Argos would be liable under consumer law as they are the retailer....
If you purchase from a business then you have rights under the Consumer Rights Act 2015, which states that the item has to be:
· of satisfactory quality in that it must not be faulty or damaged when received
· as described in that the laptop must match any description given at the time of purchase
· fit for purpose in that it should be fit for the purpose intended
If the laptop does not meet the above then you will be able to enforce your rights and sue for your money if Argos refuses to give you the money back. The claim would not be against the manufacturer as they will only be responsible under their warranty which came with the laptop.
The rights against the seller are:
1. Reject the laptop and request a refund which must be done within 30 days of purchase or delivery. The faults are presumed to be there from the outset unless the retailer can prove otherwise.
2. Repair or replacement and this can be done within the first 30 days or after, if that deadline has passed and a rejection is no longer possible.
You need to contact Argos and advise them of which option you want to go through with. If they refuse then I would advise that you report them to Trading Standards (tel: 0808(###) ###-#### and commence legal proceedings via the money claim online site (www.moneyclaim.gov.uk) for your money back.
Before you do this however you should send them a 14 day letter before action to warn them of your intentions, to allow them to avoid litigation and resolve this dispute.
I attach a template letter for you to use which will hopefully resolve the dispute. If you have had the item for 6 months or more, the burden of proof shifts to you as the consumer to prove the item was faulty from the outset - so you will need a report from someone independent to support your case before you issue court proceedings. If you do not do this, the claim is likely to fail.
