Re: Repairing HP keypads Message #3 Posted by Scott Buckner on 15 Apr 1999, 9:57 p.m., in response to message #2 by John
I recently purchased an HP-71B on EBAY.
To my dismay, 3 keys didnt work at all and 2 only worked if you would push very hard.
I took the unit apart and sprayed electronics cleaner into the holes three times to no avail.
I then tried a product we use at work called DEOX 2000 which is made to clean and remove oxides, carbon, and corrosion while leaving behind a contact enhancing film.
This worked perfectly after spraying them twice
This product can be purchased at most electronics stores.
GOOD LUCK!!!
