best to you.

Should replace key board. Moisture and keyboards do not mix.

If a tech opened it up and cleaned it, then you should be ok. If it was not cleaned, you run the chance of oxidation, which will cause corrosion on the metal contacts.
Was the coffee black, no sugar or cream?
And is also depends if there was sugar in your coffee. If it was plain black coffee, then you should be ok.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

After liquid spill the laptop has to be disassemble and the motherboard inspected for liquid damage. In some cases cleaning the motherboard might fix the laptop.



Check out this guide for troubleshooting Mac laptop liquid spills.

If you want to clean that touchpad, you have to dis-assemble your laptop which is very critical and you might damage the other parts or connectors. Ask for technical assistance near you.

Adjust the grind it is too fine.

Sorry to hear this,but if you are not technically minded then i would advise you not to do anything and just get it repaired.

You might be able to find a cheap replacement palm rest (which includes the touch pad) on E-Bay or similar site. Just search your model number.

As far as replacing it yourself, I recommend having someone that works on computers regularly doing it, unless you are completely comfortable working inside the laptop. If you are (and you take all necessary precautions), here is the Service Manual from Dell which includes disassembly instructions for the palm rest.

You probably fried something with the coffee.  There are replacement touchpads available if you know how to replace them if not an authorized dealer will be able to point you in the right direction.

If no operation after a few days the liquid did permanent damage to keyboard. Not uncommon.
