My week old Dell has been shutting itself down after I leave it for a few hours. I never use it for very long, so it is not a fan/overheating problem. Also, it is constantly plugged in, so it is not a battery problem. I cannot find out where the power settings are because I am unused to Windows 8. I cannot turn the laptop back on unless I first unplug the power cord. Also, the lights all turn off. (Meaning that it can sleep w/ the lights on and wakes up, but it is completely off when this happens.) I have never had a Dell before, so I am unsure if there are more settings that I am not finding. Thanks for any and all help. Have a great day!!
Call DELL support. Doesn't sound normal. There is Standby and Hibernate modes; neither of which would require you to unplug and plug-in the power cord in order to start the machine.
Dell support will have you run the Dell diagnostic at startup which will detect hardware problems. Or you could run it without calling...
Unplug power and remove battery
Press and hold power button 20 seconds
Replace battery, plug power cord in
Hold down the "Fn" key (to left of space bar)
Turn power button on while still holding Fn key
When diagnostics begins, let go of Fun key
Note any errors; let Dell know your findings
I had some diagnostic test run and nothing came up. I think that the issue is that my computer is in hibernate mode. That would explain why it turns off when I am not using it. However, I don't know how to turn hibernate off.

SOURCE: overheat?
It sounds like an overheating problem. When it is booted, does it run ok other than just being slow? Check your cooling fan and make sure it is running and not stopped up. That is a number one symtom of overheating is freezing and rebooting by itself. There is a free program called "Motherboard Monitor 5" that will monitor the temp for you and set off an alarm when it is getting to hot. Check that problem first. Hopes this helps!

Start by cleaning the fan and heat sink. Dirt or dust build up can cause them not to work as efficiently as they should. If cleaning doesn't fix it, you might consider replacing the fan and heat sink or purchasing a cooling pad.

nope, it is your dc power regulator board. you will note this happens if the battery is in or out of the laptop. that is the key test. some regulators are on the main board and some are seperate for this reason. I think the vostro though is on the main board. A little board re-work will resolve this issue after replacing some components, but this is way beyond a home user's ability.. trust me on this. Sorry for the bad news. Thanks!
