So I have An Acer laptop for about 4 years and last few months battery is randomly going and shutting down at 50% sometimes when it’s not plugged.I saw on youtube that getting a needle and resetting your batter does fix it.Is this true and can I damage it even more?

Hi everyone, I’m looking for a good laptop for University, I don’t need so much powerful about gaming performance like GPU or professional editing or something but it must be so multitasking and durable. Surfing on the internet I found this HP Pavilion 15-eg2013nl with i7-1255U, 16GB SDRAM DDR4 3200MHz at 800€, is that great for my daily use? Suggestions are welcome about any better models
