HP Prime G2 die when i turn it off while charging

[landim]

Hello Guys. I don't know should if reactivate this topic, but, my problem is similar. I have a NW280AA HP prime model. A Long time ago, I didn't have the charger original, and I used the turbo chager from my smartphone to charge the calculator. So, I did forget this on the plug, and when I remove the calculator of the charge, the temp was very high and didn't power on. I disassembled the calculator, and looked for the U302 and U306, this chips were burned. Someone can help me? I need the code of this chips for purchase and replace them. My english is just a little, sorry for wrongs.
