Re: HP 21 keyboard Message #4 Posted by Andrés C. Rodríguez (Argentina) on 24 Oct 2001, 7:23 a.m., in response to message #1 by pierre VOINOT
You can find previous postings here about how to clean contacts with alcohol, compressed air, etc; or brushing with a tiny piece of wire. Read the postings before doing any work.
If possible, avoid breaking the posts. If you need to cut them, try to do it in a manner that allows for subsequent glueing or otherwise sealing them when you are finished.
Many years ago my HP25 was fixed by the then "official" HP service in my country (there were no HP offices here at the time); they cut the top of the posts, and the keyboard became somehow loose, losing some of the original feeling.
