Laptop won't power up without battery - Overclock.net

money11465 · 10-27-08

My mother dropped her laptop and smashed the DC port in the process. I resoldered it and hot-glued it together, and it worked fine for a few weeks. Now, suddenly, it won't work again. It works with the battery just fine, but if I remove the battery, it won't turn on. Clearly a DC port problem. She needs to be able to charge it. What could be the problem? I glued it well, and I don't feel like dismantling it unless I'm positive that the inside part of the port was broken (you could actually see it rattling). This time, the port seems to be intact.

EDIT: Changed AC to DC. I'm too used to working with desktops!

What I like to do in case this happens is solder a set of leads on a board and get a coupler and do it externally.

Or track down a new port.

Are we sure the port is broken again? The first time, it was. But the second time, it suddenly stopped working without any trauma, and there's no visible damage.

It's possible your solder came apart? make sure

OK. It looks like I have to open it. Her laptop is a very tedious one to open.

A.) You will have to re-solder the DC Jack back to the motherboard.
B.) The DC Jack itself is borked and will need to be replaced (Pretty cheap)
C.) The motherboard itself is done for, the DC Jack actually sits through the board and is soldered to a few copper circular leads in the board. That part could just be bad and the board itself will need to be replaced (Pretty expensive)

I don't recommend trying to charge it any other way i.e. nothing external or 'jerry' rigged as this could be very hazardous. Good luck and I hope this helped.

*Edit* What model laptop is it?

are there any solder points that are touching that could be causing a short? why did u usse glue? was the d/c jack broken? it could possibly be an issue with the connection where the a/c adapter actually plugs into inside the d/c jack. either way go to laptopjacks.com and order a replacement.

also, i hope the glue hasn't melted and somehow caused a short on the mobo, cuz that'd be bad news

She has an Acer Aspire 5003WLmi, if I recall correctly. Like I said, the laptop fell on the power cord while it was inserted and pushed the center part of the DC jack out. I then resoldered the center part, and glued it because solder isn't for holding things in place, only for electrical contact. It works fine under battery, so the motherboard can't be bad. I had all of this info in my OP, guys.

Does the laptops power bricks light come on? How about the battery light on the laptop, does that come on when its plugged in?

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

Guide

That is a good guide, I have used it.
