A:AnswerWe use the Wacom bamboo ink smart stylus and it's pretty responsive. We also have an ipad with the Apple pen and I think the Wacom pen is actually better feeling in your hand and it's responsiveness. It works on tiny AAAA batteries, so there's no recharging it, but you can always carry a spare if needed.
A:AnswerYes it has the keyboard, no the pen is $100 I think. I don't think you need the pen, it works fine without it. I have no idea why it's cheaper online, but we got it for only $550!
A:AnswerThe fan running when the system is working is normal. You will hear that fan when it is running, this too is normal. If the sound of the fan is different when you download a file, we recommend you call Lenovo Tech Support for more specific help. The number is 877-453-6686.
A:AnswerThis is a high performance system with its Intel Core i5-7200U processor and 8GB of RAM. It will generate heat whenever it is turned on, even at idle, this is normal. The onboard fan will maintain the proper operating temperature for the device. You will hear the fan whenever it runs, this too is normal.
