    Hey everyone,

    What:
    I have a Vostro 3700. I've recently replaced the motherbaord/heat sink/fan due to overheating issues. (I had the integrated Intel card and the discrete NVidia card.) Once I received the newer motherboard I found out it only has the discrete graphic card and the Intel is no longer available. Come to find out the previous mobo is no longer available. Goodbye, 7 hr battery life and hello 4 hr battery life!

    So I put everything together, no extra screws or parts, everything fit like a glove.

    Powered the thing on, set the asset and other tags along with BIOS settings. Everything works great. BTW, the new Loctite thermal grease is awesome and now the temp on idle is around 40 degrees... awesome. Much better than the 55 degrees at idle.

    So I put my laptop on suspend, to ram, not hibernate. I wait for the power indicate to flash showing it is in suspend. As I place it in my laptop bag... I notice the power indicator isn't flashing like it was.

    I pull it out and turn it on and sure enough... it was no longer on suspend but the laptop starts anew loading my OS of choice, as if it was shutdown instead of in suspend.

    I go ahead this morning and disassemble it and reassemble making sure everything is nice and tight and cozy... I turn her on and suspend again. I then start pressing everywhere on the casing to see if I can recreate the problem...

    Where:
    When I press on the plate directly in front of the battery that has the processor, memory, Wifi, HD and the CMOS battery... the laptop is no longer on suspend. I suppose the memory is shorting out when that area is pressed and causes the memory to loose its juice... i.e. gets out of suspend.

    Can others with the Vostro 3700 test this to see if I am the only one having issues? I probably need another replacement mobo to resolve this issue but I wanted to be sure before going down that route again.

    How:
    Howto recreate the problem:
    1. Turn on your laptop.
    2. Place in suspend to ram. Do not hibernate.
    3. Close the lid and turn over.
    4. With the power indicator toward you, locate the housing plate in front of the battery.
    5. Gently press on the plate in from of the battery.
    6. Monitor the power indicator light to see if it stops flashing.

    BTW, even though I am DCSE certified, I went ahead and followed through with the tutorials that Dell has on the Vostro 3700:
