Have you ever had a laptop which works with battery connected but it doesn’t with its adaptor? Well we have a Lenovo laptop on the video below which works perfectly with its battery but as soon as we plug in the adaptor (with no battery), it turns ON for a second but turns OFF right after. We tested it with another adaptor and even with a power supply and made sure the problem doesn’t have anything to do with the adaptor. In similar cases, it’s usually the problematic charging circuit or its components. But even that wasn’t the case on this laptop.
So if you’re curious to know what the problem was and how to fix it, we recommend watching the video 💚😊
This video is dubbed into English!
