Tips for Choosing a Good Quality Used Computer
Here are some tips and experiences when choosing to buy a used laptop to help you decide whether to buy a used computer or not.
Inspect the Entire Exterior of the Computer
Before deciding to purchase a used laptop, thoroughly inspect the overall exterior, checking if the hinges are secure. Additionally, examine the edges for any signs of peeling or extensive scratches to ensure the quality matches the amount you are investing.

Check Information and Specifications of the Computer
Checking the information and specifications of the computer is a crucial factor to help you verify if the machine's parameters match the supplier's introduction. This aids in making an informed decision on the appropriate Windows version. For Windows computers, use USB BOOT or CrystalDiskinfo software to check if the hard drive has any issues. Access the BIOS to examine the machine's specifications. Additionally, pay attention to the laptop's startup time to gauge the hard drive's accessibility.

Inspect Around the Screen
When purchasing a used computer, carefully inspect the area around the screen. Rotate the machine at various angles to check if the display is clear and free from scratches or vibrations during use. If the screen is heavily scratched, carefully consider whether to buy the used computer or not.
Additionally, some laptops may have dead pixels on the screen, appearing as bright spots or small blemishes that hinder content display. To check for dead pixels on the screen, follow these steps:
- Step 1: Right-click on the screen > Select Personalize > Choose Background
- Step 2: When the Background window appears > Select Solid Color
- Step 3: Choose a color of your choice and observe if there are any bright spots along the screen edges.

Examine the Product's Details
In addition to checking the screen, scrutinize the details of the computer. Test typing in Word and use Keyboard Test to check if the keyboard is functional.
Furthermore, assess the sensitivity of the mouse and touchpad by dragging, clicking, and double-clicking. Checking the microphone, speakers, webcam, and fingerprint sensor is essential to ensure the quality of the used computer, avoiding additional costs and repair time.

Reevaluate the Connectivity Ports, Wifi, and Bluetooth of the Computer
Rechecking the connectivity ports, Wifi, and Bluetooth will provide you with more confidence before deciding whether to buy a used computer. Verify the connectivity ports by plugging in corresponding devices. If the laptop doesn't recognize the connections, it indicates a potential issue.
For Wifi, assess the machine's signal strength by moving it to different locations. If the computer has poor Wifi reception, you may want to reconsider buying the used computer.

Confirm the Warranty Information of the Computer
A used computer that still carries the manufacturer's warranty provides an added layer of reassurance for your purchase. Typically, business dealers offer testing support for a period ranging from 7 days to 3 months. Therefore, don't forget to confirm the warranty information to receive assistance when needed!
