Public bug reported: I am running 19.04 on a Lenovo X1 Extreme. The laptop has an Nvidia 1050 Ti Mobile graphics card. I am using the Nvidia driver version 430 via the graphics-drivers PPA package nvidia-graphics-drivers-430 of version "430.40-0ubuntu0~gpu19.04.2".
When the computer has the Nvidia drivers active via prime-select, a large amount of power is consumed in suspend mode. I have attached the output of this script: https://www.thinkwiki.org/wiki/ACPI_sleep_power_drain_test_script (battery-test.log) which estimates that the computer uses about 4.5 W on average during suspend. On the other hand, when the Nvidia card is not in use (prime-select is used to switch to Intel graphics and bbswitch is used to ensure the Nvidia card is off), the power drain during suspend mode is 1 W or less. Therefore, it looks like the system fails to power-down the Nvidia card before suspending when it is being used.
