Can I install 64-bit OS on my Dell Inspiron 1545 laptop?

Question

My Dell Inspiron 1545 laptop features the Intel Pentium Dual Core T4200 processor. When I bought it, it came preinstalled with Windows Vista Home Basic, 32-bit. I'm considering upgrading it to Windows 7 Home Premium, but I don't know whether I should order the 64-bit or 32-bit version. The information I found on the web has been confusing.

Does anyone know if my laptop supports 64-bit OS?

Solution 1

Go to support.dell.com and enter your laptop service tag. Look at the shipped configuration, locate the row for the CPU. Is it a 5000 series? If so, it is a 64 bit.

Or, a less scientific method would be to look at the drivers list and see if there are any 64 bit drivers.

(My Dell laptop has a 64 bit CPU but only preinstalled Vista Home 32 bit :-( )

You can try using a program like CPU-Z to see your processor information

You'll want to look for either EM64T or AMD64 in the "Instructions" field:
