..possibly a short in the power cord. Usually, it's a short at the computer's jack. Since you didn't tell us, I'll guess the Kogan techs are using a different power cord when they're doing the testing and as such, it might be the power cord but only testing with a new power cord would tell.
In the meantime, please try this and see if it helps. I doubt it, but it's worth a try. It's a two step process.
Uninstalling and reinstalling power management software in Windows:
In order to correct problems with the battery's power management software, follow the steps below.
1. Access the “Device Manager” .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
4. On the Device Manager taskbar, click Scan for hardware changes .
Alternately, select Action > Scan for hardware changes .
Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. Restarting Windows will have the same effect of letting Windows re-recognize the hardware and installing the correct drivers.
If that doesn’t fix it, then shut down the computer, unplug all power cords, remove the battery, then depress the power button for 30 seconds. Replace the battery making sure all connections are solid, then plug in the power cord. Hopefully things are good.
Hope this helps.
I've got a Kogan Atlas UltraSlim Pro (KALAP13SPZA) running Windows 10 Home. I originally bought it last October, had it replaced 3 times so far because each time I've received it there've been issues with charging/the battery just straight up refusing to charge - a constant has been that if the laptop is turned off while it's plugged in, it'll register as "plugged in, not charging" when it's not plugged in.
Previously, plugging it in and then unplugging it would solve this, but this time it keeps registering as being plugged in when it's not. On top of that, if I rotate the cord a little in the plug it flickers between charging/not charging.
I feel like I've done a terrible job at explaining what's happening, so here's a video:
Kogan assured me that this time they checked everything to make sure it had no problems before they sent it off, but this same issue is happening again immediately. If anybody knows any fixes or maybe any reasons as to why it might be happening I'd really appreciate it. If there's a way to avoid sending it back again that'd be awesome - I've been without a computer since October and it's really set me back in terms of schoolwork.
