Hi there, I'm Tim and will be assisting you today. I have over 15 Years as an Engineer and have been with eBay, DoD and many others. I will do my VERY BEST to help you. If you like i can offer remote access and a call. In addition, with any positive rating I will support your question going forward for free.
Can you explain in more depth? Where are the lights? Are there sounds? Are the Fans on?
Or if you prefer, I can give you a call in abit and trouble shoot this over the phone.
But from what you are explaining so far, it sounds like a potential bad motherboard....
Please get back to me with more details, and i will circle back with you. I recommend a call so we can go over whats on and off inside the laptop.
