Certified Refurbished Lenovo ThinkPad T420 Laptop
The Certified Refurbished Lenovo ThinkPad T420 features an Intel Core i5-2450M processor running at 2.50 GHz, 4GB DDR3 RAM, 320GB HDD storage, and a 14-inch display with 1366x768 resolution. This 2nd generation Intel processor offers dual-core performance with turbo speeds up to 3.10 GHz, which means you can handle multiple applications simultaneously—browsing with 10+ tabs, running Microsoft Office documents, and video calls without noticeable slowdowns. While this 2011-era ThinkPad won't match modern ultrabooks, it delivers dependable everyday computing for budget-conscious users who need proven reliability over cutting-edge specs.
This unit comes without an operating system installed, giving you the flexibility to install Windows, Linux, or your preferred OS. The included DVD/RW drive—increasingly rare in modern laptops—proves useful for installing legacy software, playing physical media, or backing up data to discs.
Ideal For
This professionally restored laptop suits:
- Students managing coursework - Writing essays in Word, researching with multiple browser tabs, and attending Zoom lectures simultaneously without breaking the budget
- Home office workers handling daily tasks - Email management, spreadsheets, web browsing, and video conferencing for users who don't need intensive graphics or processor power
- Budget-conscious users seeking proven reliability - ThinkPad's legendary build quality and keyboard at refurbished pricing, perfect for basic computing needs
- Linux enthusiasts and tinkerers - No pre-installed OS means freedom to install your preferred operating system and customise the experience
Common Questions
Can it handle video calls while multitasking?
Yes, the Core i5-2450M's dual-core processor with 4GB RAM manages Zoom or Teams calls alongside email and light document work. You'll want to close unnecessary background programmes during calls for optimal performance, but typical office multitasking works smoothly.
How does the 320GB HDD compare to modern SSDs?
The traditional hard drive boots Windows in approximately 60-90 seconds compared to 10-15 seconds for SSDs. File transfers and application loading take longer, though the 320GB capacity offers decent storage space. Many users upgrade to an aftermarket SSD for significantly improved responsiveness.
Is this suitable for modern software in 2026?
For lightweight applications like web browsing, office software, and media playback, absolutely. However, resource-intensive programmes like video editing suites, modern gaming, or heavy multitasking with 20+ browser tabs will push this system beyond comfortable performance limits.

Performance & Real-World Use
Our technicians routinely test hundreds of 2nd generation Intel laptops, and the i5-2450M consistently delivers for typical 2026 office tasks. During testing, this configuration handles document editing, web browsing with 8-10 tabs, and streaming 1080p video without stuttering. The processor performs comparably to Intel's slightly older i5-2430M, though both fall behind modern processors in raw speed.
The 320GB hard drive represents the main performance bottleneck—boot times exceed one minute, and large file transfers feel sluggish compared to SSD-equipped machines. However, the mechanical drive offers upgrade potential, and many users replace it with an aftermarket SSD for dramatically improved responsiveness at minimal cost.
Operating System: Not Included
Pros: Complete flexibility to install Windows 10, Windows 11 (if TPM requirements are met), Linux distributions, or other operating systems matching your specific needs and budget. Cons: Requires OS purchase and installation knowledge, which may present a barrier for less technical users expecting ready-to-use functionality.
