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
We had some Acers do the exact same thing and we fixed them. I believe it shuts right off as a safety. Usually when the processor gets too hot it powers right off to save the laptop from burning up. First quick fix it to blow out the vents and especially blow out the heat sink vent. Also could be that the heat paste that sits between the CPU and Heat Sink could have dried up and stopped doing it's job to remove heat efficiently from the CPU. Big problem in earlier model Gateway laptops too. This can be fixed by acquiring some paste from a local tech shop and reapplying it. If you feel unsure about it, take it to a tech shop and they can do it quick for cheap if not for free. Keep me posted - Scotty
