Dock Compatibility: Power



I have ThinkPad P51 (20HH) with 170 W power supply (20V / 8.5A). Is it ok to use 230W Workstation Dock with it (I'm worrying about ~25% power difference)?

Re: Dock Compatibility: Power

That is fine.  Both are 20V.  The laprop will only draw as much current as it needs.  You can use a 230-watt power supply with a machine that needs 20V  45-watts
