My gf got this laptop about a year, and a half ago I helped pick it out thinking she might play games with me, and now It's having a power issue.
It will randomly accept power, and also charge the battery usually only after the device has been turned off for an extended period of time. Usually it will charge the battery to about 25% before it shuts off the charging, and power through the DC jack.
I first thought it was a software issue, but I've taken the battery out and had it directly on the adapter, and it was fine for about 15 mins then it just shuts off, and no longer accepts direct power. I tested the device on another charger inside an electronic store making sure it was within the specific standards. This also didn't work, but we got flickering as we put the DC jack in so I tired replacing the DC jack, and It's still doing the same thing.
So this leads me to believe that it's a mobo issue at this point. However this isn't the standard 5742G this one has the dedicated GT 520M which means instead of the replacement board costing 70 bucks it's 200.
I'm still thinking about calling Acer to see how much it would cost to have them fix it or see if they will do something even outside of warranty because it's less then two years old. I just think it's crazy a 600 dollar laptop having a mobo issue after only two years of minimal use.
If Acer doesn't give me an answer I like then my next step will be to take it apart again, and search for the issue and fix it. I have decent experience with soldering electronics, and diagnosing electronic issues, but I've tired to find some information about this specific issue, but there isn't much.
If anyone could give me some tips as to what I should be looking for, and what might be casing this issue I would greatly appreciate it.
I have also considered getting a stock mobo, and not worrying about the dedicated video card on account she no longer uses it for anything, but casual use however not sure if that could cause compatibility issues.
