The conversion of your MacBook base system into an Axiotron Modbook voids any existing Apple warranty. Your 90-day Modcare warranty begins on the date of purchase, and any extended Axiotron dealer warranties begin immediately after this 90-day period. Axiotron makes no other warranty, either expressed or implied, with respect to this product. Only Axiotron Authorized Service Providers are authorized to service and repair your Modbook.
