Explanation
The symptoms - battery not charging AND the laptop failing to power on even when plugged directly into AC power - point to a failure on the system board (motherboard). The charging circuitry and the DC power input management are integrated into the motherboard. If the laptop could not power on from the AC adapter alone (bypassing the battery entirely), that rules out a simple battery failure and implicates the power regulation circuits on the board. A hard drive or memory failure would not prevent the system from powering on. A failed system fan might cause thermal shutdowns but not a total power failure. A failed wireless card has no effect on charging or power. The system board is the only component that controls both charging and AC-powered operation.
