How did you clean the screen? If you use too much liquid it could get into the interior and short out parts.

Only by small amount of water

Try removing the battery and disconnect the ac adapter. Hold the power button for 30 seconds and then plug in the ac adapter and see if it boots. If the computer worked before cleaning but not after cleaning it, then something may have happened during cleaning. If this power reset does not work then the next thing to do would be to take the covers off and look for damage. Check for the disassembly guide for your computer on the Repair Guides section of this site.

If you have a volt meter, use it to test the output of your ac adapter. The voltage output should be listed on the adapter. Take care not to short the contacts in the connector. If the voltage is good then the problem is in the laptop's system board.
