I have an X56 / H12Y which is total junk. PC world replaced the touchpad 4 times, and the keyboard twice. When it came back the last time no audio, no device found, and no screen backlight. At this point I got fed up and in the end PC world gave me my money back. They didn’t want the laptop back. I have now had the defective card , below the screen in the top, replaced and the screen now works however still haven’t found a fix for the audio problems.
