Re: Windows 7

Hello bneagle! Welcome to the support forums!

 

Download and run the Windows 7 Upgrade Advisor to see if your PC is ready for Windows 7. It scans your hardware, devices, and installed programs for known compatibility issues, gives you guidance on how to resolve potential issues found, and recommends what to do before you upgrade.

 

I would also compare and verify there that there are windows 7 device drivers for all your device listed in your Device Manager. You can find your Lenovo Drivers here.

Thank you for being a part of the Lenovo Family,

Catie

Re: Windows 7

Just to add to what Support Specialist Catie (Lem0nade) has said:

 

In my experience, Windows 7 will run just great on a 2.0 GHz R61 with 3GB memory. It's more than powerful enough.

 

@  bneagle, what is the full 7-digit type/model number on the back of your laptop?

Re: Windows 7

Hi.

 

Information on "7743-W73" doesn't show up when entered in "Quick Path" on the Lenovo Software and Drivers download page. You can double-check that the type/model number you provided is correct. However, I know that there are some models lacking information in the database. Usually you would be able to enter your 7-digit type/model number, and get a summary of your specs.You would also get a corresponding list of machine-specific drivers.

 

Using the information from your first post and considering the specs. of similar machines in "Personal Systems Reference," your approximate specs. should be:

T7300(2GHz Intel Core 2 Duo- 64-bit capable), 1GB RAM (now 3GB), 80GB 5400rpm HD, 14.1in 1440x900 LCD, 128MB nVIDIA Quadro NVS 140M, CDRW/DVD, Intel 802.11abg wireless (3945ABG), Bluetooth, Modem, 1Gb Ethernet, UltraNav, Sec Chip, FPR (Fingerprint Reader), 4-cell Li-Ion battery, WinVista Business. If your R61 came with a webcam, you will also want to install the "Integrated Camera Driver."

 

You mention you have 3GB of memory. As a result, the Windows 7 Upgrade Advisor tool may recommend a 32-bit operating system. However, your Intel Core 2 Duo CPU is 64-bit capable. A 32-bit OS (operating system) can only access ~3GB memory, while a 64-bit OS would be able to access the full 8GB maximum which your R61 is able to accommodate. Although you currently have 3GB of memory installed, let me explain why I think you should install Windows 7 64-bit:

 

Benefits of a Windows 7 64-bit Operating System:

 

(1) 2GB DDR2 RAM modules are relatively inexpensive nowadays, and you can easily replace the 1GB module you have to bring your memory up to 4GB, which Windows 7 64-bit can fully utilize, but Windows 7 32-bit cannot.

 

(2) Even if you stay with 3GB memory, a 64-bit OS can more effectively utilize the 64-bit Intel Core 2 Duo processor your machine has. I recently installed Windows 7 Pro 64-bit on a T60 with 3GB RAM for a relative of mine and the results are impressive. It runs like a champion. I have seen Windows 7 32-bit on a T60 but the 64-bit version just seems to run more efficiently in conjunction with the T7200 (Intel Core 2 Duo 2.0GHz) 64-bit processor.

 

(3) Software conflicts with a 64-bit OS? None nowadays! As I mentioned, I just installed Windows 7 64-bit on a T60 and I have it installed on my W500 (6GB memory). I have not encountered any software conflicts whatsoever. All of the programs, browsers, utilities, etc. which I use are fully compatible with a 64-bit OS. And I run some older programs on my W500 as well. No problems whatsoever! And many modern programs have a 64-bit version to more effectively utilize the 64-bit capability of your processor. IMHO 64-bit Windows, once properly installed, is actually more stable than 32-bit.

 

(4) Future upgrade potential: If you install 32-bit, you are limited to ~3GB memory, although your laptop can take up to 8GB. 3GB may be more than enough to meet your current needs. However, it may not be a year or two from now (as programs just seem to become more sophisticated, more memory hungry, and everything keeps moving towards higher-definition graphics, etc.- all of which calls for more memory). If you install 32-bit and decide to install 4GB or more memory later on, you will have to wipe your drive and start over. (Since it is not possible to do an in-place upgrade from 32-bit to 64-bit). 64-bit Windows 7 looks and feels just like 32-bit Windows 7 except it can access more memory and 64-bit applications can more effectively use the 64-bit capability of your processor. (For example, programs in which higher numeric precision is required, or which process large graphic files constantly). So I really see no benefit to 32-bit in your case.

 

(5) Who knows what the future holds? Imagine you have Windows 7 set up nicely with all of your favorite programs and data, but your R61 conks out tomorrow. (Let's hope not Smiley Happy ). As a result, you wish to utilize that hard drive on another R61, or a T61 which has more than 3GB memory installed. With a few tweaks you would have Windows 7 64-bit up and running beautifully on your new machine and would be able to use all that extra memory. If you had 32-bit installed, you would have limited yourself to ~3GB on a machine that may have 4GB RAM or more to offer. What a waste.

 

I have these scenarios in mind, and that's another reason I installed Windows 7 64-bit on a T60 with only 3GB memory for a relative of mine. If that T60 ever conks out, or if she just wants to upgrade to let's say an R61 or T61, that drive can swap right over (with a few tweaks). And she will be able to utilize any extra memory above 3GB which may be installed on the new machine.

 

BTW, the same Windows 7 key can be used to activate either the 32-bit or 64-bit version. It's your choice.

 

As for R61 drivers, here is an alternate page on the Lenovo website you can use: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&DocID=HT037648. This page lists a few more general driver options than the "Quick Path" I mention above would've listed. You will want to verify the exact specs. of your machine so you can select the correct drivers in case there are a few different drivers listed for a particular hardware category. (For example, Conexant vs. SoundMax audio drivers, Intel vs. nVIDIA video drivers). "Speccy" (by Piriform) is a useful, free utility which can help you with those 2 categories. As the name implies, it provides a list of all the basic specs. and hardware manufacturers of your system components so you can more easily select the correct drivers.

 

You will notice there are Windows 7 drivers for almost every category. And if you encounter a piece of hardware that doesn't seem to have a driver for Windows 7, the corresponding "Vista" driver will probably work. Notice also there is a distinction made in certain categories between Windows 7 32-bit and 64-bit drivers.
