I was reading the reviews for the HP 15C LE on the HP Home & Home Office site, and came across another negative review, due in part to another misinformed tech support person:
"Try the self diagnostic. Error 9 every time. Called technical support. Was told this was normal for this new calculator. Nice job whoever wrote the new manual."
Although the revised Owner's Handbook (Edition 2.4, Sep 2011) has corrected the self-test information on page 261, it still lists "Error 9, Service" on page 207 with the description "Self-test discovered circuitry problem, or wrong key pressed during key test."
Clearly, this is no longer valid, yet it still appears in the manual and tech support is still oblivious to the whole situation. This is the second instance of a bad review that is the result of incompetent tech support. Frankly, tech support should be instructed to read the following text when asked any technical question regarding the HP 15C LE:
"I am a clueless minimum wage cretin who can't give you any useful information on this product. What did you expect from a company that hired a former eB** head as its CEO?"
