Purchased this Laptop Back in February 2020 as Personal Laptop. I must have used the Laptop no more than  15hrs in total from 2020 to 2022 due to my work schedule I use Levenno T540p and this laptop has seen more usage and the Keyboard is still working.I reached out to Acer Repair Center Explaining to them the situation --> Summary Upgrade to Windows 11, the laptop was working great, I closed the lid and opened it later on that Day to a non-functioning Keyboard. Gave them all my workaround but nothing worked.Only be told that the cost to repair starts at $739.99. This is the last time I would invest in an Acer Product and would advise against purchasing it.
