7 Beep Error on M5010 Laptop

I have the unfortunate situation of owning a Dell Inspiron M5010 Laptop. Only 2 and a half years old. $1000 computer.

It will not boot up and gives the 7 Beep error. I had it checked by BB where I bought it
and they changed the coin memory Battery , Ram and ports check out OK. Cost $60
BB advise the Mother board is defective. I spent the better part of 2 hours on the
phone directly with Dell Customer Service and their out of Warranty Tech Support departments.
They were unwilling to give any Support or any sort of discount on having the Mother Board replaced. They wanted $300 to replace the Mother Board and $50 shipping each way.
What idiot would pay $400 to replace a mother board on a 2 year old computer.
I can buy a new one for that. I believe a new mother board is about $150 to $200 + shipping.
Customer Service would not even give a discount on shipping me a new mother board, when Dell fully knows that their Mother Boards are DEFECTIVE.
Look up Dell 7 Beep error on internet and on the Dell website for all the other people out there that have the same problem with this exact computer and other Dell models.
Everyone is complaining about the same problem, Dell have threatened to remove all my posts.
This is the second Dell laptop in 6 years to quit working.
Next step is the Better Business Bureau to file a complaint against Dell.
