My Windows PC randomly wakes from sleep because the mouse moves like 1/2000 DPI in some direction because of air movements or some heavy truck driving by nearby my house.
Razer mouse, in case it matters.
I think Microsoft could save a whole lot of energy usage globally by pushing a more sensible algorithm with an update.
- orangepurple 4y agoIf it's wireless flip the switch underneath the mouse to power it off.
- tpmx 4y agoThat doesn't scale. You need to make it frictionless to the end user. (And I'm using a wired mouse since I hate changing batteries.)
- dvtrn 4y agoPardon my confusion but… …what? Is there a laugh being had that’s going over my head? I’m still kinda waking up
- Rebelgecko 4y agoMost people are lazy. A software solution is going to be more effective than a wetware one.
- tpmx 4y agoAnd those that aren't lazy will not automatically learn about what they "should do". Nevermind that it's just stupid to tell people what to manually do when it's possible to automate it via software.

- _flux 4y agoThat would save only a wee bit of energy globally, though.
- DantesKite 4y agoIt also wouldn’t scale as well as a global update.
- vladvasiliu 4y agoDoes that work for all mice you may plug, or would you have to remember to configure it whenever you use a new mouse (or possibly even if you plug it in another port)?
- kaetemi 4y agoThat gets wiped on every other Windows update these days.
- leetcrew 4y ago> Or you could drop your mouse DPI and raise its sensitivity in Windows. the kind of person who buys a hi dpi mouse is not going to want to do this. there are precision issues with windows mouse sensitivity settings other than 6/11. are they noticeable by a human? probably not. but it defeats the purpose of buying that kind of mouse to begin with.
- tpmx 4y agoI'm probably a special case, but I'm only looking at ergonomics and the number of programmable buttons. I want two buttons on the left side of the mouse (mapped to back/forward) and two buttons to the right (mapped to Page Up/Dn). If you haven't tried web browsing like this you don't know what your're missing out on :). That leads me towards high DPI gaming mice, but I'm not a gamer.

- ericabiz 4y agoIn case anyone else has this issue, at least it’s pretty easy to turn off: Launch Device Manager. Go to Mice and other pointing devices. If you’re using a Bluetooth mouse, go to Human Interface Devices. Right-click on your mouse and select Properties. Select the Power Management tab. Find the option: Allow this device to wake the computer. Uncheck it.
- tpmx 4y ago(Thanks, I just did that. It worked.) This demonstrates that it's in Microsoft's power to save a whole lot of electric power usage globally by pushing a software update.

- TonyTrapp 4y agoI have never seen this happening, with many machines and different mice. Maybe it only happens with specific mice? Anyway, want I want to say is that the power usage across the world due to this misfeature is maybe not quite as dramatic as it may appear.
- tpmx 4y agoI's a high-DPI "gaming" mouse. I use it because it has lots of programmable buttons. Gaming seems like quite a big thing with Windows users these days though and they seem to want high-DPI mice, so I do think it could actually be a sizeable thing outside of large office environments.
- xboxnolifes 4y agoSure, but those kinds of updates are usually the kind that hackernews complains about. "Microsoft pushes mandatory, OPT-OUT windows update that prevents mouse from waking up computer!"

- praptak 4y agoI do believe there was a game which had an easter egg based on this. While the game controls were keyboard-based, it detected the erratic mouse moves to display something like "Don't whack your table!".
- c7DJTLrn 4y agoNow I wonder if mouse movement could be used as a side channel to hear sounds in a room... NSA have probably done it already.
- smilespray 4y agoOr Mordechai Guri, the Israeli dude who specializes in air gap exploits.
- thesuitonym 4y agoThe problem with that solution is most people want their PC to wake up when they wiggle the mouse.
- LegitShady 4y agohe didnt' say it shouldn't wake when it wiggles, he said they change the sensitivity required to wake it.
- tpmx 4y agoIt turns out it's actually pretty easy to distinguish "wiggle the mouse" from "a truck just drove by nearby and triggered a one pixel movement". Microsoft should have quite a few employees that could figure this out.
- leni536 4y agoIt is probably hard to do while the computer is asleep.
- tpmx 4y agoAs I wrote in another comment; it was possible to disable wake from sleep from within Windows for that particular mouse; that was promising. I don't know if it's possible to execute logic on mouse movements in the Windows sleep power state. Either way, I feel it's something MSFT should spend some time on, given the current situation.
- sgtnoodle 4y agoIf there is code running in that low power state, it's likely firmware on a microcontroller somewhere inside the motherboard chipset. Microsoft probably can't do anything to fix that, other than make more robust mouse wakeup a requirement for branding future products as "made for windows". Suspend isn't even usable at all on my desktop when running Linux. The AMD GPU doesn't come back up properly 3 out of 4 times, and then any userspace processes that were using any graphics APIs (such as the desktop environment) are borked. Fixing that would probably save me 1kWh per day. In my experience, I can't even get monitors to power off reliably, and I spend hours and hours fiddling with that sort of thing trying to debug it. Anything power-save related is a mess.
- oakwhiz 4y agoI wish the mouse itself could filter out these movements and refuse to send a wake signal unless the magnitude exceeded a minimum threshold.
- RussianCow 4y agoI think this is exactly what my Logitech M510 does. When the mouse goes to “sleep” after being idle for some time, bumping it very slightly doesn’t seem to do anything; you have to move it about a quarter inch or more for it to wake up. This effectively prevents minor bumps from waking up my PC.
- afandian 4y agoApple too. I have a USB mouse and it's virtually impossible to put my Macbook Pro to sleep. I've resorted to unplugging its power supply (when the lid's closed it won't wake up if it's not plugged in). But you would have thought this was trivial to fix.
- lostlogin 4y agoApple solved this by having the mouse charge port on the bottom. So if the mouse is changing it’s unlikely to trigger as its upside down. However if a fly goes past.
- tpmx 4y agoThis comment makes no sense. However if a fly goes past.
- kelnos 4y agoI believe it should be: "However, if a fly goes past, it can get in the way of the laser (or whatever the mouse uses) and trigger mouse movement."
- tpmx 4y agoOkay. Now please explain "Apple solved this by having the mouse charge port on the bottom."
- lostlogin 4y agoThe mouse won’t randomly move on the table and trigger the sensor, because Apple’s horrible mouse has to be charged upside down, looking like a dead beetle. I hate that mouse. I should have put an ellipsis at the end of my fly comment.
- tpmx 4y agoSo every time you're away from the desk, you put Apple's horrible mouse upside down to charge it and thus this problem is solved? Yeah, I know I'm probably being overly anal here, but, come on. :)
- tyrfing 4y agoThat sounds like a mouse issue, there shouldn't be enough jitter for that to happen. Common reasons would be a dirty sensor or maybe surface incompatibility.
