Caffeine for Teams: Does It Actually Keep You Active?
It's one of the most repeated bits of remote-work advice: install Caffeine and your Microsoft Teams will stay green. Caffeine is a great little app — but it solves a different problem than the one you actually have. Because Teams is so heavily Windows, you'll also hear the same tip framed as "just stop Windows sleeping." Same idea, same flaw. Let's clear it up.
What Caffeine (and Windows power settings) actually do
Caffeine is a tiny macOS utility that stops your Mac going to sleep. Click the icon and your screen stays on, no dimming, no screensaver, no sleep. Amphetamine is the more configurable free cousin on the Mac App Store. On Windows — where most Teams users live — the equivalents are apps like "Caffeine for Windows", or simply the built-in settings under Settings → System → Power & battery (set sleep to Never) and Settings → Accounts → Sign-in options (don't require sign-in after you've been away). The core job in every case is the same: keep the machine awake.
That's genuinely useful when you're presenting, watching something, or running a long job. But notice what none of them do: they never move your mouse, and they never press a key. They just stop the computer sleeping or locking.
Why that doesn't keep your Teams dot green
Here's the distinction that trips everyone up. Teams doesn't watch whether your computer is awake — it watches whether you are. Specifically, the Teams client marks you Away after roughly 5 minutes with no mouse movement and no keyboard input registered by Teams. Input, not wakefulness. (And it sets you Away instantly the moment you lock your PC — which is exactly the trigger people disable Windows lock to avoid.)
So you can have Caffeine running, your screen blazing, your PC wide awake — and if you haven't touched the trackpad or keyboard for five minutes, Teams still flips your dot to the yellow clock. Keeping the machine awake and keeping Teams active are two different things, and keep-awake apps only do the first one. Teams' 5-minute idle timer can't be lengthened or disabled either — Microsoft removed that setting.
"But I disabled the lock screen and sleep"
Disabling lock and sleep helps with one specific failure: it stops the instant-Away you get when your screen locks. That's a real win. But it does nothing about the idle timer. Five minutes after your last input, you'll still go Away — the PC is just awake while you do it. To go further, some guides suggest pairing power settings with a separate mouse-mover. That can work, but at that point you're relying on the mouse-mover, not the power settings. A keep-awake app of any kind won't reset Teams' inactivity timer, because preventing sleep and generating input are not the same signal.
What actually keeps Teams active
Two things genuinely work:
- A mouse jiggler (hardware or software) physically moves the cursor every few minutes, which counts as input and resets the timer — as long as the movement lands inside the Teams window. The catch: the cursor visibly moves while you're using the computer, your screen never locks, your machine has to stay on, and on managed Windows fleets IT can spot it. (More in do mouse jigglers work for Teams?)
- A cloud presence tool like Stay Green On Teams skips your computer entirely. It uses your Teams session — captured once via a Chrome extension — to hold an authenticated presence connection from a remote server. Nothing runs on your machine, nothing moves on screen, and you can close the lid.
Caffeine vs the alternatives
| Method | Keeps Teams green? | Needs PC awake? | Cursor stays still? | Works with lid closed? |
|---|---|---|---|---|
| Caffeine (Mac) | No | Yes | Yes | No |
| Amphetamine (Mac, alone) | No | Yes | Yes | No |
| Windows power settings | No | Yes | Yes | No |
| Mouse jiggler | Yes | Yes | No | No |
| Stay Green On Teams | Yes | No | Yes | Yes |
How to keep Teams active without Caffeine
If your goal is a reliably green dot — including when you step away or close your laptop — skip the keep-awake apps and set up a cloud tool once:
- Sign up at staygreenonteams.com (free 14-day trial).
- Install the Chrome extension — it captures your Teams session automatically.
- Open Teams in Chrome once so it can detect your account.
- Set your hours and timezone in the dashboard (or Always On), then toggle it on.
- Quit Caffeine. Close everything. Your dot stays green from the cloud.
Is this against Microsoft's rules?
No. Microsoft Teams' Terms of Service don't prohibit maintaining your presence or using tools to keep your status active. The presence dot is informational, and there's no policy against managing how it appears. If you're on a company-managed Teams account, it's still worth checking your employer's own IT policy.

Frequently Asked Questions
Does Caffeine keep Teams active?
Not by itself. Caffeine keeps your computer's screen and system awake, but Teams decides you're Away based on mouse and keyboard input — not on whether your display is on. With Caffeine running and no input for about 5 minutes, Teams still marks you Away.
Do Windows power settings keep Teams green?
No. Setting Windows to never sleep, and disabling the lock screen, stops the instant-Away you get when your PC locks — but it doesn't stop the idle timer. Teams still flips you to Away after roughly 5 minutes of no input, because Teams tracks activity, not whether the machine is awake.
Is Caffeine the same as Amphetamine?
They're similar macOS keep-awake utilities. Caffeine is the classic, minimal app; Amphetamine is a more configurable free alternative. On Windows the equivalent is the built-in power settings or "Caffeine for Windows". All prevent sleep, but none simulate input, so none keep your Teams presence active on their own.
What actually keeps Teams active?
Something that either generates input Teams can see (a mouse jiggler that moves the cursor over the Teams window) or maintains your presence from outside the device. A cloud presence tool like Stay Green On Teams does the latter from a server, so your dot stays green with no app running and your laptop closed.
Is it against Microsoft's terms to keep your Teams status active?
Microsoft Teams' Terms of Service do not prohibit keeping your presence active or using tools to maintain your Available status. Presence indicators are informational, and there is no Microsoft policy against managing how your status appears. In managed environments, check your employer's IT policy.
