    Fan is hardware.


    All things equal, fixing the hardware fix the problem of the computer not wanting to run the Operating System.


    If the issue is indeed software related, or if the problem is not a failed fan assembly (hardware), the problem can be addressed using the solutions provided in the troubleshooting documents (links below).



    If you do not know whether you have a business class computer, you quite probably do not have one.

    Hi there, 


    The touchpad and keyboard of my laptop stops responding after waking up from sleep mode.


    This symptom took place after the last windows update somewhere early november, 


    After a cold startup everything functions normally. without any problems.


    When putting the laptop in sleep mode, either via powerbutton or lid, you can still wake the laptop with the keyboard or touchpad, after that everything stops responding.


    Mousepointer isn't visible.


    bios is updated, mousedriver is reinstalled, did the battery out-60secs powerdown thingy, reinstall to factory settings,tinkered with wakeupsettings keyboard-touchpad, none of it made any difference.


    I cant imagine that HP or their drivers is to blame, but then again, I expect to find more quality assistance here then at microsoft. :)


    Is this a more common problem, and what´s to do about ?

    Thanks for the update,


    As I understand you have tried to follow the steps suggested and unfortunately nothing has helped to resolve this issue. 


    I would suggest you try these steps here: 


    To remove and reinstall all USB controllers, follow these steps:

    1.Click Start, click Run, type sysdm.cpl in the Open box, and then click OK.
    2.Click the Hardware tab.
    3.Click the Device Manager button.
    4.Expand Universal Serial Bus controllers.
    5.Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
    6.Restart the computer, and then reinstall the USB controllers.


    Let me know if those steps worked for you.

    If they did, that’s awesome!

    Give us some reinforcement by clicking the solution and kudos buttons,

    That’ll help us and others see that we’ve got the answers!

    Good Luck.

    Dear Jeet_singh,

    I think you got it wrong.

    I am complaining about the very first boot process i.e. before Windows gets loaded (the advice you're giving to me concerns the OS).

    If you have any advice about BIOS options or anything about the process BEFORE Windows loads, I will try.

    The issue was there even with the PC out of the box (that's why drivers, updates and Windows stuff has nothing to do... except maybe UEFI settings that I don't know as I was used to W7).

    Thanks anyway.

  • 01/05/19--14:35: virtualization os failure
  • I have an HP Envy  X360 15z-bq100 and it won't allow be to boot into Win 10 Pro with Virtualisation enabled in the BIOS and Hyper V installed in the OS. I've read a few sites that state this is due to the video card drivers but I'm not sure if anyone else has encountered this issue and successfully remedied it?

    I was using my laptop this morning.  I left for the day, and when I returned home, there was a black screen that said something like "Hard Disk doesnt have an operating system" or something similar to that.  I shut down and restarted, it asked me what country of keyboard I use, then it brought to me two options: 1) troubleshoot; or 2) shut off PC.  First I tried #2 and shut off, then restarted.  Same thing.  So I tried #1. This showed options like: go to factory recovery setting; check the disk; back up, etc.  Except, factory recovery was like greyed out and not an option to click on. I tried to check the disk and it didnt do anything, so I went back and tried to back up.  It asked me which folders to back up but didnt show any folders existed, except in my usb backup drive.  So the only other was to get HP customer support.  So, here I am on this website.  


    I bought this computer in October (so I've have it like 4 months), as an "out of the box" product, which I guess means it had been returned to BestBuy.  


    Any ideas?  The computer offers me no options as to how to proceed at this point.

  • 01/05/19--16:01: Re: HP battery alert
  • Thank you for posting on HP Forums,

    Echo_Lake is at your service.


    As I understand, you're getting a battery error message 

    No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:

    • What is the product number of your device? Use this link to find it:
    • (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).
    • Have you attempted any steps on your own before posting on the HP Forums?
    • When was the last time it worked without these issues?
    • Did you run a battery test?

