Hp stream x360 wont start up hard reset done, win+b done

[Nasty_nachi14]

Battery was built-in.

Tried holding the power button for 20secs amd more but all it has done was for the caps lock key to keep blinking.

I've tried win key+b, kinda worked, made my pc starup and display message like there is something wrong with the bios or sonething (haven't really caught the whole msg but you got the gist). It just flashed for a couple of secs and then it got stuck on a blank screen the whole night. Now i kinda tried to press random keys then it just displayed like ESC...EXIT BOOT (then got stuck, I have to try the win key method again) i pressed F9...CHANGE REBOOT ORDER then got stuck again. I kept pressing the said key but it still kept displaying the message on the bottom left corner of my screen.

I've been searching and scouring the net for trouble shooting advises but majority of them are generic hp support. Kindly help me.

Hey There! @Nasty_nachi14, Welcome to HP forums!  

I understand you have issues booting into your PC and the light on caps lock is blinking.

Don't worry I'd like to help you out.

Did you make any software or hardware changes on your PC?

How many times does the light on caps lock blink?

Please provide the product number of your PC to assist you better.

Two blinks on caps lock LED indicates BIOS corruption.

If a BIOS corruption error occurs, you might not even notice the blink codes, because as soon as the computer recognizes the error, it restarts, attempts to recover the BIOS, and then restarts again. You might notice an extra-long startup process as a result, and a message indicating that the BIOS has been recovered might display on startup. If this occurs, update the BIOS on the computer. 

If the computer does not automatically recover the BIOS, manually perform a BIOS recovery.

Turn off the notebook.
Plug the notebook into a power source using the power adapter.
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.
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.
If your notebook starts Windows, update the BIOS to the latest version using the standard BIOS update procedure. For more information about updating your notebook BIOS, go to Updating the BIOS (Notebooks).
Click Continue Startup to prompt the notebook to restart immediately, or allow the notebook to restart automatically when the timer reaches zero.
After the notebook restarts, press Enter to continue.
   NOTE:
If the notebook repeatedly displays a message that the BIOS has been recovered, go to HP BIOS Application Selected is Corrupt or Missing for troubleshooting steps.
After Windows starts, if a message displays stating that the notebook was improperly shut down or that a boot problem was detected, follow the on-screen instructions.
You can now to enter the BIOS menu or start the Windows operating system.
