You're welcome! There is one more thing you might try on the Latitude if you have Windows admin privileges. Check if you have Intel Thunderbolt Software installed--it may appear in the Windows task try while you're connected to the WD19TB. If you can change the authentication mode to "No authentication," that might do the same thing as the boot setting in the UEFI. Unfortunately I can't verify this for you on my work equipment, but it's worth a shot especially if IT isn't willing to adjust your settings.

I didn't realize you were running Ubuntu. Your system is new enough that I think either Linux or Windows will feel just as snappy on a new, fresh SSD install. And if your memory is working, replacing it won't do any good. You're welcome!

I think whether it's worth upgrading will depend on some of the notebook's other specifications. It's also worth deciding on a budget so you can figure out whether upgrading to something newer is feasible. If you're not already on Windows 10, you should look in to upgrading. You should also do a fresh install of your OS to improve performance if you haven't done one in a few years. If you have only 4GB of RAM, you are probably regularly running in to the limit. Your notebook supports a single DDR3L 1600MHz SODIMM (PC3-12800). Any module will do, but here is Dell's own upgrade for your machine to use as a spec reference. The next thing I would consider is a solid state drive. Any 2.5" SATA SSD, especially the nicer TLC or MLC models, will breathe new life into the system if you are still on the factory hard drive. This upgrade can go hand-in-hand with a Windows fresh install like I mentioned above. Some options include the Samsung 860 EVO, Crucial MX500, or SanDisk Ultra 3D SSD/Western Digital Blue 3D. Since you already have the i7, I doubt you will see a meaningful performance increase replacing the motherboard. You would have to go to a board with the NVIDIA graphics if you don't already have one. Make sure to find out if the same upgrade has been successfully done by somebody else before.

Question 1: Since you are able to get the dock to work sometimes, your 5480 must have Thunderbolt. Models with Intel U or H series processors and only integrated graphics do not. The System Configuration -> Thunderbolt Adapter Configuration page includes an option to Enable Thunderbolt Adapter Boot Support. It is disabled by default. The first thing I would try is to enable this setting. Question 2: According to this PDF, your dock does support 2x4K displays at 60Hz if your system supports DP 1.2. Note the double **, which reveals that Question 3 is correct and you need one display connected to the Thunderbolt Type-C port on the dock. There are two Type-C ports on the back and only one is TB. That means that for Question 4, yes, you need either a USB-C to DisplayPort cable or a USB-C to DisplayPort adapter that you can connect to your existing cable. If you choose an adapter or cable from a reputable company, I'm confident it will work per this post about about the WD19TB. This should fix the resolution issues on both your machines. Since you have all Dell equipment, you have the best dock for your needs. The Dell docks have custom power delivery that works only with their laptops, and any third party dock you get will still charge but with less power. Finally, you should definitely not buy a Dell USB-C dock because none will work with dual 4K displays and both your machines appear to have TB. The D6000 is a decent dock for productivity use, but in high performance scenarios, the WD19TB will be better since it is not DisplayLink.

Thanks, Linus. That's what I expected when I didn't hear it mentioned in the video. Even though I don't work in production, the Linus Tech Tips workflow and server videos are an instant watch for me.

This is very cool to see! Linus talked about how the NVMe SSD NAS is replicated in real time to a hard drive server, and that that server is also replicated to a server off-site. But do you also back up your ~400TB archive anywhere in-house or offsite? If so, how (or why, if not)? I missed that in the video if it was mentioned.

The Samsung 830 series, overall, actually performs a bit better than the 840 series. The reason is because the 840 uses TLC flash, which doesn't perform as well as the MLC flash found in the 830. That's part of the reason why the 830 is more expensive than the 840. If he's looking for performance better than what he has been getting, then a Samsung 840 Pro would be a better option; the 840 Pro is the actual successor to the 830 series. The regular 840 is a completely new product line and has no predecessor.

I hate it when Windows updates have that type of problem. A few weeks after Windows 8 launched, I was getting update after update; in general, that's a good thing—it means that things are being fixed. But I got caught with a couple of updates that would get stuck at the same percentage during the install, stay like that for hours, finally fail, and then the PC would restart. I knew it wasn't my computer because other people were having the same problem online with a variety of different configurations. Thanks for sharing, because I'm sure lots of people would be happy to avoid wasting more time than usual issuing updates to Windows.

In my experience, Find My iPhone is good only for giving a general idea of where the device could be. I would never trust the location data it gives alone as justification to knock on someone's door and accuse them of taking the device. You can kind of see where the phone is, but once you're in the vicinity you would have to either call it or use the app to force a notification ring at max volume. The app's location data would really only be accurate in places where the houses are pretty far apart, and even then I wouldn't trust that as enough justification. I'm pretty sure you would only be arrested for it if they actually proved you stole the phone; therefore, it would have to be in your possession or sold by you to someone else after taking it. They would need more solid evidence than Find My iPhone to prove that. If the police is smart where you live, they would realize that the data is not completely reliable. The app should only be treated as a helpful investigation tool, not a reason to go around and harass individuals whose homes fall within its hundred meter range of error. As long as you didn't take the phone, you have nothing to worry about.
