Hp pavilion x360 laptop

[Ak28112001]

It's been a year I bought this laptop and one day it suddenly stopped working. It shut down while I was watching a movie. I didn't know what to do so I charged it completely and it started working but after a few days the problem repeated and the screen displayed a message saying The CMOS checksum is invalid. The CMOS will be reset to the default configuration and will be rebooted. Please check your B10S Setup options to see if they change.

CMOS Reset (502)

ENTER - Reboot the system.

The laptop had stopped working. It didn't even start. The caps lock showed 3 long and 5 fast blinks. I searched on hp website for possible solutions and me and my friend updated my BIOS using USB. After this laptop started turning on but whenever I move it, it shuts off and I see 3 long and 5 fast blinks on caps lock. My power button has inbuilt light which has stopped working. Sometimes it starts and it works fine but suddenly it turns off and I see flickers or pixels. Please tell me some solution fast. I am a student and I need my laptop to study for my upcoming exams.
