Solved! Water spilled on my Lenovo laptop then after 2 weeks the keyboard light was on but the screen turn black what should I do

Solution
Not much to do, liquid damage will cause issues. Likely you need a new motherboard. Need to have someone look it over to see what the issue may be. You probably have visible corrosion on the motherboard or other parts. Keyboard going bad can cause boot issues as well.
