Is there any way a can bypass post on my Acer 5520 laptop?
Do you mean the boot screen? Which OS are you using? POST is a Bios function, on bootup go into Setup and see if there is an option to disable POST.
I use windows vista and is there?
I don't know. Go into your bios at startup and see if there is a POST option.
Take Jethro's word for it.
