Ti-nspire high power consumption
« on: February 09, 2012, 04:36:25 pm »
I found my Ti-nspire working only couple hours on batteries. I've tried to check what's wrong. I've checked power circuit on the motherboard and it occurred that one chip is broken. I marked it red at picture. Does anyone know the type of chip. As I know it is responsible for voltage stabilization but I can't find similar to replace.
Thanks for any help. Best regards.

Did you drop your calculator severely?

I don't know why it happened.
I measured a current while the calculator was on and off (when power on 120 mA and off 80-90 mA - should be 0). I don't know the current when calculator was ok but i think it should be around 30 mA.
