A couple of days ago I got my 9370 and encountered the same problem with wakeup after suspend.

I researched a lot and experimented a bit but in the end the fix turned out to be simple and I still can't find a downside - which makes it look weird that this wasn't configured from the start.

First you can get the Ubuntu iso from Dells support page (I put in my service tag - dunno if it shows without doing that first).

With that you should be able to reset your laptop to it's original configuration - including Dell drivers (I assume - didn't need to try this myself).

After that go to "Software & Updates" -> "Additional Drivers" tab. There's a list of special drivbers listed there - with several options.

One of the is for wifi. It was original selected with a blacklist option for ath10k (I'm writing thios from memory - after switching to the next option I don't see the driver listed there anymore - which surprised me).

I changed that to another option that mentioned "killer".

That was it. Since then wakeup from suspend works fine. My wifi shows no trouble so far. So far no downside after a day of heavy use.

Couple more tips:

The super key comes originally disabled - seems to be some annoying licensing issue (and we would have preferred an Ubuntu or Tux label anyway ;-.) ). Which **bleep** because it's useful and Ubuntu uses it to open the Dash etc...

Here is Dells own link to fix this silliness:

And I was super annoyed with the fn keys being preferred over the media keys - easy to fix: fn-esc toggles that.

Please note that the right side USB-C doesn't show the power (lightning) symbol. I don't think it's available for charging

Let me check with the team and get back to you.

Stay tuned!

Hi,

I'm experiencing the exact same issue on my XPS 9370. Dell changed my NVMe SSD today but the issue still occurs. They proposed me to change the motherboard, but I'm hesitating since it sounds like multiple people are affected by the issue, making it very unlikely that a motherboard switch will indeed fix the issue. Hope Dell can and will fix this with a BIOS upgrade. Any news @DELL-Barton Ge? If you need any further information on my hardware, please let me know.

In addition to unplugging the power cord at boot, it's also possible to open and close the BIOS without doing anything in it. Just after that, the laptop will boot properly (until it occurs again). That's weird.

Hi,

Just to give you an quick update, somebody from Dell changed my motherboard on Monday. Since then, the issue seems to be fixed. So yeah, affected people like the OP should definitely get in touch with Dell support to get a motherboard replacement.

Thanks!
