Also goto ebay, search the model of the laptop + dc jack.

Guide

That is a good guide, I have used it.

The battery light on the laptop doesn't come on, otherwise it would work without the battery in it. There is no light on the trafo. I can fix the DC jack, I have done it before, on this exact laptop. I'll open it up when I have time (not for a few days) and redo the work, and let you know how it goes. I was really only asking, under false hope, that there might be some other cause, because I didn't wantto open it up again.

All right, I decided to just buy a replacement jack on eBay for $6.00 instead of trying to glue it again and all that hassle. I will let you know how it goes.

The new jack arrived, and I can't desolder the old jack. I tried heating the old solder and mixing it with new solder and then sucking it up with a spring-loaded desoldering pump, but that will only get rid of about the amount I added. Desoldering braid will remove marginally more. I have a 15W-30W (tried both) switchable iron with a tip I ground myself, so it's very sharp.

I tried following these guides as well:

http://defectivekit.com/2007/02/15/g...it-yourselfer/ (though this one doesn't include good desoldering instructions)
How do I get the old jack out?

Bump.

Bump. I really need to get this laptop fixed.

You will need a soldering device that is a bit more powerful. Also replacing the DC port might not fix it, I've seen a lot of laptop mobo's which just can't recharge batteries anymore and then it's one of the internal circuits. I used to work at a laptop RMA department so I know it's not rare that a recharge circuit doesnt work anymore even though the DC port has been replaced.

Well, it runs fine on battery, and recharging is not the problem. I can live with it if it can't charge its battery. It just needs to power on. So, would that internal circuit you mentioned also stop a laptop from powering on via DC port without the battery? Furthermore, I soldered it once, and it worked. It would seem unlikely that that internal circuit would fry all of a sudden. Is that possible?

Bump. Also, would you recommend getting a more powerful iron (if so, how powerful?) or an actual desoldering iron?

I know I shouldn't bump so soon, but I want to order now. Should I get a 45W desoldering iron or 60W soldering iron, for the same price? I have a vacuum pump. Which of the two would be more effective?

Bump.
