I confirmed that my Surface Book 2 with regular USB-C (DisplayPort 1.2 alt mode) can run at 1x 4K60, 2x 4K30, or 2x 1080p displays on any combination of display output ports. 1GbE RealTek 8153 for USB-C systems and incompatible Thunderbolt systems.2.5GbE Intel i225 PCIe-based works on some Thunderbolt systems.1x Ethernet RJ-45 with 2 modes of operation.Dual monitor for older USB-C systems and MacBooks.
Quad monitor capable via MST (not DisplayLink).1x TB4 downstream port (up to 15W power and DP 1.4 alt mode capable for 4th monitor).up to 100W USB-C PD charging (limited by PSU and attached devices).↳ ThinkPad X20/X30/X40 Series incl.I got the Lenovo Thunderbolt 4 Dock on launch day and did a teardown.↳ ThinkPad SL and L Series until L420/L520.↳ Forum Notices, Questions and Suggestions.FORUM RULES, HOW-TOs and FREQUENTLY ASKED QUESTIONS.And all of them use the same 230W Thunderbolt 3 Gen 2 Docking Station for Workstation (40AN0230UK). : We've posted this thread in this P1/Workstation sub-forum because X1 Extreme is basically a P1 with a consumer friendly GPU.
Ie: Do not select the default option as provided by Lenovo Vantage, asking you to approve both ThinkPad BIOS and Docking Station firmware updates all in one single step.Ī few months ago, this was one of the alleged reasons for the BIOS/firmware upgrading issues!
*****Upon 2nd Lenovo Vantage scan of your computer (after your ThinkPad BIOS update), you then do Step #2 (docking station firmware update), then reboot. It's *highly* recommended from Lenovo forums that when using Lenovo Vantage, that you upgrade Step #1 (X1E1 BIOS) first, then reboot. Our ThinkPad Thunderbolt 3 Gen 2 Docking Station for Workstation (40AN0230UK) is now on firmware v3.1.53 (the latest according to Lenovo Vantage for our X1E1).Ģ. Our X1E1 (X1 Extreme 1st Gen) is now on BIOS v1.23 and running Win 10 (64-bit), upgrading straight from BIOS v1.13 (what it came with upon purchase). Pleased to confirm successful BIOS+firmware updates for X1E1 (X1 Extreme 1st Gen) & Thunderbolt 3 Gen 2 Docking Station for Workstation (40AN0230UK).
