Hi. My dad(he can't speak English:emotion-2:) bought very cheap secondhand Latitude E5500(just laptop, batterry and charger) but we have some problems...

1) We have some problems with multiplier regulating, it's hanging somewhere about 1,5Ghz(think it's c2d 2,4Ghz) and laptop is pretty lazy :( (tried another cpu, same) -- Mayble problems with NB or SB?

2) We tought that stock battery is dead, so we ordered new, but laptop is not charging! :( (tried adapter from friend's Vostro, my Inspiron 15z and brothers's ATG -- motherboard?

Thanks for your answers. :)
