W5x0 dock compatibilitites

Hello Am I right in assuming that the connector on the bottom of a W500 looks different from that of a W510? I am not asking whether I can use a W520 or W510 in a W500 dock - that has been asked to death on the internet and the answer is always "No, because the power supply requirement is higher for...

Re: W520 requires 170W AC adapter

Since I had a bunch of power tips, I ended up doing this:

I might add that my PSU is a 150 W unit (noname brand, but still), so do not expect it to cause any problems.

Re: W520 requires 170W AC adapter

This is what I got from the W510: 0 ohm = 135 W 1000 ohm = 135 W 1500 ohm = 135 W 2000 ohm = 135 W 2500 ohm = - (empty watt line, but it says "charging") 3000 ohm = - (empty watt line, but it says "charging") 4000 ohm = - (empty watt line, but it says "charging") 6000 ohm = - (empty watt line, but i...

Re: W520 requires 170W AC adapter

Oh, hey - the W510 reports the PSU as 135 W with 0 ohm?!? I did the first list on my x61s. It apparently differs between computers! Note: The x61s uses the latest Lenovo Power Manager, so it cannot be a software thing. I suppose the BIOS tells the Power Manager the wattage and the x61s was never exp...

Re: W520 requires 170W AC adapter

Right. I am confused. I got myself an adjustable potentiometer and soldered it to a butchered power tip. Changed the resistance around a bit and looked at what Lenovo Power Manager said under the Battery tab. These are my findings: 0 ohm = 120 W 1500 ohm = 120 W 2000 ohm = 120 W 2500 ohm = 50 W 3000...

Re: W520 requires 170W AC adapter

Good point. It doesn't matter if the system believes it to be 135W or 170W.

I shall try it as soon as I get the time. Have to do some things first that require an unexperimented and undestroyed power tip. Check back in a few days.

Re: W520 requires 170W AC adapter

I measure 10.0 kOhm between the outer metal cylinder and the center pin on my 65W PSU, regardless of whether the power connector is plugged in or not. This would suggest that there is just a resistor between the center pin and earth, probably somewhere inside the tip. Lenovo Power Manager correctly ...

Re: W530 graphics performance

The NVS is a crippled Quadro intended for 2D and multi-monitor use. Some cheapskates outfit 3D CAD workstations with NVSes which is crazy. If you work with 3D such as Solidworks, ProE or Inventor than avoid NVS like the plague. If you only do Photoshop or AutoCAD or such though, I suppose you are fi...

Re: W520 requires 170W AC adapter

Hello I would very much like to solve this mystery of the PSU identification thing. Mostly because I am cheap, and I bought a third-party 150W PSU for a W510 and found out that it will only see it as a 90W. So I can either go purchase a new $150 Lenovo 135W PSU or I can muck about with these three $...
