More likely, it was a process decision. They most likely wave-soldered
the board, but the switch side has gold-plated switch contacts, so they
couldn't wave-solder that side. So, to put a few components there, they
used the adhesive. (The alternative would have been to hand-solder SMD
parts on that side, and I'm not aware that HP ever did that.)
Best regards,
Charles
