive noise.
    You may see a light from the Sleep LED (if your Mac has one).
    Pressing the Caps Lock key on the keyboard causes it to light. 
    If any of these display-related conditions occur, see Troubleshooting: My computer has no video instead. Otherwise, continue with this article.
    If your computer won't turn on, try each of these steps:
    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. 
    Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
    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).
