I just got a ThinkPad T14 Gen 1 AMD.

Issues

• Sleep mode drains the battery
  • The T14 has S0ix ("Windows") and S3 ("Linux") sleep modes
  • S3 sleep drains more power than S0ix (Fixed in UEFI Firmware 1.40)
• Sleep mode sometimes doesn't work
  • This seems to be a kernel version problem (Fixed in kernel 5.14)
  • Sometimes the laptop does not go to sleep, even if the lid is closed, this seems to be a distro / power management problem
• Waking up from S0ix sleep takes ~10 seconds
  • Waking up from sleep is instantaneous on Windows
  • Waking up from S3 sleep with UEFI Firmware 1.40 and kernel 5.14 is instantaneous
• TrackPoint stutters
  • There is a workaround
• Screen ghosting / burn-in
  • Only visible on a gray screen
• Edges of the palmrest are sharp, unlike previous ThinkPads where the palmrest edges are slightly curved

Improvements over previous ThinkPads

• Battery charge control now works by firmware
  • works without booting into the system
  • can be configured under /sys/class/power_supply/BAT0:
    • charge_control_end_threshold
    • charge_control_start_threshold
• Thinner and lighter
