  • To check CPU Generation go to Settings: System: About
    Examples to decode generation:
    Intel® Core™ 14xxx x.xxGHz -> 14th Gen
    Intel® Core™ Ultra x 2xx x.xxGHz -> Core Ultra 2
  • Some Core Ultra 1 and 2 computers may limit 4TB and 8TB SSD speeds to around 800 MB/s. Full performance is expected with 1TB and 2TB models.
  • Charging rate varies according to overall power usage. When sleeping, any connected computer that supports Thunderbolt charging will be charged to 100% by the dock.
  • Thunderbolt compatible adapter required (sold separately).