    Let's perform a battery test

    1. Hold the power button for at least five seconds to turn off the computer.

    2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

    3. On the main menu, click Component Tests.

    4. The Component Tests menu displays.

    5. Select Battery test.

    Battery Test - The Battery Test checks the battery and allows you to run calibration if needed.

    The Battery Check test time is 2 minutes. Battery Calibration time is 2 to 4 hours.


    If the test passes, you could continue with the following steps: 

    Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager: 
    1) In the search box, type and open “Device Manager”.  

    2) Expand “Batteries”.  

    3) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.  

    4) Click on “Uninstall”.  

    5) At the prompt put a check in the box to remove the current driver  

    6) Shutdown the computer.  

    7) Remove the battery for minute and then put it back in.  

    8) When the computer comes back up it should automatically find the driver.  

    9) Go to Device Manager.  

    10) Expand Batteries.  

    11) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there. 

    12) Click "Search automatically for updated driver software"  

    Do the same thing with Microsoft ACPI-Compliant Embedded Controller.


    Keep me posted,

    I understand you are in need of support,

    I'll be glad to help you out, however, for an accurate solution I will need more details:

    • How are you installing Windows on your PC (Using HP Recovery Media or own created media or F11)? 
    • What is the operating system on the PC?

    Keep me posted for further assistance!

    How can i fix it ( boot device not


    0 0

    I bought a new HP laptop 15-bs047nm and a small service made a Windows 10 (64 bit) installation with many updates. It was unstable. I find  a lot of malware, viruses, had TeamViewer, Remote Access and had many invisible passwords. They gave me very limited rights to do anything (install a new program or delete program, or use F keys). I did a new installation myself, but I can not get into the boot, it is protected by a password and saw system disabled [i 50767520].  I try and nothing. I haven’t safe mode or system recivery F11 cannot use too: Error code 0xc0000225.

    Has the problem been caused by Windows 10 or HP itself, or has the code been set up to control it?

    Please help to can use my new laptop completely. Thank you at adwance.

    Restart the PC, and enter this unlock passcode...67536965


    Your notebook came with FreeDOS, so if you have the W10 product key you can clean install W10 as follows...


    To reinstall W10...Use the Media Creation Tool.  Make the 64 bit installation media.



    You can make a W10 USB flash drive installer using an 8 GB flash drive using another Windows PC, if your PC is not working.


    Enter the W10 product key you have if asked to do so during the installation process.


    Here are the steps to create the W10 USB flash drive installer...


    1. Select Download tool now, and select Run.
    2. If you agree to the license terms, select Accept.
    3. On the What do you want to do? page, select Create installation media for another PC, and then select Next.
    4. Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10. You want 64 bit.

    5. Select which media you want to use:
    6. USB flash drive.  Plug in a blank USB flash drive with at least 8GB of space. Any content on the flash drive will be deleted.

    You can also save the W10 ISO file instead of making the bootable USB flash drive installer, and burn it to a DVD using the tool I zipped up and attached below if you would rather use a DVD to reinstall W10.


    Then you can reinstall the drivers and available software from the PC's support page.


    If you don't know the product key, you can find it by using the free utility I zipped up and attached below, once you can get back into your PC after clearing the BIOS P/W

  • 01/05/19--19:45: Password forgetting
  • Hi , I forget my hp password, how I open it again 

    0 0

    My notebook from time to time turns off the screen after being idle and then I can't wake it up.  It doesn't look like it makes it into sleep mode as the power light is on solid instead of blinking to indicate sleep mode.  The middle of the keyboard is warm and usually I can hear the fan as if some process is eating up CPU.  Again, it only happens after the screen turns off when plugged into A/C power and now I see that my power settings are that it NEVER sleeps when plugged in.  So it's definitely something that is triggered when the screen goes off.  And of course it's not consistent.  Probably would waste 50 hours trying to find the problem on things like this (I know from 20 years Sys Admin Experience) but hoping to find someone else on the forums that had the exact same problem and found a solution.  Otherwise I'll live with it and get my work done rather than waste my time.  Always been a Windows User but man, sometimes Apple really sounds attractive. LOL.
