I hadn't heard about this S mode before, which basically locks you into safe programs from Microsoft. You can't download anything from other sources. Not even Chrome, for example, which the computer insists you don't need, with a pop-up admonishment. "For your own good," as your mom might say. To get out of this took research. You can't even use REGEDIT in Admin mode (which it considers not to be a Microsoft program!). For someone not very techie or computer literate, S mode is probably very useful, but for me it was quite a hindrance.When I found the steps, the mouse would not click the button to get out of S mode. After two days of madness, I was ready to return the laptop, but then tried plugging in an external mouse. With the external mouse, I finally turned this S mode off. This is a permanent change, no going back.Now it's nkta bad machine. But when I tried pair it wirelessly with my new Fire TV, it could not complete the pairing, though the TV recognized the device. After 20 plus attempts, I've given up for now and bought a long HDMI cable.  Possibly there is some setting I can change to make that work, but it's quite disappointing. I use my TV as a large external monitor when home.Battery life is fair. The plug is huge, and won't fit in some strips. I don't even see where the battery might be. I hope it's not the kind that requires a tech to replace.Though it's large (which I like for the screen size), it's fairly light. It fits into my large backpack, which has a padded computer compartment.  It's light enough to carry around, if unwieldy.Because it's solid state, it usually is ready for me pretty quickly, but longer if it was fully powered off.  I'd give it 3 1/2 stars, but the annoying S mode thing made me choose 3 over 4 stars.For the price, it's not bad. I bought it thinking it was this huge Amazon sale, but I've since determined the price is similar everywhere, or even cheaper.
