1. Battery (natch)
3. Circuits on mainboad.
We don't need to turn on the laptop to charge so we need to know more about age and story.
PS. 2+ year old batteries are not to be trusted.
I have a Toshiba Satallite Lap Top a105 -s4002
It won't charge the battery. Neither the old or a new one. Is there any way to repair this type condition?
