JB replaced my Toshiba ultrabook 2 yrs & 1 wk after purchase.
I had asked to speak with a manager who came right away and, unusually for most businesses, knew her consumer law from JB's staff training. She revealed that JB volunteered an extra year warrantee over Toshiba's (substandard) 1 yr warrantee, and believed me that the fault developed within 2 yrs and that I had needed 2 wks to first get a tech to test it & then time to get in from the country. However their repairer, Leader, took ages to determine it was unrepairable.
Excellent value when you consider you get an extra year's warrantee for free.

Approximate cost: $1100
