[B] Sleep battery power drain


#21

Systems with CS will only have that one power plan. You need to disable CS to reveal the rest.

Alternatively, you can disable CS, make a new custom power plan based on the other power plans, and re-enable CS afterwards.

EDIT: CS stands for Connected Standby (which is also called InstantGo, or Modern Standby, because Microsoft can never make up their mind when it comes to naming.)


#22

and CS in this sentence means?


#24

ah gotcha, well i have disabled that almost instantly. HAven’t really had time to check my battery life yet. V has been pretty much connected to AC 24/7 at the moment


#25

Ah sorry. That explains it. I had disabled connected standby.


#26

Been trying out LP S0 (aka connected standby) back on these past couple of days and battery life has been good! I did this because I was getting a little frustrated with the slower boot up time/ wake up from sleep time when it was turned off.

So far losing a few percent at most to connected standby seems to be a price worth paying for quick launch


#27

How much of a delay are you experiencing?


#28

Mine died in my sleeve. I think they need to work out some of the battery drain and sleep state issues.


#29

Did you turn off the LP S0?


#30

I didn’t time it, but from sleep maybe 2 or 3 secs rather than 1ish with LPS0 enabled. I know it doesn’t sound long, but it was long enough to question whether the button had registered if you get my meaning.


#31

Not yet. I want to wait for an official update fix. That probably seems strange.

While the battery drain take more than 70% from my V I use it on campus so there’s always a port.

I may do it if I get significantly bothered. I think I’ll resort to full shutdowns while moving it around.


#32

What kind of campus are you on? Mine has plenty of ports, but I’ve got to sit in the floor in a hallway if I want to use one :joy:

That’s why I really want something to last me all day, I hate how my Surface almost makes it through my day, but halfway through my last lecture it dies and I’m missing those important notes.

Saint Louis University.

I also work at the IT desk here and i literally sit next to 8 outlets.

I’m with you tho. I don’t want to have to sit next to an outlet because my device drained to 0% while not being used. Team will fix it with emdoor eventually. Just a matter of when.

I ran powercfg /sleepdiagnostics today after a nights sleep, and unchecking “allow this device to wake the computer from sleep” on everything so “powercfg /devicequery wake_armed” returns “NONE”. Still my V kept going back and forth between modern standby and active all night long, never sleeping for much more then five minutes at a time, draining the battery from full to aproximately 33%. The exit condition from standby was “input mouse” and “This session contains no detailed information about top offenders.”. As mentioned “powercfg /devicequery wake_armed” returns “NONE”. Any tips on what is happening here?

I don’t want to disable modern standby as that feels like slapping a band aid on a broken leg.


#35

I disabled CS using the BIOS method (not registry), and I got 0.4 - 0.5% drain per hour, that roughly translates to 0.2 - 0.25 W per hour, where it should really be much lower than that. Per MS document mentioned above, this is not acceptable even for a CS-enabled device.

My finding here shows that there is an issue deeper than CS itself (not saying there is no issue with CS)


#36

Is the drain similar when disabled via registry?


#37

I’ve had this wakeup issue with my desktop computer. It used to independently start at odd hours. I tried finding a reason for this behaviour, but it didn’t seem to be that common issue last year or so. There is nothing to wake it up.

I reinstalled Windows, but that didn’t stop the behaviour. It seemed to start after a Windows Update maybe something like a year ago, but which one it was, no idea.

Currently I have my desktop computer switched off from the mains with a separate switch. But I thought that I’d give it another try and the PC started by itself again on Sunday evening. Why? No idea.

This behaviour seems to affect just some PCs. I am curious about the causes for it. But from my experience it seems that Windows is the main culprit and something in the PC setup or hardware/software the lesser one.


#38

In my case it seems like there is a discrepancy between what powercfg reports and what config windows is actually using. As mentioned I have disabled waking for everything, but my mouse still wakes up the computer from sleep by moving it around.

I put my V into my bag at 100% yesterday evening and carry it to some event Russell Peters’ Deported World Tour Live in Malaysia and when I arrived home at 12am, to my surprised, there has been a close-to-30% drain on my battery. Upon checking the powercfg battery history, it says at 18:23 (around the time I left the house), it was on ACTIVE, all the way until I came home at around 00:11.

Putting it on a test before I go to bed, I ensure I closed the lid nicely, and woke up after 8 hours of sleep with only 3% drain.

Is the keyboard lid THAT sensitive, or there’s something I have been missing?


#40

I’ve noticed a few records where the V goes to sleep and wakes up again <20 seconds later. It seems like:

  • magnet (that triggers sleep)
  • the trackpad
  • the keyboard itself

one of those seems to be waking the V almost immediately after you put it to sleep by closing the lid.

but that’s just my guess because i personally haven’t encountered the drain-in-bag problem, so i havent been able to test if that’s the case.


#41

I’ve had a browse but can’t find anything concrete or a response from eve so

How do I shut my V and the battery not drain?

I have a 2011 macbook that I can shut the lid on, with Photoshop open etc and come back three days or a week later and there is barely any power drain, my android tablet the same.

With the eve it’ll drain over the course of a day :frowning: considering how long it takes to charge to full and that it’s supposed to be a portable with great battery this is just depressing, I’ve done something with LS0 in bios but still it drains

Anyone got a good guide for what should be imho an out of box feature? Or am I expecting too much?
