I have had my laptop for 4 years and I was able to play games on it fine while charging. Recently, when I play games (specifically League of Legends), my laptop stopped charging and I would get random lag/fps spikes. The original charger outputs 19 V and 4.74 amp so I bought a universal laptop charger with the same output to determine if it was the adapter itself. The new adapter I bought experienced the same problem. I also tried to take out the battery out leaving only the adapter in but the computer would randomly turn off if I started to play games. Any clue what might be the problem? I have 2 batteries as well and they both experience this.
