Bought from one of the usual suspects online (sounds like reading something quickly). Warranties for their laptops are done direct with MSI.
Depending when you purchased the item, it is highly likely that the retailer is responsible for providing a replacement or giving you your money back under the Sale of Goods Act.
Remember, all Warranties state 'this does not affect your statutory rights' meaning that their terms cannot override your statutory rights under the Sale of Goods Act. It is also a criminal offence for a retailer to mislead you as to your statutory rights (see quote below).
Sale of Goods Acts Explained
Quote from section 4. Your responsibilities as a retailer.
"...you[the retailer] (not the manufacturer or supplier) are legally obliged to resolve the matter with the customer at any time for up to six years from the date of purchase, or in Scotland for up to five years from the discovery of the problem."
Quote from section 5. Your Customer's Rights.
"Requesting a repair or replacement
If a customer has accepted the goods and is requesting a repair or replacement because the goods are faulty, the onus on who is required to prove the problem depends on how long ago they purchased the item.
Under six months - the customer does not have to prove the item was faulty when they bought it from you. If you disagree it is up to you, the retailer, to prove the item did conform to contract (or that the fault did not exist) at the time of sale.
Over six months - you are entitled to ask the customer to prove the item was faulty when they bought it from you. If they are able to do this they are entitled to a repair or replacement."
Quote from Section 3. When can a customer claim a refund, repair or replacement – what the law says
"Complying with the law
You cannot remove a customer's legal rights, for example by displaying a notice saying 'we do not give refunds under any circumstances' or 'credit notes only in the case of faulty items'.
It is also against the law to mislead consumers about their legal rights - this could lead to a criminal prosecution under the Consumer Protection from Unfair Trading Regulations 2008."
