Did you see the brief message on a white screen saying that the SMC command was handled successfully? I really can't help you if you do not provide more specific information. Even in that case, I've only performed this procedure on a 4540s; it might be different on your hardware.

I just ran into this "Product Information Not Valid" problem this week with my daughter's ProBook 4540s. I'll relay the steps that I successfully used to remedy the problem, and hopefully save someone else the days of unsuccessful attempts. I believe these steps will be nearly identical for all...

Nearly all information above the System BIOS Version has been lost ,and the System Configuration ID is now incorrect.

Envy 17-J100 10.11.4 audio Be aware that 10.11.4 Beta will remove your Built-in audio device. This is fixed by running: $ cd ~/Projects/envy.git $ ./patch_hda.sh IDT76e0_Envy Creating AppleHDA injector for IDT76e0_Envy... Done. ...or at least I think that's what fixed it; I struggled for...

The USB ports all work as USB2 and USB3 before and after sleep. I noticed, however, that the touchscreen hasn't worked since installing USBXHC_Envy.kext
