Two questions when you took apart the laptop did you unplug the battery before you unplugged anything else? and also if you have a multi meter see if it pulls anything at all or anything abscure. if you are able to find a schematics for the laptop and figure out what those all connect to ex. main power/display and so on. The capacitors themselves are eaisly replaceable if you know how to microsodder. But if you can tell me what that chip is called and everything its connected too i can do some further research and help out more
