Important spec

Always choose SSD, not HDD. SSD make computer many time more fast.
Check RAM can upgrade later or not. Some thin laptop RAM is solder on board, cannot add more.
Screen: Full HD (1920x1080) at least. IPS screen have better color than TN.
Laptop for carry every day: choose light one (under 1.5kg) and good battery.
Check port: USB-C, HDMI, USB-A. Make sure it have port you need.

Check before you pay (especially second hand)

Open Task Manager (Ctrl + Shift + Esc) > Performance to see CPU, RAM, disk and GPU is same as seller say.
Press Windows + R, type dxdiag and press Enter to see full system and display info.
Open Device Manager > Display adapters. If you see yellow mark, VGA driver or VGA have problem.
Check BIOS date to guess how old computer is. Open PowerShell and type:

Get-CimInstance Win32_BIOS | Select-Object ReleaseDate

BIOS date can change after BIOS update, so also check sticker under laptop or on the box.

Check laptop battery health. Open Command Prompt and type:

powercfg /batteryreport

Open the report file and compare Design Capacity with Full Charge Capacity. If full charge is much less, battery is old.

Test every key on keyboard, touchpad, speaker, camera, WiFi and all USB port.
Look screen with white and black background to find dead pixel or bright spot.

After you buy

Ask about warranty and keep the receipt.
Make sure Windows is genuine and activated: Settings > System > Activation.
Remove program you don't need and create your own user account with strong password.
