I have done a clean install of Windows 7 Homepremium and my battery life on my Vaio TX3 has gone from 6.5 Hours to only 3 hours. I cant find the power management drivers. Also I can no longer use the keyboard hot keys to adjust the screen brightness.

View 1 Replies View Relatedso i am not intirerly sure this is the correct place to post it.Secondly, i think this is a problem that i have created myself and now i am unable to correct it.The jist of it is this. Whenever i try to active the webcam (Function + F10) a pop-up shows saying that hardware connected to a USB port is not recognized. This must be cause by the cam (which us buillt-in) is connected to the USB port on the motherboard.When i go to device manager, i can see that there is a unknown device connected, whenever the webcam is powered on.Btw it worked fine when i did the initial installation of the computer.What i have tried to do to resolve this is the following:
- Remove all drivers asociated with the webcam - reboot - reinstall from provided CD
- Power down, take out batteri (even for en entire night) to let the motherboard reload the USB drivers.
- Removed all the USB drivers and have tried reinstallling
I deleted som folders from my D: drive, (which is not the partition that has my windows directory installed) and there i might have deleted som crutial files for the webcam software to work.I have no idea on how to go on from here. This is a computer i have spend quite a long time getting up-2-date with all the programs i use for school and the exams are coming up. I would really like not having to do a clean install right now.
I have installed Windows 7, on my Vaio VGN-SZ660N and I`m having lots of difficulties with installing its new drivers.I can not install Windows Shared Library, So My Function keys do not work any more and more important I do not have my "Battery Care Function" any more which resulted in damage of my battery.where I can get "working drivers" for my Model? Because the ones on the Sony website do not seem to be working...

The Windows 7 is to much for the computer?What drives can i use?
I have just installed Windows 7 64bit version.
My computer is a Sony Vaio VGN-NS11J from the EU.
Intel Core 2 Duo - T5800 2GHz
4GB Ram
290GB HDD SATA
Mobile Intel 4 Series Express Chipset Graphics Card
I have 2 drivers which I cant find drivers for - 1 of which I believe is a Texas Instruments SD Card Controller.
The details I can glean from Device Manager are as follows:
1st:
Base System Device
Location: PCI Bus 5, device 3, function 2
Physical Device Object Name: DeviceNTPNP_PCI0023
2nd:
Unknown Device
Location: on Intel ICH9M LPC Interface controller - 2919

I have a sony vaio vgn-sz430n running Windows Vista Business. I upgraded to Windows 7 and it went off without a hitch until the first log in. The desktop will not fill the screen and it only gives me two options for resolutions: ~1024x768 and 800x600. I went to device manager and found that my display driver is now standard vga driver.
The laptop has an nvidia geforce go 7400 graphics card and, from what I've read, it also shares memory with onboard integrated graphics...I think. I read other threads suggesting methods to fix this problem but none of them have worked. I tried downloading the windows 7/vista driver for that nvidia graphics card from nvidia but the setup program says no compatible hardware found.
I tried pointing Windows 7's driver installation (from device manager) to the driver's location in the setup folder but it tells me the most current driver is already installed and no update is needed. I even tried modding the driver (as suggested on another thread) but that didn't work.
It's a Sony VGN-NW265F/(B???) (Idk what the difference between the F and F/B is but on my laptop it is listed as just VGN-NW265F..I do have the Blu-ray player option though is that what the B stands for?) anyways
Device Manager is showing:
Base System Device
Device type: Other Devices
Manufacturer: Unknown
Location: PCI bus 11, device 3, function 2
Device status
The drivers for this device are not installed. (Code 28)
To find a driver for this device, click Update Driver.
the function keys do not work anymore after windows 7 was installed.
is there someone with same problem solved?
How I installed the latest Nvidia M 186.81 notebook driver to my Sony Vaio VGN-AR51E laptop. Sony is supposed to supply the drivers but they don't for some reason.
The latest laptop drivers from Nvidia work if you alter two lines of information in the appropriate inf file before executing. I downloaded the latest driver from Nvidia (186.81) and ran it so it unpacked into a folder in my C drive. [Message box says it won't install].
From Control panel I got my driver hardware ID
Control panel / Device manager / Display adapters / Properties / Details / Device description/
PCIVEN_10DE&DEV_0426&SUBSYS_9016104D&REV_A1
PCIVEN_10DE&DEV_0426&SUBSYS_9016104D
PCIVEN_10DE&DEV_0426&CC_030000
PCIVEN_10DE&DEV_0426&CC_0300
(You just need the second line here)
Then I opened up the Nvidia driver package and altered NVDM.inf file, in the Display folder, by adding two lines to include my hardware ID
(as you scroll down the inf file and study, you will see where these go, in two different list sections)
%NVIDIA_DEV.0426.01% = Section005, PCIVEN_10DE&DEV_0426&SUBSYS_9016104D
NVIDIA_DEV.0426.01 = "NVIDIA GeForce 8400M GT (Sony Vaio AR51E)"
I included my ID also in ListDevices.txt in the NVDM.inf section
and in modes.txt (but may be superfluous - I am no expert!)
Also I put the two lines in the NVAM.inf (but may be superfluous)
Don't forget to save all.
I deleted the old Nvidia driver rebooted and ran setup on the new Nvidia driver! It worked!! Hope this helps you. PYL
