HP ProBook 4535s problem after installing some updates!
Hello.
I have HP Probook 4535s, OS Windows 7 Professional x64
After downloading and installing updates(official HP page) for the bios (V. F.22 15 May 2012) and windows (Essential System Updates for Microsoft Windows 7,V. 2.0 16 Apr 2012) dvd tray began to open itself for several minutes after starting the Windows Media Player.
Any help please?
