A couple of months ago I updated BIOS of my HP Laptop 15-bs111ur on F.60. I am sure that I downloaded F.60 from the official website. Around the same time, after BIOS upgrading I started to hear loud fan noise. I performed many steps to fix it:
- Updated all drivers;
- Reinstalled Windows 10 Home Edition;
- Used all tests from HP Support Assistant;
- Thermal paste was replaced;
- The fan was replaced (yes, I even installed a new fan for CPU).
Nothing helped.
Recently, I noticed, that F.60 version was gone from the list of versions supported for my bs-111ur. And now, obviously, I am pretty sure BIOS should be reset. I tried to reset BIOS with the following ways:
- Reset a laptop with a removable battery;
- Win+B+Power button: HP BIOS Update screen does not display;
- Reset the CMOS using Win+V+Power button: reset was successfully executed. However, BIOS is still F.60 version, and I am still can not reset it via "Win+B+Power button".
- Recover the BIOS using a USB recovery drive: HP BIOS Update does not display.
How I can reset BIOS? Or maybe there is some way to downgrade F.60 on F.52?
