Open up a HP42s?

[Sven Olofsson]

How do i open it???

I will try to fix the B,C and D tabs in the keyboard.

I drill out the pins in the battery department and then bend it apart slowly but with quite some force until the lower pins snap. However, it could be a good idea to try cleaning it in an ultrasonic cleaner first, as that might save you from taking it apart.
