You only have to install the Razer synapse software if you want to make macros and use those kind of keyboard features. And the keys are very quiet on it.

It's hella loud but works real nice plug it and no soft ware download just plug in and use

It works ok as a normal keyboard. The chiclet keys have no sound.

However, if you use a dual-boot computer or set BIOS menu options, computers don't always recognize the keyboard until the operating system (e.g. windows) starts.

yes you can no software needed .... soft key no clicking sounds

You can hook it to any computer without installing Razor Synapse as long as the computer is connected to the internet to automatically download the drivers it needs just to operate and yes is it a soft touch keyboard without sound when pressing keys.

Yea I think it's pretty much a plugin and go keyboard. I don't remember having to install any kind or programs. And yes it does have a pretty good clacking sound to it. But it's a fairly soft sound to me. Probably also because I type lightly on the keys

This keyboard needed no extra hardware for windows 8.1and ubuntu 14.04 and 14.10. It does not make a whole lot of sound, but it does make some sound. It certainly is not the clickity-clack of the more expensive model, but it is louder than the average laptop keyboard. I would expect that it may be quieter than the standard workplace keyboard.

It is very quiet and no you don't need the software.

Yes, Windows should pick up on the drivers. Not sure about linux

I'm not sure about the software but the Deathstalker's keys should be soft touch and if you are looking for sound by Razer go for the BlackWindow.

Yes it will turn off.

Custom, settable for preferance

It turns off.

The backlight can be set to stay on, dim, or turn completely off when computer goes into sleep mode through the use of the Razer Synapse software that can be downloaded with every Razer product.

They turn off. Good way to tell from across the room if your screen is off, or your comp is asleep.

No it stays on :/

Yes it does, and in fact after a low power sleep they don't come back on.

Yes. You download a program called "Razer Synapse" and It has an option to dim the keys when the computer goes idle.

It will turn off. It does so about 2 seconds after you remove your hands from the keys. It will then light up immediately after you touch it.

You going into razer synapse go under the keyboard settings and then to lighting. It will give you options on what to do from there.
