Hey

I opened my laptop from the back side cus it was heating up a lot.I know it was my fault.But when I closed it again the screen was not turning on. For first time caps lock was blinking rapidly like 2-3 times in a second and now it's not even blinking. 

When I opened up my laptop a thing fell out of it I don't know what it was. 

 

I would really appreciate if anybody could help me.

Thanks

Hi@Kitratsu,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing Overheating issues with the HP ENVY X360 Laptop not booting to windows. 

The BIOS can be corrupted during normal operation from a failed BIOS upgrade, or damage from a virus.   

Recover the BIOS using a key press combination. 

Turn off the computer. Press and hold the Windows + b keys, and continue to press those keys while you press and hold the power button for 2 to 3 seconds. Release the power button, but continue pressing the Windows + b keys. 

The power light remains on, and the screen remains blank for about 40 seconds before anything is displayed. You might hear a series of beeps (usually 8 beeps). Eventually, an HP BIOS Update screen is displayed and the BIOS update begins automatically.   

NOTE: If the HP BIOS Update screen is not displayed, press and release the power button, and then immediately press the Windows + b keys at the same time, repeatedly, until the computer beeps or opens the HP BIOS Update screen. 

After the BIOS is recovered, a Continue Startup button is displayed and a timer counts down. Click the Continue Startup button to restart the computer immediately, or wait for the computer to restart automatically when the timer reaches zero.

If the issue persists then it could be a hardware issue on the PC. As we have limited support boundaries in the support community as of now. I would request you to contact our HP Support Engineers and should be able to sort this out.

Please reach out to the HP Technical Support team in your region regarding the service/replacement options.
