Five minutes that save you a headache:
- Windows activated: Settings › System › Activation.
- Processor, memory and drive as in the listing: Windows shows them in Settings › System.
- No password at startup, before Windows: a password the seller can’t remove locks the PC.
- Battery: in Command Prompt, type powercfg /batteryreport. The report compares the original capacity (Design capacity) with today’s (Full charge capacity).
- Screen, keyboard, ports and charging, then a heavy app for a few minutes to listen to the fans.
