Hello, I would like to ask... I have Toshiba Satellite C50-A-1FX Laptop which has Pentium 2020M CPU. Can i upgrade that notebook with i5-3210M or i3-3110M? Also there is a strange thing about the notebook... he doesnt turn on with battery... when battery is not installed everything works perfectly fine, but when battery is plugged in i got black screen, even on second monitor doesn't show anything. Thanks for your answers
