Smart Strategies for Purchasing a Second-Hand Laptop

Chapter 1: Understanding the Benefits of Used Laptops
Many people assume that programmers always buy the latest gadgets. However, I prefer to avoid splurging on brand-new laptops or computers. This choice stems from two primary motivations: my desire to save money and my commitment to sustainability. By keeping my expenses low, I can invest in what I genuinely need. Given the increasing demands of programming tools, finding the right balance can be a challenge, but it's one that I enjoy.
Instead of spending around $4,000 on a brand-new Apple laptop, I can allocate those funds towards other necessities or save for future needs. A practical approach is to seek out refurbished laptops or purchase directly from previous owners or pawn shops. This not only reduces waste through reuse but also allows me to find a laptop that suits my requirements for as little as $200. That's right—$200! This decision saves me a whopping $3,800 compared to the cost of the latest Apple model. Typically, such laptops can serve well for two to three years before they can be resold for continued use.
How to Evaluate Laptop Options
When it comes to selecting a used laptop, the process becomes simpler when you stick to a budget. Websites like NotebookCheck are invaluable for reading reviews and assessing performance metrics. While I utilize my own camera, headphones, monitor, keyboard, and mouse, my primary concern for a laptop is its performance.
To gauge this, I focus on three key performance indicators:
- PCMark 7 Score
- Cinebench R15 CPU Single 64Bit
- CrystalDiskMark 3.0 Write 4k
The PCMark score provides an overall benchmark for performance. In my case, software like Windows 10, Spotify, Chrome, XSplit, Google Meet, and Slack demand significant processing power, prompting my search for a new device to enhance my experience.
Cinebench measures the single-core performance, which is particularly useful when rendering tasks in Blender. While not critical, as I often batch render, it’s beneficial to have a good score. The CrystalDiskMark score evaluates disk performance, specifically the speed of writing data, which can often be a bottleneck in overall system performance.
Upgrading Disk and Memory
Once I ensure the laptop meets my performance needs and fits within my budget, I can consider upgrades. Two important components to focus on are the disk and memory.
A solid-state drive (SSD) is essential for optimal performance. Many laptops come with SSDs already installed, but if not, it's often possible to replace an HDD with an SSD. This upgrade significantly boosts performance. When evaluating an SSD, it’s crucial to check user-reported lifespan and 4k write speed to ensure reliability.
Data loss can occur with hard drives, particularly SSDs, making it vital to have a solid backup strategy. I recommend implementing an automated daily backup and conducting monthly checks to ensure data integrity. If you're considering a new disk purchase, I advise buying new hardware, as disks deteriorate over time and can be transferred to future laptops.
For my work, 16GB of memory is typically sufficient. I often only utilize a fraction of that, so I can redistribute memory from an older laptop I'm phasing out. However, be mindful of soldered memory, as it cannot be upgraded if it's integrated into the motherboard.
While upgrading the SSD and memory can be postponed, it's wise to check if the disk is replaceable for future flexibility.
Potential Risks of Buying Used Laptops
Purchasing a second-hand laptop does come with its risks. The primary concerns are related to the CPU, motherboard, and screen. If the CPU or motherboard malfunctions, there are straightforward fixes, such as cleaning and applying new thermal paste. However, more severe issues can be challenging to resolve, highlighting the importance of thorough checks before buying.
Screens can also be costly to replace, so ensure they are in good condition prior to purchase.
Conclusion
Here’s a summary of essential steps to take before purchasing a used laptop:
- Ensure the PCMark 7 Score, Cinebench R15 CPU Single 64Bit, and CrystalDiskMark 3.0 Write 4k scores are satisfactory.
- Verify the laptop functions properly and the CPU is in good condition.
- Invest in a new SSD if necessary.
- Purchase additional memory if required.
- Enjoy improved performance while saving $3,800!
Even if your initial purchase doesn't meet expectations, you can resell it without losing significant money.
