Got a strange problem with my T500 that started after I upgraded to Windows 10. It wakes from sleep when I open the lid, but then after showing the lock screen for a few seconds it goes back to sleep again. No amount of key pressing or mouse action will stop this from happening. Once back to sleep I can wake it for good by pressing the Fn key and everything is fine. Doesn't matter how long it's been asleep for. Hybrid sleep and Hibernate are both off. Got a T410s also running Windows 10 and same settings but this wakes up fine. Anyone else experienced this ?

OK I spoke too soon - the problem is back. Think I might need to start a new thread as not sure how to unmark as solved. Have also discovered that it's not just lid open waking that does it....if I put the laptop to sleep using the F4 key it still needs 2 attempts to wake up. Have also noticed that on first attempt no sound is made, but on the second, successful attempt, I get the Windows "Device Disconnect" sound.
