Hi jsnapp556,
Welcome to Sony Community!
We are sorry to hear that your laptop won't turn on anymore. We appreciate your effort to troubleshoot the unit. To sum up, the unit won't turn on with the laptop plugged in with (or without) the battery. Same result with the battery alone (not plug in), right? How about any indicator light on the laptop when you tried to turn in on? Try to twist the power jack to make sure there is a good contact between the ac adapter and the unit. If the issue still persist then service is required. You may bring the unit to an Authorized Repair Center to have it checked.
Regards,
Jen
