Hi Justine! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. I'm sorry that you are having this problem. It would be my pleasure to assist you with this. Please remove the battery, remove the power cord, and press and hold the power button for a FULL 30 seconds. This should should discharge any remaining residual power and "reset" the laptop. After doing that, plug in power cord but don't reinsert the battery. Next, press and release the power button to turn it on. Please give that a try and let me know the results.
