You won't know if Calibre 4.20 works or not unless you try it. Nothing will go wring by trying it. If it doesn't work, you just uninstall it and install 3.48.
Also, if your laptop has two video cards, you can try both of them to see if 4.20 work. Someone on the forum had a problem running some version Calibre 4 and the solution was to use the other video card for Calibre.
