Keyboard Failure due to Moisture

As you have done, and I would suggest to anyone with the same problem, just replace the keyboard. You can get them quite cheap and in used working condition from some of the online auction sites.

 

Most of the Acers laptops will have a couple of screws on the bottom that hold the keyboard in, possibly. Will also need to remove the hinge/power button cover between the keyboard and the lcd. Might have some screws holding it in from the bottom, might not, also check under the battery at the back for any hidden screws. It may simply pop off and on... then you'll possibly find two screws under that holding the keyboard in. Once the screws are out, simply lift it slightly to find where the ribbon cable plugs in. And gently lift the locking latch on the keyboard plug. The ribbon will then easily slide out. And simply do the reverse to install the new one, making sure to push that plug lock back down.

 

This is just a generic assumption, as I am not real real familiar with the 5570, but they are all alot alike. Also note, when removing the power button cover, just in case there may be a ribbon cable under it attatching it to the mainboard, if you pop it off, look under it before pulling it too far. Wouldn't want to rip a cable if there is one there.

There are four screws that need to be removed, two under the battery (not the one closest to the edge of the Notebook), and two at the rear end at the hinges. The two at the hinges have a small cover over them held in place by adhesive, just lift them off with a sharp object. Removal of these screws now enables you to remove the cover between the keyboard and screen, also covering the hinges. Once this has been removed, there are two slides on the keyboard, one between the 'esc' and 'F1' keys, and one between the 'Ins' and 'Del' keys. Simply use a small flat blade screwdriver to slide each block towards the '1' and 'Backspace' keys respectively. The keyboard can now be lifted (carefully) and pulled away. To unclip the ribbon cable, carefully lift the clip over the ribbon cable - it is hinged. Replace the keyboard and reverse the procedure to fix it in place.
