I knew there were remarks on screen brightness and they're true- poorly lit. Less than 2 weeks and keyboard started to get wonky by giving apostrophes '''''' endlessly. Ran software scans, device manager updates, and Amazon is telling me to contact Microsoft. I assume they'll tell me to contact Lenovo. This is how my last lenovo died (after 6 years). I've had this one less than 2 weeks. Caveat emptor.
