My Dell Studio 1737 completely powers off when you shut the lid. I already went to the settings in windows 8.1 to choose what the laptop does when the lid is closed. It still completely powers off. It won't let me turn it back on unless i plug it into the charger. Once it boots, i can take it off the charger and use it like normal, but if it gets shut again, it will completely power off.The laptop won't even charge if it is closed. It is like the power is completely cut once it is closed. I am using a brand new battery as well. Thanks!
