Laptop Questions? Ask a Laptop Technician for Answers ASAP!
Are you able to use the laptop at all or does it flash a black box then power off?
Since you cannot read the box, it would be easiest if I connected to your computer to see the issue then fix it. If you are okay with that, please accept the offer that I am sending you then I will provide you with the steps so I can connect. It can take 1-2 minutes for the offer to appear.
