[SOLVED]820-2879 not charging, battery detected but show 0% level

820-2879 not charging, battery is detected but always shows 0% level. Do you you have any suggest?
Second problem is that if I install 2 sticks of ram of 2gb each (2x2gb), macbook detects 1 gb for each slot(2x1gb). Is a ram slot dead? is there a fix for this?

macbook runs only with battery even if it show 0% level

Have you tried a known good battery ?

Is the machine stable with 2 x 2gb ram installed ? You tried known good memory ?

Could be bad RAM slots or MCP. Either way its a no fix.

both slot work, but every stick ram I install, macbook detects half of the size. no changes if I install in both slot or only one, it's always detected half of the size

Must use PC8500. Probably bad battery too.
