Swift 3 SF314-52G-59DZ Not Charging

Hey guys,

Owned a Swift 3 14" with an 8250u, 8GB RAM and an MX150 for 2 years now, and after many little issues, finally had one big one. It no longer charges. When it still had battery power, it didn't say 'plugged in - not charging', it would just not charge.

I have seen other threads with the same issue, and I've tried lots of workarounds, including:

Checking AC Adapter drivers in windows
Pressing down Battery resent pinhole on bottom for 30 secs
Trying a new AC adapter
Trying a new charging port that connects to the motherboard
Trying a new battery
Multiple different combinations of all of these.

Nothing has worked, it still wont charge. I was lucky that the battery I had purchased arrived with some charge, so I was able to boot it up and remove some files, but that is now dead too.

Has anyone made any progress with this issue?

Kind regards,

Reeve

Yeah, they typically sell fewer of the discrete GPU versions, just due to the additional cost. That means it's usually a lot longer before you start seeing used parts on the secondary market.

The Acer part number for your motherboard looks like: NB.GQT11.002, the i7 version of that is: NB.GQT11.004. (001 and 003 are the 4GB versions instead of your 8GB). Maybe those numbers will help in the search. There are also compatible MBs with 7th gen CPUs installed, NB.GQN11.004 and NB.GQN11.006 for the i5 and i7 versions.

First of all, which Swift 3 model do you have? It should be something like SF3xx-xxx-xxxx. The battery reset is more than just pressing the switch through the pin hole, but the new battery would have bypassed that is it were the issue. Was the replacement AC adapter the right size? Many of the third party adapters have an inside dimension of 1.35mm instead of 1.1mm, which leads to a lot of flakiness when trying to charge.

The one thing that I can think of that you haven't tried is the motherboard itself... The charging circuit is on there and it deals with using the battery sense connection to allow charging voltage through until the battery comes to a full charge, then stopping the charging until it's down to a certain level. It might be stopping it all the time... You might be able to use a VOM to measure that.

It's an SF314-52G-59DZ, and I'd managed to get a genuine adapter on eBay which fit both the old and new charging port great. I'm thinking along the same lines as you unfortunately, something wrong with the charging circuit on the mobo, which is real bad news as I'm in the UK, where they barely sold any 59DZ with the dGPU and i5 (I waited 4 months for this ONE to be for sale XD), can't find motherboards for sale anywhere

Those part numbers are super helpful, thanks! I've just picked up an XPS 9310 (Many of its own issues, as it turns out!), so I will likely wait around till I see a compatible mobo pop up for sale used so I've got a spare laptop sitting around.

Cheers!
