INFORMED SHOPPING
What should you consider when choosing a used computer?
To avoid surprises when buying or selling a used computer, the factory condition of the hardware should be carefully examined.
Processor Generation
Don't be fooled by the "i7" name; the processor's generation and core count determine its performance.
RAM Capacity
Current operating systems and programs require at least 16 GB of DDR4/DDR5 memory.
SSD Health (SMART)
Mechanical hard drives or SSDs that have reached the end of their lifespan can lock up the system; NVMe drives should be preferred.
Graphics Card History
Chips that have been mined or baked should be avoided; VRAM stability should be tested.
Screen Panel
Dead pixels, light leakage, and vertical lines should be checked; the original panel should be verified.
Battery Status
Used laptops should have a non-swollen battery and be able to work unplugged for at least 1.5-2 hours.
Frames and Hinges
The hinges should be rigid and the screw holes should not be broken; the body should not flex when the lid is opened.
Ports and Inputs
Ensure that the USB, Type-C, HDMI, and audio inputs are functioning correctly.
