You may want to reseat the power button cable. Remove the screws on the bottom with a PH0 screwdriver, then use a flathead screwdriver to pry off the upper and lower case. Use a spudger to remove and reseat the ribbon cable that connects the power button.

After your computer has restarted test and see if you updated laptop will power on without being plugged in. If not, you may need to purchase a new battery and install in
