From 0fe1d4b9fe56a0f27a6ff39cfb94d63559b729b8 Mon Sep 17 00:00:00 2001 From: Nicholas Chin Date: Fri, 3 May 2024 16:31:12 -0600 Subject: [PATCH 66/67] mb/dell: Add S3 SMI handler for Dell Latitudes Integrate the previously added mec5035_smi_sleep() function into mainboard code to fix S3 suspend on the SNB/IVB Latitudes and the E7240. The E6400 does not require the EC command to sucessfully suspend and resume from S3, though sending it does enable the breathing effect on the power LED while in S3. Without it, all LEDs turn off during S3.
