Maybe too late now as this post is a few weeks old, I agree that as the last person to touch, it's your repsonsibility to fix / replace it. luckily this laptop is available on ebay for £100 avarage. I would always say to customers that all repairs are carried out with best endevour but unfortunatly, things go wrong and stuff can die, especialy old stuff, just like people can die during operations. As long as I did everything right and didn't spill a can of pop over the laptop, I would offer a good will 50% off the replacement motherboard from a used laptop.
