Used laptop khareedte waqt sirf body aur price dekhna kaafi nahi hota. Laptop testing se aap performance, battery, display, storage aur ports ki asal condition samajh sakte hain. Is guide mein RAMAY Computers aapko ek practical step-by-step laptop testing checklist de raha hai.
1. Exterior, hinges aur ports check karein
Laptop ko band aur khol kar dekhein. Cracks, dents, missing screws, loose hinges aur bent body note karein. Har USB, HDMI, audio jack, LAN port, SD card slot aur charging port ko test karein. Charger lagane par charging stable honi chahiye.
2. Display aur keyboard test karein
Screen par white, black aur red/green/blue backgrounds chala kar dead pixels, bright spots, lines aur uneven backlight check karein. Brightness ko minimum se maximum tak change karein. Har keyboard key, touchpad, left/right click aur keyboard backlight ko test karein.
3. Battery aur charger ki health
Battery ko 15 se 20 minutes unplugged use karke dekhein. Agar percentage bohat tezi se girti hai, battery weak ho sakti hai. Windows mein Command Prompt khol kar powercfg /batteryreport run karein, phir Design Capacity aur Full Charge Capacity compare karein. Charger original wattage ka ho aur cable garam ya damaged na ho.
4. CPU, RAM aur storage test
Task Manager ke Performance tab mein CPU model, RAM amount aur speed verify karein. SSD health ke liye CrystalDiskInfo jaisa tool use karein. Health status Good hona chahiye aur abnormal warning, high temperature ya repeated errors nahi honay chahiye. Storage capacity ko BIOS aur Windows dono mein cross-check karein.
5. Wi-Fi, webcam, speakers aur microphone
Wi-Fi se connect ho kar ek speed test karein. Webcam app se camera, microphone recording aur speakers ko check karein. Bluetooth device connect karke dekhein. Sleep, wake, restart aur shutdown bhi test karein taa-ke driver ya power issue samne aa sake.
6. Stress test aur final report
10 se 15 minutes ka light stress test ya high-quality video playback chala kar temperature, fan noise, throttling aur sudden shutdown observe karein. Laptop ko stable rehna chahiye. Test ke baad ek short report banayein: model, serial number, CPU, RAM, SSD, battery health, screen condition, included charger aur warranty status.
Quick buying checklist
- Model aur serial number invoice se match karein.
- RAM aur SSD ki capacity verify karein.
- Screen, keyboard, touchpad aur ports individually test karein.
- Battery report aur SSD health screenshot save karein.
- Charger, warranty aur return policy written form mein lein.
Final advice
Used laptop lene se pehle kam az kam 30 minutes testing ke liye rakhein. Agar seller testing se mana kare, battery ya SSD health hide kare, ya specification invoice se match na kare, to purchase delay karein.
