I recently acquired/was given an older M17xR4. I'm not familiar with Alienware in general. Everything seems to work ok on it, and it has a GTX 680m and a i7 3920xm with 32GB. Only problem so far was Win10 acting weird and locking up, bringing the BIOS from A08 to A13 seems to have resolved that. Also, a USB port on the left (closest to the rear of the machine) doesn't seem to work. I also have to kinda play with the power cord to get it to recognize as an official Dell one, otherwise it complains on post.... I'm guessing the power supply might have a broken cable internally. Anyone have any pointers on what I should do to this? I have an old msata I'm going to put in and a couple of 1TB drives. Also, I figure that it could use a complete repaste. Any reasonably priced upgrade for the video card?
