Screen capture on a Windows laptop

Battery and performance

• Screen recording is the heaviest capture task — prefer hardware encoding where the tool supports it.
• Background upload tools keep the network radio active; disable automatic upload when on battery.
• Lightweight tools such as Greenshot and Lightshot add almost no idle overhead.

Troubleshooting when the screenshot does not work

• Nothing happens on Print Screen: on a Windows laptop the key may be shared with a function key. Try Fn + Print Screen or Fn + Windows + Print Screen.
• Windows + Shift + S does nothing: check Settings > Accessibility > Keyboard, and make sure the Snipping Tool app is installed and updated from the Microsoft Store.
• The screen does not dim: another application may have taken the hotkey. Close capture tools running in the notification area and try again.
• Screenshots are black: this usually means hardware-protected content, such as a DRM video player. Capture the window with a different tool or disable hardware acceleration in that application.
• The file never appears: Windows + Print Screen writes to Pictures\Screenshots. If OneDrive is managing your Pictures folder, look inside OneDrive \ Pictures \ Screenshots.
