Sanjay has a great suggestion here. If you are able to get it to work in a different laptop, we will want to know the specifcations of the laptops you tried, so we can try to narrow down the root of the issue.
Another thing to try is contacting the laptop manufacturer if there is a BIOS upgrade. It may be an issue with the PCMCIA card carrier that the manufacturer fixed at a later date in the BIOS. If you still have trouble, I recommend working directly with our Applications Engineers over the phone. You can start a service request at http://www.ni.com/support.
