First, i perfer vista to 7 on my T60 due to the 1024x768 screen, vista seems more suited for it. Second, i like having vista on it to show off how decent the OS actually is, since most people dismissed it as windows ME the second. Also this is my first guide type post ever. so sorry if it seems a bit badly written in spots.
Now for the guide
Before you do anything make sure you have a USB stick with Autopatcher for vista on it,
thinkvantage system update on it as well. This will make the setup a lot easier. Make sure you include the intel INF update utuility it makes it a lot easier on you to have that. Also if needed include vista SP1 and SP2 on the USB stick as well as the optimized GMA950 drivers from
http://forum.9xxssf.info/ they do improve performance.
Now, when setting up vista make sure you have the right SATA drivers, if it has trouble detecting your drives just put the drivers on the USB stick and use that. I have had this issue with Vista RTM on a dell with a ICH8M SATA chipset, the T60 uses a ICH7M.
Upon finishing the install of the operating system, Install the latest Intel INF installer driver and the video driver, reboot. Now run autopatcher only after you confirm you have SP2 installed. Let it go to work installing everything. After those updates are done, connect the thinkpad to the internet now that you have most security updates installed. Install thinkvantage system update and let it go to work.
Now comes the fun part, tweaking vista. after you have everything updated and all the drivers installed, open the intel graphics properites and go to the power manager, set it to either off or minimum so you can use aero with no performance penalty, second go to 3d settings and tell it to use high memory footprint. That will let it use the full 256mb that Vista/7 allow the GMA950 to use (xp is limited to 224mb, small advantage to vista/7). Now i disable windows firewall, windows defender and UAC for annoyance and performance reasons (at least iwth defender) another tweak, if you do not do many hard drive searches, turn off the indexing service, as well as the spooler service if you never do anything printer related, even create PDF's. Finally double check your hard drive to make sure advance performance is enabled, if not enable it.
With these tweaks your T60 will be able to run vista, and even 7 perfectly, i feel vista is as fast as Xp for the most part.
Other reccomendations:
Ram, Max it out at 3 GB...no reason not to
CPU: stick with Xp if you have a Core solo...vista may lag quite a bit on it.
Hard drive: be aware that vista uses more HDD space than xp. My 60gb is somewhat cramped with vista on it. Also, 7200RPM drives are a decent idea to have with vista/7 to cheaply increase performance.
my system with firefox,AIm,MSN,MIRC,Yahoo,Vista Aero fully enabled only uses about 50% of my physical memory with 75 processes. and it is still pretty fast even at that state
Sorry if any info here was repeated, but is saw several xp guides and 7 guides on the internet and felt that vista deserved to be remembered.
