💸 Price Check
Before you buy, ask the seller:
-
How old is the computer?
-
What was its original retail price?
Computers depreciate quickly, especially models more than 3–4 years old. Compare similar listings on DoneDeal and other sites to get a sense of current second-hand value.
Keep in mind that technology evolves fast — newer models tend to offer longer software support, better battery life, and faster performance.
⚙️ Performance Basics
When you view the computer in person, ask the seller to power it on and show that it’s working properly.
Check that it:
-
Boots quickly (within a minute)
-
Opens apps without freezing
-
Connects to WiFi
-
Plays video and audio clearly
If the machine is in good working order, most sellers will happily demonstrate its capabilities.
🧠 Memory (RAM)
RAM affects how many programs you can run smoothly at once.
-
8GB RAM → suitable for web browsing, office tasks, and light use.
-
16GB RAM → ideal for multitasking, streaming, and most everyday users.
-
32GB+ RAM → best for gaming, media editing, or professional software.
You can usually check this in the System Settings or About This Mac/PC section.
⚡ Storage (SSD vs HDD)
Storage speed makes a big difference to performance.
-
SSD (Solid-State Drive): Much faster and quieter than older HDDs. Look for at least 256GB SSD for general use.
-
HDD (Hard Drive): Slower but cheaper; okay for bulk file storage only.
If possible, go for an SSD-based system — it’ll boot up in seconds.
🧩 Processor (CPU)
The processor is your computer’s brain.
Modern processors include:
-
Intel: Core i5 / i7 / i9 (newer models may say “13th Gen” or “14th Gen”)
-
AMD: Ryzen 5 / Ryzen 7 / Ryzen 9
-
Apple: M1, M2, M3 chips (found in recent MacBooks and iMacs)
For general use, a mid-range i5 or Ryzen 5 is plenty. Gamers and creators should aim higher.
🎮 Graphics (GPU)
-
Integrated graphics (e.g. Intel Iris Xe, AMD Radeon Vega, Apple M-series) handle browsing, video, and casual gaming.
-
Dedicated graphics cards (e.g. Nvidia GeForce RTX or AMD Radeon RX) are ideal for gaming, 3D design, and video editing.
If gaming or creative work matters to you, confirm the model of the graphics card before you buy.
💽 Software & Operating Systems
Check which operating system is installed:
-
Windows 10 or 11 (most common for PCs)
-
macOS (for Apple computers)
-
ChromeOS (on Chromebooks)
-
Linux (popular with tech-savvy users)
Make sure it’s genuine and activated, with any login details or passwords cleared before purchase.
🔌 Ports & Connectivity
Modern computers often replace older ports with newer ones.
Check for:
-
USB-C (common on newer laptops)
-
HDMI or DisplayPort (for monitors or TVs)
-
Audio jack (some models no longer include one)
-
SD card slot (optional but handy)
Also check that WiFi and Bluetooth are working. Ideally, look for WiFi 6 and Bluetooth 5.
🔋 Battery & Power
If buying a laptop, test the battery:
-
Unplug it and see how long it lasts on battery power.
-
In Windows or macOS, check battery health or cycle count (fewer than 500 cycles is ideal).
If it dies quickly, you may need a replacement battery — factor that into the price.
💡 Screen & Display
-
Size: 13”–15” laptops balance portability and comfort.
-
Resolution: Aim for Full HD (1920×1080) or higher.
-
Brightness & Colour: Check for dead pixels, discoloration, or flickering.
If you use the computer for more than a few hours daily, a larger or higher-resolution screen is worth the investment.
🎥 Webcam, Mic & Speakers
Most modern laptops have built-in webcams and microphones.
-
Test video and sound quality.
-
Check that privacy shutters or camera switches (if present) work correctly.
-
If it doesn’t have a webcam, you can easily buy an external one.
📦 Warranty, Returns & Proof of Purchase
Always ask:
-
Is there still a manufacturer’s warranty or extended cover?
-
Can you get a receipt or proof of purchase?
Some refurbished sellers provide a 6–12 month warranty — this is a good sign of reliability.
🔄 Upgrades & Accessories
You might want to upgrade later — check that the computer allows it.
-
Can you add more RAM or storage?
-
Does it support external monitors or docks?
If you’re missing accessories (keyboard, mouse, charger, etc.), they’re easy to find on DoneDeal’s Wanted or Computers sections.
