Power Key is not working after Removing Keyboard to Clean

Hello All,

I had an issue with my ThinkPad today

Quite a few of the keys had stopped responding

I decided to open the laptop up to see if I could fix it I removed the keyboard and tried to clean it

I put the laptop back together the same way it was taken apart everything was going smoothly when it was done I flip the laptop over and I go to power it on once I did that the Laptop wouldn’t respond to the power key,

I was wondering if I missed a step or what am I looking at to get the computer going again?
