: Many 4540s models include an AMD Radeon HD 7650M GPU. The boardview is vital here to locate the dedicated video memory chips and the GPU's specific power rails.

: The laptop contains a whitelist for Wi-Fi cards, meaning you cannot easily upgrade to modern Wi-Fi 6 cards without specific workarounds or compatible parts. Disassembly Complexity
