Trouble with sleep on T400

Hi all,


I'm experiencing problem with sleep mode on my T400 - sometimes machine wont enter sleep mode. Last time I was using a computer in Maximum performance ower scheme, and I have, since last startup, turned off wireless adapter by switch on the front side.

After I pushed sleep button, screen was turned off, but the sleep mode was not reached - I also could not use computer any more, i've tried pushing all the buttons, but nothing happened.

I've explored system log, and it seems that wireless service, NETw5v32 was causing the problem - I have large amount of events with the following description in my log:

The description for Event ID 5005 from source NETw5v32 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

These events were written to log during the time my machine was unresponsive.

Are there amy similar experiences?

Many thanks in advance,

Kind regards,

So far, sleep mode is working fine.
