Good afternoon, I cleaned the Deadd 5240 laptop and replaced the thermal paste, and when it was turned on, it said to press f2 to reset the bios settings (it seems it was), but I pressed Enter, now the computer does not turn on. Tell me what to do. I have bios firmware skills. and tell me which board needs to be flashed, I understood them there 2. Is it possible to have a simpler option. thank you
