Draw an outline of your medion on a sheet of paper. Use a proper screwdriver. Press all the screws through the paper at the corresponding locations (in order to relocate them).
Open the machine and carefully remove the hard disk.
If your dvd-rom device is internal, try to remove that too.
You should in fact try to remove all devices that are plugged onto the mainboard (modem, ram, BATTERY of course,....)
Wash the mainboard with electric clean solution or a proper electric cleaning aerosol. You really have to wash it, like a shower. Don`t use cloth or brushes, just shower it and let it dry by itself. Do not expose the screen to to any liquids.
Give it like 12-24 hours at 20-30 degrees celsius to dry.
Reassemble and turn your computer on.
This works.
