Mouse Jiggler vs changing your sleep settings
The simplest fix for "my computer keeps sleeping" is to change the sleep timeout in system settings. Here is why that is not always the better choice.
Short answer
- Changing sleep settings is free and built-in, but it is a global, persistent change that is easy to forget to undo.
- A mouse jiggler is session-based: it only runs when you start it, for as long as you need it, and does not touch your system configuration.
- If you only need to block sleep once for one task, changing settings works fine. If you need this repeatedly across meetings, downloads, and demos, a keep-awake utility is less error-prone.
- Managed devices may restrict changing power settings entirely, which makes a user-level utility the only practical option.
Comparison
| Capability | Mouse Jiggler | Changing sleep settings |
|---|---|---|
| Scope of change | Session-based, runs only when started | Global system setting until manually reverted |
| Works on managed/locked-down devices | Yes, runs as a normal user app | Often restricted by IT policy |
| Setup time per session | Start the app | Navigate system settings menus each time |
| Cost | One-time $9.99 | Free |
| Affects Teams/Slack presence | Yes, cursor movement keeps activity visible | No, sleep settings alone do not simulate input |
The simple fix and its catch
Raising your sleep timeout in system settings costs nothing and takes a minute. The catch is that it is a global change: once set, it applies to every session, not just the one you needed it for, until you remember to change it back.
When changing settings is enough
If you rarely need to block sleep, and you are comfortable remembering to revert the setting afterward, changing it directly is a fine, free option.
When a keep-awake tool fits better
If you need this regularly — for meetings, downloads, demos, or presence status — a session-based tool removes the step of remembering to revert anything, and it also generates the cursor activity that sleep settings alone do not provide.
Managed devices
On a work or school device where power settings are locked down by IT policy, a user-level keep-awake utility may be the only option available to you at all. Confirm with your organization that this is permitted before relying on it.
FAQ
Is it bad to just turn off sleep permanently?
It is not unsafe, but it means your device stays awake and consumes power even when you are not using it, and you have to remember you made the change.
Will a mouse jiggler work if my IT department restricts power settings?
In most cases yes, since it runs as a normal user application rather than changing system-level power configuration, but confirm this is allowed on your managed device.
Does this affect battery life?
Keeping a laptop awake longer than it otherwise would be does use more power than letting it sleep, whichever method you use to do it.
