1. Press and hold the power button until the computer turns off. Then, restart
the computer.
2. If step 1 does not work:
• For models with an emergency reset hole: Insert a straightened paper
clip into the emergency reset hole to cut off power supply temporarily.
Then, restart the computer with ac power connected.
• For models without an emergency reset hole: Disconnect all power
sources, press power button seven seconds. Then, reconnect to ac
power and restart the computer.
1. Carefully unplug the ac power adapter and turn off the computer
immediately. The more quickly you stop the current from passing through
the computer the more likely you will reduce damage from short circuits.
Attention: Although you might lose some data or work by turning off the
computer immediately, leaving the computer on might make your computer
unusable.

computer has keyboard drainage holes on the bottom, the liquid will be
drained out through the holes.

computer.
