Brand is largely irrelevant.
True, to some extent.
Warranty regulations wary in different countries but in any case all global brands stand behind their products for a given time. Things may be different with house brands, though. For the price you may get a bit more powerful components which make them a tempting purchase. So far so good, but what if something goes wrong before due time? Recently a customer asked my opinion for repairing such a laptop, the keyboard was partially failing after mere months. So he took it to the store to be repaired under warranty. The laptop came back without having been fixed with the explanation was that it's a moisture damage. The customer said that nothing has been spilled on the laptop. Of course it's possible that a family member has done that but decided not to confess. Anyhow, house brand laptops include parts that may be very hard to find as spares so it's also tempting for the repair personnel to tell that the damage is caused by the customer and thus not under warranty. Word against word, and especially when talking about moisture related issues on a circuit board there's no way the customer can prove that such doesn't exist. Heck, laptops are designed to be carried around and if the outdoors temperature is different to that indoors some condensation
will happen and that can leave marks inside the laptop.
Related to the above, back in the day I read about an Iphone been refused to be repaired under warranty because of moisture damage. Said damage was caused by the owner having had the phone in their inside breast pocket so that the moisture evaporating from their skin could not escape. The operating temperature range for Iphones is 32º to 95ºF (0-35C) so outdoor usage in the winter is not recommended, nor should they be used in the hot summer weather. And how about the arm bands or sleeve pockets used by joggers, skiers and other outdoor active people? Does that mean that mobile devices such as laptops and cell phones are intended for temperature controlled indoors only?
