Fake Shutdown Screen
The fake shutdown screen prank plays the "Shutting down…" spinner every operating system uses, then fades to solid black and stays there. From across the room the computer looks off. It isn't — it's a browser tab holding on a black screen.
The clever part is what happens next: they press the power button, the machine appears to do nothing, and now they think it won't turn on. Want it to look broken rather than off? Boot Device Not Found is the one that really lands. Want it to look busy instead? Try endless loading.
Press F11 for maximum realism. Tap or press Esc to exit.
Add the prank to their home screen and it runs like a real app — no browser bar, no tabs, no URL, nothing to give it away.
How to use the fake shutdown screen prank
- Tap Launch Full-Screen Prank above (or press F11 once it's running).
- Leave the device where your victim will find it. It'll look completely real.
- When they panic, tap the screen or press Esc to reveal it was a joke.
For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
Frequently asked questions
Did the computer actually shut down?
No. The browser tab plays a shutdown animation and then holds on black — the machine is fully awake the whole time. Move the mouse and press Esc and everything is exactly where it was.
How do you fake a computer shutdown?
Open this page and press F11 for fullscreen. It plays the shutdown sequence on its own and then holds on a black screen indefinitely, so you can start it and leave.
Why is a black screen more effective than an error?
Because it removes all information. An error tells you what to search for; a black screen makes you doubt the hardware, and people jump to "it's dead" much faster than they jump to "someone opened a website".
What happens if they press the power button?
The real machine will respond normally — it may genuinely sleep or shut down, since the page can't stop that. It's worth knowing before you set this up: if they hold the button down, you get an actual shutdown rather than a prank.
Does the screen stay black permanently?
It holds indefinitely, though the computer's own display sleep may kick in after a while — which, if anything, only makes it more convincing.
Can I use it as a plain black screen instead?
For that, use the dedicated Black Screen tool — no shutdown animation, just black, which is what you want for OLED power saving, backlight-bleed checks or a clean second monitor.
Does it work on a phone?
It does, but it's far less convincing — phone shutdown screens look different, and a black phone screen just reads as locked. The fake low battery screen is the mobile equivalent worth using.
Can I get in trouble for using it?
The page is harmless and legal, but there's a real cost if someone believes a machine has died — they may force-restart it mid-task and lose work, or take a perfectly fine laptop to IT. Own up quickly.
