I'd use it as-is until it expires. Liquids can cause unseen damage and even if the device is repaired it often has no repair warranty because of how you can never be sure your repair is complete. You may replace a board and later another part fails.
Hopefully you had drop and spill insurance.
Laptop: Vaio Flip 15
Some soup inside my bag spilled and my laptop was slightly affected at the right side where the power switch is (laptop was resting on this side). At first glance the laptop wasn't wet at all. I plugged in power but noticed that the charging light wouldn't turn on, implying that there was something wrong. So I opened it up, cleaned it, and the laptop works, but the screen now has an anomaly as seen on the picture.
I don't know what is the reason for this and what role could the soup have played here, but having seen people write about opening up screens and cleaning them from the inside, I would appreciate if anyone has ideas on what happened here and if you could suggest how I can fix this problem without dishing out 100 gbp on a laptop repair service.
I also uploaded a second picture for comparison to show the extent to which other things in my bag were affected. The paper was completely soaked, while the workbook was soaked along the area where the creases are. 
The third picture shows the component which I had to clean for reference. The amount of liquid I discovered was very little.
Also, since this is a convertible laptop, I DID notice some liquid between the layers which allow screen flipping.
Thank you
