Hi Wuith,
After getting an Acer laptop recently, this has also been driving me crazy so I've done a little digging and, in leui of any 'proper' way to disable or change the function of individual buttons via the Synaptics driver, I've listed a registry file below that alters the function of the red 'record' button and will hopefully be of use..
To use;
- Select the text BETWEEN the '====='s and paste into a file called, say, recordbutton.reg
- Double click the .reg file just created and 'ok' importing into the Registry
- You'll then need to logoff and then back on for it to take effect (it isn't necessary to reboot)
At the moment, the registry file simply sets the button to do nothing (as all the lines beginning with ';' are just comments) but, by uncommenting the appropriate lines, you can change the button to toggle the speaker mute or launch media player (there are other possible actions also but they're not shown here for brevity)
============================================
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Synaptics\SynTP\TouchPadMMBPS2_2]
; Do Nothing
"ExButton5PlugInActionID"=dword:0000000b
;
; Toggle speaker mute
;"ExButton5PlugInActionID"=dword:0000002b
;
; Launch Windows Media Player
;"ExButton5PlugInActionID"=dword:0000002c
============================================
Hope that helps
