    Hi All,
    Just finished installing a replacement motherboard in this Inspiron M5030 laptop. The original problem was no power to laptop, no fan, no boot. Tried another known working Dell AC adapter i had and no luck with it. Tried removing Optical drive, Memory modules one at a time and ran diagnostic on hard drive after removing it and putting in another computer. Still could not get laptop to boot.

    I now have a different issue where i can not get a display on the LCD. I am able to hook up an external LCD and get the display to work on it.

    I was able to run the Dell diagnostics and im getting an error code of 0413. The code means LCD cable not detected. I reseated the cable and still have the same issue. The cable and connector look fine and none of the pins look damaged.

    Im getting what appears to be 2 different BIOS beep codes when first starting the laptop. The first one is a series of 3 short beeps, followed by 2 quick beeps and then repeats. This happens several times and then i get 8 beeps which repeat several times as well. Beep codes stop and it does boot to the Windows 7 login screen on the external LCD.

    Im able to stay at the Windows 7 Login screen without issue for over 15 mins. I have tried entering the BIOS to attempt changing the Service Tag, but the laptop shuts off after a minute or 2. Same thing if i hit F12 and dont make a choice.

    So something more than the LCD cable seems to be at fault here. Looking at the Service Manual from here: M5030 Service Manual its hard to tell if the LCD connector has a plug on the end that goes to the display. I hate to take the display all apart just to find out there isnt. Im leaning towards to it being a refurb lemon motherboard. Before i jump through the hoops of getting it replaced, i thought i would get someone elses opinion.

    Beep codes from m5030 manual found here: Inspiron M5030 Setup Manual

    Beep Code Possible Problem
    One - Possible system board failure or BIOS ROM checksum failure

    Two - No RAM detected
    NOTE: If you installed or
    replaced the memory module,
    ensure that the memory module
    is seated properly.

    Three - Possible system board failure or Chipset error

    Four - RAM read/write failure

    Five - Real Time Clock failure

    Six - Video card or chip failure

    Seven - Processor failure

    Eight - Display failure
