Suggested April 2024 Set Alarm To Automatically Power On Linux Computer

It’s no secret that you can make your computer “sleep” to considerably save energy or battery on laptops. A battery-powered device can spend many days in standby mode. The power draw in this state is incredibly low.

You can wake your computer at any time by pressing the power button or a key on your keyboard. But what if you want it to automatically wake up at a certain time? This can help you automate certain tasks – for example, to download something at 4AM when Internet speed may be much higher. With a bit of command-line magic, you can schedule your device to wake up, take some action and then go back to sleep again.

Besides waking up from standby, you may find it even more useful to completely shut down your computer and power on at certain times. Hibernation is also supported, but Linux systems that use proprietary drivers don’t always wake from hibernation properly.

Test If Your Computer Supports Wake-Up Timers

It’s possible that some computers don’t have the proper hardware to support this feature. However, on most configurations, this should work. You can do a quick test: open a terminal emulator and enter the following command.







Your computer should go to sleep and wake up thirty seconds later. If your device needs more than twenty seconds for standby, increase the wake-up time by changing “30” to a higher number.

Also, test if the computer supports waking up from a complete shutdown.







Regarding -m off, the command manual mentions: “Not officially supported by ACPI, but it usually works.”

If the kernel, drivers and hardware all get along with each other, you should have no problems. If the timers aren’t supported, it’s probably because the hardware and/or BIOS/UEFI configurations don’t meet the requirements. But you might as well try your luck and see if upgrading some drivers or switching from proprietary ones to open source does the trick. You can also try to install a newer kernel.

As previously mentioned, hibernation has issues non-related to the rtcwake command. It does work most of the time but also fails on occasion. When it fails, your screen will remain black or show you an error message.

How to Use the rtcwake Command

The basic use of the command is simple: pick a power-saving method and a time when to wake up. In the previous command the -s parameter was used to specify how many seconds to wait before powering back on. But usually you will want to specify an absolute time, like 9AM tomorrow morning. For that, you use the --date parameter instead of -s.

rtcwake Date Parameter







Note: not all hardware supports setting wake up dates far into the future. This is something that you’ll just have to test to see if it works for your specific device.

Time specification is in 24-hour format. Here’s a relevant screenshot of the command manual with different options for setting the time and date of a wake-up event.

“YYYY-MM-DD hh:mm” means, year, month, day, hour and minute – for example: --date 2023-02-28 15:00 for the 28th of February, year 2023, 3PM.

rtcwake Dry Run

You can add another parameter to rtcwake, -n, to display when the alarm will be set.








This is a “dry run,” meaning it doesn’t actually set an alarm and only “pretends” to do it. It’s useful to add -n when you want to test if your date specification is correct. Once you’re sure it’s right, just use the command without -n to set the actual wake-up time.

rtcwake Power-Saving Methods

The relevant options you can pass to the -m parameter are:

-m mem – normal standby mode you’re familiar with from the shutdown menu.

-m disk – hibernate mode that saves memory content to storage device. Not recommended when using proprietary drivers.

-m off – normal shutdown.

-m disable – cancel a wake-up event you previously set.

-m no – don’t power off or standby, just set a wake event. For example, you can set a wake-up time for tomorrow morning, then continue to work on your computer. When you’re done, shut down normally, and the device will automatically power on in the morning.

-m show – show wake-up events (previously-set alarms) currently active.


It’s up to you to find creative ways to use rtcwake. As a starter, this can help you find the computer fully booted in the morning. This way you skip the boring boot process which can take more than a minute on some systems. You could also install an utility, such as at, to automate tasks that your computer can run after waking up. We might even explore that option in a future tutorial.

How To Change What The Power Button Does On Your Computer.

If you have a habit of accidentally pressing the power button on your computer and triggering a full shutdown. This article will show you how to change what the power button does when you press i. Make it: Do nothing, Sleep, Hibernate, Shut down or Turn off the display. The choice is yours!

