You can take it apart and try and clean the keyboard, you'll most likely have to replace it (the keyboard) though.

 

Fortunately there are videos on youtube that will show you step by step how to disassemble/reassemble almost every laptop pc. No need to pay a PC tech 100's of dollars.

 

just search "your laptop model teardown"

 

Most replacement keyboards are about $30 these days, it's not a major disaster.

Just search in the bar at the top.

 

You should be able to do it. That's how I learned to do it, haven't broken a laptop yet.

fI coffee has penetrated beyond the keyboard and the computer was on at the time there is a high probability that shorts have been  created which could have damaged components beyond repair.  Using canned air to blow out the computer is going to be ineffective if this is the case.  Even if it hadn't reached this level you would need to disassemble the computer to some extent to be able to blow the water off.  The best thing to do if the computer wasn't on or wasn't damaged would be to leave it off and unplugged from the power adapter and let it dry for a couple of days.

Not sure with your model of pc, they are all different. 

 

go on youtube and search

 

your model replace keyboard

 

if you don't get any hits on that search

 

your model teardown

 

that will show you how to completely disassemble and reassemble the computer, so you'll know what's involved replacing the keyboard then.

On the following 7 steps I’ll be removing the keyboard.
By the way, it’s not necessary to go through all previous steps in order to remove the keyboard. Simply follow steps 5-11.
STEP 5.
Lift up the right side of the power button board cover with a screwdriver.

Also, for those "not in a hurry" it is worth trying removing the keyboard and either giving it a very warm shower or running it through a "rinse only" cycle in your dishwasher (no heat drying, ever) then giving it a couple of days to dry out.  Then try reinstalling it.  They will very often work again like a charm.  If not, you're not any worse off than you were and you can keep using an external keyboard until your new replacement arrives.

 

When I was a computer lab tech years ago we used to wash regular keyboards that had been the victims of spills on a regular basis and most survived and functioned without issue.  My personal experience with laptop keyboards is that they're a bit more finicky about surviving this treatment, but you've got nothing to lose by trying it if you're not in a rush to get the machine fixed and are pressed for cash.

 

Since you can pick up both mice and keyboards at virtually any thrift shop at really low cost you can at least use your laptop during the "trying to fix" period.

hi

 

my experience

as a telco tech

landlines have 2 wires

power and ground

if water crossed the 2 wires

in the manhole, on the pole, in the splice

the trouble is short circuit and x battery

of course, we are talking miles of cable from central office to customer

but

i have given electronic items a bath

unplugged, of course

lol

 

so far

inder the kep

is a plunger in the middle

under that is a circuit board

if it gets wet

isn't the board connection under the key

"blown"?

 

how can i attach a picture to these posts

 

thanks

frankie

If you want to attach pictures, when you're composing your message in the "quick reply" box at the bottom of the page just below it and to the right you'll see a button that reads, "More Reply Options" - press it.   This takes you into the full editor that has the attach button on the bottom left and you can specify whether said attached picture is to appear inline in the post or not.

 

BTW, when it comes to the current involved in powering something like a laptop keyboard "blown" is hard to achieve, though not impossible.  I've revived quite a few pieces of electronic equipment that have had unintended swimming lessons by doing nothing more than allowing them to dry very thoroughly before trying to power them back up.  These things seldom "fry" but corrosion is another issue altogether.

Normally you put the ribbon into the slot, turn the latch 90 degrees against the cable then push in 1-2 mm to lock the cable in place.
