Hello,
I own a T420 ThinkPad and I have recently got a CPU which has P/N on it: SR1KY. Per Google, this seems to be 4th generation of i7 (4610M). The question is if I can use it in my ThinkPad T420 to get some performance boost? Currently, the laptop has a Sandybridge CPU inside.
Thank you.

Good day! I have an R52-mobo-based T41 laptop at home and I would like to use it as a server providing multiple services like OpenVPN to connect from outside to my home, DLNA server for my TV providing storage for my films etc. and I would like to ask, whether the motherboard supports power-on over ...

T420 came home today. I finally picked the LG cells-based battery which has 120 cycles and Fedora Linux informs 5-6 hours remaining at full charge. The body is very nice, KB has no shining. I was shocked that the laptop took my Intel SSD with Fedora Linux on it (was installed on my previous T400) an...

I have done the physical review of that ThinkPad, the seller has many of them. Few of them are in mint condition, one is excellent so I have selected it - it has German keyboard layout but it's not a big issue for me and the keyboard has absolutely no shining on the keys, the laptop probably was mos...

T420's configuration is Intel i5 2520M 2.4 GHz, 8 GB DDR3 RAM, 1000 GB HDD (I will probably put there my SSD from T400), LCD 14" (1366x768), DVDRW, WiFi, battery lasts approximately 4 hours. In my current T400 I've standard LCD resolution 1280x800 so the given one is not a big issue for me since e.g...

Hi there! I got an opportunity to do the T400 --> T420 upgrade. The configuration of T420 is i5-2520M, Intel GPU, 8GB RAM, no HDD (I have an SSD), DVD-RW, LCD is 1366x768 and the battery lasts around 4 hours. I am Fedora Linux user, so I don't care a much about performance - current T400 runs GNOME ...

After playing a bit with OS/2 Warp during few previous days, I have decided to switch to Windows XP recently. Few things I don't like on OS/2 Warp: - Very slow boot - the T43 boots OS/2 very slowly, splash screen is on for few minutes until it reaches desktop - Unstable - putting a new driver caused...

I finally made the installation finished - the problem with formatting was caused by large partition (over 64GB) I used before. Now I am using 60GB partition and it formats well. After the first restart, I am getting the same error as micrex was getting (that one with COM.SYS), after hitting Enter, ...

I have been trying 4.52.14.086_W4 yesterday. The first CD disk created LVM and requested me to restart the ThinkPad. After the restart, installation program started and I went through few of the screens to the format window where I have selected 'Complete format' (sector by sector), but when the for...

Hello, I have got a T43p (with T43 ATI X300 GPU) and UXGA FlexView LCD. It is very late T43(p) with only Lenovo logos on it. Is it possible to run OS/2 on it? How fast is the OS/2 performing on this laptop? I have an experience with multiple Linux distributions on it but all seem to me a bit slow. N...

I have one of the last T43(p)s ever made (ThinkPad T-series sticker on the palmrest and Lenovo sticker under LCD) and it is still my favorite companion. I am running Debian on it and the work is still very comfortable - only trouble I have is, that it generates high pitch noise when running on AC so...

Project is completed. Final configuration is: Pentium M Dothan 1.8GHz 400MHz FSB T40-based motherboard with Radeon 7k5 GPU Long fan/heatsink is also covering the GPU 1GB DDR RAM (awaiting 2x 1GB kit from China) 80GB Fujitsu MHV2080AH (very silent & relatively fast drive) 802.11b/g Atheros WiFi card ...

For the operating system I'd recommend a stripped down Windows 7 with ati display driver version 6.14.10.6606. I've tried many light weight Linux distros on T40 and many of them do beat Windows in boot times but once the system is up and running it's surprisingly almost always been Win7 which offer...

The problem is definitely not caused by the interferences from the inverter board. Running the ThinkPad with disconnected inverter and using the table lamp, I still can see the stuttering is still there.

Inverter board is getting warm to hot (depends how long the ThinkPad is turned on). I have now put the LCD into lid assembly and using the left hole in the inverter board I tightened the inverter board to the lid. As there is contact on the board, I was assuming the connection between the inverter b...

Can be the stuttering somehow caused by exposed inverter? I am not running the LCD with cover attached, only LCD on hinges, inverter connected to cabling etc. (I did not want to assembly it without initial testing).

Cable is new from eBay, P/N 91P6805.

Apologizing for opening old topic, but I am experiencing the same issue. After upgrading to SXGA+ screen in my T40 project, screen is shaking. I took a picture of that behavior: http://1drv.ms/1UnwsuI When reseating old XGA LCD back, everything works fine. I am sure the screen has been working befor...

Where to get OS/2 Warp nowadays?

Why are the high-end Pentium Ms so expensive? Looking at feebay, ie: Pentium M 765 (top processor for T40 - T42 series with Dothan core and 400MHz bus) is 4 times more expensive than Pentium M 755 (2GHz vs 2.1GHz). The same is for Pentium M 770 vs. 780 (2.13GHz vs 2.26GHz). For my T40 project, I cur...

I am running similar configuration with my T43p, however with T43 ATI X300 board. I have noticed that the rubber pad, which is at the top of heatsink (thermal conductor from heatsink to the keyboard's sheet metal) is very helpful and I would say that it may significantly improve CPU and GPU cooling ...

I finally solved this issue. Recently, I have purchased these spare fans from feebay: http://www.ebay.com/itm/New-CPU-Cooler-Fan-T40-T41-T42-T43-T43P-FHRG-For-IBM-Lenovo-Thinkpad-/360998553160?hash=item540d30c648 and as I wrote in different topic, the cage with fan is a bit thicker than the original...

This one?

Does it mean the T40 board will drive 533Mhz Dothan afterwards at full speed?

I'm curious if T40's mobo (designed primarily for 400MHz FSB Dothans and Banias') will work with 533MHz Dothan CPU? I do remember times of my former Dell Latitude D600 which has had almost same HW as T40, that 533MHz Dothan CPU worked well there, even underperforming on 400MHz FSB. Is it going to wo...

Hey micrex, could you advise IBM mouse type (on the picture where your ThinkPad is assemblied)? I like it very much. Thanks.

Is this M10?

At least, the FRU number match.

Guys, I need to purchase other fan for my modded T43p (mobo from T43 with X300 graphics) because the current fan produces T43's-typical annoying sound when the fan shaft oscilates to the heatsink chassis, but I don't know which model to take. I know I can drill the hole to the fan cage in order to p...

I am running on Debian Jessie 8.1 (with MATE environment, former Gnome 2.x) and everything is perfect and super fast. UXGA display provides really large terminal window and enough of space to work also for graphics apps. Really like it. And you would not recognize it does not have SSD but 8years old...

The problem was probably the new Toshiba fan and its thickness causing the heatsink was not in the correct contact with CPU core. I used old heatsink with old fan, and I can feel warm airflow from the heatsink almost immediately after ThinkPad boots up. As the old fan produces some interference soun...

Yep, new Toshiba fan is blowing nicely and silently. I would say with the old fan the air which was outleting from the ThinkPad was much more warm and this new fan is blowing a bit longer time only cool air (until computer is fully booted), then it will start to warm the air slowly.
