I got a Acer Aspire 7 model A715-72G-74HL and I heard from a guy at the IT store that if i have my laptop plugged in while at 100% that the power bypasses the battery and doesn't lower it's capacity and lifespan over time. And that I should charge my laptop only when it is turned off and not in use as it won't decrease it's lifetime and that I should empty out the battery sometimes and charge it while the laptop is turned off.
I haven't heard of those things before and would like to hear if it is true for me also.
Please tell me which question you can help me with so I don't mix them up.
Thanks in advance, any help is much appreciated as i had trouble finding answers for my specific questions.
