this is the not free red hat
so your very first stop should be to the red hat support site
you ARE paying then $299/year for the required license
why not use it .
also is there a MUST USE NEED for the older 5.7 ( 5.8 is the current in the OLD 5 series )
And RHEL 6.2 is the CURRENT version
the old 5 series might not support that laptop
Did you ask your red hat sales person if it( the laptop) IS supported by 5.7 when you bought the required license ?
