I've already had this laptop for about 4 years now and it has been known to have battery and power issues since I bought it...
I had the Acer Aspire E 575G 54YE's original battery replaced since it was filled with rust.
I also had the original charger replaced since it was damaged, so today, the laptop has a third party charger and battery and it held up pretty well for almost a year until now.
I drain the battery at least once a month to give it a full cycle, but because of the pandemic, I occasionally use the laptop on battery power. I always use it plugged in.
Weeks ago, the battery gave up. The battery charging light indicator on the front on the laptop glows in both blue and orange at the same time, like saying that battery is both full and charging.
I can boot the laptop while its plugged in with the battery, but it shuts down as if the battery is depleted after 3-5 minutes.
I usually remove the battery and plug the laptop as is. The problem is, there are only certain instances where the laptop will boot without the battery. Right now the laptop won't boot without the battery.
I think I know the problem of the battery, where one cell might be dead which makes the laptop think it's full and drained at the same time since the cells are in series..?
But I want to know what's not making the laptop boot without the battery... I've been using the laptop without the battery for a year before I replaced the original battery, but it's odd that it won't boot most of the time right now...
