You can check the warranty and support contract status of your HP products online. This includes the base warranty, support contracts and/or carepacks.
No_Light means there's no link on the port. Usually this indicates a problem with the physical wiring, either a faulty cable, or the TX/RX have been swapped.
No_Sync means there's a link on the port (so technically, wiring is okay), but there's a problem with the actual communication. The most common problem is a mismatch in speed on the switch port and the HBA on the other side. Your best bet would be to set the port's speed (temporarily) to auto-negotiate and see what speed is selected. If this does not work, try manually setting the port fixed to lower speeds.
It may be useful to know whether your Mac has a 32-bit or 64-bit EFI. This can be done by running the following command from an OSX Terminal (can run from the installer or recovery partition):
ioreg -l -p IODeviceTree | grep firmware-abi
This should return something like the following:
|• For 32-bit EFI:||| | "firmware-abi" = <"EFI32">|
|• For 64-bit EFI:||| | "firmware-abi" = <"EFI64">|
Recent models of Mac boot up with a black boot screen and white Apple logo, instead of the old gray and dark gray boot screen. DarkBoot enables older Mac systems to get the black boot screen as well. For newer Macs, the app can also change the boot screen back to the traditional gray color.
Known to work with OSX 10.10 and 10.11 DP.
You can disable the page prompt "--More or (q)uit--" by entering the following command at the console:
terminal length 0
This disables the prompt, and allows you to do config dumps, or run show tech-support.
If you get an error about unrecognized command, your firmware is too old.
Dell Networking switches introduce a new port mode called switchport general. This type is a multi-purpose mode, combining access and trunk in one.

I followed this guide to replace the HDD on my Mac Mini (2009, aka model A1283):
The most tricky part is probably opening up the Mac. As I did not have a putty knife at hand, I used a rack cage nut mounting tool to create an opening, and a very thin flathead screw driver to pry the case off, as explained in the guide.
EDIT: added picture of tool.
A very interesting read about Wi-Fi implementations and its pitfalls in larger deployments, in particular about the usage of channels and the importance of channel plans.
To get this card running on Windows Server 2012 and 2012 R2, you need this driver:
Newer versions no longer seem to support this card.
If you have an HP laptop with an unknown device with hardware-id HPQ6001, it's the HP wireless button driver. Apparently some models on their support website lack this driver in the download list (it was the case for a HP Envy Touchsmart 1230eb).

If you happen to stumble upon an unknown device in Windows Device Manager with a hardware ID of ACPI\INT33A0, it's the Intel Smart Connect Technology device. Download its driver from Intel or from your manufacturer's website.
A note about installing the drivers for the Dell PowerVault TL2000/4000 on a Windows 2012 machine.
You can download the firmware from the Dell Support website. After extracting the package, do not install the driver using Device Manager. Doing so will not properly install the drivers (results in error code 37). Instead, install them using the included executable (install_nonexclusive.exe). Running this (elevated) will install the drivers the proper way, and the devices will start correctly.
