I really have no idea what's going on here. I have an ASUS K75DE and both official manual and the official site says the Setup key is F2, however no matter how fast I smash the key constantly, nothing happens. I even did that process with "Fn" key pressed and again, nothing.

What's going on here?

If that's a UEFI system, you'll likely need to make sure you're actually cold booting, not rebooting or something similar . . . – ernie Jan 23 '14 at 0:21
Try Esc as well – tumchaaditya Jan 23 '14 at 0:29
thanks for you answers. ernie what you mean? I'm shutting off the laptop and then turning it on... and nothing. – Alain Jan 23 '14 at 0:46
@Alain - most of the newer systems with UEFI, even when you press power, are not a complete power off, but some sleep/hibernate state. Same thing when you reboot from within in Windows; it's not the same as a hard reboot, and often you don't have time to interrupt the boot process. To ensure a hard power off, you'll likely want to hold the power button down for several seconds. If the battery is removable, you could try that as well to ensure a complete power cycle. – ernie Jan 24 '14 at 22:10

This article suggests you should try the DEL key instead


Then, this forum is worth a read

yup, I saw that before posting the question, tried it, and nothing... that's when I pass to the F2 key and still nothing. – Alain Jan 23 '14 at 0:47

I have the same K75D series and had the exact issue for about 2 weeks. The machine is fast, and if you rapidly press F2 right after it powers on, you won't miss it anymore. The default fast boot option actually makes it harder to achieve it the first time.
