Hi, So recently my keyboard and mouse pad for Sony VPCEB4E4E have both been unresponsive. I have tried hibernating it and this has allowed the keyboard to work, however the key pad remains unresponsive. After pressing F2 at the Reboot, and Setting default has stopped the keyboard from working again after hibernation. As of now I am using a graphics tablet, this is really frustrating, So any help is appreciated! Thank you.
