    Hi, I recently spilled liquid on the keyboard of my Lenovo Edge 2 1580. The laptop still works fine except for one thing. Whenever I put it to sleep or shutdown, within a few seconds, the computer turns back on and returns to the login screen. It's like a ghost is pushing the power button. I dismantled the computer and cleaned any signs of corrosion with isopropanol. I concluded that it's not a battery issue because after disconnecting the battery and relying on wall power, the problem persists. I also think there's nothing wrong with the power button because otherwise the screen would constantly be turning off and on. The computer works normally until I put it to sleep/shutdown. I'm guessing that it's a ghost keyboard issue because the computer wakes spontaneously. What puzzles me is that the computer is capable of turning on once shut down. My solution as of now is to order a replacement keyboard. Thoughts?

    Hi and welcome to TSG.

    To test your idea disconnect the keyboard and see if it still turns on by itself or not.

    I replaced the keyboard and touchpad with a donor and the problem persists. I also disconnected the wifi/bluetooth module and there's no issue with that. Should I move forward with a motherboard replacement?

    Replacing the motherboard is the next logical step but it could be expensive.
