HP 48GX - Low batterie alarm


For years I own a 48GX. It always worked fine until this morning.... I got a LowBat(s) alarm even after preplacing the batteries. (Yes I checked, these were new and full). I consulted HP Netherlands but it seems they can open the calculator but will not be able to close it again.... (They said it, not me..)

Does anybody know a remedie?





Maybe the battery contacts of the calculator are not OK. I would check for corrosion and make sure the contacts are pushed hard enough against the poles of the battery by GENTLY (!) pushing or bending them a little.

good luck


a newly purchased, but used, 49 did the same thing until it was reset, so you might try that.
