    waking from sleep after 8.1 upgrade

    I just bought a Lenovo U330 Touch which shipped with Windows 8. I upgraded to 8.1 and immediately things began to go wrong! Many drivers needed replacing but as they were well signposted it was a pain but not a disaster. What really hurt was the murder of the wake from sleep functionality. There is currently no way of waking the computer up from sleep mode other than a hard switch off and restart. Looking at the Lenovo web site, I can't afford to use their premium rate number for tech support!, it seems that I am not alone with this issue. I phoned Microsoft but after a tech remotely looked through my machine he gave up, promised to escalate the issue and said I would get a phone back within two hours. That has not happened so I assume Microsoft are as stumped as I am. I wonder if you can throw any light on this.

    Have you tried...
    Power troubleshooter; Open control panel, type "troubleshooter" in search box, click "troubleshooting".
    Click on "improve power usage" under Sytem and Security.
    It should look like this

    You can also try this...
    Copy and paste "powercfg -ENERGY", without the quotes, into an elevated command prompt.
    It'll take a few minutes to run. Note where the html report file is located.

    There have also been reports of networking causing such sleep/wake issues as well.
    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.
