T61 Bug

My office T61 Lenovo runs Win XP Pro.When I shut the lid of my laptop it automatically hibernates and when I bring that lid back up it automatically wakes up.But the problem is every time the laptop wakes up like this there is no sound and I had to restart all over again

Apparently it is a bug and there are a couple of ways to fix it. 1) Disable/Enable your sound device 2)Uncheck “allow this device to bring the computer out of standby” from the Power Management properties of your software modem 3)If you don't use your software modem at all just disable it.

All I got from http://www.paralaptop.com/lenovo-laptops/fix-sound-bux-on-thinkpad-t61-after-standby.html but just blogged it on my own blog in case I forget this 6 months from now and start looking for it all over again.

The link never explained what exactly the bug was but made it sound it was some sort of a hardware conflict.I did not find any other material about it on the inter tubes.
