    Welcome to the HP Support Community 


    For that model you will need to contact HP in your region and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.


    Phone >>


    When talking to the HP rep ask them to escalate your service request.


    Just to note:


    Do not try removing the RTC battery.  It will not remove the password, but it will reset the clock - as SMC files are time coded, a large disparity between the system clock and the time encoded in the SMC  will cause it to fail.

  • Your very welcome

    Welcome to the HP Forums :) I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you're getting Boot device not found error message on your HP Pavilion notebook. Don't worry we'll work together to help you find a solution.


    To provide you with an accurate solution, I'll need a few more details:

    Have you recently made any software or hardware changes on the PC before the issue started?

    Did you try to run an extensive system test or extensive test on the hard drive from F2?

    Have you created a set of recovery media soon after purchase of this PC?


    In the meantime, let's try these steps here: 


    Perform a Hard reset on the notebook


    Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

    1. If Windows is open, click Start and then Shutdown.

    If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

    2. With the power off, disconnect the power cord from the back of the computer.

    3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

    4. Reconnect the power cord and turn on the power.


    I would suggest you run an extensive test on the hard drive from F2(Please capture the failure ID for further assistance).

    1. Start or restart the computer.
    2. Press F2 repeatedly during start up to enter the HP PC Hardware Diagnostics UEFI utility.
    3. Select Component Tests, then select Hard Drive, and then select Quick Test.
    4. Select drive C:.
    5. Click Run Once.
    6. Once the test completes, results are displayed on screen.

    If the drive fails any of the tests, this would clearly indicate a possible hardware failure with the hard drive, write down the failure ID (24-digit code).


    If the test passes, then the next option is to perform a system recovery either using the recovery partition or using the recovery media: Perform F11 recovery, or restore the system using HP recovery media.

    1. Restart the computer and press F11.

    If you can't enter F11 recovery, perform a System recovery using:


    HP supplied recovery media

    1. Select Troubleshoot.
    2. Select Recovery Manager
    3. Select System Recovery.
    4. Select Back up your files first (recommended).
    5. Select Next and follow the onscreen instructions to complete the recovery.

    If you haven't created a set of recovery media, then the only option would be to order a set of recovery media for your PC. 

    I am sending you a private message with the details required to get this issue sorted out. 

    Please check the mailbox icon at the top-right corner of this screen.


    Please check your Private message icon on the upper right corner of your HP Forums profile,

    Next, to your profile Name, you should see a little blue envelope, please click on it.


    I hope this helps resolve this issue completely,

  • 01/14/19--06:38: Re: BIOS on UP ENVY Blocked
  • Check the code again...


    I missed the fact that you posted that it was 9 digits long.


    It is only supposed to be 8 digits long, so the code program generated a code for the 1st 8 digits, which is why the unlock code didn't work.

    We have recently had a boot up problem in that when we power up our laptop, the screen remain black and nothing loads.


    Initially, the power and network light lit up and the Cap Lock key flashed intermittently.  On researching, this appears to be a BIOS error.  I have completed a hard set by removing the battery, holding the power key and then connecting to the AC cable. Also tried a The BIOS option of holding the Windows and B keys before powering on.  The first time I did this, it beeped as expected and then nothing happened stater some time.


    I have tried again today and the CAP lock key now not lighting up or flashing but I continue to hear the hard drive start and fan spin, but still nothing happening in terms of loading or screen coming on. The network/wireless key remain Orange the whole time 😬


    any suggestions?

  • 01/14/19--06:50: CMOS Battery?
  • Hi, 

    I've been having issues with CMOS checksum errors whenever my laptop's system battery completely drains. I had one the very first time I turned it on (causing a nightmare in relationship to my warranty period as the date was messed up). I've jumped through lots of support hoops and not been kept informed well at all. Finally, someone told me that this model doesn't actually have a CMOS battery and thus the system battery must have some charge left in it, otherwise I will get this checksum error and that's it's perfectly normal. Just seems like a very bizarre design choice to lack a CMOS. Any insight here would be appreciated.

    Good morning,


    Our costumer has an HP Notebook HP 15-ay078ns, he's an older person and doesn't know exactly what he's done, but he's set up a password on the laptop. When you fail 3 times when you enter the password the system shows the code [I 93572416], could any HP technician provide us with the master password? Thank you very much in advance.

    If you need to check these are our data:

    First:- Turn off the computer, press and hold the PWR button for 4 seconds.

    Then - Leave only keyboard and mouse connected, disconnect all externally connected
    devices such as Docking Station, USB storage devices, displays, and printers.
    Unplug the AC adapter from the computer.

    Next - Press and Hold the Power button for 15 seconds to Hard Reset.
    Rinse and Repeat

    AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
    Choose System Tests (Fast Test does a 4 minute hardware check).


     A little light reading...

    Turn off the computer, and then connect the power cord.
    Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
    Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
    The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
    HP BIOS Update recovery in progress

    If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
    If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.




    If in doubt please ask.

  • OK...


    42902902 would still be the same code then if the last number is omitted.


    Now, if that is a capital I in front of the code, then you need to enter this code instead...

  • 01/14/19--08:55: Re: Computer won’t turn on
  • Thank you I have got the laptop to finally turn on but now all it does is flash the hp symbol and the screen goes blank with a glow on the screen. I have tried to use the troubleshooting information but none of it seems to help.

    I meant 'on each machine'. Is there any way to have this set without user intervention? On Dell and Lenovo machines it does it silently. I can't imagine there isn't a way for HP to do this?

  • 01/14/19--09:07: Re: BIOS on UP ENVY Blocked
  • Once again thanks but it again isn't working. The initial problem is at start up. The Win10 log in screen comes up and asks for a password where there was not one previously. A hint  comes up of  0935  and the Reset password option. I have tried using  A USB stick with password reset software on it. The laptop sees the men stick but an error message comes up saying wizard can't set password for this user account. So update BIOS is probably best solution. Thanks

    Hi, can anyone tell me if there is a fix for this or do I need a new Hard Drive ?.

    The Notebook will not boot and running the Hardware Diagnostics report a Hard Drive Failure -

    Hard Drive short DST Check : Failed

    Failure ID : ME5URS- 88E9GE-XD7X7G-60X103

    Thanks for any help

  • OK.


    The code I gave you unlocks the 8 digit BIOS password code you posted.


    We can't help you get into windows if you don't know or can't reset the P/W.


    The only way around that I know of would be to clean install W10 using the Media creation tool.


    You could try a factory reset but I think that needs the Windows password to run as well.
