I have my work laptop (that I've had for 2 years) set to go into "sleep" mode after 2 hours of non-use. It used to work like it should but about a month ago it stopped going to "sleep". I have it set this way because I hate going through the process of booting up a computer in the mornings and re-starting all my apps when I come into work but want the computer's hard drive and other moving components to shut down during the night to help prolong the life of the laptop -- I think that will help the computer. Now, when I come into work in the mornings the computer seems to be running, as it would during the day, and the screen saver is running instead of the screen being blank like before. Before, I would hit the "enter" key and the computer would roar up and come to life and now that doesn't happen. The screen saver setting is set to turn on after 30 minutes of non-use. The display setting is also set to "never" turn off. It's always plugged in and both the battery and "plugged in" settings are the same. I had an older laptop at home that would do this as well but chalked it up to its age. What's going on? Any ideas/suggestions?
