February 2011
Series
EDGE

The Edge E31 combines the compact 13.3-inch Edge form with low-voltage Intel processing. The Chinese 025027C configuration here uses Pentium U5400 and Windows 7 Home Basic.

Historical context

The Pentium U5400 and absence of an internal optical drive favoured a compact, lower-power notebook. This Chinese configuration paired a 13.3-inch HD panel with Windows 7 Home Basic rather than workstation graphics.

Date sources & variant notes
2011 · ThinkPad E31 (025027C, China)

Regional SKU introduction · Sina explicitly gives February 2011 as the market-introduction month for Chinese SKU 025027C. This dates that regional configuration, not the first E31 worldwide: Lenovo already names E31 in a September 2010 driver document, which is not used as a laptop launch date.
