In order, Toshiba, ASUS, Acer.
Dell? Just as bad as HP.
In my humble opinion of course

Oh yes, forgot ASUS. I have been liking the look of Toshiba for price and quality. Dell was just a thought ... they're pretty expensive.
After 30 years in the PC end of the IT industry my current Notebook recommendations would be Toshiba, if you can afford them as they are pretty pricy at the top end, MSI which is what I use, Lenovo which used to be IBM, Asus and then the others. I don't really rate any of the rest - HP, Compaq, Sony, Acer and Dell etc.
Manufacturers Warranty on Notebooks is generally 12 Months (Batteries usually 6 Months) unless you purchase an extended warranty. Based on 30 years experience in selling, repairing and supporting computers I believe that it is unreasonable to expect any retailer to repair or replace a computer for "free" for 5 years or provide replacements and refunds unless the consumer is prepared to see a significant price increase as retailers just do not have the margin to do this.
Because the manufacturers warranty on the computer and it's components with the possible exception of Hard Drives is in most cases significantly less than 5 years the reseller has no recourse to the manufacturers who are located offshore and not governed by NZ consumer law. Therefore you are asking the retailler to carry the cost, this is plainly unfair and uneconomic for the retailer. Have you ever tried to get a refund or compensation from Microsoft?
Potentially a retailer could be asked by a consumer to refund the full purchase price of a 5 year old computer and simply buy another current model with the refund and could end up replacing their computer for free evey 4 - 5 years. Is that a rip-off or not?
In my experience not many Consumer computers last 5 years besides the technology is usually way out of date or obselete well within 5 years but I guess that does not figure in this argument and we wonder why we are left with only the likes of Harvey Norman and Noel Leeming selling computers to consumers. Note: Computer/technology obselecence is currently rated at around 9 months.
Some food for thought.
Kind Regards
