How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
