Please note the 10.8.5 supplemental update: http://www.tonymacx86.com/391-os-x-10-8-5-supplemental-update-1-0.html
This update contains an updated AppleHDA, so you will need to install your "OS X Support Kexts" using the ProBook Installer (version 6.1.6 or newer) after rebooting as you'll notice you've lost audio.
Essentially, the procedure is the same as post update to 10.8.5. See post #1.
Updated my 4540s without any issues making sure I reinstalled the OSX support Kexts.
