Dragonfly plugged in not charging

[ineram]

Hi all,

I'm having a problem that I've seen described here a couple of times, where the battery status indicator says "plugged in", but the battery is not actually charging.

I've had this problem twice before, once it sort of resolved itself after a while (I thought the battery was faulty or something and I was on holiday, so I figured I'd just have to get a new one when I got back home, but by then it had fixed itself, although it would still charge sporadically at the time), the other time I applied the fix with uninstalling the ACPI-Compliant Control Method Battery, and that worked.

This time, however, none of the solutions appear to work. Battery check indicates that the status of the battery is fine, the adapter seems fine, as it does keep supplying power, unplugging it and plugging it in again or using the other port does nothing, and the fixes suggested in the other threads also do nothing.

There's no more updates waiting to be install (there were before, but I've installed them now and it changed nothing), and I had a BIOS update quite recently (which is possibly what caused the issue?).

Any other suggestions I could try? I'm leaving on holiday soon, and I will definitely need to use my laptop without the charger plugged in, so I really need this battery to charge.

I've run the power diagnostics from the F2 menu, both battery and adapter are OK, but it does say it couldn't determine the charge of the battery?

Take a read of the article I wrote for the notebok Knowlegebase adressing the very same issue you are faced with.

It provides a method of seeing what the state of charge of your notebook is compared to the original factory design charge capacity it in Watt Hours.

I had found that article, but it didn't really tell me much more. The full charge capacity is indeed quite a bit lower than the design capacity, but that doesn't really seem to be an issue.

I've reapplied the fix of shutting it off, unplugging the cable, holding the power button for a minute and then turning it back on again and plugging the cable back in, and somehow I must have done something different than the last 5 times I tried it, because it seems to be fixed for now.

I think the trick was not to plug the cable back in until the computer was properly restarted.

But this time after holding the power button for a long time, the screen also went black and showed a huge icon of a depleted battery, and then when I turned it back on again, it worked, where it didn't the last few times I tried it. Fingers crossed it stays fixed now...

How much difference in capacity between factory full( in watt hours) and current full charge(in watt hours)?

[ineram]

It's at 71% of design capacity.

But everything is working fine now, batterywise, problem is fixed. Unfortunately, now my brightness adjustment keys have stopped working... Argh... I suspect a recent Windows update is to blame, yet again.
