My brother has got a very old Lenovo T42 laptop, and he asked me to install Windows 7 on it but I'm not sure it can run it. So my question is: Can a laptop so old run Windows 7?


  • 15.1" screen size
  • 1 GB RAM
  • 100 GB HDD
  • 1.7 GHz single core
  • HD 9600 64 MB

And can I just use RAM from my Asus N53J? Normal 204-pin?

What's with "Windows 7 or 8". Seems to me you are asking if it can run Windows 7 only. Did you mean XP or 7, Vista or 7? – Josiah Dec 13 '12 at 13:43
Max out the RAM at least, and if you want a nice boost replace the HDD with an SSD and watch it fly! – Karan Dec 13 '12 at 21:24

Try it and see. From the specs given it ought to run Windows7 without any problems, although it's towards the low end of the requirements, so it might be a bit slow when running lots of programs.

Interestingly you might prefer to try running Windows8 on it; Windows was substantively rewritten in order to work better on low-end devices like tablets for Windows8, so you might find (counter-intutively) that upgrading past Windows7 might be better for your old machine than going just to Win7.

If you've just got a new laptop you should be formatting and reinstalling the whole OS anyway, and if there's some good reason why Windows won't be able to run on that machine, the OS installer will tell you and abort.

+1 I agree with the Windows 8 part – JustinD Dec 13 '12 at 13:45
Yes that is true. I found that Windows 8 ran wonderfully on my pathetic netbook. 1 GB of RAM, Intel Atom Core, all that jazz. It actually ran better than XP. Quite amazing really. – Josiah Dec 13 '12 at 13:48

I believe that it may be able to run Windows 7, but you're looking at the bare minimum there. If you were to install it, make sure to purchase the 32-Bit version of the OS and disable any type of extra graphics like Aero and switch it to Windows Classic theme.

You can also download the Windows 7 Upgrade Advisor to see if it is compatible.

+1 For the upgrade advisor. You should look at that. – Josiah Dec 13 '12 at 13:43

I would try this if the system meets everything this has then yes his computer can run windows 7. Windows 7 Upgrade Advisor

Your specs say you can install W7 on your laptop... Try 32-bit version and get Upadtes. You will probably have to install some drivers manually, but I think it will work.
