Hi guys, yesterday I bought my new Toshiba Satellite L640 with part number PSK0JG. It runs Windows 7 Operating System in it. After starting the laptop for first time, I noticed some problems like, some unknown device ACPI\QCI0701\2&DABBA3FF&1 is attached but I am unable to find it and the drivers needed to install it properly. Also the hot-key display is not working. Since yesterday I am trying to resolve the issue but I am unable to get a solution for this. Does anyone know what is causing this problem and what I need to do to solve the problem? Please help.
