I have an Alienware Sentia M3450 and for a while now I have been having problems getting it to charge. It seems as though there are problems with the power circuit board and/or DC jack because the computer does not know when it is plugged in; the battery icon in the taskbar always shows that it is plugged in and because if that I cannot tell when the plug has wiggled loose and so if I am using the laptop for any prolonged time and the plug does wiggle loose (it does not take much for this to happen) and I don't realize it, I don't receive any low battery warnings or anything; the only way I know the plug has come out in this case is when the computer completely dies and shuts off. Does anyone know why this might be happening? If it helps, the area of the computer where the DC jack is located often becomes extremely hot-- to the point where I can't even touch it.
