Mistaken Bios downgrade

[silisab77]

I bought the Hp g62-a80sv about 10 years ago with Windows 7 preinstalled. My motherboard is the HP G62 605902-001 PBKJAB77RZ706G

 I upgraded to Windows10 32 bit and searched for any given updates for the bios in the using the HP program which detects automatically the hardware. Unfortunately there was nothing to upgrade.  After I changed the OS to windows 7 to see if there is anything.  I did find upgrades for Bios and I did try to install it wven if it was for windows 7. VERY STUPID  OF ME!. It was then when I saw that it was an earlier version of the Bios I currently had, but I couldn't stop the installation.  And then the laptop stopped. I do try to start it on, I can see the fan working as long as I press the button  but that's all, the laptop doesn't start. If anyone could help me I would be very grateful.

If the issue persists, after the above steps, try the below:

1. Turn off the notebook.

2. Plug the notebook into a power source using the power adapter.

3. With the notebook off, press and hold the Windows logo key  and the B key at the same time.

      NOTE:

   On some notebook models, it might be necessary to press and hold the Windows logo key  and the V key.

4. While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key  and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

   The HP BIOS Update screen displays, and the BIOS update begins automatically. This might take several minutes, and you might hear additional beeping sounds.

   • If the HP BIOS Update screen does not display, repeat the previous steps. If the issue persists after repeating the steps, skip to the next step to Download a replacement BIOS file.

   • If the Power light turns off, the notebook has turned off because the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for 2 to 3 seconds only.

Thank you a lot for all the efford to try to help me. Unfortunately none of these solutions worked for me. When I press the power button,  I can see the fun spinning,  but when I stop pressing the fan stops immediately.  I do not know if this means something.
