Laptop dies without Charger Plugged In

[ReviveMyLaptop]

Hi,

I have noticed recently that my PC would shut down at random occasions when the battery percentage was around 40% and then it started to shut down when it was 50% then 60% and so on. Now it shuts down completely when the charger is not plugged in. To operate my PC I need to keep the cable plugged into the laptop or else I will lose all my work and the laptop will turn off completely.

Is this a battery issue? if so, that is no problem I can invest in another one, but I just want confirmation that this is an issue with the battery because I don't want to end up spending money on a battery and realising later on that the issue was with another piece of hardware. I have ran all diagnostics and they cannot detect any faults with the battery.. 

All help will be appreciated - thank you.

Likely the battery but please give us the model number of the laptop. There is a battery testing app built into the HP Support Assistant and it will actually give us the results of some scientific testing which is better than a guess. The simple pass/fail is not good enough we need the advanced testing of how much storage capacity is left in the cells.

Firstly, thank you for your response and of course I am willing to provide any information I can to get this sorted, as I am a University student and I cannot afford another laptop at this point nor can I afford to lose any of my work.

Here are the details of my Laptop as requested:

HP Notebook - 15-bs107na

Piece of cake. It has an external clip-in battery so you need no teardown instructions; the data will never be at risk. This is the battery:

4-cell, 41-Whr, 2.8-Ah Li-ion battery 919701-850

The laptop is at least 4 years old so the problem is virtually 100% likely to be the battery's needing replacement due to age. Battery can be replaced for 29 pounds:

Post back for any more questions and please accept as solution if this is the info you needed.
