Got my T450s just two days ago and have the following issues with sleep mode:
1. Fn + F4 does not activate sleep mode
2. Manually selecting sleep mode from Start --> Power results in one of following:
EITHER unable to wake from sleep mode. Pressing keyboard keys (incl Fn), using pointer, etc. none of these will work. Must execute hard shut down and re-start using power key in order to use the laptop. I know it is in sleep mode because the Thinkpad "i" blinks slowly and screen is dark
OR computer screen is black, but Thinkpad "i" is fully lit (implying it isn't in sleep mode) however the computer doesn't react to any typing or Fn to bring it out of sleep mode
Anyone else having these or similar issues? Please advise of any solutions. Have latest Windows 10 update and BIOS. Have fingerprint reader functionality but am not using it.
This is my first Lenovo laptop, bought it for work and many of my coworkers were interested to hear what I think about the product. Don't think I could recommend it to them in all honesty at this point....

Thanks, tried this (my power mgmt driver was v.15 instead of v.20) but have nearly same issue, though recently I've found that after 30 min or so the computer seems to be totally shut down. So I press power button to turn back on instead of hard shut down and then turn on.
