Acer nitr 5 an 515-57. I opened the back cover to add ssd nvme, the store said the warranty disappears when you open the cover. Do i still have the warranty?
P.s. I need an official answer from Acer.

It varies from region to region. Laptop warranties aren't voided by upgrading or opening the back panel. In some countries, there is a sticker on the back of the laptop that blocks access to the screws. Removing that sticker and opening the laptop will void the warranty. If the sticker isn't present, you don't need to worry.

Here is what it looks like-

The official answer will probably be what the Acer Policy states: Yes, breaking the seal on the back cover screw(s) will void the warranty. In practice it depends on the country where you live how that policy is enforced, In the Philippines it won't matter if you opened the back cover as long as you don't open anything else like disassembling the motherboard/chips and caused no damage to any components, don't clean the fans with liquids don't lubricate hinges and/or fan bearings or use a vacuum cleaner and always disconnect the power adapter and battery (common sense) use the proper screwdriver type and size, screws are locked with a compound that take force to unscrew and you may strip the screw(s) and that could be a reason to void the warranty,
