chargers tend to burnup, but so do batteries
to diag first remove the battery and have it hooked see if it starts up.
if it does the battery is shot. if not the charger or both..
click on the harddrive icon and check your memory, go to your recycle icon and find the empty button so you can get all that free space back.
macs are solid usually have no problems my household is full of them.
just check your free space and makesure you dont have too many programs running at one time.
if not take it directly to apple to diagnose and ask for an opinion on what to do,
depending on how old it is.
