"Retail store or manufacturer"

The idea of a manufacturers guarantee is so that instead of calling the companies repair services who then in turn have to turn up diagnose problem and order parts. THEN fix the product and return it to the customer the manufacturer can do all of this in one swoop. many cases in many retailers is that the retailers can take upto 28 days to diagnose and repair, where the manufacturer takes only a coulpe of days. 
 
some retailers who do not have instore engineers have to have a booking in system to accept the goods back arrange with their companies engineers a time to pick it up from them and then keep it instore until it leaves the building. 
 
PCWorld for example have a clinic desk with bookings for healthchecks, repairs and services and about a weeks wait for new bookings.  
If you go into their store they would book it into their system for a weeks time (when they are free). then diagnose the fault or call their company repair service. who will then take it away a few days later. 
 
some repair services see a store pickup as less priority then a domestic (from home) pick up and instead of being at th address next day would take a couple days. 
 
then ofcourse there is the usual order parts fix and deliver back time. 
 
this just takes toooo long and inconveniences the customer fully. trust me a month without my laptop. no thanks! 
 
i call the manufacturer as they do next day swap-out. and manufacturers do not affect your legal rights with respect to Sale of Goods Act etc. 
 
so even if they swap it for a newer model you have not lost your SOGA rights. 
 
why waste petrol going to the store if they dont have engineers instore to fix laptop screens etc. or even the parts. go to the company that does
