Having problems with your Dell Inspiron 1150 Notebook ?

Power issues or maybe motherboard going out?

\015 Okay I recently repaired a common problem on the Dell 1150 laptop which was the faulty AC jack. I soldered a new one onto the motherboard and it worked fine for a few weeks.However now the battery wont charge. Now I don't know if the battery is bad or not, but it also won't run on AC power for very long. I'm thinking maybe the solder came loose or my motherboard is going bad.I've experienced a lot of overheating of the laptop, which could contribute to either the motherboard going bad or possibly knocking the jack loose again. I took it apart but the jack appears to be firmly soldered down. I don't think the issue is the battery. If it was, then I should be able to run it on AC power no problem. That's not the case. Sometimes I can get 30 mins out of it and sometimes I can't even get it to turn on. I just purchased a new universal ac power adaptor to see if that could be the problem but I'm not getting any better results with it.Just wondering if there's any way I can figure out what the problem is without actually re-soldering the jack down. \015

Answers :

Hi there,
\015\012yes, I do that repair all the time. The key is to cleaning off all the old solder. The old solder can cause a bad connection. You need to get some solder wick, and some denatured alcohol. The wick will soak up the old solder.
\015\012Clean off the posts of the jack, and the circuit board from solder and flux, and use the denatured alcohol.
\015\012I know it is a pain in the **** to disassemble and reassemble, but it will be worth the time, and make is work right.
\015\012When you go to solder it back on, make sure you do not put too much or too little solder. A good shiny little bump on each one. If you have a good magnifyer, check out your joints before you assemble it all back together.
\015\012Good luck, and hollar if you need anything else on this.
