My 2019 Spectre x360 13" convertible suddenly cannot turn on - either on battery (power adapter disconnected), or when is connected the power adapter. Power indicator light do not lighting at all, and no light on power button as well. Tihs happen just some hours after switched off (power adapter being connected to). When turned on, just in the begining of loading operating system, suddenly swithced off completely, and cannot turn on anymore.
Checked power adapter on other device - proved providing output power (but cannot measure exact voltage and amperes). Laptop is still under warranty.
