Delay upon power up

[asheenlevrai]

Hi

 

I just finished this new build (see below) and Ihave noticed the following: When the rig is OFF and I press the power buttons it takes a long time (like 5 seconds) before the PC turns ON.

 

I'm wondering what could cause that. However, this is not a big deal, but I'm curious.

 

parts:

ROG strix B550-I gaming

R5 5600G

XFX RX590 Fatboy

2x16GB DDR4 3600 (Trident Z)

Seasonic SFX-L PSU (SGX-650)

 

Thoughts?

 

Best,

Ooh ooh I think I may know this one:  microsoft shortened loading times once several years ago by arranging so the boot sequence wasn’t gone through every time.  Instead of doing a full boot it saved a hibernation file so when you thought you were doing a full shutdown you weren’t.  Instead you were just waking from hibernation so the boot sequence seemed shorter and the machine seemed faster even though it wasn’t.  So sometimes when you think you’re booting your PC you actually are, and sometimes you’re just loading a hybernation file from a previous actual boot.  There was a way to make it do an actual boot. I don’t remember what it is though.

Thanks @Bombastinator

However, I doubt this is what's going on here.

The booting time is fine (quite fast on this brand new rig actually).

What takes 5-8 seconds is for the machine to turn ON after I press the power button.

What I mean is

 - I press the power button

 - nothing happens for 5-8 seconds

 - the power button lights up and the POST process starts

 - the control LEDs (DRAM, CPU, VGA, BOOT) on the MB light up sequentially, together with the other LEDs (AIO fans, AIO pump)

 - the machine starts booting windows

 - -> ... bla bla bla -> login screen

 

I was wondering if something is wrong with the power button. Maybe I should try testing with a different one (or a different case) but I get a hunch that this is not it, for some reason.

 

Thanks again

Power button is just a momentary switch. Basically you’re just shorting pins.  Not much to go wrong there.  If it’s all pre windows boot though a windows hybernation mode wouldn’t play a role unless the board manufacturer is pulling the same trick with its BIOS, which I doubt.
