Thanks Travis for listing down your BIOS settings. The changes I made
to match your settings:
Config - Power
8254 Timer Clock Gating -> Auto <<<< this was to Disabled in my BIOS
Config - USB
Always On USB - Disabled <<<< this was Enabled in my BIOS
Security - I/O Port Access
Memory Card Slot -> Disabled <<<< this was Enabled in my BIOS
Boot
UEFI/Legacy Boot -> Both <<< this was UEFI only
UEFI/Legacy Boot -> Priority UEFI First
I installed 6.6 on an external drive. After some intensive use
(Chromium streaming 4K video), fan kicks in. However, when closing
down Chromium (or at least the 4K tab), FAN will stop running after a
short while and won't stay up consistently anymore - similar to 6.5's
behaviour.
@Dave, what are your BIOS settings? If different, would be interested
to know if those given by Travis would lower the ~15W idling to ~10W
on 6.6 ...
I have just gone through and set the following on my T430:
- Reset to Defaults
- Security - Secure Boot Configuration
Secure Boot -> Disabled (was enabled)
- Startup
UEFI/Legacy Booot -> Both
UEFI/Legacy Boot Prirority -> UEFI First
- Config - USB
Always on USB - Disabled (was enabled)
- Config - I/O Port Access
Bluetooth -> Disabled (was enabled)
Fingerprint Reader -> Disabled (was enabled)
Memory Card Slot -> Disabled (was enabled)
I don't have an 8524 Timer Clock Gating setting.
Booted into 6.6 and my power draw seen from `sysctl | grep batt` was
unchanged, hovering around 15.19W idle sitting in the X session.
Did then notice this machine's bios was a 2017 version... went and
updated to the latest 2.82 21 Aug 2019
Not an appreciable change to the battery consumption. Hovering around
14.98W. Fan is slightly different though - it's not constantly running.
Comes on and off.
Cheers,
DT
