Device will not power on
I have this X540S laptop, no power but I do get a battery light. The ribbon cable was bad on the keyboard so I replaced the keyboard. Now when I press the power button, the battery light goes off but then comes back on as soon as I let off the power. I have attempted the "boot strap" method trying to diagnose the problem. I have decent solder skills so if its surface mount, that is an option. We have a components shop close to my house so getting "pick and place" board parts is definitely an option. Ive also tested some of the capacitors and they all seem to be ok... Any help would be appreciated.
