I just came back from travel after 2 weeks and didn't bring my laptop. I know for sure when I left, my triton 500 has 100% of battery charge left. When I turn on the laptop just now, it shows 62% of battery left. Is this a normal behaviour?  When I left it was not left in hibernate or sleep mode. It was turned off completely. My model is PT515-51 (RTX 2060).

    One thing we must understand is that the battery of a laptop does not store charge forever. The battery will drain even if the laptop is shut down. But this drainage will be so minimal that we don’t feel it unless we keep the laptop shut down for a long period of time.

    It is normal for a battery to drain even when it is not in use and a batteries ability to hold a charge decreases over time.

    Please double check that the system is shutting down and not actually going into sleep mode instead.

    Do you push the physical Power Button, click the Start Menu Power Off or simply close the lid?   

    Please Click or tap Power on the Start menu and click on shutdown or Try to use windows + x ( on keyboard ) and click on shutdown or signout to shutdown the computer.

    So a nearly 10% drop in battery whilst the laptop is switched off is not excessive!.  I understand that you came back from travel after 2 weeks.

    "The maximum charge capacity of every battery decreases over time and with use. The rate at which this capacity decreases can vary depending on product configuration, product model, operating system, type of software used, power management settings, and other factors.

    If you have 'fast startup' enabled, this can cause battery drain even when laptop is switched off.

    If 'fast startup' is disabled, then check if you have any device connected to USB port which supports charging. USB charging works, even when the system is powered off. Irrespective of connected device draws power or not, this can cause battery drain.

    mnemonics also want to add to what was already said that if you leave devices connected to the usb ports (depending on the port itself) some ports will be always on even after shutdown to recharge mobile devices with the device off and this will of course drain the battery and its not good for it either the usp ports power on can usually be disabled in the bios or acer software they come enabled by default
