HP Laptop 15-da0xxx
Microsoft Windows 10 (64-bit)

Hello. I have a problem with my battery status. It stopped working some time ago (my lapton only works when it's plugged in. otherwise the battery runs out of power in a few minutes). I have run the HP Support Assistant and the result it gave me was "the battery is weak because of its own wear". I also have some information such as the manufacturer, serie number, capacity, etc. So, my question is, how do I know which battery to but? And where do I find it? I have been searching online but I don't know if it has to be the exact same battery as I alredy have or if is it enough with having the same manufacturer, serie number, capacity and CT number. Also, I'm from Spain so there isn't physical stores where I can go ask.


Thank you,




Buenas. Tengo un problema con la batería. Dejó de funcionar por sí sola hace tiempo (es decir, si no tengo el portátil enchufado cuando lo uso, la batería se agota en unos 10 minutos). Entiendo que el problema es de la batería: he ejecutado HP Support Assistant y el resultado del diagnóstico de la batería ha sido que "es débil debido al desgaste normal de ésta". Me ha proporcionado también los datos sobre la batería que tengo (fabricante, nº de serie, capacidad de carga, etc). Mi duda es, ¿cómo sé qué batería comprar y de dónde? He estado mirando páginas para comprar una pero no sé si tiene que ser exactamente la misma que tenía o si simplemente es suficiente con que coincidan fabricante, nº de serie, capacidad de carga y nº CT. Además, tiene que llegar a España, así que tampoco hay tiendas físicas a las que pueda ir a informarme.

I understand that you have an HP Laptop 15-Da0xxx and the battery issue 


Did any software changes or updates happen on your laptop after which the battery stopped charging at 70%?


While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

NOTE: You may skip any steps that have been performed by you already.

  • Power off the laptop.
  • Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
  • Disconnected AC adapter from the laptop.
  • Press and hold the power button for 15 seconds.
  • Reconnect the battery and plug the AC adapter.
  • Power ON the laptop.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

  • Open the device manager. 
  • Expand "Batteries". Right click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
  • Close the device manager.Restart the laptop.
  • The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to battery draining out. 


Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".


I sincerely hope this fixes the issue. Keep me posted. 



Hope this helps! Keep me posted.
