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.
Charlie, How old is this unit?
OK, so its probably out of warranty then. Those notebooks usually do not last a long time, 3-5 years, i'm unsure who in your area can service these, but its almost ALWAYS cheaper to replace.
That was just my last response, i had to step away, I Don't know what to tell you other than it sounds like plausible bad hardware, I could remote in and check.
i'm also very happy to opt out and let someone else help you.
I can do it for 5.00
