I perform a similar test. Since the 1st Jan firmware update, this is what I have found:
SP2 (with Dec failed firmware)
- Prior to the Jan firmware and after Dec failed firmware, consistently able to replicate an auto wake problem.
- After 1st Jan firmware, immediately observe the auto wake problem fixed. Has yet to be a problem after several days.
- However, since 1st Jan firmware have experienced incorrect battery "Full Charge Capacity" value one time.
- At that same time observed a 2nd Jan firmware update. Loaded it, but no correction to Full Charge Capacity. Performed up volume + power button reset to reset value.
- Have tested about 15 sleep tests, >10 sleep to hibernate. Ok so far. No idea if this has any correlation to 2nd Jan firmware.
- Confidence somewhat shaken. Still testing.
SP2 (no Dec failed firmware)
- Observed 3 Jan firmware updates over a series of days.
- Note, this SP2 has not shown any issues after loading Oct updates. Did not experience Dec update.
- 1st Jan firmware update appeared to work ok.
- After 2nd, had occasional crashes upon wake. It appears the crash is related to hibernation.
- After 3rd, tests show it wakes normally from sleep-hibernate.
- Still testing. Confidence shaken.
When you say sleep test - how are you putting it to sleep? Are you letting it timeout and go to sleep and then timeout to hibernate or are you initiating the sleep by some method such as from the Charm Settings-Power-Sleep or may be you have configured
the close touch cover to initiate a sleep. Also is this on battery or powered?
If I try to make mine sleep by timing out, then the display goes off but it doesn't enter sleep mode (If I specifically put it in sleep mode it works but doesn't timeout to sleep mode) If it is really in sleep mode it won't wake up if you touch the screen
other than on the windows icon at the bottom centre.
If yours does timeout to sleep I would be interested to know what setting you are using Thanks
