About DOs & DON'Ts when powering acomputer on &off

for me i used to long press the power button ,i ddnt know one press was enough

Also when shuting down the pc i would hold the power button instead of just pressing

Thirdly i used to unplug while turning on &turning off which i have now learnt that its harmful to my pc

but i have learned the DOs & DONTS which has enabled me to hand my pc with care

thank you so muc
