I own a Lenovo K55VD laptop and it's not switching on. The Power light comes on, including charger light and Wi-Fi light, but the screen won't start and it doesn't seem to be booting up. This will only happen if the charger is plugged in too. I tried to order a new battery and charger but that didn't help either. I did spill some water over the keyboard while ago, but that was a year before it stopped working. I was told by someone that the motherboard had died and it's unfixable.
What do you think has stopped working and if it is the motherboard, can it be repaired?
