What does the button on the left do?

If I remember correctly (had this case a few years ago) it's a reset button, press it to hard reboot the computer.

I don't think it is the reboot button because of its long press the button on the right it reboots it. I pressed the button on the left and it doesn't seem like anything happens.

The button needs to be connected to the reset pin header on your motherboard for it to work, if it's not connected the button won't do anything.  If you want to fix it you can open up the case, find the cables that come from the buttons/LEDs and check where the reset one is connected (I think the plug is labelled).
