HP 33E - died?

[Steve Simpkin]

You said you plugged it in. Don’t use the AC charger unless there are known *good* rechargeable NiCad or NiMH batteries installed and all contacts are good. The batteries in Spice and Woodstock models are used to filter and provide voltage regulation of the unregulated output of the charger. Better yet, never plug in the charger to be on the safe side. Try running it on batteries.
