I am trying to format sony vaio pcg-c1mrx in command prompt but i dont know what the command to enter. please help me how to do this. thanks!

This can be usually done by a Windows Password Tool. However, if you have already activated the Administrator on the PC (Any Brand) with Windows 7. You can try the following steps.

Generally, the logon does not have the administration account listed. So one may want to go restart the machine to the Command Prompt to enable the Command Prompt.

Restart the Machine --> Tap F8 (Advanced boot options) --> Go Save Mode With Command Prompt --> Command Prompt Window appears. Type :
1: net user Administrator /active: yes
2: shutdown -r

This would restart the machine and the Windows Logon will have the Administration account. You can login to the Administration Account and then change the password on the other account.

Also, If you do not have the the admin account activated, then you may want to get windows key from http://www.lostwindowspassword.com/windows-password-recovery.htm

(This is a paid software).

You may get several free software's online as well.

bootable USB guide, here we assume that you are using either Vista or Windows 7 to create a bootable USB.
1. Insert your USB (4GB+ preferable) stick to the system and backup all the data from the USB as we are going to format the USB to make it as bootable.
2. Open elevated Command Prompt. To do this, type in CMD in Start menu search field and hit Ctrl + Shift + Enter. Alternatively, navigate to Start > All programs >Accessories > right click on Command Prompt and select run as administrator.
3. When the Command Prompt opens, enter the following command:
DISKPART and hit enter.
LIST DISK and hit enter.
Once you enter the LIST DISK command, it will show the disk number of your USB drive. In the below image my USB drive disk no is Disk 1.
4. In this step you need to enter all the below commands one by one and hit enter. As these commands are self explanatory, you can easily guess what these commands do.
SELECT DISK 1 (Replace DISK 1 with your disk number)
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
(Format process may take few seconds)
ASSIGN
EXIT
Don't close the command prompt as we need to execute one more command at the next step. Just minimize it.
5. Insert your Windows DVD in the optical drive and note down the drive letter of the optical drive and USB media. Here I use "D" as my optical (DVD) drive letter and "H" as my USB drive letter.
6. Go back to command prompt and execute the following commands:
D:CD BOOT and hit enter. Where "D" is your DVD drive letter.
CD BOOT and hit enter to see the below message.
BOOTSECT.EXE/NT60 H:
(Where "H" is your USB drive letter)
7. Copy Windows DVD contents to USB.
You are done with your bootable USB. You can now use this bootable USB as bootable DVD on any computer that comes with USB boot feature (most of the current motherboards support this feature).
Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.

Clean Install Windows on a Sony Vaio

Even if a Windows operating system is already installed on your Sony Vaio, it is possible to clean install the same version again or clean install an upgraded version of the Windows operating system over the current operating system.
A clean install of a Windows operating system overwrites the Sony Vaio's current operating system and cleans the hard drive by automatically deleting all of the applications, files and settings that are stored on the Vaio.

Create recovery discs for your Sony Vaio using the Vaio's built-in VAIO Recovery Wizard.
Access Vaio Recovery Wizard by going to the "Start" menu and clicking "Help and Support." Follow the screens in the VAIO Recovery Wizard to make recovery CDs for your computer.
Transfer files and programs that you want to save onto an external storage device, such as an external hard drive or a CD.
To transfer the files and programs to an external hard drive, plug the external hard drive into a USB port on the computer and drag and drop files from the computer into the external drive window.
To transfer the files and programs to CD, open a CD-burning software and choose the "Data Disc" option, upload all of the files into the program and "Burn" or "Write" them to the disc.


Place the Windows installation CD or DVD into the disc drive of your Sony Vaio.
If the computer is already on, reboot the computer.
If not, turn the computer on to boot the installation disc.

Follow the onscreen prompts to go through the installation wizard for the Windows operating system.
Enter the product key from the Windows operating system packaging, accept the terms of the operating system license and, if prompted to choose a type of partition for the Sony Vaio, select "NTFS."
Click the "Install Now" button on the last page of the installation wizard.
The operating system installs to the Sony Vaio.

Wait for the installation of the operating system to complete, which can take up to two hours on some systems.
Once the installation is finished, reboot the Sony Vaio and the computer should boot up to the operating system screen.

I have the same problem, It works at an external display and the lcd and lcd cable work on another laptop.
The problem is that i have a sony vaio and it has no inverter, or at least i dont see one like an hp laptop for example. i tried to switch image from external monitor to lcd and it doesnt work. i tried everything. dont know what to do more, Hope you can help.
I have a Sony Vaio pcg-61813M.
Thanks.

open command prompt and type shutdown then hit space button then -r then hit enter button your laptop will reboot

Boot from the "System Restore" CD-ROM.
One of the "setup" options for XP (or for Vista) is to "format" the entire disk-space, before continuing with the re-install.

Is it VGN-NR310E/S?
if so go to:
http://esupport.sony.com/US/perl/swu-list.pl?mdl=VGNNR310ES&LOC=3

All the drivers for XP as well as Vista Home Premium are there.

Hope this helps.

If you will turn your VAIO upside down you will see reset button. You can press that with pin,. This will reset camera. Reinstall camera drivers after reset and camera should work.

You can try using and typing :" driver VAIO PCG-GR300P " ( ex: using : google search ) there is many alternative web to dowlnload driver for you
