Well a few weeks ago i spilt a whole glass of water over my macbook. I tipped it upside down immediately to tip the water out, and it turned off. I then turned it back on to save my work as I am at uni and couldn't afford to use it (I know that was a really stupid thing to do but I didn't realise at the time...) I took it to the apple retailer and they said it would be a write off so I bought a new one straight away. However I turned the water damaged one back on after drying it by the radiator for a week, to find that it works perfectly... apart from one thing... The battery does charge, but extremely slowly. I left it plugged in overnight and it only got to about 30%. It also loses charge too quickly when turned on. Now what i want to know is, is this a problem with the motherboard, or the battery? I put the macbook on ebay saying that the battery just needed replacing, but was informed by another ebayer that it could in fact be the moterboard. I was wondering if anyone knows if there is a way I can check myself if it is the battery or the motherboard? I have tried resetting the pram and the system management control with no luck. Would be really grateful of any advice as someone wants to buy it but I would really like to be able to tell them if the problem is with the battery or logicboard because obviously it will make a lot of difference to the repair!!
