I mentioned the other day how the keyboard went in my laptop. (I have a Dell Inspiron 1545- it's about 3 years old now). It started Friday evening with just N and M not working. I used a dry toothbrush to clean the keyboard lightly, I even popped the keys off to clean underneath the ones that weren't working. Nope, didn't fix my issue. By Sunday it had spread to H, J, Y, U, 6 and 7. Arrgh. I ordered a new keyboard on ebay for $15 and free shipping Friday evening and it arrived today! Talk about fast shipping! (Seller I bought from is: hiparts).
All I had to do was take the battery out, remove 4 screws, pop the front panel off, remove the old keyboard, then pop in the new ribbon and keyboard. Took less than 10 minutes. Whoo hoo for a working keyboard again!
