Unknown bateery draining when shut down
Hello, was wondering if anyone can help me out here. I have Zorin OS 18.1 Core installed on my laptop, the model is the HP Pavillion 15-cw1511sa. I have recently been experiencing issues where i can charge my laptop to full or any percentage while switch on or powered off, but when i come back to teh laptop at a later date even if its 12 or so hours later, from 100 percent its managed to drain to around 80. This was while shut downa nd powered off. I am not sure if this is a new issue for me or if anyone esle is experiencing similar. Any help as to how i can fix this would be greatly appreciated as i have really enjoyed my experience with Zorin so far! And i dont want this to become an on going problem for me (It could be to do with the fact its 5 years old but the life on it is still pretty good and way to good for it to be draining this fast while off, however it doesnt make this theory impossible). Many thanks!
