My Mac Book Pro just stopped booting up. there is power getting to the unit but no screen comes on and no control. I have had no problem on the system, but it is a few years old now, 4, I think. Anyone out there had something like this happen?

Thanks for getting in touch, my attempts to get the unit to chime were nil, but I brought it to a dealer and it did chime, but still no screen. They are authorized Apple tech folks and putting it through some tests today, I hope to know more soon. PS: the note above was very helpful pointing out a failed graphics card as an issue that has been recognized with Apple and they are prepared to replace it even if your warranty has worn out. I might be in that group, Thanks again,
Richard

Thank you very much for your notification, I went there and I think I am in that group. The computer is at the doctors, I'll post what the results were. Thanks again, Richard
