Which problem is solved?

the machine wasn't booting because the DSDT was missing the .aml extention, I added it and it works

 

[kickokim]

Oh, and the brightness keys are working!

when I press the "Alt gr" key on the right

Your post looks truncated. But 38=37 is normal. Maps Alt->Command.

And I assume you have the brightness slider in SysPrefs->Displays. Smooth transitions working?

Yes, sorry:
when I press the "alt" key on the left: Jan 15 19:13:04 kims-mbp kernel[0]: ApplePS2Keyboard: sending key 38=37
when I press the "Alt gr" key on the right: Jan 15 19:21:27 kims-mbp kernel[0]: ApplePS2Keyboard: sending key e038=36OK,

P.S.I see that the battery status isn't being read. What other work do I need to do now?

Yes, the slider is in SysPrefs->Displays and the transition seems very smooth when I move it

Both those look normal. Same as here. (except the part about "36OK," I assume you meant "e038=36"). Which key makes Home? Could be a language setting issue. Try setting your system to US english.

P.S.I see that the battery status isn't being read. What other work do I need to do now?

Is sleep working?
Do your volume up/down work?

Try changing your DSDT header as follows (affects keyboard layout)...

From:

DefinitionBlock ("dsdt.aml", "DSDT", 2, "HPQOEM", "1942    ", 0x00000001)

To:

DefinitionBlock ("dsdt.aml", "DSDT", 2, "HPQOEM", "1680    ", 0x00000001)

Let me know how that keylayout works wrt to Fn+keys (eg. brightness, volume, display mirror, etc).

You should see a new option in SysPrefs->Keyboard as well...

If that works ok, I'll add your board id (1942) to the PS2 drivers, making it use the same keyboard setup as the 4530s (etc).

My system is already in US english, but my keyboard is italian

Is sleep working?

I don't know about sleep, how do I test it?
Volume works

the brightness, volume work as it is now, don't know about display mirroing


What about trackpad? What should I do to make it better? The 3 finger gestures hardly ever work
Also the battery status/percentage isn't being read on the top bar

Changes your DSDT header such that it matches against one of the existing ProBook "Platform Profiles" in the ps2 drivers.

the brightness, volume work as it is now, don't know about display mirroing

The other ProBooks have a key that looks appropriate to use for display manipulation (on Windows it does something related, never tried it...). On OS X we use it to turn off external/internal display mirror.

What about trackpad? What should I do to make it better? The 3 finger gestures hardly ever work

Make sure your fingers are relaxed and separated. Practice. Also, see above about Platform Profile... it may make a difference.

Also the battery status/percentage isn't being read on the top bar

Needs DSDT patches. I already provided a link...

BTW, what about my questions regarding brightness?

 

[kickokim]

My DSDT header was; DefinitionBlock ("iASLH3cHqN.aml", "DSDT", 2, "HPQOEM", "1942 ", 0x00000001)I've changed it to DefinitionBlock ("dsdt.aml", "DSDT", 2, "HPQOEM", "1680 ", 0x00000001)


I don't have an external monitor here so I can't tell you about the display mirroring button

Yes, I know...

OK, so how's the keyboard layout? Do you see the new option in SysPrefs->Keyboard (for swapping Fn+Fkeys vs. Fkeys) "Use all F1, F2..."

Take a photo of the keyboard when you get a chance...

BTW, I think the existing ProBook battery patches are pretty close to what you need...
