Why is my laptop not working with the AC adapter I bought online for it?

Episode 947 (2:24:55)

Michael from Upland, CA

Michael has a laptop adapter that burned out. He bought a new one online and now there's something wrong with his laptop. Leo says it could be powering on but the LCD screen isn't lighting up. Michael also found out that the voltage doesn't match his original one. Leo says matching voltage is vital to run the laptop, and if it's underpowered, it just won't work. When working with a laptop, it's best to stick with the original laptop manufacturer version, and not a cheap, Chinese knock off.
