Hi Peachy,
Welcome to Sony Community!
We regret to hear that your attempts to fix the laptop failed. You should have included the model name of your laptop and the current operating system.
Have you already did the power reset? Have you tried to turn it on with the battery? With the battery and charger? How about without the battery (just the charger)? You may also check out this link for additional help, https://us.en.kb.sony.com/app/answers/detail/a_id/35540/c/65,66/kw/no%20power
