Power Timer

Shut the PC down, restart it, put it to sleep or hibernate, lock it or sign out, in four ways: after a while (say in 1 hour), at a time (say 23:30), when nobody is using it, or when the net goes quiet, to shut down once a game or an update has finished downloading without you sitting there. A sound and a 60-second warning come first, and you can put it off or cancel.

Download

Power Timer's window in English: buttons to shut down, restart, sleep, hibernate, lock or sign out, the tabs for when, the time buttons, the option to force programs to close, and a sentence saying the PC will shut down in 1 hour — Choose what to do and when. The sentence below says plainly what will happen and at what time. Then press start.

Power Timer's window while counting down: the time left, 1:29:58, in large figures, the time it will shut down, and the buttons to put it off 15 minutes, cancel and minimise — While it counts down you can minimise the window; the time left shows in its name on the taskbar.

What it does

Six things to ask forShut down, restart, sleep, hibernate, lock the screen, sign out.
Four ways to say whenAfter a while (15 minutes to 4 hours, or your own up to 48 hours) · at a time (if it has passed today it means tomorrow) · when idle (nobody has touched the mouse or keyboard for N minutes) · when the net is quiet.
Shut down once a download is done"When the net is quiet" watches all the data through the network cards. When it stays under the speed you set (10 to 2,000 KB/s) for the time you set, the download counts as finished.
A 60-second warningThe window comes to the front with a sound and flashes on the taskbar. Put it off 15 minutes or cancel. With "when idle", just touching the mouse cancels that round (locking the screen has no warning because nothing is lost).
The time left on the taskbarMinimise the window and you can still see how long is left in its name.
Remembers your last choiceNext time it is filled in as before.
No administrator rightsNo admin prompt, no shutdown.exe or PowerShell: it asks Windows directly.
No installUnzip and double-click. Copy it to a USB stick to use on another PC.

Download Power Timer

The download is being prepared. Coming soon.

Getting started

Download the zip above, right-click it → Extract All… into a folder of your own, such as Documents or a USB stick. Don't run it from inside the zip, and don't keep it in Program Files: the program needs to write files beside itself when it updates.
Double-click PowerTimer.exe. The first time, a notice about usage statistics appears: read it and click Got it.
Choose what the PC should do, then when. The bold sentence below says what will happen, such as "Will shut down in 1 h → 23:30".
Click ▶ Start the timer. The window minimises by itself (untick "Minimise the window after starting" to stop that). Do not close the program's window: the timer lives in the program, so closing it cancels the timer.
For 60 seconds before it happens the window comes up. Click Put off 15 min or Cancel. If you do nothing, it does what you set.

The first time you run it, Windows may show a blue "Windows protected your PC" screen because the program is not signed with a paid certificate. That doesn't mean it has a virus. If you downloaded it from this site, click More info (the link under the warning), then the Run anyway button that appears (once).

Good to know

Force open programs to close is off by default: normally Windows waits for programs to save, and if one asks "save?" with nobody at the PC, the PC will not turn off. Turn this on when you need it to go off for sure, but work that is not saved is lost (it applies to shut down, restart and sign out).
When the net is quiet: a network that was quiet before the download began counts as quiet, so press start once the download is running. Set the speed higher than your network's idle chatter (usually under 50 KB/s).
When idle looks only at this account's mouse and keyboard. Watching a film or playing music without touching anything counts as idle.
Sleep: on some PCs where hibernation is on, Windows hibernates when a program asks for sleep. That is Windows's habit; turn hibernation off in Windows if you do not want it.
It does not survive the program closing: if the program is closed, the power goes, or the PC restarts before the time, nothing happens, and you set it again.

Requirements

64-bit Windows 10 or Windows 11. Setting a timer needs no internet connection (the internet is used only for ads, usage statistics and updates).
The program's window uses WebView2, which comes with Windows (without it, the program opens in your default browser instead).
The program is in English or Thai: it picks the language from Windows and you can switch under ⚙️ Settings → ภาษา / Language.

Ads and removing them

Every feature of Power Timer is free. It shows a small ad bar at the bottom of the window (one line of text, or a picture of 468×60, 728×90, 970×90 or 320×50, scaled down when the window is narrow) and, when the window is wide enough, an ad box beside the timer (text, or a picture of 300×250 or 300×600, scaled down to fit the window's height). To remove the ads, ask for a key at contact@freesabai.com, then click Remove ads on the bar, paste the key into Ad-removal key and click Enter key. Keys are checked on your computer, without the internet.

Privacy

What you set (what to do and when) stays on your computer; the program keeps only your last choice there, to fill in next time. Nothing about this computer, no specs, no machine or serial numbers, no computer name or user name, and nothing you have set the timer to, is sent anywhere. Power Timer sends only a usage report at most once a day (a random ID for the installation that the program made itself, not taken from the hardware, the version, the Windows version, the Windows language and region, whether a key is in use, and how often each ad was shown). The first time it opens, the window shows a notice about this before anything is sent. Switch it off by clicking Usage statistics: on under ⚙️ Settings → Privacy. You are still told about new versions, because the latest version number comes with the ads the program already downloads. When you click to update the program, it downloads the new version from freesabai.com and sends nothing else. The full details are in our privacy policy.

Updating and removing

When there's a new version of Power Timer, even with usage statistics off, a strip under the top of the window says the new version is out (Later hides the strip until the program is next opened and leaves an ⬆ Update to button with the new version number at the top of the window, next to ⚙️ Settings, for later). Click Update now on the strip, or that button, and the program asks first; click Update now and it downloads the new version from freesabai.com, checks our signature, then closes and starts again by itself. Your settings stay; other files in its folder are only replaced when they are Power Timer's own, such as the README.txt from the zip. (Click See the download page if you'd rather download it yourself from the program's download page on freesabai.com.) An update closes the program, so a timer you had set is gone.
To check yourself at any time, go to ⚙️ Settings → Check for a new version (the program asks freesabai.com only when you click this button). If the check fails (for example without internet), the program opens its download page on freesabai.com. The program never downloads a new version without your click.
If it can't update itself (for example its folder can't be written to, or the download fails the checks), it opens the program's download page on freesabai.com instead. You can also close the program and replace PowerTimer.exe with the new one; your settings stay.
To remove: close the program and delete its folder. What it remembers about this computer (the settings, your last choice, the ad-removal key and the random ID for the statistics) is in %LOCALAPPDATA%\PowerTimer; you can delete that too.
