Info on the HD4530 click here seems to suggest it will be fine. Not sure you'll be able to run it on high settings, but it appears it'll handle medium settings. To be absolutely on the safe side, try to aim for something in the low Class 2 (see link above), e.g. a HD4570 or similar.
I ran the test for Sims 3 at the 'Can your computer run that game?' scan click here & passed (screenshot of the GPU info only click here) - it's a HD3450 (desktop though), which is slower than a HD4530. G
