I had a power problem with my Acer Aspire 5102 laptop.
The power plug would need to be fiddled with in order to work, once you found the right spot it would work great.
For about a week that worked, then it got harder. It’d take twice as long to find the sweet spot, then it would last 5 minutes to 12 hours and suddenly it was no longer charging.
I looked around online, and was told by a repair shop that it is definitely the power plug, Acers & Toshibas seem to have a problem with the power plug being crappy, he said to send it in & for $100+shipping he’d have it taken care of.
Well, for $400 I can buy a better laptop than what I currently have, so why would I spend 1/4 as much on a jack repair when I could just invest in a new laptop for that much?
I just kept putzing with the cord, (for about 3 weeks), while it kept getting worse, the cord needed to be putzed with at least once an hour to keep working, until today when it finally decided it would have no more & no amount of fiddling would work.
I have repaired XBOX & Wii boards for friends who were dumb enough to overheat them. This involves re-running a trace that been lifted, not nearly the same, but I’ve also helped them with their installations as well as repairing XBOX power supplies that had the built in fuse blow, so I figured what the heck, since I’m practically planning on throwing the machine away (not worth the repair & it won’t even function as a desktop), so I’ll fix it myself.
It was a massive pain to take apart. I’ve worked on Dells (upgrading CPU, general cleaning every 6 months or so), and while the equipment is junk (slow FSB, slow RAM, etc…) [at least the ones I've had to fix], the things are damn reliable & Dell is kind enough to provide a full break down set of instructions that show you every step of the way how to repair or replace anything.
NOT LIKE THIS ON THE ACER, I couldn’t find a manual, so I winged it.
When I get down to the motherboard, I notice solder splotches just about everywhere, the only reason for this is carelessness at the Acer factory, plain and simple.
Once I finally get to the power jack, I notice that 1 pin that’s connecting to the mobo is COMPLETELY BLACK, the only time I’ve ever seen solder like this is when you do a really really bad job soldering that results in a cold joint. So, I used some de-soldering braid & got all of the solder off (first you apply a new layer of solder, then you remove it all with the braid, don’t ask me why, but it works wonders), 2 of the other pins looked like the solder job wasn’t done very well either, so I de-soldered them as well.
I went ahead & re-soldered the pins back to the mobo, threw the battery in & low and behold! The problem is gone. I clean up the board using alcohol on swabs & more importantly removed the solder splotches that were all over the board. I finished putting it back together about an hour and a half ago, and its been running like new (while you’re in there, make sure you blow the cob webs out of the fans & heatsinks, you won’t regret it)!
Moral of the story, its not hard to fix, if your computer isn’t under warranty, consider fixing it yourself or having a competent friend who can solder take care of it for you.
