Acer Aspire T180-G7Z auto powering on

Hey Community!!


I am currently fixing 2 Acer Aspire T180-G7Z PCs and both of them seem to like to power on as soon as there plugged into the wall. Its as if the motherboard pins for the front pannel are tripping on their own, weird that 2 of them are doing it... 

Any ideas? it isnt the PSU because i changed with a brand new PSU.

Thanks in advance!!

Check the BIOS power settings.  Not sure about laptops, but on Desktop machines there is an option to automatically turn on when power is restored.
