The Refurbished Laptop Checklist: 7 Things to Inspect Before Buying
Lappy Square Tech Team•12 October 2026
Refurbished laptops have become one of the smartest tech purchases for students, developers, and small businesses in India. In this comprehensive guide, our lead diagnostic engineer outlines the 7 non-negotiable checks to perform:
1. Battery Cycle Count & Health: Check wear level using BatteryInfoView or macOS System Report. Ensure health is above 80%.
2. Thermal Stress Testing: Run Cinebench or Prime95 for 10 minutes to verify fans and heatsinks.
3. Display Backlight & Dead Pixels: Run a full-screen white and black image test.
4. Keyboard & Key Travel: Test every function key and spacebar rebound.
5. All I/O Ports & Thunderbolt Charging.
6. Genuine Operating System License.
7. Written Warranty terms and GST Invoice.
At Lappy Square, all 7 checks (and 38 more) are performed before any laptop enters our catalogue!
