I was using my CF-54 one day and I finished what I was doing then closed it. It has never turned back on. When plugged into AC power I get a battery light but that's it. This happened 2 years ago and went sent it for repair it needed a motherboard. This time it lasted 1 year and the exact same thing has happened. Is this a common CF-54 problem of eating MB's? Is there anything I can do myself before sending in for a MB replacement again?