Whether you a hardcore gamer, stock or crypto trader, graphic designer, hacker, etc, the physical power button on your computer probably the most important button you press in your day to day life. Give or take a few extreme circumstances. What a lot of people don’t know, however, is that the power button on devices running Windows 10 can be changed to do more than simply turning your PC on or off.

At some stage, we’ve all accidentally pressed the power button on our Windows 10 PC and had it completely shut itself down at the worst possible time…I just recently had this happen between save points in Final Fantasy and cost myself a solid hour of character level grinding… All is not lost though, it has inspired me to put this guide together to help others avoid this accidental mishap!

How do you change what the power button does on Windows 10 computers?

Before we get much further into this guide, it’s important to mention that these changes will only affect what the power button does when your computer is turned on. When your computer is powered off, the power button will always turn it back on. These changes will allow you to change what the power button does once your computer has booted into Windows. For example, you can set it so the power button does nothing when pressed, restarts your system when pressed or puts your computer to Sleep when pressed.

Don’t forget to make the changes for On battery and Plugged in as the buttons will do completely different things depending on how you are using your device.

Note: This screen will look a little different on desktop computers, however, everything works the same.

If you just want your computer to turn on using the power button then do nothing until you shut it down in Windows, set it to Do nothing. This will prevent any accidental power downs but still allow you to hold down the power button to force shut down your PC should it become unresponsive and freeze up at any stage.

Can you also change what happens when you close the lid on your laptop?

From this screen, you can also change what happens when you close the lid on your laptop. Set it to Sleep, Do nothing, Hibernate or shutdown. For obvious reasons turn of the display isn’t listed… Anyway, that wraps up this guide, I hope you’ve found it helpful and I hope you can use it to prevent yourself from making the same mistake I did! We all know how boring level grinding can be.

Safe Alarm 3 Adds Powerful Features To Your Iphone Alarm

So many people rely on alarms from their smartphone to wake up in the morning that when a major new jailbreak tweak comes out that improves the stock alarm system on the iPhone, it’s a big deal.

Safe Alarm 3 by Douglas Soares is a noteworthy release in Cydia that expands upon the alarm system in iOS by giving you a trough of new options to configure, including new ways to be woken up.

Smart Alarm has been changing the way jailbreakers customize their alarms for over two years, but it gets better with each release. This tweak includes per-alarm settings that you can apply to individual alarms, or all-inclusive alarm settings that you can apply to all alarms as a whole.

A better way to create alarms

After installation, a new set of options are tacked onto the usual at the bottom of the alarm creation interface. These are the per-alarm settings we mentioned earlier:

With far more options than the stock setup, Smart Alarm 3 lets you do all of the following things that the stock settings don’t:

Choose the individual days of the week that the alarm goes off

Use alert tones and playlists for alarms in addition to ringtones and songs

Choose a custom snooze duration

Choose a custom volume level for the alarm

Choose a fade-in duration for the alarm

Vibrate on both ring and silent

Choose when the alarm gets automatically dismissed

Configure a calculator so you’re forced to solve math to dismiss the alarm

These options are great, especially the one that lets you choose a custom volume level, because how many times have you accidentally changed your volume level or left your iPhone on silent mode when your alarm was supposed to be going off? Oops!

Forcing yourself to solve a math problem is also great, because it ensures you’re actually awake at the time you acknowledge the alarm. In addition, being able to choose a custom snooze duration is something users have been asking Apple to implement for ages, and since they haven’t answered the requests, Smart Alarm 3 does!

Besides the per-alarm options, you’ll find a bevy more options in the Safe Alarm 3 preferences pane in the Settings app:

Here, you are going to find options for:

What happens when you press the sleep button during an alarm

What happens when you press a volume button during an alarm

What happens when you press the Home button during an alarm

Disable automatic locking when an alarm is going off

Configure the screen to flash colors when the alarm is going off

Switch between light and dark mode in the Clock app

Enable tapping on alarms to edit them instead of the usual convoluted process

Allow mass-editing of alarms at one time

Enable a button to toggle all alarms on or off at once

Open the Alarms tab of the Clock app from Control Center’s shortcut

And configure various other general settings…

With these options, you’ll find some incredible new ways to interact with your alarm. Being able to choose what each button on the device does during an alarm execution is critical for those who like using certain buttons more than others, and the ability to make the screen flash colors as an alarm goes off can be an essential part of the wake-up process for those hard at hearing.

