Hi all, I have a HP notebook as030tu and I recently switched from VoodooPS2controller to the latest version of Smart touchpad. Everything works perfectly except the Brightness control keys. In the past, I have Fn+F3 for brightens up and Fn+F2 for brightness down working with a DSDT patch. And now, both keys will only do mute/unmute function. Yes, they have the same function now. This problem exists still with DSDT patch. into method label _Q13 replace_content begin Store(HKNO, Local0)\n If (LEqual(Local0,7))\n {\n // Brightness Down\n Notify(\_SB.PCI0.LPCB.PS2K, 0x20)\n }\n If (LEqual(Local0,8))\n {\n // Brightness Up\n Notify(\_SB.PCI0.LPCB.PS2K, 0x10)\n }\n end; The brightness control is working, but these keys will also do mute/unmute function. Is there any way to fix this mute/unmute problem? Thanks. PS: sorry for my English.
