Let me make a general observation. At one time I felt very confident about repairing computers myself. However, when it came to laptops, I was not as successful. There are so many variations and laptop design that it's quite easy to make a mistake and damage something. However, replacing the hard drive in the laptop is not a major chore.
Based on my own experience, this is what I generally recommend for anybody that wants to work on a dead laptop.
First of all find out what the computer is worth and replacement parts and make a judgment. You may also find a perfectly good used computer of the same make and model with a warranty that sells for less than the cost of the parts. Do the math. Let me say that again, do the math. In my opinion you could buy a used or refurbished laptop from a vendor that will offer you at least a 90 day warranty on the computer. If it doesn't break in 90 days, it probably would last even a year. The computer you have probably has some value as parts. You may find a buyer this willing to buy your computer and pay you for the parts. That will offset your cost of buying a used refurbished computer. I am estimating that you end up saving more money by buying the refurbished computer and then selling the parts of the old computer.
My reasoning for this is us as follows: the people who do refurbishing do it in such a large scale that they have the advantages that you and I don't have. They have access to equipment, they have access to suppliers, and they have on hand trained technicians that have already done this before. They can refurbish the computer and sell it for profit for less than what you can. In my humble opinion.
I have purchased refurbished computers on eBay and all of the computers I have bought over eBay did work and were as described by the vendor. Now some of the other things I have bought on eBay were not always that well represented, but the ones that sell refurbished computers usually are straight dealers and they will not sell you junk.
So that is my recommendation. Go find the same make and model on eBay, locate a vendor with a reputation, and buy from him. Then try to sell the parts you have. There are some people that will buy the parts off of eBay thinking that they can repair a computer themselves. People who are just as confident as you are. But you have an advantage, you consulted with other people and got their opinion and you know better now.
