Windows Vista Laptop wakes itself out of hibernation at 3 am

    My laptop has picked up an annoying habit. Every now and then, it turns itself on at about 3 am. Since the sleep mode no longer works for this laptop, I put it into hibernation instead. That has worked. But now this.

    The laptop is a Compaq Presario V6000, running Windows Vista with Service Pack 2. It is about 3 1/2 years old. As it is getting old, the laptop has problems with various things.

    I would like to figure out what the problem is. When it turns itself on, the laptop heats itself up until the fan is so loud it wakes me up. I am typing this at 4:22 am local time. As I am getting older, this is getting very old, very fast.

    Could it be that the laptop is checking for updates? That's the only thing I can think of.

    It could be carrying out some scheduled task.

    See if you can find anything in Task Scheduler.

    Any specific reason why you don't shut the laptop down each night?

    As you suggested, I looked in the Task Scheduler. It does say that a Scheduled Defrag is set to run every Wednesday morning at 1:00 AM. But today was a Friday morning, and the computer turned on about 3:30 AM.

    Still, that may be it. I'll try to turn that off.

    I never know each night when I am done. So I like to just shut the lid and have it hibernate, in case I think of something I want to do on it later.

    Every day or two I do turn the laptop off, and then restart it when I want to use it.

    Hi Daanii. Have you looked in the labtops BIOS for any setting related to a scheduled turn on time? There could be a setting in the BIOS that turns on the computer especially since a Scheduled Task may not be the culprit.

    When you shut down the labtop does the computer also turn on at 3 am or only if you put it into hibenation?

    Run following command:
    powercfg -lastwake
    It should tell you what the culprit is.

    I looked in the BIOS, but could not find any setting related to a scheduled turn-on time.

    I do not remember the laptop ever turning itself on while being turned off. Just from hibernation.

    I'll try that next time it happens. It happened again this morning. I woke up at 3:30 am to hear the laptop running. That's unusual -- I cannot remember it ever happening so quickly before: today after having happened two days ago.

    But I had to hibernate the computer and waken it before I saw Broni's messaage. So when I ran the command, it did not have the morning wakeup event listed, just the last one.

    Thanks for the replies and suggestions.

    You can run that command at any time. You don't have to wait for the issue to happen again.

    I see. Then I'm not sure how to interpret the results. When I do the command, I get:

    Unfortunately it doesn't list the source:
    Most likely, it's not software related then.

    When I searched for more information about powercfg, I found this. But I did all the steps, and found nothing that would indicate a problem.

    To be sure, I decided to go down the list of steps in the list linked to in my last posting.

    That caused a big surprise. I had apparently NOT checked Windows Update. Because when I did, I found that the laptop was set to install updates every day at 3 AM.

    That has, of course, now been changed. I suspect that will resolve the problem, so I'll mark this thread resolved.

    Just goes to show how what I think I have done, and what I have actually done, are often too different things.

    Yes :)

    And also check for auto scans times for Windows Defender or MSE - if you use either of them - why MS assume that all computers are on 24/7 is beyond me, but they do :)

    Good suggestion. I'll check those.
