hp dv2419 nvidia geoforce go 6150 vista problems solved

This method can be apply to Compaq HP Pavilion TX1314CA AC
So the main problems is the laptop shutdown/hibernate and sleep and hang....so download and install driver updates doesn't solve the problems,
all you need to do is go to nvidia site and download the latest update by automatically detect your hardware or download by choose your graphic models(say here 6150) and OS(vista).

after clicking the file you download you will fail to install but The Nvidia driver extracts to C:\Nvidia even though it fails to install.
Do the force install:
Right click on my computer and select manage:
From Device Manger,
right click the Video device,choose Update driver
Say "no, not at this time" for connecting to Windows Update

Install from a list of specific location

Don't search I will choose the driver to install

Remove the check from "Compatible Drivers" and click on "Have Disk"

Next...browse to C:\Nvidia
