How to look up specs for newer style machine type numbers?

[serpico]

On Lenovo's site, I inputted a serial number (of a T431s someone is selling), and the site returned this machine type info:
"Machine Type Model 20AAS00900".

But when I try searching Lenovo for that machine type, nothing comes up.

You need to go here: http://pcsupport.lenovo.com/us/en/partslookup and put in the S/N
You may need to use Internet Explorer for that, because of Lenovo's abominable website mentality.

Thanks. The parts list that shows up is nowhere near as convenient to skim through as http://tp.krelay.de/index.php for the older 7-digit machine types.

Is the "Innolux 14.0HD+ AG" panel 1600x900 resolution?
