My sister's friend spilled beer into her computer (Lenovo Ideapad U400) a few weeks ago and the proper measures for dealing with a spill were not taken. Hours later, the offending friend opened up the laptop to attempt clean it, but he didn't succeed.

 

Surprisingly, the computer is mostly working. The only problem I've found is that part of the keyboard is non-responsive (naturally, it's the part where the beer was spilled). As far as I can tell, the only way to fix this is by cleaning the residue off of the motherboard.

 

Here's where I'm stuck: I can't remove the keyboard due to the laptop's design, and removing the individual keys doesn't give me access to the motherboard (with the exception of a couple tiny areas under the spacebar). I tried getting at it by opening the back, but I quickly realized that would require removing too many parts to be feasible or safe. Does anyone have any suggestions on how I can get to the motherboard to remove the residue? Or other methods to fix this (aside from getting a USB keyboard)?

 

Note: I have already removed the battery and hard drive in anticipation of doing the work, and I've been sure to remain statically discharged whenever I was dealing with the laptop's internals.

 

Thanks for your help,

David

You need to download the Hardware Maintenance Manual - http://download.lenovo.com/consumer/mobiles_pub/ideapad_%20u300_u300s_u400_hmm_1st_edition_oct_2011.pdf - where you will find the necessary disassembly instructions - at your own risk!

Thanks. That guide confirmed that this is outside of my expertise; I took it to a professional today.
