Dell G5 5590 + WD19TB = Error on boot

@druotolo  I work in IT myself.  Someone else asked about this specific issue a while ago, I believe involving the same combination of a G Series system and a Dell Thunderbolt dock.  When Dell systems have BIOS-level boot warnings, if there's a way to suppress them, there's a message about that on the warning screen itself, e.g. "Press F1 to prevent this warning from appearing in the future."  The warning about an undersized power adapter being connected works like this, for example.  If you're not seeing a message like that and don't see a BIOS option to suppress boot warnings either, then it sounds like the current BIOS release doesn't allow this warning to be suppressed.  I agree that there should be a way to do this for this specific sort of use case.  As for how to submit a feature request like this, Dell Support reps do read topics created here, but I don't know how often they pass requests along internally to the team that would have to be involved in implementing them. Sorry!

Hello,

thanks for your reply.

In the error message I've got, it is not written to press F1 to disable the error.

Disabling the Adapter warnings form BIOS didn't help, the error message is still there.

Indeed:

- the message is an error, not a warning

- the adapter warning is only shown when an adapter that doesn't provide enough power is attached to the system, here the problem is that the adapter is attached to a port that doesn't support charging.

IMHO it really can be solved only with a BIOS update (if and when Dell will fix this).

Actually I am thinking about returning my docking station.

@druotolo  I agree this will require a BIOS update to be resolved.  As for whether Dell will address this, who knows, but I certainly hope so.  But if you want to use a docking station now without seeing that, you'd need to find a docking station that doesn't supply any power at all.  There are some out there like that -- I think one of StarTech's Thunderbolt 3 dock models offers no power -- but they're relatively uncommon.

@jphughan thanks a lot for your reply and suggestion. I will take a look at the dock you mentioned.

I have one more question for you (and for all the community): since I am plugging a thunderbolt cable that provides 130W of power to a thunderbolt port that does not accept power, is it armful? I mean, am I frying the motherboard (or something else)?

@druotolo  no, you won't harm anything.  The way the USB Power Delivery spec works is that the power source advertises the power levels it can provide, and the device can then request the power level it wants out of those advertised options.  If the device doesn't support drawing power, then it won't choose anything.  A power source can't "force" a device to accept more power than it's designed to handle.

Very clear. Thank you @jphughan !

Hi Diego,

I just got the following response from Dell:

"My apologies we do not have   Thunderbolt docks which support   G5."

Hope this helps, Michael

@MichFosb  I have the same to this that I already wrote where you posted this elsewhere: https://www.dell.com/community/Inspiron/G5-15-5587-with-D6000-Universal-Dock-GPU-performance/m-p/7547444/highlight/true#M81839

Unfortunately there are many examples of Dell Support giving incomplete or entirely incorrect answers, especially when it comes to technical questions. It would certainly be nice if Dell were the most reliable and comprehensive source of information about its own products, but that often isn’t the case, at least not when talking with the regular Dell Support reps that most people interact with.

I have also a WD19TB running (or not running) with my G5 5590. In an unspecified amount of time the mouse freezes. Dells reply to that issue: We don‘t support that dock for the g5, the dock is only for Business notebooks...

Btw the dock works just fine with my Lenovo X1. 

why does Dell integrate thunderbolt 3 in such a poor way that they doesn‘t even support their own docks?!

There was a setting in the bios to disable the warning. It was called something like „headless operation mode“

I have G15 laptop, and the same problem with it. I see, this problem was issued like more then 1 year ago, and still last version of bios, have no function to check that if there are connected both type-c dock and 240w power adapter to laptop, maybe, I repeat, maybe owner know that, his oven (laptop) cannot be charged through type-c power delivery. As this is not critical, and have no influence to functioning of laptop, I have no idea why this message should pop-up every single time i run my laptop...It looks like time when Dell make best gone

I have the same problem when connecting my DELL G5 through USB-C with a LG Display which also is capable of providing power.

I could not find in the options of the display a way to turn off power supply, but even if I did, I do use this display with another device that is powered by the USB-C, so that would not be nice.

It is a shame that this warning cannot be turned off.

Does anybody know, how to issue bios update, for dell to add this option to bios settings?
