Question: Lenovo laptop with Intel Core i5 processor, no WiFi (only Ethernet), around 2011, with a 500GB hard disk—what series is it likely from?

Answer:

Your description points strongly to a Lenovo ThinkPad series laptop from around 2010–2012 (Sandy Bridge / 2nd generation Intel Core i5 era), most likely a business-oriented model where WiFi was sometimes optional, disabled, removed, or failed over time. Consumer models (like IdeaPad) from that period almost always included built-in WiFi by default.

Most Likely Series & Models

ThinkPad T series (very common match):
- ThinkPad T410 / T420 (2010–2011)
  - Often shipped with Intel Core i5-520M / i5-540M / i5-2520M etc.
  - Standard configs included 250–500GB HDD (5400 or 7200 rpm).
  - Gigabit Ethernet was always present; WiFi (Intel or Atheros) was standard but could be absent in rare corporate “no wireless” orders, or the card could have been removed/disabled.
  - 14.1” screen, durable build, very popular in 2011.
ThinkPad L series (budget business line, good fit):
- ThinkPad L420 / L520 (2011 refresh)
  - Core i5 options (e.g., i5-2520M, i5-2540M).
  - Up to 500GB 7200rpm HDD commonly offered.
  - Ethernet standard; WiFi was optional/configurable (some enterprise versions skipped the wireless card to cut costs or for security policies).
ThinkPad Edge / E series (entry-level business, 2011):
- ThinkPad Edge E420 / E520
  - Core i5-2520M etc.
  - 500GB HDD option listed in specs.
  - Similar: Ethernet built-in, WiFi often included but could be missing in specific SKUs.
Less likely but possible:
- IdeaPad consumer models (e.g., Y560, Z570, V470, Z370) almost always had WiFi built-in (Intel Centrino or similar) in 2011 configs with i5 and 500GB HDD. “No WiFi” would be unusual unless the card failed or was removed later.

Why “No WiFi, Only Ethernet”?

In 2011 business laptops (especially ThinkPads sold to companies/schools/governments), WiFi modules were sometimes not installed for security reasons (e.g., prevent unauthorized wireless access) or cost savings.
The WiFi card could have failed/been disconnected over time (common on 10+ year old machines).
BIOS might have it disabled.
Ethernet (RJ-45 Gigabit) was mandatory/standard on all these models.

If it’s a 14-inch screen with a red TrackPoint in the middle of the keyboard, it’s almost certainly a ThinkPad T410/T420 or L420. These were extremely common around 2011 with exactly those specs (i5, 500GB HDD, Ethernet focus).

To confirm: Boot into BIOS (F1 on ThinkPad) and check if a wireless card slot shows as empty, or look at the bottom label for the exact model number (e.g., starts with 4236-xxx for T420).
