I had to return the dock due to these problems. Hiccups, wild fan speed, etc.
Think I've traced the problem back to having ANYTHING plugged into the either of the USB-C ports. I'm currently using a 4-port standard USB hub since the 2 USB ports on the side aren't even close to enough. Everything works just fine. However, I tried an Anker USB-C 4-port hub and everything went screwy again.
So it has something to do with the USB-C driver, bios, etc. I don't understand that stuff but it's really irritating when my brand-new, $3,500 laptop has only two usable accessory ports and I can't use multiple displays.
Does the Lemon Law apply to computers? If not for this problem, I'd rate the Precision 7530 a 5 out of 5.
I want to take the TB18DC out back and reenact the printer destruction scene from Office Space. Nothing but trouble. I'm getting my third one this week.
It's not much consolation that so many others are having similar issues to the ones I've been having with my 7730 + TB18DC. I've had it with the dock! I've posted about it at https://www.dell.com/community/Precision-Mobile-Workstations/Precision-7530-USB-Issue-TB18DC/td-p/72....
Hey Dell, are you listening? This doesn't sound like a vocal minority of people having issues with the TB18DC. It sounds like more than that.
I have a brand new 7730 with TB18DC for several months. Already replaced the docking once because of unexpected disconnections. The new one started to make the same problems. I noticed that the cable connector next to the docking is suprsingly hot. I guess it's because docking powers the laptop. I was looking for an option to stop charging through the dock, but I did'n find one, so I plugged the laptop power adaptor with the hope to reduce the power consumption through the docking. Unfortunately the docking cable plug next to the box is still hot and if I accidently touch it, docking disconnects from the laptop. Everything is updated to the latest releases.
Same here, DELL pretends its just some small issue witch will be fixed in the future. Acctually it is a hardware issue with the plug which is never fixable.
I think the truth is: All dockingstations with dual USB-C are not usable in a reliable way! The connector is to week and extremly sensitive to any movement or just a bit of wrong force causing minimal bending on the plug.
The plug is just to heavy, HP solved it different and I expect DELL to solve this issue as soon as possible.
A shortterme solution would be a Y-cable with to seperate usb-c plugs witch are connected with thinner and more flexible cables to the docingstation!
DELL is always good for some funn facts, official responce of DELL after this message within hours:
- Your product is unfortunatelly out of warranty -
this is like telling me, sorry you are right with what you are saying. The dual USB-C-PLUG is just <Profanity removed> but unfortunatelly you are to late
