I have had my laptop (Dell Inspiron N7110) for less than a year, and everything has always run smoothly. I performed a format of my hard drive yesterday and installed a clean copy of Windows 7 Home Premium. Everything went fine with the format process, so I didn't think anything was amiss -- until I tried to shut down the laptop before going to bed. And that's when I discovered that it won't shut down, unless I physically hold down the power button (which I don't like doing, for obvious reasons.) If I choose the "Shut Down" option from the Start menu, the laptop goes through the "Shutting down..." process perfectly fine, but the laptop boots up again immediately upon turning off. So it's like instead of shutting down, the system just does a restart. Which is fine for some things, but I do eventually want to shut down my laptop (I don't like leaving it on overnight in case there's an electrical storm, for example.)
I'm at a loss here. This is something that has not happened before, so I'm totally stumped. Has this happened to anyone else, and if so...how in the world did you resolve it? I'm really hoping there's something simple I can do to fix it and that it's not something going wrong with the laptop already.
