Think the current difference might blow the smaller one. I'll have to rummage for another one.

The rating is only the maximum output, it will only draw the needed current, so it will work fine, i use a 6amp test psu on all laptops from 3.5 upwards with no problems at all.

Its smaller rated psu on a bigger laptop where you have problems.
