Liquid Damage Samsung Laptop

[ddahlstrom]

A customer brought in a new Samsung Notebook 9 NP900X5N that was purchased a few months ago. 2 nights ago, they accidentally knocked a glass of liquor and juice onto the keyboard. Laptop works fine and all keys/ports and functions are responsive, however some of the keys in the center of keyboard are now very sticky and can hardly be used. Any advice on how I should go about trying to clean something like this where the keyboard is not easily removable?

Pull off the key caps and remove the hinges and clean them all out. Also clean the keyboard frame with a damp tooth brush and suck out the moisture with a vacuum cleaner.

When cleaning out frame, should I use rubbing alcohol or regular water? I tried what you said on a couple keys to test and used 91% alcohol, but the keys are still slightly sticky after a couple of days.

I'd first of all get a higher alcohol concentration Isopropanol. I'm using 99.9% which means I know its all going to be gone when it dries up. The 91% you're using leaves 9% of 'something else' which may or may not end up staying in the area you want to clean up.
Stubbornly sticky keys tend to simply require more tedious cleaning. You can dump the hinges in a container with alcohol and move it about for a while, then clean them again with a brush and/or q-tips. If that doesn't work, or if you only have a couple of semi-sticky keys remaining, you could consider taking the hinges apart carefully. They're two-part plastic bits, but be careful as they're frail little buggers.

Just water, alcohol does not dissolve sugars well, simple science! This is also why you should not just use alcohol to clean a water/sticky damaged motherboard use WATER.
