Please note all that Lenovo computers are not good quality and they are all chineese product.
Lenovo computers are having outdated hardware parts and no support for games/ graphics.
There is no backward compartibility ie. P-III cd’s will not work in P-IV machine. But in general, all higher end system will support for the lower end system s/w and others.
But in Lenovo, eventhough they claim for higher end, it will not support and you can use only as a electronic typewriter. Therefore, Don’t buy any Lenovo computers and suffer more. If possible you may please inform all your friends and relative so that they can save hard earned money.
Best well wisher,
Ganesh.
