Delay in booting up after pressing power button
If your laptop or pc or server shows a long delay in booting after pressing the power button, it's possible it could be underpowered. I realized mine was 600W and after changing some green for non-green hard drives, the bootup after a cold start was taking longer and longer. I purchased a new PSU of 750W and that resolved the issue though I never tested the 600W PSU if it was bad and took a few too many power surges. Likely my motherboard was underpowered for the new hardware.
