On Bootup I receive error message about battery being diminished

[Dmagoo22]

I am receiving a message on boot up that my battery is diminished? Sometimes I need to complete a hard shutdown then for my computer to finish booting up.. I think I need to replace the battery. I have an hp pavilian but I don't see a battery, think its on the inside.

Hi @Dmagoo22 

Of course the battery is inside, but I cannot give you the model of the battery because you have not entered the complete model of the laptop.

 Some batteries are removable without opening up the laptop. The model Number of my computer is:

15-cs3153cl

Thanks in advance

only very old laptop models do not have an internal battery, this model is internal and you must open the bottom cover. The part number for the battery is as follows, use an internet search engine to find a reseller
