Re: nm-a181 not power on

The 3.3v will come after you press power switch, so i don't think its the regulator, it could be the enable signal coming to the regulator

Re: Hp 14-B171tu no Power on,Resistance blows off again and again

Re: Acer 5349 ZRL

When the computer is not powering on you can't get s5_on, check if you have ACIN, also check if you get rsmrst after pressing power button
