If the speakers aren't working properly, it might mean that the connection has been broken, or the speakers themselves are blown. The parts might need to be replaced if there is not a connection issue between the computer and the speakers. Check the repair guide for the speakers we posted for instructions on how to access your speakers.
Be sure that the laptop is actually powered on and running. If it is and the screen still does not light up, then chances are there is a faulty wire or connection with the screen and the computer. The repair guide we have posted should help you get to the source of the problem with the monitor.
Chances are, there may be water in the keyboard. Let the laptop sit for a while in a dry area and try again, if the problem persists, that may mean there is some dust or dirt in the keyboard, and in some serious cases, damage to the keyboard's wiring and will need to be replaced. Follow our repair guide on replacing the keyboard.
