Be more careful with your laptop from now on if you want it to work properly. Another very good precautionary measure I would advise to buy a cover for the keyboard, which will protect it and the laptop from getting inside, dust, sand, water and other things. It will be much cheaper than buying a new laptop because of the accidentally spilled mug of tea. You can choose one here https://www.amazon.co.uk/dp/B09PLK95W3 . I hope it is helpful and helpful to you. Good luck!
