Add this patches to DSDT will solve your problem:

#     Override DSDT oemId (for Clover, since it patches with "Apple ")
into method label _DSM parent_label PS2K remove_entry;
into device label PS2K insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        // Note: Function key part seems to not be necessary
        // "AAPL,has-embedded-fn-keys", Buffer() { 0x01, 0x00, 0x00, 0x00 },\n
        "RM,oem-id", "DELL",\n
"RM,oem-table-id", "HSW-LPT",\n
    })\n
}\n
end;

Please note that it will only work if Dell is consistent about their keyboard mapping.

Best to test each key with the debug VoodooPS2Controller.kext to verify that the keys are as expected.

You need to enter the scan codes for the keys that lack break codes into the "Breakless PS2" section of Info.plist.



No idea without knowing which bluetooth device you have.

Intel bluetooth is not a good choice. Better results with Broadcom. Read related links in the FAQ.

Hi !

Yes i've read that at FAQ. I don't know if it worth it in my case, but spite that, do you know how is it possible that sometimes works and others not?

Referring to the previous subject, could you address me to a post / program to debug FN keys when i stroke them

Thanks!

Intel Bluetooth is not used by Apple. Compatibility problems should be expected.

I got this one:
AzureWave Broadcom BCM94352HMB 802.11/ac/867Mbps WLAN + BT4.0 Half Mini PCI-E

http://www.amazon.com/gp/product/B00IFYEYXC?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

From the users' comments and reviews, it is confirmed working .

I want to replace the internal Intel card with that.

But the issue for me, it is really hard to remove front keyboard without damaging the plastic latches beneath the keyboard and scratching the aluminum edge, I tried a few times and give it up.
(Dell laptop design is not as good as Lenovo (IBM) design, it is hard to disassembly and upgrade)

If someone found some good tools to remove Dell 7737 keyboard, it will be really appreciated!

Did you download and read the service manual provided by Dell?

Did you download and read the service manual provided by Dell?

Yes, exactly followed every step from it and even watched a couple of Youtube instruction video.

No mistake, just did not find the great tools for that!

(For Apple Mac Mini or Macbook Pro, I can easily found specific tools for disassembling and upgrading purpose, For Levono-IBM Thinkpad, regular tools work just fine because of its elegant design. For Dell, none of above 2 cases.)

Tried it, keyboard works. but messed up with HDMI port. connecting to external monitor. not working anymore. So I roll back my code.
