Thinkpads Forum

Am I correct to say that I have an
Intel Centrino Pro 900 series chipset
utilizing a T7300 (Intel Core 2 Duo) CPU
which is part of the Merom family
in the Santa Rosa platform?

I am not able to determine production date. Is it (e.g. 08/01) printed on a sticker?

ThinkPad T61 (8895-W14)
Based on 8895-CTO: T7300(2GHz), 2GB RAM, 100GB 7200rpm HD, 14.1in 1024x768 LCD, Intel X3100, CDRW/DVDRW, Intel 802.11agn(n-disabled), Bluetooth, Modem, 1Gb Ethernet, UltraNav, Secure chip, 6c Li-Ion, WinXP Pro

At first, I was disappointed to see that there is a Intel Centrino Pro sticker on the palm rest. I was expecting to see Intel Core 2 Duo.

http://en.wikipedia.org/wiki/Centrino says that the 900 series Intel Chipset can be Napa (which includes Intel Core Duo and Intel Core 2 Duo CPU's) or Santa Rosa (which includes Intel Core 2 Duo CPU).

http://www.thinkwiki.org/wiki/Intel_Core_2_Duo_(Merom) says that CPU's named T7100, T7300, T7500, T7700, and T7800 are part of the Merom family of CPU's. Also, they are 800MHz FSB's which make them part of the Santa Rosa platform.

http://www.thinkwiki.org/wiki/Intel_Core_2_Duo_(Penryn) says that CPU's named T8100, T8300, T9300, and T9500 (from custom built T61p) are part of the Penryn family. Also, they are 800MHz FSB's which make them part of the Santa Rosa platform 1066MHz FSB's would be part of the 4 series Intel chipset and the Montevina platform.

You are correct in all your assumptions.
Napa is in T60/R60.
Santa Rosa is in T61/R61
The date in format YY/MM is after the S/N (L3-12345) on the label on the bottom of the laptop.

Nothing is printed after "Type 8895 - W14" and "S/N L3-X9999" on the bar code label on the bottom of my laptop.

Does this make my T61 one of the first ones produced?

You can check the status of your machine's warranty at support.lenovo.com/en_US/product-service/warranty-status/default.page, and based on that date calculate the time of it's expiration backwards by the amount of time for which the machine was under warranty. This way you can get a rough estimation about it's actual production date.

I already tried this for you based on the serial number you stated, but there is either no warranty information available for your machine (happens once in a while), or the given serial number was, for obvious reasons, simply obfuscated by yourself in a very sane approach to prevent providing private information on a public forum.

Thanks, I'll try that later.

You are correct.

In the subsequent parts listing, the mainboard is usually specified, often two times, by the term "PLANAR", with the second number from the left usually being the respective FRU. You may want to try that with your own Thinkpad's type and serial number in order to see how it works.

Intel GM965
42W7648 Merom
42W7872 Penryn

Therefore, I have 42W7648 which is a motherboard designed for Merom CPU's.

I am not as fortunate as the gentleman in the other post, whose T61 has a Merom CPU mounted on a Penryn motherboard.
