Razer keyboard, trackpad buttons, touchscreen are on the USB bus. Their power is controlled by USB hubs. The trackpad itself is not. Its power is controlled by ACPI, that is a black magick of chipset, BIOS tables, and OS drivers. There are glitches in ACPI subsystem, newer Linux kernel knows how to handle them. If not, you can give it a hint. Try a live Linux to make sure your hardware is [most likely] OK. Just download, say, Ubuntu, make a USB stick and boot from it. You do not need to install it, it works right out of the stick.
