I have a Lenovo T450s laptop I picked up second hand a couple months ago. I've been having an issue with my computer where the power usage is extremely high while in standby (it empties the battery in approximately 8 hours). Upon further investigation it looks like it is exiting CPU power state S3 immediately after sleeping. I've included some dmesg logs for the standby process below.

[ 40.681642] IPv6: ADDRCONF(NETDEV_CHANGE): wlp3s0: link becomes readyThings I've tried to fix this: BIOS update, disabling every device except LID inside of /proc/acpi/wakeup. Any advice on this issue would be highly appreciated.
Also I'm not sure if it's relevant, but there is also an issue with my idle power usage being around 8W while not doing anything according to powertop, even though all the CPU powerstates are a majority in C10. I've seen people with this laptop get approximately 4, so 8W at idle is pretty high to me and may be related. Powertop is suggesting iwlwifi is the issue but I've seen that it isn't particularly accurate in the individual readings for devices. Disabling WiFi through rfkill does not appear to help (approximately 1W power drop, max), though I haven't tried disabling it through the BIOS.
Thanks.
