i am having trouble with the "D" key. i dont know if you can call this problem "key sticking" because the key doesnt seem like stick. when i press the key, it pops back up like other key. sometimes when i press the key, the letter doesnt show up. i have to press it a few time.
and sometimes, it loops. like when i tap the "D" key, it shows ddddddddd. sometimes it keeps going non stop. then eventually it stops by itself. what happen? i use the screw driver to open the key, when i press the rubber, it pops back up like normal, but the ddddd are still going non stop then it stops ranodmly.

how can i fix it? it's a laptop, so i odnt think i can replace it easily. thanks
