My laptop leaking a fluid. Strange!!

[Eishmay]

My HP probook 450 is leaking a clear fluid.  Happened 2 times with me. But overall working properly, but fluid leakage isn't a good thing. Both times I rremoved it's batteries and put its face down in sunshine. What to do? Change its battery?

Hi, I have a Probook 640 G4, and as I opened it yesterday, found a liquid of some sort in bottom right corner of keyboard, in other words, just below the fingerprint sensor, and then obviously since it was closed, also in the top right corner of the screen! Now today, I tried to blow it with a blower, as it has made light marks now, on both the places. So I used a blower on a slower setting and just blew as long as I could, however it did not change any of the mark's appearances. But when I switch my screen on, there is blueish marks displayed on where this liquid is from. 

And I will be honest, I was so chuffed with this new superfast laptop, and have had laptops for years, and many different one's, yet, this has NEVER EVER happened to me. I need some answer/assistance, as I would never have spilled any liquid on it, and since I take Special care of all my stuff, I am so heart sore about this, and don't know what I should do? This laptop is still under HP GUARANTEE, although it came from overseas, I am in SA though. I don't know whether this is a HP Fault, or is it covered? I really need assistance urgently. Before it get's worse or beyond repair. Which will honestly break me! HP PLEASE HELP!!
