I need help immediately because I need my laptop to work for exams. The problem is that recently I tried to turn my laptop on and it won’t work. I can hear the fans working (feels like they’re louder than average). The caps lock is blinking repeatedly but the screen remains black. How do i fix this??

 

thanks a lot

Iot is as if it’s a clock ticking. Blinking every second

So, one contiuous blink every second or so without any pause after a certain amount of blinks?

 

It seems to indicate a CPU or motherboard problem. Which you will need to get checked in a repair shop.

You could try a power reset:
