    Question Hardware-Toshiba Satellite T235

    I work for a small healthcare provider as one of 3 IT personnel in charge of 11 networks in their nationwide company. We have an end user who has a Toshiba Satellite T235 that she says overheats and shuts down ONLY when she's operating on batter power on an airplane. We have replaced her battery and it was fine for a while, then the issue returns. Has anyone ever seen anything like this and if so do you have any idea what might be causing it? Any help would be appreciated.

    The only thing I can think of is that she is blocking the cooling vents somehow while using it on the plane.

    I would be looking at something in the laptop, perhaps the P/S that is heating up. There might be some short somewhere in the laptop that is drawing the battery voltage down and causing the overheat situation. If you do not have any competent tech people to tear down the laptop, it might be worth taking it to a tech. to have it looked at, or if the age is such, it might be time for a replacement.

    As Jerry says it could be user error. I always use a hard surface to use my laptop. Soft surfaces tend to allow the laptop to sink in too far and block the air vents. Have he try to use the drop down table on the plane.

    Install a temperature monitoring software and have her physically describe where on the device she feels the heat. [exactly]

    Thank you for feedback

    Thank you all for your feedback.

    1. She IS using the drop down table on the airplane.
    2. It's a fairly new laptop, so age is not the issue.
    3. If it was dirt in the vents wouldn't it happen all the time and not just on planes?

    A friend mentioned the trouble that Boeing is having with the batteries on the 787 and the fact that they are normal on the ground but heat up at altitude. Could this be a related issue? Is the cabin pressure on a commercial airplane the same as ground level or is it higher?

    I will see about installing the temp monitoring software to see what happens. Unfortunately the end user travels a LOT and it's hard to get hold of the laptop to physically examine it. I will endeavor to see if we can get our hands on it.

    I didn't mean dirt in the vents but somehow positioning the laptop so the vents on the bottom of the laptop are blocked.

    Interesting. If that is the case I doubt there will be anything she can do about it.
    Limit use of laptop in flight and closely monitor temperature by physically "feeling" battery.

    Thank you for the advice, we are attempting to get the latpop in our hands to investigate the hardware. I will pass on the suggestion of monitoring the battery temp.
