You should only use the power adapter that your laptop manufacturer recommends.
It seems fine though, since it's supplying the same voltage. The higher current (4.5A vs 3.5A) means it may charge your battery a little faster.. but I still recommend that you get one from the manufacturer (if you think your laptop is worth spending extra on buying it).
