Well, after my fight against Dell Israel and Omnitech, I decided to replace my keyboard my self. The keyboard was ordered via official Dell US website for only $13.99 (inc. P&P)
It took about a week to arrive and now I'm ready to start replacement process.
You'll need two wrenches like those.
First of all, you should shut down your computer and remove it's battery
Next, by using plastic scribe or small wrench remove front hinge cover.
After the hinge removed, you'll get an access to three screws in the top side of the keyboard and small plug. Unplug it.
Then remove screws.
After the screws removed, rotate your laptop by 90 degrees and pull the keyboard forward up to remove it.
Turn the keyboard upside down. You discover the plug, that connects the keyboard. Unplug it by pulling it up.
And remove the old keyboard. Now replace the old with new one and plug it back.
Put the new keyboard to it's place and push it down from the upper side and both right and left side to secure it in place. Do it gently to avoid scratches.
Replace all three screws and upper plug.
Put the hinge cover back by pushing it gently
And you done.
You just save $121.01. Not bad does not it? Thank you, local thieves, and know, who spares the bad, injures the good. However, here in Israel, an open door may tempt a saint.
Be good men and have a nice weekend.
