This total ignorance and inability from what I thought was THE premium business notebook-maker regarding both quality and support, is below my expectations by a good margin.
It seems that at the end of the day Lenovo is nowdays not unlike any other massproducing consumer oriented notebook maker. Only overpriced and often with a lesser performance than it's competitiors.
You can't continue devaluate the Thinkpad-brand forever without custumers taking notice.
Fool me once...

Only the workaround to switch from integrated to dedicated and back again seems to be able to fix the issue in my case.
As I read, I see that another ATI driver seems to fix the issue, is that correct ?
At this point of time, no fixed hybrid driver is published by the driver site (I signed up for the RSS for the T400) :-/
Any help is much appreciated !

We've just released new drivers and they can be downloaded on the following links. These are for Windows 7, 32 and 64 bit and are appropriates for the switchable graphics eqipped models of R400/T400/T500/W500.
I am interested in feedback on these to confirm they resolve the power management concerns after resuming from suspend, and they should also ensure the on screen brightness feature works correctly.
- Fixed an issue where the power consumption increased after resuming normal
operation from sleep state.
- Fixed an issue where the LCD had blank screen after resuming normal operation
from sleep state by opening the lid.
UPDATE: I'm moving all the feedback on the new drivers to a new thread because the original issue has been solved by the drivers linked here. We need to collect feedback on new symptoms and pursue resolution for those.

Thanks for posting the update. I'm sure several of us find this really useful. We'll give it a try and check if the problem is solved.

Thank you for the update!
On my machine (276552G) it works properly: when waking up from sleep in integrated graphics mode the GPU of the dedicated graphics is active for a few second but then shuts down.
The screen brightness feature works fine.
