Suitable dock for ThinkPad X1 Extreme Gen 3, usually used with low-medium load

2021-05-17, 10:03 AM

Hello!

I have ThinkPad X1 Extreme Gen 3, it comes with 170 W power supply.

 

Most of the time the laptop is working under low or medium load (10-40% CPU and GPU). Occasionally I put it under full load for 20-30 min, 2 or 3 times a day.

 

The laptop has the lid closed, so I'm not using its monitor.

I'm wondering if I could use the 135 W docking station. I assume it should be enough for low-medium load, and for short periods of high load it could use some battery power maybe.

If I connect the 135 W dock (see the link below), will the laptop work with the same performance as if 230 W dock is connected and just use the battery when necessary? Or will it work with reduced performance (compared with the 230 W dock)?

We have the slightly older 40AN0230UK Thunderbolt 3 Docking Station for Workstations Gen 2 an it works perfectly fine with our X1 Extreme Gen 3.

 

I would personally suggest 170W AC Adapter to power both your X1 Extreme Gen 3 and this 40AN Thunderbolt 3 Docking Station, in case you connect external accessories which also relies on your ThinkPad and/or Docking Station for power draw. And this includes any USB power charging phone accessories for your Android/iPhone!

Especially if you plug in additional Thunderbolt 3 accessories such as ThinkVision M14 external LCD monitor which relies 100% on USB/Thunderbolt3 for power and power signal.

Disclaimer: Some power users on this same Lenovo/ThinkPad forum were using both ThinkPad workstation and this same class of 40AN Thunderbolt 3 Docking Station for Workstations Gen 2 which came with 170W AC Adapter were complaining that "it was not enough to power their ThinkPad, Docking Station, and other connected accessories [presumably also while charging ThinkPad workstation's battery too].

 

I feel that a single 135W AC adapter to power both your X1 Extreme Gen 3 and this 40AN Thunderbolt 3 Docking Station would be very tight power draw scenario.

It might not be enough power. Suggest you use at least a 170W AC Adapter, and perhaps even consider to use 230W AC Adapter for power users.

 

- - - - - - - - - -

To give you an idea of power draw:

 

1) We use the slightly older (and apparently discontinued) 40AN0230UK Thunderbolt 3 Docking Station for Workstations Gen 2, which came with two (2) power AC Adapters:

~65W AC Adapter for powering the 40AN0230UK Thunderbolt 3 Docking Station for Workstations Gen 2, mainly in case you plug in other devices which draw power from this Docking Station (as described above).

~Another separate 230W AC Adapter which powers your ThinkPad connected to the Docking Station (essentially it's a Pass-Through power connection for your ThinkPad). It's 230W because different ThinkPad workstations can be connected, hence for "worse case power draw consideration" the 230W AC Adapter was used. Also, your ThinkPad might have other devices which draw power directly from ThinkPad as described above.

 

2) For our own X1 Extreme Gen 3 (we use i7 CPU with FHD LCD for battery savings--but we digress), it came with a 135W AC Power Adapter, which from personal experience is enough to power X1 Extreme Gen 3, two (2) units of M14 external LCD monitor, and even a USB cable to charge our Andoid/iPhone all once!

Conclusion:

I feel that a single 135W AC adapter to power both your X1 Extreme Gen 3 and this 40AN Thunderbolt 3 Docking Station would be very tight power draw scenario.

Thanks, Lorenzo!

I'm wondering if the 135W version will work fine or not, considering the way I use the laptop (see the original post).
If the performance with the 135W version will be the same as with the 230W version (for short high-load periods, except for the extra battery drain), then I would just get the 135W one.

Hello,


The ThinkPad Thunderbolt 3 Workstation Dock (Type 40AN) has two Lenovo SlimTip power connectors on it, labeled 230W and 65/135W, respectively.

 

In order for the dock to power the ThinkPad X1 Extreme Gen 3, a 230W power supply will need to be plugged into the 230W SlimTip connector on the dock, and a 65W or a 135W power adapter will need to be plugged into the 65W/135W SlimTip connector on the dock.  The 230W power supply provides pass-through power to the ThinkPad, while the 65W or 135W power supply provides power to the dock. 

 

Also, a ThinkPad Thunderbolt 3 Workstation Dock Split Cable (Type 4X90U90621) must be used to connect the ThinkPad Thunderbolt 3 Workstation Dock to the ThinkPad X1 Extreme Gen 3.

 

Regards,

 

Aryeh Goretsky
