hp10bii+ turns itself off right after reset

HP Recommended
hp10bii+

First it turns itself off randomly. Its not connencted to a specific button. It can be anything. And it only turns back on when i reset it. But then it can either work properly for some time or simply turn off whenever i press something. Its about 2 years old so i dont think the battery is the problem, although i havent tried changing it. Ive tried taking the batteries out, nothing changes.

I on the other hand, highly suspect the batteries are getting low. Put new ones in and I suspect the problem will go away for you!   Basically, any time you press a key, the calcualtor wakes up from "sleep" (the screen is still showing in that state), it speeds up the processor, and does the calculation, and then goes back to "sleep". So if the battery can't provide quite enough juice, it may not make it through to the next sleep. Detecting low batteries is actually very tricky.

 

As the one who basically wrote all the software inside the 10bII+, I hope you've enjoyed it so far. 🙂
