    Hey guys anyone know how to fix this?

    I heard all you need is a firmware update but don't know which one to get. The laptop is overheating and switching off. Others have said a blast of air would do it

    It's also out of warranty so I can't send it back

    Your fan output may be clogged. On the 1525, the fan sucks in air from underneath and disperses it out the side. There is a channel which is part of the fan unit which may be clogged.

    If you laptop overheats enough, it will shut down the laptop. Can you clarify that when your fan shuts down, does the entire laptop shutdown also?

    If it's just the fan that shuts down and not the laptop, this indicates a faulty fan, or the lesser possibility of outdated firmware. If the the entire laptop shuts down it is likely that the channel from your fan unit is clogged with dust & fluff. In this case a blast of air will not be enough to clear the blockage.

    The first thing I would do is to update the firmware. You should do this when the laptop has just been turned on from a cold state - you do not want it to shut down due to overheating in the middle of a firmware update.

    Your firmware should be release A17 - you will see this number when you turn on your laptop and you see the Dell screen & logo.

    If it's not A17, you can download the firmware update from here.

    Then install a free app called Coretemp from here.
    This will tell you what temperatures your CPU cores are running at. If it's operating above the high 70's or greater then you have an issue.

    Assuming that it's not the actual fan , but a clogged fan output, you will need to disassemble the laptop, remove the fan unit & output, disassemble the removed fan unit, and clean it carefully. When replacing the fan unit, it is good but not absolutely necessary to use thermal paste where the heat sink touches the CPU components.

    You can download the service manual with instructions on how to disassemble / reassemble your 1525 here.

    i'd say a good cleanout of the fan would sort it, probably dust jamming the fan and causing the overheating as mentioned
