Updated T400 UltraNav driver (w/ Hotkey update) and Power/Sleep-Key on Dock problem

2010-08-29, 18:43 PM

My equipment:
    ThinkPad T400, Model 7417CTO, 3GB Ram
    OS: Win 7, Ultimate
    Docking Station: Model 2504 (manufacture Date 06/07)
My problem:    
    I have had several instances in the past week, (since 8/20/2010) where my Mouse Wheel and Left Mouse Key quit working.
    Other symptoms include Left Mouse Key either stops working or acts erractic, such as spawning another instance of FireFox when clicked in a FireFox window.
    The Power/Sleep-Key button on the Docking station no longer works to go into the Sleep mode.
    I can now only put it in the Sleep mode, when the T400 is in the Dock, by using the Win 7 Menu selection for Sleep.
    The button on the Docking station still works to Start up and to bring the T400 out of Sleep.
    All these problems occur while the T400 is in the Dock Station.
    I can only get these symptoms to stop by Restarting the T400.
Recent Changes:
    On 8/20/2010 I updated several drivers, including the new BIOS dated 9 Aug 2010, Ver 3.19/3.17.
    I updated the Hotkey driver V 3.10.000, as demanded by the update for the UltraNav driver.
    I updated the UltraNav driver, V, dated 15 Jul 2010.
Can I go back to the previous UltraNav driver?    
Any suggestions of How To Correct this problem is appreciated.

Also look here. I didn't try it yet, but it is suggested to switch to the stock synaptics driver from their website... However Lenovo should issue a bug release of their UltraNav software as well....
