A friend gave me an Acer Swift 3. He wanted the data out, and after that decided to just toss the thing away. It doesn't power up. Plugging it in doesn't do a thing, nothing lights up. The power ON button is part of the keyboard. PSU is working. I cracked it open and measured around 2.8V on the battery poles when plugged in, charging light doesn't go on. When I take it out, it goes from 0V to 0.15V. Well, I am quite sure that battery is gone. I've found some people complaining their Swift laptops went to sleep and never came back, and there seems to be a BIOS update to fix that. I guess that's what happened. My question is: could it be that the thing doesn't turn on because the battery is absolutely dead? I don't have a lot of experience with sleek-looking stuff, it's the old school gear that has a removable battery that I am comfortable with. Those don't usually care for the battery.
