I am asking because reviews report quite different display quality.
The NotebookCHECK review of the T520 provides a positive assessment:
Source:Information
Gossen Mavo-Monitor
Maximum: 231 cd/m²
Average: 193.8 cd/m²
Brightness Distribution: 70 %
Black: 0.33 cd/m²
Contrast: 670:1

The NotebookCHECK review of the W520 comes also to a positive conclusion:
Source:Information
Gossen Mavo-Monitor
Maximum: 236 cd/m²
Average: 217.9 cd/m²
Brightness Distribution: 87 %
Center on Battery: 236 cd/m²
Black: 0.36 cd/m²
Contrast: 656:1

However, the German Notebookjournal.de review of the T520 display reports a completely different contrast:

Contrast: 158:1

Apparently, Lenovo is using two different HD+ panels for the L520 / T520 / W520.
See the FRU numbers:
15.6-inch LED-backlight LCD Service Parts - ThinkPad T520, T520i

&
15.6 inch (1600 x 900) HD+ LED-backlight LCD service parts - ThinkPad L420 and L520

I would also like to know whether you have experienced any issues with the fan at your ThinkPad machine and how you have solved it.
Do you know any other detailed reviews of the 15.6" ThinkPads?
Thanks!
