I'm almost reluctant to post this notice in case I jinx us; but following two foiled attempts earlier this month, we think we're finally able to take a little beach holiday for the next few days.  I'll still be online, but not as regularly.  I thank you for your patience.  Damien.

Old laptop waking me up

Recommended Posts

Hi Brian! I have an old laptop (running Windows 10) in my bedroom that I like to keep handy for tasks that are awkward on a tablet. It runs well for this light use, and shutting the lid to put it to sleep doesn’t cause problems (except the one I’m about to complain about). Because it’s slow to boot, I don’t want to shut it down every single time. 
 

But.... sometimes it wakes up in the middle of the night and makes noise for a few minutes. I’m a light sleeper. I’ve looked at every scheduled task I could think of, disabled a sleep wake timer setting, but the problem persists. Do you have any suggestions I could try?

This isn’t urgent, obviously, just figured I’d ask. Thanks! (And happy new year!)

Now this is a unique problem. I usually get questions (in real life) to make sure a device doesn't go to sleep, you are the direct opposite. The short answer is, I have no idea. :D  I did find this article: How to Stop Your Computer From Randomly Waking Up From Sleep Mode. I also found this article: What to do if your laptop wakes up from sleep on its own.

I'm thinking it might be some sort of scan from virus software, possibly Windows update running, even the manufacture's software that is looking for driver updates. If you are running a Cloud Service, it could be doing a maintenance cycle from there and looking to sync things. Basically, it can be anything. Even a external HD or another device that is plugged into it. If your laptop is configured for DHCP, I'm wondering if the lease time is expiring and the laptop is hunting for a new IP address? (My thinking, if this is happening, the WiFi Adapter is waking up the system, but this is a long shot. Again, I'm just throwing things out there as I think of them.)

If you are familiar with the Command Prompt I want you to try this:

  1. Click the Start Button
  2. Immediately type CMD (Just start typing, don't worry about putting anything into a search box.)
  3. Now, this is the important step, the Command program should appear in the list, if you see it, great...but the important thing is to look towards the right column and look for "Run as Administrator." If you don't see Run as Administrator in the right column, that's OK, just simply right-click on the Command Program in the Start Menu and select Run as Administrator. I don't care how you accomplish this, just make sure the Command Window is opened with elevated privileges. (Yes, even though you might be logged in as an Administrator, you still need to do this.)
  4. Once the Command Prompt Box appears, type: powercfg -lastwake. If you are lucky, something obvious will appear. If not, you are going hunting for a solution.

If you'd like, I want to see what powercfg comes up with. Post a screenshot here with the results. (You can use the Snip-It Tool.) Maybe we can put our heads together in figuring out what is causing this issue. Oh, type exit and hit enter to close the Command Window Box.

Edit: You might have to wait to do the powercfg -lastwake command after it wakes up during the night. I know this sucks as you want to get a full night's sleep, but we need to figure out WHAT is causing the issue, and that needs to be done just after it happens. The good news is, if it's obvious, we can form a plan of attack.

From this morning, but I don’t think it woke up last night. Will try again when it does. Have a great weekend!

Yeah, it doesn't look like it woke up last night. You also want to make note of the day/date that it woke up. If this happens every Tuesday or early Wednesday Morning (2:00AM,) it could be Windows Update checking the Microsoft Servers since patches are typically released on Tuesdays. Also, if you want dead silence and are determined to keep using this laptop, you might have to upgrade/replace the Hard Drive with a SSD model. In addition to the CPU fans, you have a rotating disks in the HD and that motor can get loud.

You might be onto something with the weekly schedule. I’ll track that. It’s ten years old though, I wouldn’t spend money on it. Will update soon!
