Wake Up Event by BIOS or OS: How to Set and Troubleshoot

Well, let me tell ya, there’s this thing with your computer where it can either wake up from a sleep mode all by itself, or it can wait for somethin’ like a keypress or mouse movement. It’s like when you take a nap and someone comes and shakes you awake, or you just wake up on your own when the sun comes up. Now, for computers, we call this a “wake-up event,” and it can happen in two ways – either by the BIOS or by the operating system (OS). That’s right, the BIOS and the OS both got their ways of makin’ your machine come back to life after it’s been snoozin’ for a bit.

So, first off, if your computer is sleepin’ real deep and you want it to wake up with just a little nudge from your keyboard or mouse, there’s somethin’ you need to check in your BIOS settings. If you’re not familiar with the BIOS, don’t worry, it’s just the big ol’ software that makes sure your computer knows how to do the basic stuff like turnin’ on and off. It’s kind of like the brains of the machine before it even lets Windows or any other programs run.

Now, in the BIOS, there’s an option called “Wake Up Event.” It’s the setting that decides whether the computer will wake up all by itself or if you need to give it a push. If you set it to “BIOS,” that means the BIOS is in charge of wakin’ the computer up. It’ll handle things like turning on the monitor and keyboard, and doin’ a quick check to make sure everything’s good. On the other hand, if you set it to “OS,” that means the operating system – like Windows – will be the one responsible for tellin’ the computer when it’s time to wake up.

Some folks, especially with newer computers, like to have the OS do all the wakin’ up. You just go into the “Device Manager” in Windows and let your keyboard or mouse know that they have permission to wake up the computer whenever they feel like it. This can save you from having to go mess with your BIOS settings every time you want a change. It’s like lettin’ your keyboard and mouse have a little more control over things, like them being the ones to ring the bell when it’s time to get up.

But, not all computers behave the same way. For instance, a feller might have an MSI motherboard, like the B450 Mortar Max, and run into some trouble where the computer just won’t wake up from sleep no matter how much he shakes the mouse or presses the keyboard. In such cases, some folks found that updating the BIOS to the newest version or playin’ around with the power settings in Windows helped fix the problem. It’s always a good idea to make sure both the BIOS and Windows are up to date, ‘cause these updates can fix bugs and make things run smoother. So, don’t be shy about checkin’ your settings and givin’ your system a little tune-up now and then!

Now, let’s talk about a thing called “Wake On LAN.” That’s when your computer can be woken up from another computer through the network. It’s like when you’re sittin’ out on the porch, and you yell across the field to someone to get their attention. With Wake On LAN, your computer can be woken up by another device that sends a signal over the network. To use this, you’ll need to enable it in the BIOS, and make sure your computer’s connected to the internet or network in a way that it can listen for that special “wake-up” signal.

All this stuff is what’s known as “Power Management” in the BIOS. It’s a way to save energy and keep your computer runnin’ when you’re not usin’ it, but still make sure it can pop back up when needed. Some of these settings, like the “PME Event Wake Up,” are part of that. They decide whether the computer can turn on by itself, or if it’ll just stay asleep till you give it a nudge. These settings are there to help you customize how your computer behaves when it’s not in active use.

If you’re still havin’ trouble gettin’ your computer to wake up when you want it to, it might be worth checkin’ both the BIOS and OS settings to make sure they’re playin’ nice with each other. Sometimes the two need a little help from each other to make sure the computer is workin’ the way you want it to. And don’t forget – a little tinkerin’ with updates, both for the BIOS and your operating system, can do wonders to get everything back on track.

So, in short, whether you want your computer to wake up by itself, or you want it to listen to your mouse and keyboard, it all comes down to how you set up that “Wake Up Event.” You just gotta decide whether you want the BIOS or the OS to do the job, and make sure everything’s set up right. Once that’s sorted, your computer should be able to wake up when you need it. It’s like gettin’ the alarm clock just right – not too early, not too late. Happy computin’!
