T410 sleep facility

2011-11-15, 22:55 PM

After working fine for a year, the sleep facility on my T410 has ceased working.  I have checked settings and all appears to be correct.  Until recently, when I close the lid the sleep symbol (green light visible at the top of the lid) would light up to signify that the system had entered sleep mode.  Now it does not.  I have run full system diagnostics - all correct.  Can anyone suggest what I need to do to fix this?

To go event viewer, you can go the contorl panel->system and security->administrative tools , but the fastest way is still as shown. Anyway, it's cryptic and not easy to find what you see.

 

 

My guess is that there is something interrupting the sleep (take a sedative B-)....some programs running or something.wrong with the hibernation file. Try to delete the hibernation.sys, then see if the fresh one have the same problem.

Have you updated your Power Manager recently? Was one of the power profile changed so that it won't react to lid closing event?

Does it sleep normally if you tell it to sleep from the start menu or through pressing the keys to make it sleep? Will it hibernate? My T400 recenltly decided to not sleep and I haven't figured out why yet.

Sometimes it does and sometimes it does not.  From the start menu it seems to go to sleep - but the green crescent moon symbol does not light up. Pressing the on/off key has the same effect but occassionally the system will, after a few seconds, wake up again.  The only certainty is that opening the lid will wake it up.  Thanks for your interest in this  // BBL

No - power management options have not been changed and still show sleep on lid closing.  Thanks for interest, // BBL

Thanks for this.  The EVENT viewer did not help at all but you parting comment about a piece of software holding up the standby mode proved to be correct.  Software driving an external harddrive that takes constant backup was obsolete and was hanging the standby.  Update of this software solved the problem.

Another common cause of computer insomnia is the wireless mouse.  I've had two desktops and a laptop that would wake up from sleep unexpectedly, at random times.  This not only increased power consumption but was also taking useful life off the hard disc drive and cooling fan.

 

The simple solution for computer insomnia is often as follows:

 

1.  Open Device Manager

2.  Click on Mice and Other Pointing Devices

3.  Select the Power Management tab

4.  UNcheck the box for "Allow this device to wake up the computer"

5.  Click OK and close Device Manager

 

Just a little thing to help make your computer take its naps as instructed.  Unfortunately, it doesn't work with kids.
