thinkpad Z61t

[nbf23]

working with Z61t and have basically three issues i am looking to address. i figured i would reach out to the forum before i jump on the phone with lenovo service:

-device manager error under display adapters: mobile intel 945 express chipset familiy & mobile internet 945GM express chipset family. code 37 & code 39 respectively....drivers corrupt or missing & cannot initialize. all attempts to download drivers from lenovo and intel have proved fruitless

-cannot get power manager to recognize hibernation. option under power manager "global power settings"; however, once ticked, the settings do not hold

-last, cannot establish new network connection for VPN, choice is greyed out.

any help greatly appreciated.
