At home, I am using a Docking station (ThinkPad Mini Dock Series 3) which has a different power demand than the W520. The docking station works properly but does NOT charge the laptop. So, I plugged in a spare charger-plug directly into the laptop but it will not charge. My logical guess is that the docking power plug is over-riding the laptop plug. Is there a way around this so that I won't lose power while working from home using the docking station?

okay you have the old dock. There is no override for the charging port once it is docked. You are better off getting a 135 watts power adapter for your machine.

Can someone else confirm that 135 watts power adapter will supply necessary power to dock and charge laptop as discussed on this thread?
That's what I use. It has worked with my W510, a W520, and now my W530.

I'm not sure if this will help you, but the "Lenovo Thinkpad Mini Dock Plus Series 3/USB docking station I ordered a couple of weeks ago from B&HPhotoVideo in NYC (part LE433835U) came with the same 170 watt power supply as the one that came with my W530. The only difference I could find, while talking to a Lenovo Service rep, was the last letter in the part number, which indicated whether it came with the laptop,or the docking station. They are apparently identical, and interchangeable.
I went through lots of YouTube videos showing different docking stations that all looked very similar, but the one I wanted was the latest model, which is what B&H ships.
(I'm not trying to promote B&H, but I do trust them, and they also shipped me the latest model W530 without the noise issue that so many W530's have when used with the mini dock....)
(I've got more to say about the docking station, but I'll put that in my other thread, if I can still find it....)
