Disabling USB-C power when notebook is powered off not possible

[Anonymous]

When the EliteBook 845 G9 is shut down completely (not sleep or hibernation or anything like that, off) it's still powering devices connected via USB-C. It doesn't matter if it's currently plugged in for charging or not. The devices that are still powered are e.g. a simple USB-C hub. It's directly connected to the EliteBook via USB-C.

In the BIOS it was possible to disable legacy USB charging to disable this behavior for the USB-A ports. But the USB-C ports were not affected by that. Same thing for the battery threshold setting, it also only affects the USB-A ports.

How do I resolve this? I always have to disconnect my USB-C devices when the laptop is powered off since they will drain the laptop battery. Is this some bug that needs to be resolved in the BIOS firmware?

Hi @Treeko,

I don't want to disable the USB-C ports. I want to use them when I'm using my EliteBook.

But I want to disable them being powered (and attached devices being charged/powered) while the EliteBook is powered off.

Best regards

Hi @Anonymous 

it is recommended to disable and detach the USB port when not in use manually.

I hope this helps.

What kind of recommendation is this? Yes of course this would solve this issue but it's not a viable solution. I don't want to de- and reattach all the cables every time I power off my EliteBook. No other laptop I had in the past had this issue.

And there's even a BIOS option to disable power to the USB ports when the laptop is powered off but it just doesn't work for the USB-C ports, only for USB-A. So it seems like it's acknowledged that this is a thing users want and HP wants to offer with it's BIOS firmware but the option just doesn't apply to the USB-C ports because it's e.g. a bug.

Unfortunately I don't have a private message icon there. Only the notification bell. Either I can't access this feature or I didn't get any private messages yet.

I've received the message in the end. The proposed next step was to contact support about this issue.

I did that today. The proposed solution: When powering off, power on again and launch the BIOS settings, disable the affected USB-C ports and power off. When powering on launch the BIOS settings first, enable the ports again and then boot the OS.

I mean... yes, I guess that's a workaround but I definitely prefer unplugging the USB-C devices when powering off then instead of wasting my time in the BIOS settings after every shutdown and before every boot.

So basically there's no solution to this: I have to live with it. I still consider it a bug or a very bad design decision though: Either the legacy USB port charging should also disable the USB-C power in powered off state or there should be an additional setting for the USB-C ports. My workflow of having USB-C devices connected in powered off state is very common. So I still think this should be fixed by HP.

I second this A_cat.  This design makes no sense.  Having to unplug the USB-C (for dual monitors) everyday so the battery does not constantly drain (eventually killing the battery) is a bad design and will only wear down the physical USB-C port.  

How do we get this in a que for a potential update?  When you scour the internet many people would like this functionality.  

Thanks

From all the forum posts about different issues I also have with this laptop and that would need to be fixed in firmware, I've never seen any official responses that indicate forwarding of such feedback/suggestions/report internally leading to things getting fixed. I guess a large number of such posts might be taken into account at some point but single consumers posting to a community forum are probably not a priority. Some business that bought thousands of these machines and has an issue with the firmware is probably given a much higher priority.

Support was also not helpful: They suggested the ridiculous workaround mentioned above but there was no indication that this is forwarded internally to be fixed in the future.

So I guess for this and all other issues it's the same thing: We just have to wait. It might or might not get fixed.

Until then I've now connected as many things as possible via USB-A so I don't have to unplug them every time. It's sad having to do this with a new laptop with fancy Thunderbolt ports (and many things obviously only work via Thunderbolt oder USB-C DisplayPort channels) but it's the only viable solution right now.
