Before Buying a Used PC or Laptop, Check These 4 Things First! 🖥️⚡
Thinking of buying a used PC or laptop? Don’t spend your money until you’ve checked these important things!
1. Check the Display
Open Notepad and maximize it to full screen. Look carefully for any dead pixels, bright spots, lines, or display defects. If you notice dots that don’t disappear, the screen may have issues.
2. Check the Hard Drive Health
Open Microsoft Store, search for CrystalDiskInfo, and install it.
Launch the app to view the drive’s health status. If the drive health is below 70%, you may want to avoid that system or factor in the cost of a replacement drive.
3. Test CPU and GPU Performance
Press Ctrl + Shift + Esc to open Task Manager, then go to the Performance tab.
Run a demanding application or benchmark and monitor CPU and GPU usage, temperatures, and system stability. High usage alone is normal during heavy workloads, but crashes, overheating, or severe throttling are warning signs.
4. Check Battery Health
Open Command Prompt and type:
powercfg /batteryreport
Press Enter.
Windows will generate a battery report and show its location. Open the report in your browser and compare Full Charge Capacity to Design Capacity. If the full charge capacity is less than half of the design capacity, the battery may need replacement.
These quick checks can save you from buying a PC with hidden problems! 💻✅
