Disassembly

Disassembly of the SteelSeries Apex M750 is extremely simple due to the use of multiple Phillips head screws on the front and back. Do note that the ones in the front are usually underneath or between keycaps, so you have to take many of them off to access those screws, and there are also two sets of screws here - shorter ones that go in a brass/gold color thread and longer ones that are associated with a black thread. Once done, the aluminum alloy frame easily comes loose, and you can then disconnect the keyboard's cable from the internal USB connector to get the top piece off, which also has the PCB on it.


The two side pieces were held in place via these removed screws, so they come out now unless they are still in place on the cylindrical ABS plastic extensions that are used to temporarily lock them in. Once removed, two more screws per piece help reveal that there is nothing at all going on here, so it is not like some of the other keyboards we saw with side plates that light up as well. The aluminum alloy frame also acts as the plate here, such that the plate-mounted switches are all soldered through and into the PCB which is green in color. The solder quality is fairly good, with short solder peaks that terminate in the same direction and minimal pads or excess flux on the keyboard.


The keyboard has a STMicroelectronics STM32F072C8 32-bit ARM-based microcontroller with up to 128 KB of onboard flash memory and 16 KB of SRAM. Each key is associated with a QX2 switch and an LED, both of which are soldered through as seen, and all of these are on a multi-layered PCB.

Before we take a look at the driver, be advised that disassembly will void the warranty and that TechPowerUp is not liable for any damages incurred if you decided to go ahead and do so anyway.
