Some keys don't work

df1995

I have an Acer C720. It got wet. I 7turned it upside down and dried it out but some keys still do not work: t, h, 7, 8.

 

Any suggestions? TIA.

Some keyboards behave this way when pieces of food or water get to some parts of the keyboard

 

I'll suggest you replace it with new one or 

Get a small painting brush and try to remove any dirt you find

 

Sometimes the rubber (sometimes a sprint) position too may have been shifted or locked

You can do it by removing the keys with caution, so that you break anything.

 

If you try troubleshooting above and still fail, pls consult a technician
