I'm pretty sure I had to resolder only two wires. Even if there was a third, that should not make a difference, since the 90W adapter is accepted fine. The difference must be in the plug. Measuring with a voltmeter reveals that the outer surface is the minus, the inner the plus pole. They are 20V on...

Typical Apple paternalism. Hold on, it's not Apple but Lenovo who is paternalistic? Well, it doesn't surprise me anymore; each new ThinkPad I got since 2001 had some stupid or cheap new flaw that wasn't there in the previous generation. They also don't offer the adapter cable as a spare part, so if ...

If it's not the notches that push something that then tells the W520 it's the right AC (I agree that seems unlikely), then the 135W adapter may also have that invisible little something in the tip (I wouldn't think it's in the middle of the cable), and may work just as fine. My assumption is that th...

Very easy: I cut the one cable, took the two cables inside, and soldered them to the two cables from the other cable. Just make sure +/- matches. Voilà. The 90W adapter does it fine so far, 120W would surely work, too, even under higher loads. I don't know if the trick would work by taking the conne...

Will do. But don't put your hopes high. I'm not a heavy gamer who, at the same time, formats his HD, writes DVDs, and uses the docking station and all ports.

I found a pretty simple solution. I unsoldered the cable from my 170W power adapter and soldered it to my 90W adapter. Voilà! The W520 runs and charges at the same time. The adapter does get slightly warm sometimes, but so far I never managed to get it warmer than when it ran with my T60p. I just wi...

3 screens WQXGA on Quadro 1000M
1 screen 1080p on Intel

Sounds possible?

That sounds cool. Are you connecting the monitors on the DVI and DP port respectively? My bad for the misleading info., as according to Lenovo, the DVI port is not DVI-D one. If it is, then it rocks :D Unfortunately, you were right with regards the DVI ports. They are both only Single-DVI; even the...

I got my W520, dock, DP-DL-DVI adapters, tried, and -- surprise -- I could run both 2560*1600 screens in full resolution FROM THE DOCK! The result is a sweet 3200*2560 desktop, plus the TP display. This is different from what Lenovo and trustworthy people (in this forum) deemed possible. I didn't ne...

1. Impossible, only 1 DVI and 1 DP port can be used simultaneously, and DVI on MDP3 supports up to 1920*1200 2. No difference 3. T520 with Nvidia card works the same 1. Good point. Looks like I have to stick with two 2560*1600 screens as long as I don't use a separate ViDock. Curses on Lenovo for m...

One more twist you may find interesting. I'm not a gamer, but I find a high resolution crucial for my work with html, pdf, and doc. After waiting 5 years to replace my T61, I think I’ll finally go for the W520, in spite of the worse horizontal display resolution, sigh (1080 px vs. 1200). Currently, ...
