    New Intel drivers 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 ( appears to address the notorious issue of high power consumption during 'sleep' mode.

    As Paul Thurrott reported last month, Microsoft acknowledged the problem and stated that a workaround was a "very hard computer science problem". Surface Pro 4 users have widely reported that during the device's sleep mode, it would continue to consume between 7% to 9% of the battery per hour, forcing users to move into Hibernation mode rather than sleep in order to save battery.

    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.

    To evaluate the driver, we compared a series of two-hour Sleep Study reports from the November driver to the December driver. 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...

    Still waiting for this to show up on 1/19/2016 in Windows Update as suggested it should by some web sites/blogs. It should apply to the Surface Book also if this indeed corrects the battery drain during sleep.
    I've just been shutting down my SP4 instead of sleeping or hibernating. It literally takes 8-9 seconds to boot so the impact is minimally inconvenient.

    Now it's 1/21/2016 and still no update. It's clear the source(s) of this postulated update on 1/19/2016 is(are) not reliable.
