At around 120C or so lead solder can become weaker, and this temperature is forbidden in devices that experience vibration or other perturbations. Unleaded solders can handle higher temperatures. All consumer products today are RoHS 6 and so do not have lead.
It would not surprise me if a heavily written ss device in an unventilated environment, such a laptop on a bed with a blanket covering it, or left operating in a bag, could get close to such a temperature on the PCBA. It would also dissipate heat to the USB connector of the laptop, possibly weakening it as well.
