UNSOLVED
Does the Latitude 5421 support S3 sleep mode in BIOS?
After a rather negative experience with the recent XPS 13 (no S3 sleep, broken WiFi, overheating), I am considering another laptop, and the Latitude 5421 seems nice.
However, the thing I am most concerned about is the fact that Dell seem keen on removing the S3 sleep mode from the BIOS altogether (because Microsoft thinks S0 should be the only option). I won't debate the merits of this policy, except to say that I need S3 in my laptop.
My question therefore: does the 5421 support S3, or has the BIOS also been hobbled?
Can someone answer this authoritatively?

Welcome to the Dell Community @sbakker
Block Sleep Enables to block entering sleep (S3) mode in the operating system. By default, the Block Sleep option is disabled.

Hi @U2CAMEB4ME,
Thanks for the reply. I noticed that the XPS 13 9310 also has that option in BIOS, but it doesn't mean anything; I believe it is a leftover from the days when S3 was still supported in BIOS. The thing is, when the OS queries the BIOS for supported sleep modes, the BIOS only reports S2, regardless of the setting you mention above.
This is why I am looking for authoritative confirmation whether S3 is still supported on the (recent) Latitude models.
