My laptop (HP 15 Notebook PC) won't boot unless it is plugged in even though the battery apparently has charge. (It won't charge past 73% also?) If I unplug the power supply it will die instantly. This started happening yesterday after I installed the latest windows 10 update and I just wanted to see if It is software thing before I go and buy a new battery, any help appreciated thanks.
This means the battery needs to be replaced. You can get another one from Ebay, just type in your make and model# computer with the word Battery,It won't charge past 73%
There is actually a bug with the HP and other laptop battery packs that are not reporting the charge info correctly. The bug came out shortly after 8.1 when they were finishing up the polish on 10 came out as an RTM. You will find tons of posts from HP users about this, along with Youtube videos. It is because of ACPI and the battery driver got messed up when Microsoft uses their default drivers.
Check HP's Support forums on this if HP put up a link for the new ACPI and Power/Battery control drivers for your laptop. When you post the model, you need to post the whole model series that is on the sticker on the bottom, not just the first two. That is because when HP sells to say Best Buy, Costco, Walmart, different countries. The first two digits or alpha will be the same, but the important part is what is after that, along with the model type if they have it under one, because like model series numbers, there are also model designs that can use the same model series numbers.
