Notebook: FN Key and Shutdown Patch


Recommended Posts

Hello, I have a HP Probook 4540s laptop. It's a very versatile notebook and OS X works like a charm.

I think my Function Key (I have only one on the keybord) works out of the box. What I mean is this: I press FN+F1 and notebook goes to sleep. I press FN+F9 and volume increases. And so on.

My question is: Do I need this patch ?


# Enable functions keys
into device label PS2K insert
Method (_DSM, 4, NotSerialized)\n
   Store (Package (0x02)\n
           "AAPL,has-embedded-fn-keys", \n
           Buffer (0x04)\n
               0x01, 0x00, 0x00, 0x00\n
       }, Local0)\n
   DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))\n
   Return (Local0)\n


As I mentioned earlier, my function key works without that patch.

Another question, here's the shutdown fix:

#  Shutdown fix
into method label _PTS code_regex_not If\s\(LEqual\s\(Arg0,\s0x05\)\) code_regex ^((?:.|\n)*)$ replace_matched
       If (LEqual (Arg0, 0x05)) {}\n


Both FN key and Shutdown patch are in the laptop section on Olarila.

I never experienced problems with shutdown, so I need that shutdown patch? What does that shutdown patch really do?

Any suggestion would be greatly appreciated. Thank you!
