T450 Will Not Power Up

[shajoe44]

My T450 will not power up. I have replaced the battery and have done all the power resets found here and online. I would really love to save this computer if possible. Is there anything internally that can be looked at to get the laptop powered back up.

Thanks

Are you getting any lights when you plug in the juice?

Having the exact same issue after pulling my T450 out of storage! Only behavior it gives is flashing the power button LED green to show that the AC adapter is connected, and occasionally attempting to boot will flash the mute/mic mute LEDs. I've tried it with the internal, external and CMOS batteries connected and disconnected and no change in behavior at all. No signs of obvious physical damage.
