Very dark screen+ dead keyboard and mouse

hi you brilliant people, i've got a problem with my packard bell s netbook, for some reason i've got very dark screen, you can see it if you put a touch up to the screen, then you can see icons etc, if that wasn't bad enough the keyboard and mouse stop working as well, pleasssssssssse help i'm going out of my mind thanx

That sounds like a dead system to me. If the laptop is more than 3-4 years old, get a new one. To fix would cost as much. You either need a new inverter for the screen or a new LCD panel. The keyboard you may be able to fix by re-seating the connectors for it.
