What is the actual depth of the E6410

Could somebody tell me (by measuring), what is the actual physical depth of the E6410?

I visited a local university bookstore yesterday and saw they had both Lenovo and Dell business models on display. I couldn't resist comparing the sizes by placing laptops on top of each other

I was quite surprised to see the E6410 and T510 had near identical depths (front to back). The batteries were removed in these display models, so that does not include the battery.

Looking at the specs on notebookcheck, here is the reported depths.

E6410: 238mm
T510: 279mm

According to the specs, the E6410 is 4cm smaller. But this was not what I saw yesterday. Does the E6410 measurements include the silver block that protrudes from the back? Does the T510 measurement include the bigger battery that sticks out the back?

What's going on? Did I just make a mistake when I lined up the laptops on top of each other yesterday?

 

The E6410 depth spec is probably for the 6-cell battery. The 9-cell sticks out the back a bit.

Also the E6410 is 16:10; the T510 is 16:9, which means that the T510 has a wider aspect ratio than the E6410. That probably makes up for the height difference.
