    My laptop is refusing to turn on. When I plug in the AC adapter, the indicator light comes on for a few seconds, then turns off. I’ve tried to boot from AC power with the battery removed with no luck. The front battery indicator light is blinking. Any suggestions? I did back it up, but I need specific files and have moved to a new laptop with a different OS.

    So i've had my laptop for a little over a year now but after I messed with some boot settings in the bios all went wrong. It all started whenwI changed some boot options, something about switching legacy to uefi.

    After I had done that, the laptop wouldn't read my hdd anymore so I'd thought I would just go ahead and change it back in the  bios but everytime I tried to enter it, it would highlight the option (which was f8) but then just sit theee and never load the bios so I'd thought about reseting the bios, taking out the cmos battery, removing and putting the memory back on, just about everything you can think of. At the end of the day i was getting 4blinks which referred to the memory so I stopped messing with it and the next day i opened itiup completely and reseated the memory but then this led to me getting 5 blinks. Its been a couple days since I've tried fixing it and I just want know if there may be something else I can attempt before I buy a new board (hesitant on buying a new board because I don't think the current one I have is messed up)

    Hi. I have updated my laptop bios from HP support site and I lost my product ID, serial number etc at startup. I lost some important windows files too 'cause my laptop could't start to windows some time after that update. I had to download and re-install windows and that is done now, but I still get this error message at the startup "Product information not valid; The following product information programmed into the system board is missing or invalid.

    System board (00A) -Product name

    System board (00A) -Product serial number

    System board (00A) -Product number

    System board (00A) -System board CT number

    ENTER - Continue startup"

    And my laptops all numbers are just a bunch of y letters (picture attatched).  Can you please tell me how do I get those information back where they belong? Than you!hp_vika.jpg

    I'm having a problem with HP Pavilion laptop , Intel i7-6500, 16 GB RAM, Windows 10 installed.

    Maybe somebody had experience with the situation before.


    Every time I try to boot it hits me with a BSOD, many different errors (page fault in non paged area, system thread exception not handled, system service exception, ).

    Even if I try to boot from USB or Windows 10 recovery DVD, it immediately hits a BSOD.


    Laptop HP component tests passes all the tests.

    I ran Memtest - passed. I tried removing one RAM stick at a time and booting - doesn't work.

    I tried updating BIOS - doesn't work.


    Even tried disconnecting HDD and booting from recovery - doesn't work, still BSODS.

    I'm running out of ideas, please give me some advice.

    - Press (Windows Key + Arrow UP Key + Arrow Down Key) all keys at same time and turn on the system
    - Release all keys and press F10 at HP logo to go to F10 setup to (Reset BIOS security to factory default)

    Try different brand and smaller size USB key USB key is not formatted FAT32 Make sure to use USB 2.0 port and not USB 3.0 port on notebooks that have both types of ports.
    BIOS ,date and time should be current and updated.
    Use hard drive method by using HP_TOOL partition, if there is no HP_ tools partition,  it can be created in either of 2 ways:

  • 12/20/18--13:33: TPM and bitlocker issue
  • I installed a new SSD with windows 10 pro and when IU try to use bitlocker to encrypt, it won't save the code to an external drive and fails. If I bypass the check it will encrypt the drive but it continually looks for the key every time it restarts. I'm about at my wits end because it has a TPM and this is the second install that has been done to try and fix the issue


    No updates left according to the solution center and the TPM version is 2.0 I believe
