HP Prime G2 die when i turn it off while charging

[dophuc]

Hello everyone,

I have a problem with my HP Prime G2 (2AP18AA). I just received it a few days ago, brand new so this is the first charge. When the device is off, I plug in the charger, the screen lights up and the icon says charging. I saw the screen light so I decided to turn it off (while still plugged in the charger), as soon as I pressed [Shift] + [On] keys to turn off the device, the screen suddenly flashed and there was a small noise with a slight smell burned and the calculator turned off. I immediately unplugged the charging cord, removed the battery and the cover. After removing the lid to look at it, I noticed that one component was burned and had a strong burning smell. I don't understand why it happens because I usually turn off my Ti84 plus CE while charging and nothing happens. Previously I also had HP Prime, version NW280AA, it also died while charging for no reason.
I don't understand how HP Prime can be damaged so easily, it's clearly a hardware or design fault.
According to the information I find out, the burnt component maybe is the A476 tatalum capacitor. Please help, Is my case covered by warranty? if not, where can I find this part to replace the burnt part of my HP Prime G2, will it work again?
Thank you everyone!
