A:AnswerMy System came with Windows 10 Home. The settings says that it can be undated to Windows 10 Pro by either having an update key from a previous Windows version or buying the Pro from a store. So, NO, mine did not come with Windows 10 Pro.
A:AnswerIf you use it all day, working all the time with several programs, internet and so on, mine lasts about 5 hours, and after I need to connect it again to the power supply.
A:AnswerWhen I spoke with Dell they said to use a "universal" docking station. It connects to the USB 3 port and then provides two HDMI ports and a couple USB ports for keyboard and mouse.
I have two 24" DVI monitors I want to run with my laptop and so their solution means I also have to use two HDMI to DVI adapters which I haven't yet found. Seems cumbersome.
I'm thinking there must be other similar docking stations out there with DVI ports instead of HDMI.
A:AnswerYes it is possible to replace the hard drive on these still. The cost to do this yourself ranges from $250-$400 for the SSD. If you don't know how to re-image or install new OS you will need to pay geek squard to do it for you. Probably another $100-$150 for that.
