Hi!
I've owned an HP 71B for almos 15 years now. I don't have any accesories except for the card reader. The thing is I think there's something wrong with it because it drains the batteries too often (4 or 5 days), and it seems to be independent of usage time. Everything works fine, the only suspicious evidence is that it seems to be beeping continously (barely audibly though), kind of a buzzing-heartbeat (it's hard to explain).
I will appreciate any comments that leads me in the right direction.
Thanks,
Carlos Frutos.

I can't da a complete diagnosis. Did you remove the card reader and check thid? There's surely something wrong, a working 71B doesn't produce such a sound. It might be a failure in the power supply (not the transformer, the internal power supply part in the 71B). Does the LCD display work? Maybe the DC/AC converter has a problem. This should be fixable. ▼
