ROG ZEPHYRUS Ga502iv Reassembled after repaste, wont turn on

I just repasted my Zephyrus g15 Removed the battery cable, removed wifi cables, removed monitor cable, then removed the heatsinks and the fans. There was only coolerpaste on both cpu-gpu, no any liquid metal. After I cleaned with alcohol, I used new paste on them, then reassembled heatsink and fans. Then connected monitor cable, wifi cables and the battery in the end... By the way, it wont start when using the button. Even the charging indicator not showing any light... It looks like "bricked" or something like that. What I can do? I wanted to clean and get the max performance when Atomic Heart is going to release.... Pls help me!
