It could be a Ghost. Or a demon. Some things that caused this same issue for me were: I had a very sensitive mouse and even though I was in bed, the mouse would move just very slightly but not noticably, and that woke the PC. I have also had a problem with USB devices (keyboard/mice/Wireless adapters). Sometimes, and usually over a period of several ...

There is a certain event in the Event Viewer that may help you troubleshoot spurious wake-up issues. You can find it under Windows Logs > System; look for "Power-Troubleshooter". However, as you see, it's not always helpful. Mine shows "Unknown" even though I woke it up using the power button. As an IT admin, I can tell you that spurious wake-ups are ...

Tricky one. Last time I had this, it was a new motherboard with a Realtek network card. These have a "wake on any packet" set, which is annoying. Go to the network adapter properties, power management tab and tick the "Only allow a magic packet to wake the computer". For me, no more waking up at random. Realtek need a ticking off for that one. I think it ...

If you pop open Task Scheduler and click Create Task, there's a check box under the Conditions tab that will wake the computer to run the task: You could run your batch job from there, and create another task to put the PC back to sleep, or run the shutdown command in your batch job after it finishes (as long as there's a way to tell it has finished.) ...

This can be trivially achieved using cron with some specific parameters to ping. Create a file with a name like perhaps /etc/cron.d/ping-my-repeater. For contents, pick one of the below. If once per minute is adequate, try this: * * * * * root ping -n -c 1 -W 1 $REPEATER_IP_ADDRESS If twice per minute is desired, try this: * * * * * root ping -n -c 2 ...

In addition to the answer suggesting the use of the Task Scheduler, which may be the best option to use, here are two other things to consider for switching on the computer: Some BIOS have an option to turn the PC on at scheduled times pro: windows doesn't have to sleep, can be fully shut down. (if it turns out that the Task Scheduler can only handle it's ...

Simple disable Allow Wakeup Timers or some thing lime that in Control Panel > Power Options > Advanced Power Settings. Otherwise, if it doesn't work, you may need to go to device manager and, for each device, go to properties and then the power options tab (Not all devices have this). Here, you should find some checkboxes like "Allow the computer I turn ...

In Windows 7 (log in as an administrator if not already) Control panel -> power options if there isn't a default plan there that does what you want it to (different resellers will include there own power plans such as "HP recommended" therefor it's hard to say what pre-configured options will display for you. You can edit existing palns but you might ...

I'm encountering the same issue (Windows 8.1) and none of the "power setting" solutions worked for me. I ended up playing a movie file, an audio file... anything that cause regular accesses to the disk. For less overhead, it should be feasible to write some script that just regularly access the disk, before it goes to sleep. edit: here is a quick script ...

There could be multiple things that could cause this. For starters check the following Go into your computer's BIOS as @OmarAsifShaikh suggests go to power setting/power config/Power Management depending on your computers' bios manufacturer. There should be setting called "Wake on Alarm", check to see if it is enabled. This wakes the computer on a set ...

Open command prompt, and use the following command powercfg lastwake It should tell you what hardware device caused the computer to wake up. As to why the device woke up the computer, there could be many reasons, some of which are detailed in IUnknown's answer

Not sure about 7, but on Vista you'd do Windows button -> Control Panel -> Administrative Tools -> Task Scheduler. In Task Scheduler, click on "Task Scheduler Library" in the left-hand column, an in the top center column you will see a list of scheduled tasks. Eg, there's apt to be one for Adobe Flash update, Google Update, etc. For each suspicious task, ...
