Looks like new Intel drivers will help a lot! Go get it!

New Intel drivers appear to solve Surface Pro 4 sleep power consumption issue

Users of the Surface Pro 4 may get some relief today as Intel's latest driver update (15.40.14.32.4352) appears to address the notorious issue of high power consumption during 'sleep' mode.

While Intel's last driver was released at the end of December, it has not been made available to Surface Pro 4 users, nor will its normal installer allow owners of the device to apply it as it has not been validated by Microsoft. However, users can download the ZIP file, extract it and then install it normally from Device Manager.

Where the November driver would consume over 2000mW during the test, the new driver uses a relatively meager 625mW during the same time:





Previous drivers showed multiple Intel devices being active 100% of the time during sleep. The new drivers appear to address this.

Kinda looking forward to taming the sleep-beast. While hibernating isn't exactly tortuous to me, sleep mode is designed to be the native approach to the Surface Pro experience. I'll go back to it (sleep, instead of hibernate) as soon as it works a bit more as intended.

Thanks for the heads up!!!

Will this fix the deep sleep issue where it just won't come out of sleep without doing a soft reset?

Hmmm, I downloaded and unzipped the files, but when I point to the folder to update my drivers, Windows tells me the best drivers are already installed and does not give me the option to proceed. I tried uninstalling the existing drivers, but it automatically reinstalled them.

Just wait for Windows Update don't put in non-matched drivers

You have to force it by saying you have a disk and then navigating to the dll

I don't see how you manually install them on the surface 4 pro, but I notice that they are dated dec 22nd, not anything near mid Jan.

 

[SteVae]

the best way to install them is to go the "i have a disk" mode. and even then you have to make sure you install the right file. it isn't easy as these computers are well protected. but, i unplugged mine last night at 12:14 am, and checked it again today at 12:43 pm, and it had 87% battery left. that is every so slightly over 1% per hour, which is ten times better than the 8% per hour i was previously losing. so i think it is worth a little work on your part. jmho.

i just installed the new driver and set the SP4 back to default sleep

 

[jrhurley]

just installed this new driver then reset sleep settings back to defaults. put the SP4 to sleep and waited for an hour and then came back and took it out of sleep and battery was at 100%.

that is good news

Is WiFi auto connecting when it comes back out of sleep, or, do you have wifi enabled while asleep ? Very curious to know the results you got based on that!

 

[jrhurley]

i have wifi turned on while it is sleeping it did shift to my 2.4 ghz network when it woke back up when i had it on the 5 ghz network

will have to play with that a bit since about 2.04 pm today with just posting here and doing a minimal amount of browsing theSP4 went from 100% to 85% without this updated driver i would have been well,past 60%


will see how it goes. i did switch back to 5ghz network

 

[jrhurley]

since my last post i have been playing an online poker game for fun and at this time my battery is at 56% with 2.5 hours left

 

[jrhurley]

ok it is 8:25 pm and i just picked up the SP4 since my last post. the battery is at 53% so in just about 2.5 hours it lost 3% of battery a vast improvement over the old driver

 

[billyboyblue]

My SP4 was working fine, then after installing these drivers, i started getting the display drivers stopped working and were recovered, etc. Seems like a step in the wrong direction to me.

 

[jrhurley]

Ok left the SP4 on the charger till 9:30 pm last night. IT had 100% charge and I just turned it on at 9:10 am this morning and I have 91% charge. All the sleep settings were at the original factory defaults so this looks good for the charge issue.

I have not experienced the display drivers stopping issue on my SP4 which is an i7 16GB 512 unit.

my driver details are:

Intel Corp
12/15/2015
ver 20.19.15.4352

Intel Iris Graphics 540

I do not see any events yet in the logs for this driver but I will watch and let you know if I see anything.
fyi
I did the manual install which is the only way to install these drivers at this time.

 

[billyboyblue]

haven't had anymore crashes since the first install

 

[yaoye78]

unfortunately it doesn't help my i5 pro 4 (intel 520). Still as inconsistent as ever

 

[billyboyblue]

I don't think you're on the latest still. The latest drivers for Gen 6 intels ( including yours ) should be from 12/22/15 based on the intel website. Have you had a look to confirm that ?

DRIVER VERSION: 15.40.14.64.4352 & 15.40.14.32.4352
