I've been buying Dell products since about 1988, for companies I've worked for and personally. New and Outlet items. I believe that relationship is now at an end. I ordered a Precision 7530 and TB16 at the end of January, received them last Tuesday, February 5, 2019. 7530 is an Outlet refurb. I've got a number of Latitude and Inspiron from the Outlet and have a Precision 690 tower years ago that have all worked well. Sadly, over the past 4-5 years, I've experienced less than pleasing issues with some items (things happen), but the support has been the real troubling issue for me. This latest purchase has about pushed me to the end of my desire to ever deal with Dell again. Started the implementation of the 7530 last Tuesday afternoon. Started, let Win 10 Pro install, setup, configure, etc. Went through updating Windows, BIOS, firmware, drivers, changing BIOS settings for accessing the TB16. All seemed well. I have two (2) 16TB NAS units sitting on my desk for our business use. I have 4 other Dell laptops, two Latitude (Win 7 Pro) and two Inspiron (Win 10 Home and Pro) that connect fine and are very stable. I also use a Logitech M570 wireless trackball using the Unifying dongle. Fist, issue was that the trackball became unstable. Dongle is plugged into one of the TB16 USB 2.0 ports. Cursor would stop moving, hang, freeze, begin working again then freeze for good until reboot. Contacted Logitech and they responded saying: 1) They do not recommend plugging dongle into docking stations; 2) they do not recommend plugging dongle into USB 3.0 ports. Ok, I've been using this trackball with Unifying dongle since 2014 with a Latitude E6540 in the port replicator docking station without any issues at all. Additionally, my wife has an Insprion 14 (7000 series) Windows 10 Pro, with a Plugable docking station, exact same model of trackball/Unifying dongle plugged into the docking station and it's rock solid. Ok, pulled a wired Trackman Marble off another Inspiron and swapped. Much more critical issue cropped up with not being able to maintain a connection with the NAS units. If/when I was able to establish a connection with either or both, the connection would not hold. If I got up and went to lunch and the 7530 sat (I change the settings so it does not sleep, just the monitor sleeps), when I came back the connection to the NAS units was lost. Contacted Seagate and WD support, went through troubleshooting steps and both pointed back to either a Windows or hardware issue in the 7530. Called Dell tech support yesterday, Sunday, my only "day off". After 5 1/2 hours of them working on various trials, registry, and other attempts and an attempted restore of Windows 10, they finally concluded I need a new HD with Win 10 Pro image. Technician verified my email address with a test message, told me I would receive an email yesterday afternoon with confirmation of the new HD order and one following with tracking info. Also said I would possibly receive the replacement HD either today or tomorrow. As of 10:30 this morning, I had not received any email from Dell, so I opened a chat with tech support to follow up. No help at all other than it appears the order has been placed. But no idea when it may ship. So, I have a 7530 and potentially problematic TB16 that have been completely useless for a week. I have spent numerous hours on my own trying to ensure I had all the updates, latest drivers, 3rd party support issues resolved. I then spent last night and all this morning transferring software licenses and files back to the Latitude. And Dell hasn't got a clue as to when I will receive the replacement hard drive. If I do not have an email sitting in my Inbox at 4am tomorrow (when my work day begins), with tracking info, I will be contacting Dell for a full refund and return instructions. This is not the first time I've experienced these types of issues in the past 4-5 years, but it will be the last time. The tech
