Financial calculator issue

HP Recommended
HP 10bII+


I have bought the financial calculator HP 10bII + for a month. However, I realized the calculator was not working since yesterday. I tried to press the "on" button, but nothing happens. I don't think it runs out batteries. I do not know what to do, so can you guys please give me some feedback?

Thank you so much.

I'm looking forward your respond.

Pardon the obvious questions, but have you tried testing the batteries in another device, to make sure that they really are good?  (Not all recently purchased batteries are actually new.)  Have you tried poking the RESET hole (under the battery cover) with a paperclip?
