Can damage the batteries or AC cause overheating?

I just cleaned my vents and fan and I still think that the laptop (Pavilion dv7 4000 series) is warm. When it works on battery it 75 - ish and when I plug the AC it get 85 + degrees. Is it possible that a damaged batters or AC adapter / CC causes much more heat? If this is not the case, what would it be?

If the laptop stops due to overheating, then yes it probably requires a repair. They would usually check the thermal paste/pad and fan to make sure it's working properly and that there is no internal blocking.

You could try a cooling block to see if this will help to keep your laptop cool enough to exploit.

You can also read through this to see if there's something more you can do: http://support.hp.com/us-en/document/c01657439

  • Can damage the FPGA module if I connect accidentally two pins writing together.

    My current configuration has a PXI chassis with two FPGA modules.  Each FPGA module has an adaptation Module 6581 on that.  I would like to test the signal through my system path by having the user to move some cables that would be a reason for a return to the other looping FPGA.

    I fear, however, the risk of the user is not correctly as shown and somehow a channel available in writing that connects to another channel write-enabled.  This damage to the FPGA or adaptation modules?

    Hi Brian,.

    Your concerns are correct. We never want to connect two pins that are output voltage. If two pins are outputs digital mistakenly connecting them together may damage one or both nodes in output since there is nowhere to flow the potential.

    It is well to connect to two pins that read a voltage. If both pins running entry digital (reading of the pins), as there is no risk, nor pin would be likely to be damaged.

  • X230T rigid hinge, can damage the display of stress?

    I just got my couple of X230T days and have been assessed. Performance and scalability is very good, but I find the poor build quality. Seriously, a cover blind on the slot of fingerprints?

    I found a major concern and you want to ask people if you guys have the same thing.

    The hinge is very steep (to be clear, he feels "rigid solid" and not "incredibly steep') and when I change to Tablet mode, the glass that covers the screen shows as if Gets a lot of pressure and it shows a few bumps on the lower edge of the screen. (EDIT: actually, it shows this same bump in laptop mode.) It looks like little by when you put electrical tape to cover two or three uneven surfaces together. It is not the effect on the visibility of the LCD screen or colors, but I'm just worried that one day the glass can break from there. There are actually two points along the bottom edge, but the photo shows only a right above the hinge.

    Please see the photo and tell me anyone of your X230T has that?

    This photo shows just the screen is raised a little on the top left corner.

    Think video drivers especially if it may be others. Refer to the section of driver in my credits
    methods of troubleshooting blue screen below. BIOS, chipset of low level drivers and
    antispyway/antivirus/security programs can also cause this. Check the resolution of the problems and

    BCCode: D1 0x000000D1

    Cause

    A driver tried to access a pageable (or that is completely invalid) address while the IRQL was too high.

    This bug check is usually caused by drivers who used a wrong address.

    If the first parameter has the same value as the fourth parameter, and the third parameter indicates a runtime operation, this bug check was probably caused by a driver who was trying to run code when the code itself has been paginated outside. The possible causes for the error page are:

    • The function was marked as pageable and was operating at an IRQL higher (including obtaining a lock).
    • The function call was made to a function in another pilot, and that this driver has been unloaded.
    • The function was called by using a function pointer that was an invalid pointer.

    Hi, Unclemarcus2002,

    You would be wiser to post on the Forum TechNet where there is COMPUTER experts.

    http://social.technet.Microsoft.com/forums/en-us/newThread

    Maybe using the ASSOC and FTYPE command in a script will do what you want? I think that these orders would also apply the association throughout the world, rather than on a per-user basis.

    ASSOC: http:

    FTPYE: http:

    Here is an example, that you can try.

    Let's say you have a text file called "foo.bar" and you want the extension .bar always open with Notepad. There is an association for text files, so get him by typing "Ftype | more' at the command prompt (it will make a major announcement). Finally, you'll see the line "txtfile". On mine, it's "txtfile=%systemroot%\system32\notepad.exe %1" without the quotes.

    First create your association: assoc .bar = FooBarText

    Now to assign your request to your file type association: ftype FooBarText=%systemroot%\system32\notepad.exe %1

    You should now be able to double-click the foo.bar file and it will automatically open in Notepad.

    If you already have a Microsoft Office Document Imaging association, I think that it should be relatively simple type of substitution. Use ftype /? for a little more help.
