Lenovo laptop battery issue

Report
-
Hello,

I accidentally spilled a glass of water on my laptop. I disconnect the battery and let it dry for a few days. Now when I connect the battery, the orange light flashes and when i press power button nothing happens but if i hold it for 3-4 seconds it will turn on and everything works fine except does not showing battery and says plugged in.

If i disconnect the battery and plug ac charger nothing happens.

Battery connected and plugged ac charger same results as not plugged in
