IMHO this corrosion (Cr metal extension of the battery-compartment, and Cu on the motherboard) can be avoided by using golden contacts like in the rest of the hardware industry.This guidebook applies to software version 4.0. My Texas Instruments TI84 Plus works again for 100% I tried to clean the corroded parts, but the thin metal was corroded away, so I bent the two flexible extensions from the battery-compartment a little bit sideways, so they could touch a fresh, non-corroded part of the* + and - entry spots on the motherboard. So the power was no longer connected to the + and - entry spots of the motherboard. Immediately visible was a tiny but fatal corrosion on the two little metal-covered spots on the motherboard, where the metal extensions from the battery-compartment (the backside of TI84) touch the motherboard (frontside).

Once the screws are unscrewed, I used my nails to unclip the two parts. I removed the 6 torx-screws, and removed the backside (battery-compartment) from the frontside (screen and motherboard). TI 84 Plus is dead (yesterday alive and kicking),.