Here’s an example of what the screen flash looks like:

Besides those praises, the UI and aesthetic improvements to the Clock app are also noteworthy. The option to toggle the lighter UI in the Clock app might be better for some with vision issues, having the option to make alarm editing easier saves a bunch of time, and using the Control Center shortcut to get you to the Alarms tab makes accessing your alarms oodles easier.

Now to get on to the last four cells in the preferences pane…

Alarm Notification

This preferences pane lets you choose how the alarm notification behaves. You will find options for:

Showing buttons for interacting with the notification when on the Home screen

Showing or hiding the background blue when on the Home screen

Invert the Snooze/Stop buttons when on the Lock screen

Time Until Alarm

This preferences pane gives you options for seeing how much longer you have until an alarm goes off. You’ll find settings for:

Within the Clock app

Toggling the feature on or off

Hiding the information from inactive alarms

Choosing the font size

Choosing the time format

Choosing the position for the information

On the Lock screen

Toggling the feature on or off

Choosing the font size

Choosing the time format

Choosing the position for the information

Choosing rules for hiding the information

Choose what information is displayed

Activator Gestures

Because the tweak ties in with Activator, you can assign gestures to all of the following options:

Stop alarm

Snooze alarm

Turn off all alarms

Turn on all alarms

Toggle light or dark mode in the Clock app

Anything you set here gets applied to all new alarms you make going forward by default. The options here are just about the same as those that you’ll find in the per-alarm settings we showed you at the beginning of this post.

Because we already went over those earlier, there’s no sense in repeating ourselves with the available options…

Wrapping up

Safe Alarm 3 was designed with the everyday alarm user in mind. The added customization features allow you to power through the alarm schedule creation process and do more to ensure you wake up.

Because I’m one of many who have a problem with the lack of customization iOS’ alarm system has to offer, I have to give Safe Alarm 3 a thumbs-up.

A tweak worthy of praise, Safe Alarm 3 is available for $1.99 in Cydia’s BigBoss repository and can be had for a discounted price of $0.99 if you own any previous versions already. The tweak is intended for iOS 10 devices, so if you’re jailbroken on iOS 9, you may want to check out Safe Alarm (iOS 9) instead.

So if you are a collector or an emerging artist who wants a platform to showcase their NFTs, and maybe find a potential buyer or a casual art admirer, with the help of Digital Collectibles, Instagram is trying to build a new type of community on its platform just like they did it with Reels.

How To Enable Scan To Computer On Windows 11

How to Enable Scan to Computer on Windows 11 [7 Ways]




Scanning makes the storage of photos and other files more flexible and offers the option to access them anywhere. Your printer must have a scanner to use.

Many users complain that their printer is unable to scan to the computer after upgrading to Windows 11. Altering the compatibility mode of the scanner may solve it.

Some of our readers also claimed Microsoft tech support told them Windows 11 will not recognize all printers. Downloading the latest driver from the manufacturer’s platform may fix it.



Try Outbyte Driver Updater to resolve driver issues entirely:

This software will simplify the process by both searching and updating your drivers to prevent various malfunctions and enhance your PC stability. Check all your drivers now in 3 easy steps:

Download Outbyte Driver Updater.

Launch it on your PC to find all the problematic drivers.

OutByte Driver Updater has been downloaded by

Are you in search of information on how to enable scan to a computer in Windows 11? Well, the OS is enabled to scan an image, document, and any other compatible files to your computer.

They can then be saved anywhere you prefer and probably uploaded to the cloud, hence, accessible from anywhere you want.

Dedicated software controls most scanners. They are made available by their manufacturers.

It is also possible to control them using an application provided by Microsoft itself or one of the best scanner apps for Windows 11. But then, users have complained that they experience some problems while trying to scan.

Why will my printer not scan to the computer?

