product Name: Hp laptop 15-da0014ne

Product Number: [personal info removed]

Error Message: when I was using my laptop suddenly it turns off. Then I tried to turn it on, but it didn't respond only a Black screen was shown. When I turn on the power button the power led turn on & stay 10-15 seconds then goes turn off. then I tried some changes by opening my laptop, I can find some errors.

(1)when I removed my laptop battery & connect it with AC & turned it on but it doesn't work.--------(2 RAM + Battery = Black Screen )
(2)Then I remove my 1 RAM (it contains two 8GB Ram)And Again power on with AC my laptop turn on & work perfectly. ---------(1RAM + No Battery = Work perfectly )
(3) when I put my laptop battery it goes in previous conditions Black Screen---------( 1RAM + Battery= Black Screen )
(4) I changed the Ram slot & RAM but it doesn't work. It works only with 1 RAM & No Battery.--------(1RAM + 1 RAM + No Battery = Black Screen )
Note:

( i.) My both RAM & RAM slot full ok. ( laptop open when it has 1 RAM it doesn't matter which RAM or Which Slot)

(ii.) the laptop battery is overcharged. when diagnosed it shows error messages like, (Primary Battery Calibrate) & I couldn't discharge anymore because the laptop can not open on Battery support.

Thanks in advance
