The desktop is ideacentre 700-25ISH, I bought it for less than two months and actually I was out of town for several weeks last month. It is basically brand new.
I run the hardware health check from lenovo companion and got the error code WMB010000-WM7VJI. The reason that I run the test is just because the machine may power off abruptly everyday. And I once got a message like USB port power surge after login.
When the machine is down, I have no way to power it up. The only thing I can do is just unplug everything and use the desktop tomorrow.
