A second hand laptop is sold in whatever condition the previous owner left it in. A refurbished laptop has been professionally inspected, repaired, data-wiped and tested before resale, and comes with a warranty. That is the core difference, and it changes everything about what you can expect from the purchase.
Both cost less than buying new, but the risks, protections and long-term value are very different. This guide compares the two side by side so you can decide which one makes sense for your situation.
| Factor | Second Hand | Refurbished |
|---|---|---|
| Tested before sale? | No. Sold as-is | Yes. Multi-point inspection (at CLS, 20 checks) |
| Faulty parts replaced? | No | Yes. Anything that fails testing is swapped |
| Data wiped? | Maybe. Often just a factory reset (recoverable) | Yes. Secure wipe to NIST 800-88 standards |
| BIOS unlocked? | Unknown. May carry a BIOS password or Computrace | Yes. BIOS cleared, tracking software removed |
| Operating system | Whatever was on it. May be expired or unlicensed | Fresh licensed Windows 11 Pro installed |
| Warranty | None (private seller) or 30-90 days (marketplace) | 6-12+ months from the refurbisher |
| Returns | Usually final sale | 30-day returns standard |
| Condition grading | Vague (“good condition”, seller photos) | Formal grades (A/B/C) with defined criteria |
| Price | Cheapest option (but highest risk) | 40-70% off new (lower risk, better value per dollar) |
| Where to buy | Facebook Marketplace, Gumtree, eBay (private) | Specialist retailer, OEM outlet, eBay Refurbished |
| ACL protection | Only if bought from a business. Private sales = no ACL | Yes. Full Australian Consumer Law guarantees |
A second hand laptop is a device that has been used by someone else and is now being resold, typically by a private individual. The key word is as-is. The seller is not a business, has not tested the device beyond turning it on, and makes no guarantees about how long it will keep working.
Common second hand sources in Australia:
A refurbished laptop is a pre-owned device that has gone through a professional restoration process: inspected, repaired where needed, data-wiped, graded and sold with a warranty. For a deeper look at grading, see our guide to what refurbished actually means.
Most refurbished laptops in Australia are ex-corporate lease returns. Businesses lease fleets of business-grade laptops (Dell Latitude, HP EliteBook, Lenovo ThinkPad) for 3-4 years, then return them at the end of the lease. These machines were maintained by IT departments and used at desks, not dropped or abused. A professional refurbisher then restores them to full working order.
A refurbished laptop typically costs $100-200 more than a comparable second hand listing. That premium pays for:
When you factor in the Windows licence alone, the effective price gap between second hand and refurbished narrows to almost nothing.
Here is what a typical Dell Latitude 5520 (11th Gen i5, 16GB RAM, 256GB SSD) costs from each channel:
| Channel | Typical price | Warranty | Windows licence | True cost (laptop + Windows) |
|---|---|---|---|---|
| Facebook Marketplace | $250-350 | None | Maybe (unverified) | $250-550 (if you need to buy Windows) |
| Gumtree | $280-380 | None | Maybe | $280-580 |
| Cash Converters | $350-450 | 90 days | Usually | $350-450 |
| Refurbished retailer (CLS) | $380-480 | 12 months | Yes (Win 11 Pro, genuine) | $380-480 |
The refurbished option is only $30-130 more than marketplace, but comes with 12 months of warranty, verified data destruction, a genuine Windows licence and 30-day returns. [OWNER TO CONFIRM: check current Latitude 5520 pricing on site before publish]
Second hand is not always the wrong choice. It can work if:
If none of those apply, refurbished is the safer choice every time.
This is one of the biggest differences between second hand and refurbished, and most buyers do not know about it.
This is why buying from a registered business matters. At Computer and Laptop Sales, every purchase is covered by the ACL, a 12-month warranty and a 30-day return policy.
Every laptop is 20-point tested, backed by a 12-month warranty and covered by a 30-day return policy. From $260.
A second hand laptop is sold as-is by the previous owner, with no testing, no repairs and no warranty. A refurbished laptop has been professionally inspected, repaired where needed, data-wiped and tested, then sold with a warranty (typically 12 months) and a return policy.
It depends on the source and your technical ability. A second hand laptop from someone you know can be a good deal. From a stranger on a marketplace, the risks are higher: no warranty, no verified data wipe, potential BIOS locks, and no Australian Consumer Law protection on private sales. For most buyers, a refurbished laptop offers better value per dollar spent.
The price premium (typically $100-200) covers professional testing, component replacement, secure data destruction, a licensed copy of Windows 11 Pro (retail value $200+), a 12-month warranty and 30-day returns. When you factor in the Windows licence alone, the effective gap is minimal.
No. A factory reset marks data as deleted but does not physically erase it. Data recovery tools can retrieve files, passwords and personal information from a factory-reset drive. Professional refurbishers use NIST 800-88 secure wipe protocols or replace the drive entirely.
From a private seller, no. From a business seller (Cash Converters, eBay business), you may get 30-90 days. From a specialist refurbisher like Computer and Laptop Sales, you get a full 12-month warranty including the battery.
A BIOS lock is a password set at the hardware level, often by the corporate IT department that originally managed the laptop. A locked BIOS can prevent you from booting, reinstalling the OS or changing settings. It cannot be removed without the original company’s cooperation or professional tools. Refurbished laptops from reputable sellers always have the BIOS unlocked before sale.
Only if you buy from a business. The ACL covers refurbished and second hand items purchased from registered businesses (retailers, eBay business sellers, Cash Converters). Private sales (Facebook Marketplace, Gumtree private listings) are not covered by the ACL.
Yes, when purchased from a reputable refurbisher. Business-grade refurbished laptops (Dell Latitude, HP EliteBook, Lenovo ThinkPad) are built for 5-7 years of daily use and are typically returned after 3-4 years. After professional testing and repair, they have years of reliable service left. At CLS, every laptop passes a 20-point inspection and ships with a 12-month warranty.
Five things: (1) warranty length, at least 12 months including battery; (2) return policy, at least 30 days; (3) data wipe method (NIST 800-88 or equivalent, not just a factory reset); (4) BIOS unlock confirmation; (5) a genuine Windows 11 Pro licence pre-installed.
From a specialist refurbished retailer with a physical presence, quality certifications and a track record. For a comparison of Australian retailers, see our guide to the best place to buy refurbished laptops in Australia.
