I have an HP g7 laptop that I've only had for a year and the warranty as well as the Best Buy protection plan is just about up. The problem is about once every week or two it will shut down due to overheating. Every time it has done it it's been when I have it hooked up to the HDTV with the lid closed. I'm starting to think that with the lid closed there's not enough ventilation. I've never had a laptop do this before and it's only happened during the last couple of months. I do notice that on this laptop the fan is almost always constantly running but I had another HP before this one and its fan was running excessively as well. I can usually figure out most computer problems on my own but I've never ran across this particular issue before. Any help would be greatly appreciated!
