Dropped my Thinkpad E420

A few days ago my friend tripped over the power cable or the network cable, I'm not sure which one, which caused my laptop to fall off my desk. It fell about 3 feet and landed on the corner of the screen which cracked it and it's now completely unreadable. It also cracked the part where you plug in the power adapter and bent the adapter itself. Amazingly, enough, it stayed on the entire time and after hooking it up to my tv, everything seems to be working ok. Since I'm a college student and don't have a whole lot of money, I didn't get the warranty to cover accidental damage so I'm planning on fixing it myself. The screen itself looks pretty straight forward to fix and I already ordered a replacement online. The adapter is what I'm concerned about. It still works, but it takes a lot of force to put in and it has to be sitting in an exact position or it won't charge. It gets kind of frustrating. I brought it to a local repair shop and they said it would be around $200 to fix, which I thought was pretty ridiculous but they said it was because they would have to take apart the entire computer to get to it. So before I start ripping up my thinkpad, I have a few questions:

1) How much is the adapter and where can I buy it?

2) How hard would it be to install myself? (I have some experience with building computers)

3) Is it possible to build a magnetic power disconnect? I have seen it on a few laptops out there (not the macs but custom design)

Here's some pictures so you know what I am talking about::

Hi Think_Maroon and welcome to the Community,

 

The link has videos showing how to take it apart and replace everything.

 

Open the link, choose Notebooks, Thinkpads, Edge, then your model. 

 

The power jack is mounted on a small sub-board with a cable that connects to the motherboard. 

 

http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0a60575_02.pdf

 

Here's your Hardware Maintenance Manual. Page 83 says what all needs to be removed to get to it.

There's also a parts list with part numbers.  

 

Ebay only has listings for the jack itself which would need to be soldered to the sub board.  It would be a lot easier to just get the sub board.

 

You will probably have to call service and get it through them. Have your part number handy to give them.

 

You will have to disassemble pretty much everything to get to it.

 

Dave

Thanks Dave. I was also wondering if you knew roughly how much it would cost to get the power jack fixed by lenovo by sending it in.

Re: Dropped my Thinkpad E420

I don't know, I always worked on my own stuff, but I'd be willing to bet that it would be a lot more than the quote your service guy quoted you.

 

You could call support and find out. They'll give you a quote over the phone.

 

If you're going to change out the screen yourself, you would already be about halfway there as far as disassembly to replace the jack.
