A:AnswerHello, Ellen. Yes, a pen can be used with our Yoga devices. You could use a Lenovo Active Stylus, or another that supports MPP or AES pen protocols.
A:AnswerAs an IT professional with 10 years in the industry, the sad reality is, blue screens happen all the time. Sometimes it could be the symptom of a greater problem other times it could just be a bug in the operating system or drivers causing a crash. I wouldn't worry about it unless it becomes a regular occurrence. Then consider reaching out to the Lenovo for support or performing a reload on the operating system. (It's pretty easy to do this from the settings inside of windows under System>Recovery> Reset this PC)
A:AnswerWireless,CMB,IN,AX211 NV according to Lenovo's parts page for this model. You may be able to find more info here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/yoga-series/yoga-7-16irl8/82yn
A:AnswerYes! It has a large screen, and has no problem driving a second monitor if you add one. I have mine on a desk with a USB to Ethernet converter that also has addition USB ports. I use those ports for my wireless keyboard and mouse. That way when I'm at the desk I can use it like a desktop, and if I move to the couch or out on the deck I can use it like a laptop. It's a powerful laptop with lots of premium specs that make it a perfect option for almost any task.
