Keep Windows awake.
Keep CPU overhead near zero.

StayGreen is the low-overhead keep-awake utility for professionals dealing with managed laptops, aggressive sleep policies, and presence-sensitive workflows.

Prevent sleep and work with Windows power management rather than around it — no fake mouse movement, no polling loop. StayGreen holds a documented Windows power request, then adds guardrails that pause on battery, on Battery Saver, and when the lid closes with no display attached.

Pay once. Own it forever.

The old workflow

Mouse jigglers, fake input, and polling loops are the wrong abstraction.

Most keep-awake tools simulate activity, chew through battery, or trip corporate controls because they work around Windows instead of with it. That leaves technical buyers choosing between unreliable hacks and annoying sleep behavior.

The StayGreen workflow

Request the awake state directly. Add guardrails where it matters.

StayGreen holds a Windows power request — the documented mechanism a media player uses during playback — so the machine stays awake without fake mouse movement or a polling loop. Then it layers in laptop-aware safety controls: charger state, Battery Saver, and a lid rule that checks whether a display is actually attached.

Core Capabilities

Built for managed Windows machines, not novelty gadget workflows.

Effectively Zero CPU Overhead

No polling timer. No fake cursor drift. No synthetic input loop. StayGreen uses Windows power-state signaling so the app can keep the system awake while typically reading around 0.0% CPU at idle in Task Manager.

Hardware Interlock

The keep-awake state auto-pauses when the charger is unplugged, when Battery Saver switches on, or when the lid closes with no external display attached — so a long session does not quietly drain a battery. Each pause resumes on its own when the condition clears.

Clamshell Mode Support

StayGreen automatically detects external-monitor setups and behaves correctly for docked or clamshell workflows where the internal panel should not dictate awake behavior.

Per-App Targeting

Scope the behavior to specific executables like ms-teams.exe so the keep-awake state only engages when the workflow actually needs it. That means less blanket override, more intentional control.

Engineering Proof

~0.0% CPU at idle · < 8 MB RAM

Direct Win32 signaling instead of background churn.

StayGreen asks Windows to stay awake by holding a power request—no fake mouse movement, no periodic wake pings, and no background loop burning cycles just to pretend the user is active.

For technical buyers, the operating system does the work while StayGreen sets the appropriate flags and gets out of the way. In idle tests, Task Manager reports roughly 0.0% CPU usage with a memory profile under 8 MB for the keep-awake path.

No polling loop required to maintain state
No synthetic input events to trigger EDR or policy suspicion
Cleaner fit for enterprise-managed workstations with restrictive sleep defaults

Product Interface

The StayGreen window showing the keep-awake switch, timed session presets, and per-app rule controls

A control panel built for intentional power-state overrides.

The StayGreen interface keeps the important decisions obvious: when to override sleep, how long to hold the state, and which app should trigger it. No command-line dance. No clutter disguised as enterprise UX.

Timed session: 15, 30, 60, or 120-minute presets, or a custom length, for meetings, uploads, renders, or overnight monitoring — so the hold releases itself instead of staying on indefinitely.

Per-app targeting UI: Bind the behavior to foreground apps so the override becomes part of the workflow, not a blanket machine-wide hack.

Guardrail-first defaults: Laptop-aware conditions stay visible so the user understands when StayGreen will step back automatically.
