both fans are on but nothing else works

Texto:

my laptop has refused to power on.,..so I opened it...I notice that the 2 fans are rotating but the screen doesn't turn on...the startup sound isn't heard....the keyboard doesn't light up. I've tried connecting it to an external display and nothing still happens!
