Anyone with a Lenovo Laptop (T60/T61) Please try this

I have been experiencing a problem which I think is more widespread than Lenovo knows. Techsupport denies the problem exists and claims it is my fault. Other users are experiencing this problem too.

I believe it is a driver problem.

Please try the following to help us diagnose the problem and browbeat Lenovo into making their machines work.

0) Unplug from power source
1) open an application that utilizes the sound (such as a flash animation in a webpage, a youtube window, windows media player)
2) play the application
3) close laptop whilst the application is playing your media (sleep)
4) wait for the little crescent moon light to come on (sleep)
5) open laptop
6) log in
7) the sound will not be working
8) Either kill the application that was utilizing the sound or plug in the laptop to an external power source
9) sound will magically come on

Call Lenovo and complain

Never had a problem with this. I will double check later, however I normally just close the lid with stuff running and open it back up still on battery power.

 

Do you have another, non-Thinkpad to try this on with same operating system?

Otherwise, might try asking in hardware forum to see whether non-Thinkpad users can reproduce this as well. Might be Windows' fault (driver, software, etc) rather than Lenovo's.

 

I Believe the problem is caused by the lenovo powermanagement software/drivers.

The operating system is vista (vista image came with the machine).

A friend owns a T60p just like mine and he does not have problems with this issue (he's running uBuntu).

I have not had the opportunity to try another Vista laptop.

 

I just tried it and the sound and everything is fine

 

That may be a problem with Vista. It is a known bug that high definition sound might now work after returning from sleep. Can be fixed with a patch (search Microsoft).

 

I've just installed the 'fix' for this issue and it still doesn't appear to work.

Additional note. To reproduce &test the problem it may take one or two sleep cycles (with the laptop unplugged). I suggest playing youtube video, shutting the computer, opening the computer and logging in.

 

Hmm...maybe it's just an isolated issue. There might be more than one fix.

 

My T61 is currently down for the count-but I do recall having some issues like this.

I can't say whether the situation was exactly the same. But I recall there were repeated times when the audio wouldn't work, and I couldn't figure out why. I'd eventually just restart. Now that I think about it might have been on battery and after coming back from sleep mode. Can't say for sure.

 

Ok... i just installed every single update available through the thinkvantage updater tool.

including... powermanagement drivers, bios updates... etc

No dice. Still not working.

Sillyone, hit me back when you get it to work. Try going through these steps:

1) unplug
2) open a youtube video in firefox(my browser of choice)
3) sleep
4) log back in
5) check if the audio is working
6) if not either plug in or kill firefox with the Task manager.

 

Forget about those step, open the control panel and go for the sound applet. In my T61 running XP, sometimes pressing the volume increase and decrease volume will magically mute the sound. This won't show up anywhere on the applicaition, but if you go to the sound applet you will see that it has been mute, just turn it on.

At first I suspect it was the power manager too, but i recently come to think that it was the hotkey driver....try uninstalling that one and see if the symtom still occurs.
