Question about Toshiba Satellite A15-S157 Notebook
Thermal runway occurs when a semiconductor component heats up thereby allowing more current to flow through it, leading to even more heat, which quickly builts up. It seems that the best place to focus your attention is the switched mode power supply unit (the power switch tends to be right on it), since it is there that current limiters and over-voltage protection circuits will be found. Clearly, these protective measures are kicking in when a fault is detected. Check for any surface mounted transistors on this module that are getting unduly hot; sometimes even a largish electrolytic capacitor will cause such a power fault, since they tend to dry out with age and heavy usage. If you can get your hands on a similar module try swapping it in. If not, then try replacing the SMPS board components that are heating up. Experience in electronics definitely needed.
