@Honda-Fan - Just had a Lenovo Tech (3rd party vendor for them) come on-site to replace the mainboard/motherboard on an M75q Tiny PC that I thought was the issue (it wasn't) but he said he works on Lenovo & Dell's. I thought of you when he said Dell's. :giggle:
Wonder if anyone else in the complex is having issues. Maybe the unit that controls your apartment and people on your floor/around you might be affected. Not sure.
