Ordered 6 of these for the City I live in so we could do Zoom Meetings and Town business because of Covid . I was elected to set these up for town use. The Laptops work great and do all we need....however....There is a BIOS update for these out of the box, it is all easy to do and installed fine .... but I noticed that after the update, my Battery was continually discharging even when plugged in ! I had to let the Battery get to 0% and shut down, then when I plugged it in it charged normally...... this happened on all 6 laptops we bought..... so be aware and do not Panic, simply deplete the battery and then plug it back in... would have been nice if Lenova had warned of this procedure !
