Hi my laptop packard bell easynote R4650 after about 20 minutes of use dies completely as if power has been removed ,It is worse when using alot of processsing power ie slide show of photos .Without really pushing the processor it will go for a couple of hours but eventually shut down.The fans are working and you can feel normal warm air it does not feel hot or overheated. you can restart straight away and it will work for a further 10 minutes and same again.progressivley getting quicker and quicker to shut down unitl you are unable to get past the normal windows boot up process through to desktop. A week before it started to do this the battery would show 100% charged but only give me 5 minutes of usage, but it still worked fine on mains. The battery does not charge at all now, not sure if this is related or unfortunate consequence. I have removed the battery pack just in case the battery itself was upsetting the laptop but run on mains it still just dies. There is no warning but is like i mentioned it is normally when you hear the fan slightly increase in level increaed processor use and boff it goes. I would like to order a spare part as my boyfriend would attempt a fix if somebody has the answer. help please cheers Louise
