I bought a new Dell XPS13 two weeks ago and discovered the hard way - after totally flat batteries - that sleep mode doesn't work. Whereas my other XPS13, the previous year's model, works perfectly.

What is totally annoying is my monitor, which has USB C power delivery, won't charge the laptop if its battery is completely flat. So now I have to carry the XPS's power adapter too.

I have been an XPS fan for years. But I am so close to sending this one back.

(If anyone from Dell reads this, pass back the message that you've lots of really unhappy customers from this)

Adding to my comment on my XPS13 7 days ago:

* I raised a service ticket with Dell.

* They asked me to install the latest firmware for the XPS13 9310, dated 8 April 2021.

* That solved the problem: now I can close the lid and the laptop properly sleeps; I can put it in my bag without it getting noticeably warm; battery loses just a couple of % overnight, not 75% as it did before.

So irrespective of whether this 11th gen does S3 sleep or not, my laptop is now performing in line with what I expected.

Thus: thank you Dell.

I believe that on (some?) Intel 11th gen chips, S3 sleep states are disabled, and only S1 works?

S3 = traditional "suspend to ram"

S1 = new fangled "kind of sleep, instant on mode"

At least, thats what I found on a System76 Lemur Pro, which has the same cpu as the XPS13 (and System76 had to restore the IME, whereas before they used to disable it, just to get some semblence of sleep working)

Solution: get an AMD 4800 - powered laptop instead. Same price, double the cores (8 vs 4), much (much) faster and yet runs cooler.

And S3 sleep works!

Sorry to hear it's happening in the latest generation product too. This is really disgraceful by Dell as the issue has been known about for years and they don't seem to care. Same with the crappy thermal pasting job that their factory does.

Do not expect the issue to be fixed. People bought XPS's years ago thinking Dell would release a patch in some reasonable amount of time, but it never came.

If your use case involves a lot of time away from a charger, I would send it back. Maybe splurge a bit more for a Surface Book, assuming Microsoft cares a little more about putting out a well finished product.
