Hmm... Well, it could be left over sugar/syrup residue inside your system.

If things get worse, and you find no other solution, then before discarding the laptop you can try a final solution...

Note: the final solution is an extremely RISKY attempt at a fix...

so ya... anyways, essentially this insane tip is for you to actually try completely removing the battery and giving the entire laptop a good rinse-down under cold water, to flush away all of the sugar/syrup residuals!

That actually saved one of my gaming keyboards (in which I had spilled Coca Cola on it).

And yes... I know, I know this last-resort suggestion sounds really crazy... and insane...

but essentially many of today's electronics can take a soaking, and will function just fine afterwards, provided:

1) There is no power flowing through the circuits when it gets wet.

2) You allow the device to COMPLETELY dry before turning it back on.

The reason for that is because if the device gets wet while powered up, then the water short circuits the electric current flow, and allows the electricity to jump to places it should not.

But if the device has no power running through it, then then no short circuiting can take place.

In your case, you might have caused a permanent damaging short circuit...

Or you might only have a mild ongoing short circuit (in which electricity is jumping using a sugar crystal bridge from the residual syrup... sugar's not the best conductor, but it will still allow some electrons to flow across it).

As well it could be sugar in your fan motors...

So you can first try removing the fan first (if possible) and rinse that, let it dry COMPLETELY and then reinstall the fan...

(Or just try buying a new fan if their cheap for your model. Fans are usually pretty cheap.)

But yes... to see for yourself how this water-rinse technique actually works...

Find yourself a sacrificial cheap electronic device (like a spare cheap keyboard, or spare remote control for an old TV device you're not using anymore, or a cheap calculator, etc...).

Make sure there is no power flowing through the device (remove batteries).

Next, drop the device into a sink of water, or hold it under a flowing tap.

After that, shake out the water really well (maybe in the bathtub) and then set the device aside and let it dry out.

I recommend at least 1 week drying time.

Finally power up the device, and it should work fine!

So as a last resort... if you find the machine is no longer workable... this might work... or it might not (and it might be the last nail in the coffin of your device!).
