The ThinkPad T61 notebook computer was released in May 2007 as part of Lenovo's premier line. The business-oriented T61 includes high-end features such as a magnesium alloy rollcage, 7-row keyboard, screen latch, Lenovo UltraBay, and ThinkLight. Models included the 16:10 aspect ratio 14.1' and 15.4' widescreen, along with traditional 4:3 aspect ratio 14' screens.
Install the Middleton BIOS (additional download links below) on the ThinkPad T61 to enable the following:
  • SATA-II (3 Gbit/s) drive speeds - the stock ThinkPad T61 BIOS limits the SATA interface to 1.5 Gbit/s
  • SLIC 2.1 tables - simplify licensing of Microsoft Windows
  • Whitelist removal - allow installation of a wider variety of internal components such as wireless cards
  • Thermal sensing error fix - allow installation of Penryn-class CPUs on motherboards designed for Merom CPUs
  • CTRL-FN key swap (optional)
  • Dual-IDA (Intel Dynamic Acceleration) support - allow both cores of CPU to simultaneously run at higher speeds

Download the Middleton BIOS for the ThinkPad T61 here

  • Any standard 9.5mm 2.5-inch form factor SATA hard drive can be installed in the ThinkPad T61
  • Install a Solid State Drive (SSD) with a SATA-II or faster interface to take advantage of the significant speed increase unlocked by the Middleton BIOS

  • The Intel 965 chipset in the ThinkPad T61 supports up to 2 x 4 GB = 8 GB of non-ECC 200-pin RAM (DDR2-667 / PC2-5300 or DDR2-800 / PC2-6400)
  • Install two modules of any capacity to enable Dual Channel memory support
  • To utilize more than 3.25 GB of RAM a 64-bit operating system must be installed*

*Some 32-bit versions of Windows such as Windows Server 2003 Enterprise and Datacenter editions as well as some 32-bit Linux operating systems do support RAM over 4 GB.

*modification required to install 4:3 T61 board in 4:3 T60 or R61 models. These hybrids are commonly referred to as 'FrankenPads'
Motherboards designed to use Merom CPU can run a Penryn CPU if Middleton BIOS is installed. This modified BIOS will suppress a false thermal sensing error generated by the boards inability to read the Penryn CPU's more advanced digital temp sensor. This BIOS will NOT provide full Penryn support.
Identifying information for a T61 motherboard can be found on a label under the battery or under the RAM modules.
There is a well known issue with the nVidia discrete graphic system used on T61 series ThinkPads. It was first discovered in 2007 that these GPU chips were experiencing a greater then anticipated rate of failure. Although the rate of failure is believed to be low, perhaps less then 1%, with millions of units produced this adds up to a significant number. nVidia began addressing the problem as early as February 2008, but neither nVidia nor Lenovo ever admitted publicly that the chips were defective. The issue was handled as one of quality control with no 'official' revisions issued, and no recalls. Failure rates sharply declined after February 2008, but it wasn't until July 2008 that Lenovo removed the subject Planar Cards (motherboards) from production, replacing them with cards based on a new shipment of GPU chips.
Laptops with production date code of 08/08 (2008/August) and later are NOT affected, assuming the original motherboard is still present.
Production of the T61 series was cancelled after August 2008, but a few special order system were made in September and October 2008, and boards with the new GPU design continued to be produced until about 2010. The supply of new boards was quickly exhausted, however, and currently only refurbished boards are provided by Lenovo/IBM service. Some boards refurbished by Lenovo contain new Genuine GPU chips, while others appear to have the older original chips. To determine which chips a board contains it is necessary to examine the chip itself which bears a four digit date code represented by yy/ww (year/week). The (new) example linked above was manufactured in 2010, 21st week and the older one 2007, 25th week. Original boards from ThinkPads manufactured in August 2008 vary from 0820 to 0829. Since there were many production lines and many factories producing these chips, the actual date on the chip isn't a conclusive way to demonstrate the chip is the improved version. The date on the laptop itself is the key factor.
There have also been reports of counterfeit chips, most likely re-badged chips that were pulled from old boards, being used in boards refurbished by third parties.
Lenovo attempted to address this problem by offering free out-of-warranty repairs to anyone experiencing this problem. This free repair program ran from March 1st 2010 until March 31st 2011. Since this date there has been no further help offered by Lenovo, but the community forum has been helpful in assisting members.

The maximum CPU clock speed may be limited when the system is operated on the 65W AC adapter and no battery is installed. source
By reducing voltage the CPU will run cooler and draw less power, usually providing an extra 10 to 30 minutes of battery life.
CPU speeds can also be throttled to reduce temperatures and extend battery life.

Wireless upgrade option
From uruiamme:
With 3 antenna ports and no bluetooth, it seemed to me that the best upgrade for my Intel 4965AGN PCIe Mini Card was to find a newer Intel card that will fit in the slot with similar specs. I looked around for a card with 3 antenna ports and no bluetooth. I couldn't find one with a full length card, so I bought an adapter off eBay. I got the Intel Centrino Ultimate-N 6300 AGN card. It works fine in my T61 widescreen laptop and gets pretty good signal for me. I found out that there may have been a swapped cable on my old card, but in any case I followed the color scheme of the new card for the white/gray/black cables. My cables reached across after pulling some slack out of the area under the CPU fan. IT HAS TO HAVE a mini PCIe adapter (About $2 on eBay for two adapters with screws) My wireless speed is much improved. Note also that I am using the Middleton BIOS, which is needed to prevent the laptop from rejecting this upgrade. Hope that helps the Wiki!!
