Had this happen to me this morning and took it to the Dell Walk In Center here in Seoul. Guy said it was a processor failure but he'd have to get with his boss and back to me on my options.
Pretty much what are my options? I also took it to a local repair shop, he said he can't fix and take it to Dell. Estimated the cost would be over US$ 250
Like others have said about their M5010's mine is a little over 2 years old and out of warranty.
thanks
