    My laptop's (Dell XPS M170) screen shut off the other day and I couldn't get the rest of the computer to shut down so I had to take the battery out and start it up again. Now my CPU fan is running at a high rate of speed and my computer is soooo slow. I did a diagnostics on it and got the error code: 3700:011B
    Msg: Expected processor fan on low RPM of 2500. Detected fan RPM =5345.
    I have only had it for just over a year. My warranty was up in April.
    I took it to Best Buy and they said to send it back to Dell and it was either going to be really expensive or really cheap. Wow- that helps me a lot.
    Can anyone tell me what you might think is wrong with it?

    Thank you so much

    Do you still have the user's manual? There may be some specs in that about fan speed.

    Also, check your BIOS Setup. There are usually fan limit settings or something like that.

    Note: When you disconnected the battery, you reset all BIOS setting to motherboard defaults which may not be correct for your Laptop as configured.

    For Laptops you should not remove the battery unless you need a new one. I am surprised you could even boot without the battery installed. Laptops we use at work must have a battery installed or they don't work.

    When I took the battery out, I put it right back in and started it up again. I just took it out to try and turn it off.
    I ran a diagnostic test today and got a message that the temperature sensor is out of range, temp=2500, min=10c, max=100c.
    The CPU thermistor, video thermistor and SODIMM thermistor all said the same thing.
    When I ran the video fan test, my computer shuts off.
