HP Elite DragonFly G2 with a Lenovo dock

[JohnHarrIrl]

Hi all, hope I can some help on this. I have an Elite Dragonfly G2 and have connected it to a Lenovo Gen 2 (LDA-KP) docking Station.

The charging symbol comes up on my laptop but it does not seem to be providing enough power as I run out of charge when using it. Anyone any ideas?

The dock supplies 20v 4.5A, and is connected via a dedicated Thunderbolt device port.

Thanks for any help,

JH.

The specs of your machine is

It ONLY requires 65W charger, that means the Lenovo dock should have enough juice to charge your machine. The question mark here: Your machine has (2) USB USB 3.2 Gen 1 Type-C ports which are NOT Thunderbolt ports and the specs of your Lenovo Gen 2 (LDA-KP) dock is

Definitely they are NOT compatible. Please note: not all USB-C ports are the same. If you wish FULLY compatible, please use the following list

(Note: the compatible list is on the last few pages).

@Banhein Thanks so much for speedy reply. The 2 ports have lightning symbol on them, so presume they are Thunderbolt? On the spec sheet it looks like the left-hand-side USB-A is the charging port, but that seems to mean I would need 2 cables in order to use the Lenovo dock (1 x USB-A for power and second USB-C ) to use monitors etc?

Thanks again,

It can charge small devices such as phones, tablets ... You can't use it to charge your machine.

Guys small discrepancy in info provided by @Banhein

The 2 ports on the RHS are Thunderbolt, so question is still unanswered.

Anyone any ideas?

Thanks,

Which one ? All their specs show:

• The HP machine has (2) USB USB 3.2 Gen 1 Type-C ports which are not Thunderbolt
• The Lenovo dock does not mention Thunderbolt at all

I would NEVER use cross vendors for expensive accessories

HP Elite Dragonfly Notebook PC G2 - Customizable - as you can see the Gen 2 has Thunderbolt.

@JohnHarrIrl 

Ok. I did say Leveno dock and your machine are not compatible and gave you a list of available docks for your machine. I also said I would NOT but cross vendors expensive accessories because they USE their standards.

No worries @BanHeim thank you for trying to help. Much appreciated.

Sorry, but in case this may help others, and not misguide them, I have to disagree and confirm HP have said the two ports, on the rhs ARE Thunderbolt, but agreed best to use a HP docking station.
