Everything works perfectly, except for an issue that I haven't been able to fix today, two months after testing it. Every time I restart the computer, it gets stuck with the "Protected by HP Sure Start" logo. I contacted Amazon customer service and they recommended draining the power by disconnecting the power cable and holding down the power button for several seconds. Then, I reconnect the cable and the operating system starts up without any problem. I have to repeat this process every time I turn off the computer. I still have one month left to decide whether to tolerate the problem or return it.
