T61/X61 SATA II 1.5 Gb/s cap - willing to pay for a solution

7Zip can open RAR files and best of all it's free to download and use.

If for some reason you're still struggling I've uploaded the contents in a zip file so you shouldn't have issues opening it under the latest Windows OS. Just copy the contents over to your formatted USB stick and follow the previous instructions to flash.

 

On a seperate note. Has anyone upgraded the ram to beyond the stated 4gb. Has it had much improvement. I've been looking at prices of he necessary ram but don't see any cheap options (local shop said it was more expensive as it was server ram, which confused me!).

 

If you mean DDR2 SODIMM modules then yes they're expensive compared to the newer DDR3/DDR4 modules you see today. Your best bet are second hand modules from places such as eBay, look for branded ones such as Crucial and Kingston as they should still have lifetime warranty on them. They're not server RAM by the way, I think the poor guy was just as confused!

Your X61 Tablet will work with 8GB RAM, my own T61 runs on 8GB DDR2 RAM just fine. Scale of improvement is rather subjective as it depends on your usage, I tend to open quite a number of browser tabs simultaneously so having the extra breathing space helps for me compared to 4GB RAM.

 

Hey PatchySan. 7zip worked a treat. Thanks for that recommendation. Got the bios patch to work via your method above. Thanks. And thanks for the ram info. Your very helpful.

 

Hi! I've tried today to flash the Middleton's BIOS on my Lenovo R61e (7650 type). I've downloaded it, and burned img file in ImgBurn. Then I rebooted to BIOS and selected CD as a Primary Boot Device. I've rebooted and then it started automatically without any pressing. It said: "Starting flashing". It showed "Done" and rebooted. Then it turned on one more time and was flashing one more time. How many times should it be flashing? I've interrupted the process after the third reboot (when it showed Lenovo logo) by pressing F1, so nothing bad happened.
I've rebooted to Windows, but it still shows Serial Ata 150. My HDD is Samsung HM500JI so it supports Sata II.

In BIOS I have version 7PETC3WW, which I think is not the Middletone's but Lenovo's original one.

I've been flashing the version without ctrl+fn swap.
What should I do? It looks like the BIOS didn't flash, even though it was showing "Done" and rebooting.

 

Hi Folks,

I have a T61 6470CTO with BIOS version 7LETC7WW (2.27) 04/08/2010 running XP Pro SP3.

I would like to know if the Middleton BIOS 2.29-1.08 will work for this model - 6470CTO. I didn't quite understand if the listed 77xx product codes only applied to the R61 models or to the T61 as well.

To flash the BIOS I only need to follow the instructions in the READ_ME!!!.txt and run WINUPTP.exe correct? Since I'm on Windows XP I shouldn't need to burn the ISO to a CD ... I plan to install get an SSD, install Win 7 or 10 and upgrade the memory to 8G later on.

Your input is appreciated. I don't want to brick my T61 with an incompatible BIOS. I am technical but have little experiencing flashing BIOS-es. Thank you.

 

No, the different modded BIOS editions only applies to R61 series, the T61 series uses the same edition of modded BIOS, no matter if you have Intel or Nvidia graphics; 14.1" normal screen, 14.1" widescreen or 15.4" widescreen. Just go ahead

I did that once in my 15.4" T61 a few months ago, didn't brick it and it's now running Win 10 happily.

Note that you'll need a 32-bit OS to update the BIOS (which you have).

 

So I'm attempting to update the BIOS on my X300. I followed similar steps to what PatchySan did (the HP USB utility wasn't working for me, so I used Rufus instead, with FAT32 and "Create a bootable disk using FreeDOS" option checked). I used WinRAR to open the ISO file, extracted the contents, and copied them over to the USB drive. After entering "FLASH2 /u" in the prompt, I get the "invalid opcode" errors. Any advice?
