    Okay, HP sent me a new wireless card because of problems I'm having
    with the wireless indicator light. They did this under warrannty. I'm
    suprized that they sent it to merather than ask me to send it back to
    them. The guy described where it is. He said it was under a panel that
    had one screw This sort of coincides with what Jeff told me; near the
    corner near the hinge. I opened that panel and found a copper heat
    sink and under it was the processor. I stil am at a los for where the
    hel is the wiress card. I was really uncomfortable mucking with the
    intel processor.

    Unless of course the card that I saw under that panel was i n fact the
    wireles card. The card said 1.73 Intel (or something to that effect
    and that is what I have, a 1.73 G Hz Centrino. Any help is is geatly
    appreciated. I can call HP again but it will take hoursto get the
    right answer.

    I don't own this laptop, but I searched on the HP website and found a
    "maintenance and service guide" PDF that may be of use to you (link below).
    Section 5.8 (page 122) might be what you need.


    Good luck.

    Go to http://www.hp.com and download a copy of the Maintenance and
    Service Guide for your notebook. Look for the wireless mini PCI
    compartment in the guide.

    Or here's the whole secret:
    Look at pages 1-24 and 1-25.

    Chuck: Than you very much for tha tlink. i looked at the diagram and
    now I know hoe to procede. i was dissapointed to see that since I
    removed the heat sink and discovered the processr under it, I should
    have removed and reinsalled thermal paste. Not sure how bad it is
    without doing that, there is a certain amount of preload on ther
    processor form the heat sink screws.
    The guy from HP really missled me into removing the wrong panel.

    Thanks, I found the manual. My next question is how much damage did I
    do by removing the heat sink and reinstalling without cleaning and
    reinstalling thermal paste.
    If it blows up, as far as I'm concerned, it is HP's fault for
    insructing meto remove the wrong panel. Te sent me a card with no
    instructions, just remove the panel with one screw. They were wrong.

  7. I lied. That's the CPU. Unfortunately, of the two doors on the
    bottom of the laptop, HP put the CPU in the corner instead of the
    MiniPCI card as I previously indicated. Sorry.

    Close that cover and unscrew the large panel next to the bar coded
    serial number tag. It should have the MiniPCI card and memory
    See Table 1-11.

    I haven't used thermal paste in a long time and I'd really have to look at
    it to give you a good answer, but I'd say that you might be OK if the paste
    was still gooey. If it was dry and cracked, then it probably should be
    cleaned off and reapplied. From my experience with notebooks, they need all
    of the cooling help that they can get. Hopefully someone else here can give
    you a better answer.

    Actually I didn't realize ther was any paste at all. Wasn't sticky.
    I'm going to bet that it will be okay. The whole assembly seems to get
    compressed when I screwed dont the heat sink.

    I'm still going to bitch at HP for giving me a bum stear. May e they
    will send me some thermal paste to reistal the thing properly.

    There's an art to applying the thermal grease. The trick is to use as
    little as possible and only use it to fill in the gouges, roughness,
    and scratches in the metal. Wipe the excess silicon grease from both
    the CPU and the heatsink with a rag. Towel paper will work if it
    doesn't spew any lint. Use alcohol if it's slightly hardened.

    If you don't have any silicon grease available (Radio Shock carries
    it), try to re-use some of the excess that was already on the CPU. You
    may need to loosen it with a little alcohol. I don't recommend
    re-using silicon grease as dirt and dust in the grease causes big
    problems. However, as this is a new laptop, you might be able to get
    away with it if the grease is clean. Still, I strongly suggest you
    get some clean silicon grease heat sink compound.

    Put a very small amount of silicon grease on one finger tip and smear
    it on both the heatsink and CPU. Use as little as possible. Don't
    worry about slopping some over the edge of the CPU. You should be
    able to see the heatsink metal through the layer of silicon grease. A
    blob about the size of "BB" shot is about twice too much.

    Now, wipe the excess from your fingers or you will have white greasy
    spots on your new laptop. Use alcohol to cleanup. Keep the alcohol
    away from the plastic parts and labels or they will be trashed. Wash
    your hands or the alcohol on your fingertips may ruin the keyboard

    Put the CPU back and fasten the retaining clips or screws. Close lid.
    You're done.
