1. Extended warranty details and availability can vary from region to region, so tell us where you are located and where you purchased the notebook if you would like to get opinions from others in your region.
2. You may want to request something in writing about the extended warranty you plan to purchase so you can study it carefully.
a. If it matters, confirm who will fix your notebook under the extended warranty you plan to purchase since it's possible there is extended warranty sold and taken care of by someone other than ASUS (third party).
3. If interested, check with your local ASUS support about the availability and details of any 'ASUS extended warranty' at this contact page (and ask for something in writing while you're at it?):
