Use of dock 40ANY230US with a P17

2021-06-06, 21:32 PM

I have a pretty fully loaded P17 and would like to use it with the dock listed in the title. Before buying the dock I chatted with a Lenovo sales rep and that was one of three compatible docks. There are a few unfavorable reviews that speculate that it doesn't put out enough power for the PC, though. They could be completely wrong, but there seems like there may be a way to provide more power. Included with the dock is a 230W power adapter just like the one that came with the computer. But the way to hook it up is via a splitter that provides power to two different connectors on the dock, one listed as 170W/230W and the other is 135W/65W. The splitter has output cables labeled 170W and 65W so it *looks* like the splitter gives me the minimum into each power port. What if I just go to Lenovo and buy another power adapter which is 135W, use that in the lower port and the provided 230W adapter on the upper port and skip the splitter altogether? Would this be a good thing or a bad thing?

 

BTW, the computer is new and I bought a 4-year warranty that I do *not* want to void. So it would have to be both a good idea and a defensible good idea. I tried submitting a support ticket with this question but weirdly couldn't figure out how to format the phone number. I'm hoping some tech support folks read this forum and can give me a definitive answer.

 

Thanks!

Yes, you can power your 40ANY0230US with two AC power adapters!

~Suggest 65 W AC Power Adapter (if you have a spare one from your X1 Carbon 65W you can use that too), + 230W AC Power Adapter.

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

 

~65W AC Power Adapter (slim-tip) 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).

 

~230W AC Power Adapter (slim-tip) 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.

In your P17 case, you definitely need 230W!

Thanks! It turns out the only extra power supplies I have around are either 230W from my P70 or 45W from my X270. Lenovo has a pretty good sale on accessories right now so I ordered a new 135W adapter and will try that with the 230W instead of the splitter. That way both power supplies are within the range of the labels on the dock.

 

It seems like this is at least reasonable to try. I have premium support and accidental damage coverage from Lenovo. Even if this is wrong I think it would be considered an accident since it's within the range of the labels.

Lenovo has a compatibility chart and a sheet given to their dealers. I have seen one in the past. You might see if you can get that before wasting money on another power brick you don't need. It may work well with just the 235W power brick.

Probably. In honesty I don't know as much as I should about electronics so might be asking a stupid question. The setup docs list three very different ways of connecting the dock and no real advice to help me choose. My impression is that under-powering most electronics is a bad thing so I want to err on the other side.

 

The three options are:

    Use the splitter and Y cable included with a single 230W power supply, power the PC from the dock.

    Use the 230W power supply *and* a 65W power supply into the dock, power the PC from the dock.

    Use a 135W power supply to the dock but *don't* power the PC from the dock. Use a separate power adapter directly to the PC.

 

I think how well these work will depend on the demands of the PC and of the peripherals on the dock (bear in mind my lack of electronics knowledge, though). My PC is very loaded. The stock power adapter for the PC alone is 230W. The second two options seem safer to me even though they don't use everything in the kit and require an additional power adapter. Is this wrong?

 

I guess I'm a dinosaur but I prefer the older style docks :(.

No you are right. I would probably opt on being cautious as well.

 

I do think if you hunt online you can find a compatability sheet.

Hello,


I have used the 40AN Lenovo Thunderbolt 3 Dock with 230W and a 135W power supplies plugged into it with a variety of ThinkPads, including a ThinkPad P72 (a predecessor to the P17 Gen 1), P50, and X1e Gen 3.  The trick to getting the dock to work with these ThinkPads that require higher wattage than USB-C provides is to use the ThinkPad Thunderbolt 3 Workstation Dock Split Cable (P/N 4X90U9061 or compatible) to connect the two devices to each other.  This ensures that the ThinkPad receives 320W of power via its SlimTip connector, while providing a Thunerbolt 3 connection over the USB-C connector.  And the dock gets its own separate power from the 135W power supply.

 

Regards,
