Hello jono here, i am from indonesia. I need help about my laptop problem.

My laptop suddenly went shutdown. When i try to turn on again, the display was blank and capslock blink 2 blink.

when i turn on the laptop :
1. Cpu fan spinning fast for some second like usual.
2. Then the fan become too slow for 4 - 5 second.
3. After that capslock light blink 2 blink and cpu fan spin faster again.

My laptop type was hp 14-ac146tx core i3 5005 and have another amd gpu. I read on community hp that capslock blink 2 blink was bios problem. Try to recovery bios but the driver download page for hp 14-ac146tx was empty. I search that my laptop...
