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: http://support.dell.com/support/edocs/systems/insM5030/en/sm/display.htm#wp1109848 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: support.dell.com/.../index.htm
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
I am Nikul same here problem for the my Dell Inspiron M5030 laptop.
Sorry Nikul never got it working. Replaced motherboard as i said and also the cable for the LCD and still no luck.
Good luck with your repairs. Please post back if your able to get it fixed.
Sorry to say that my M5030 did the exact same thing a week ago, waiting for ideas from DELL but looks like you have tried everything. If I hear differently will let you know. Good Luck!!
Try the oven trick here:
Worked for me. Left it to cool overnight.
Seven Beeps is Not CPU Failure its Gpu failure in my experience and can be fixed by using a soldering heat gun to re-flow the chip as a temporary fix sometimes permanent
I was trying to replace my hard drive and after I turned on my computer it gave me 7 beeps signifying a processor failure. I have a dell inspiron m5030 and was trying to look for maybe a replacement part without spending $150 is there a way to find it cheaper maybe...