Generally, the reason for Windows scanners not being detected can be broadly categorized into two: situations when the computer does not detect the printer at all, and instances when the printer is detected but scanning does not work.

These issues especially the latter can be caused by one of the following reasons:

Faulty cable connection – Using a bad or incompatible cable would prevent a successful connection between a computer and the printer. This will inevitably hinder the scan from working.

Error in wireless connection – The use of non-cable connections such as WiFi doesn’t guarantee there will be no error. Issues with the connection will automatically affect the ability to scan.

Outdated printer driver – Whenever peripheral hardware like a printer is connected to a computer, a driver is responsible for smooth communication. Any problem with the driver will directly tamper with scanning.

Insufficient memory on the system – If you have a low memory space on your computer, scanning may not be possible if the expected result would exceed the available storage.

Disabled Windows Image Acquisition (WIA) Service – This is a special service on the Windows Operating System designed to support the optimal function of scanning. Disabling it will prevent the scan from effectively executing.

Disabled Shell Hardware Detection Services – The ShellHWDetection manages Autoplay hardware events in Windows. This feature allows the computer to detect images and triggers needed applications to display them. It has to be enabled for the scan to work.

How do I enable scan to computer? 1. Setup the scanner 2. Check the wireless connection

Here are some of our recommendations:

Make sure the WiFi, computer, and printer are all within range. If this is not the case, adjust the location and, if impossible, switch to an alternative by connecting using cable instead. You can check out wireless printers compatible with Windows.

For the wireless connection to function, you might need to restart the WiFi.

It is also recommended that you check if the printer is wireless compatible to enable scan to a computer.

Instead of updating drivers manually, you can use another method to manage all your drivers more efficiently.

With a dedicated driver updater, you have full support to install or update old drivers on your system. Not only this, you can handle drivers’ errors and repair them right away.

The software will scan your Windows 11 PC for outdated driver files and detect them rapidly. Afterward, you can choose one driver or many others to start the update.

⇒ Get Outbyte Driver Updater

4. Reduce scan resolution

This method is recommended in case your PC is low on can device memory. It would also work for readers in search of solutions on how to enable scan to computer on Windows 10.

5. Activate Shell Hardware Detection Services 6. Enable Windows Image Acquisition service

Expert tip:

7. Tweak Compatibility Mode Why is my computer not detecting my scanner?

In the second section of this solution guide, we listed the common reasons why Windows may not enable scan to computer in Windows 11. Also, not all printers are designed with scanners, so, it is important to ascertain if yours possess the feature.

Users who have just upgraded their Windows 11 usually face hiccups with scanning. Sometimes, to fix this, you will need to go and download the official software for the scanner on the manufacturer’s website.

Another thing that could make your computer not detect the scanner is when the scanner software is not compatible with the PC.

What can I do if my Windows scanner is not detected? 1. Troubleshoot printer 2. Download scanning software from the manufacturer

Make sure that your VPN is disconnected when visiting your printer manufacturer’s official website to get the best recommendation for your need.

Meanwhile, there are lots of free scanning software tools for Windows 11 on the market today that work seamlessly with any computer with the required compatibility.

One of them is the Windows scan developed by Microsoft and available for download in the Microsoft Store.

If you are looking for alternatives that are both effective and free, we have a review on free scanning software for Windows 11/10 to help you decide which to choose.

What scanners are compatible with Windows 11?

Literally, all printers with scanners are expected to be compatible with Windows 11, but some of our readers have reported that after contacting Microsoft Support when they had issues, they were told the latest Windows OS version is not compatible with all printers.

The reason for this is many, but one specific one is that the manufacturer hasn’t updated their drivers to synergize with Windows 11. This is a move many big boys in the printing industry don’t hesitate to act upon.

When searching for scanners that are compatible with Windows 11, check out our review of the best printers with feeder scanners to make an informed decision.

Experiencing any issue with scanning all because you updated Windows is something that could be frustrating. We hope any of the solutions discussed so far has helped you fix the problem. If not, also take a look at our article on what to do if the HP scanner is not working on Windows 11.
