I have an Acer Inspire E14.  I spilled a bit of unsweetened coffee on it. I turned it upside down nd wiped it off. But then realised a couple of the keys ween't working.

 

I let it dry till the next day, but it's still not working

 

I pulled the offending keys off, and cleaned underneath, no luck

 

I pulled it apart, thinking I could clean the keyboard, but the keyboard doesn't seem to be removable

 

Any other ideas?

 

Should I try to disassemble more of it to access the keyboard?

 

Thanks for your help

I'm afraid that the damage may already been done and will not be an easy fix.  You should have immediately pulled the power adapter plug and the battery when this happened.  Then you should have turned it upside down so the liquid could drip out.  But at this point this is akin to closing the barn door after the horsed has run out.

 

You can try dissembling the laptop to remove the keyboard to see if there is any liquid still inside.  But if you have had the laptop powered up I suspect the damage is done.

If you can get the laptop far enough apart to remove the keyboard & check that there is no liquid damage below it & you can source the correct replacement keyboard then yes you can replace the keyboard (have look on ebay for keyboards). This will only solve your problems if the damage is limited to the keyboard.

That seems to be a slightly different version than mine.  Mine is ES1 411 series

 

They don't make them easy to get into do they?

 

Will it be worth getting a professional to look at it?

Use a lint-free cloth to gently remove non-water stains. Use compressed air or a vacuum cleaner to blow away the residue. You may need to take apart the case if you cannot clean the whole spill. Some spills can damage the circuit boards.Use deionized water for water-soluble stains such as cola. Otherwise, rinse with alcohol then water. Make sure that the parts are dry.

On that model, you'ld be way smarter to get the whole top cover (keyboard, palmrest, and touchpad) Then, if you were uncomfortable with changing the part, pay somebody to do it.

If you're going to attempt a keyboard repair [or later a replacement], many keyboards are attached to their respective motherboards by a ribbon connection that is very easy to accidentally break -- take your time.

Years ago, I broke such a connection once, and the replacement part was another keyboard, not a motherboard as the retailer was trying to sell me   :)

Davis, you and I posted at the same time  :)   I like your idea much better than replacing only the keyboard.

Would thread starter still have to be very careful with the KB-MOBO ribbon connection assembly?

Yes, and it looks like there are three of them! On that model, the keyboard was stuck on posts which were then melted to fasten it to the back of the top cover. You undo all of the screws on the bottom, pop the top loose, disconnect the cables, and then it comes off.

A vacuum cleaner is a great static electricity generator unless it is one which was designed for this type of work.

You will need to be very careful with the connectors for the ribbon cables.  They are very fragile.

Yes but i instruct OP to disconnect the Keyboard and use the vacuum cleaner  on Keyboard i myself always clean my laptop keyboard and keyboard with vacuum cleaner even when its connected to laptop this will cause no ESD that will damage attached components.

Remove any liquid inside the laptop, and if you don't want to replace the keyboard, then you would have to do with USB or Bluetooth keyboard

Thanks everyone. 

 

I pulled it apart, as much as I could. Looks like I can't pull the keyboard off the top cover at all.

 

I couldn't see any spills.

 

I put it all back together, thinking it has to be completely dry now. Those keys still don't work.

 

So looks like I'll have to get that part. Do you know if there's somewhere I can get it from Australia?

 

I assume, since it's only a couple of keys not working, it means it's just the keyboard that's the problem?
