Hi, I recently bought a Sony vaio vgn-NW11s/s and I`m loving the laptop.
Right now, Vista (home premium) is working fine for me (it didnt on my last laptop) but I am going to order the windows 7 upgrade very soon. I dont think I will install it straight away as I would rather let a few bugs be ironed out first but I have a few questions.
1. Can I delay my installation to when suits me.
2. Will I discover any problems with the laptops standard spec, graphics card etc.
3. Will all my vista running software work fine and pre-installed software.
4. Do I need to ensure my vista has all the latest updates and is this relevant to the download if I do an "in place" upgrade.
5. Is the "in place" upgrade the best way to go forward. I`ve just got all my software and pictures etc back on this new machine so I do not want to go through that again!
5. On the upgrade pages it says that it does not include windows mail (which I use)and outlook express. Does this mean I will lose windows mail? or does this only happen if I do a clean install.
Thanks. 
Hi Rodney123 and welcome to Club Vaio.
The Sony Windows 7 Upgrade Kit comes with all the drivers etc to make sure everything works with Windows 7 the same as it does for Vista.
Sony only offer an Upgrade In-Place so you will keep all Software, Updates, Data, Settings exactly as you have set up Vista.
1. You can delay the installation until it suits you but you must have ordered your Sony Upgrade Kit before the cut-off deadline of 31 January 2010. You may as well order it now as no upgrades will be done to the kit in the future.
2. No
3. Some older software will not run on Windows 7. I recommend you run the Windows 7 Update Compatibility Advisor and it will tell you if any software will not work. Outlook Express is one of the programs that won't work.
4. Yes, Vista must be fully patched before you upgrade.
5. Windows Live Mail can be downloaded and works OK. Outlook will not work.
The Upgrade Kit removes the Recovery Partition as part of the upgrade process. Make sure you burn at least two sets of Recovery Discs and verify they are OK.

EDIT: Sorry I didn't realise you had two 5's!
5. Yes, an Upgrade in Place will retain all your programs and data.

I have a NW11Z/T which has 4gb of ram which yours also has, and sonys upgrade kit will be a 32bit opertaing system only. Before i ordered the kit i test installed the 32bit version of windows 7 very thing worked except my vaio recognised less then 3gb of ram, which i found abit annoying so i purcashed a 64bit windows 7 from microsoft instead. All the new NW models comes with windows 7 64bit operating system so there is pleny of support.

You passed the test!

Will the 64 bit edition work on a NW11S/s?

All I am doing is urging you to think about it carefully.
Hi Oterias,
after installing windows 7 my bluetooth worked fine without me doing anything and had no problem with SFEP drivers...
Things I installed are:
Sony Setting Utilities
Sony Event Service
Sony Shared libary
Chipset drivers
Also installed the Memory Card and SD card Drivers..
I had a UNKNOWN DEVICE which i managed to download from the american website
It was the Original - Sony® Firmware Extension Parser Device Driver.
Also managed to get the the Alps pointing device, camera software from the too.
Yep i had the screen dimming problem to, all i did was go to power settings and changed the setting so it will not dim at all.
