Re: Schematics?
I'm not sure where you are, but under UK consumer law, those MSI laptops were still under at least some level of warranty, as by law an item should last a "reasonable length of time" and yours, at least, was borked by a firmware upgrade, which MSI would be directly responsible for. The broken screen, maybe less so, depends what you meant by "broken", ie user damage, or failed electronics causing lines etc in the display. Once the two year warranty is up, manufactures are still obliged to repair, replace or refund some proportion of the original cost if it fails. With laptops, it's probably 5 years or so. Repairs may be charged at labour cost and/or you pay the carriage costs to return it (Parts should be free), but in practice, your complaint is with the supplier/seller, not the manufacturer, as that's who you entered into a contract with at the point of purchase. It's pretty much the same in the EU AFAIK, but could vary wildly in other jurisdictions.
I took a coffee machine back to a retailer after just under two years, they entered my card details, found the sales record, apologised that they no longer sold that model and offered a full refund or to choose a similar model off the shelf up to 20% over the cost of the faulty one, no questions asked. Currys/PCWorld, if anyone is interested.
