get in touch with the supplier for support and call the manufacturer or send it back to the manufacturer for this, a collegue of mine had a similar problem and thay ended up replacing the laptop as it was a hardware failure, on laptops the parts can't be replaced (usually). pc's are easier to problem solve as parts can be replaced with ease laptops however are not designed that way.
assuming it's a new laptop and still under warranty call them and go through it with them, they will either solve or send you a new one under the conditions of the warranty.
