A:AnswerIt depends strongly on what you are doing. The specs claim 10 hours with video running, and I find it does 8-10 hours. Heavy processor use will quickly halve that.
A:AnswerOne can plug in a SD card, but it is not flush with the edge of the laptop, so I can't recommend leaving it in. I very small USB drive can be plugged into the USB 3 port, and it doesn't stick out too far. I use a San Disk Ultra Fit 246 GB.
A:AnswerI don't know if your game will run, but this is an educational laptop, not a gaming machine. Few modern games will run well on it. Your game is a FPS, and I doubt you would be satisified with the performance, if it runs at all.
