Comment 3 for bug 1871491

Kent, Alex, thank you very much for your help.

I have just updated the bios with the version 1.8.2 published today for 7740 on the Dell Website. Now the syspend-resume process works correctly in any situation. Definitively, a bios issue, I guess.

I am going to check if all is okay over the next days.

@Kent: I have Nvidia driver 435. The resume problem was both with switchable graphic enabled and disabled. It occurred when Nvidia card was used, but also when Intel card was used (nvidia-prime was used to change the used card on nvidia-settings, when switchable graphic was enabled in the Bios).
