You should try contact Lenovo Malaysia instead of Lenovo US, because you are going to send warranty here not there. I just happened asked one of the Lenovo authorized reseller staff from brightstar, he said you can claim the international warranty for US version notebook but you must have the original receipt of the shop you bought from US, so this receipt should be with the dealer that brought the notebook from US, but it might be tricky to get that receipt as they usually buy bulk.

I also ask the seller that selling the US version, he said u can send the notebook to him for warranty, which really concern me.

I just share what I have been told. If u have the extra money just buy the local set, it reduce the risk. somemore u get 2 years warranty.
