Hi all,
I bought this mini PC last year and used it just a few times, when I go to some customer I’m using it in order to have a quick, light and easy device for presentations and company office file.
I suppose to have charged the battery 25-35 times at all. In a year. But I’ve noticed in these last times I’ve used it, that the battery has got crazy…
I fully charge the battery in the evening while the Ubook is off. The morning after, I turn it on and noticed that battery is 7%…
Or, I charge it fully then remove the cable. In 5 minutes, the battery goes from 99% to 91%, to 83%, to 68%… In a few minutes. Then I turn it off and again on after a few minutes.
And Windows informs me that the battery is low, 7% - 9%… I need to work every time with the charger.
It’s a disaster. Now I’m trying to understand with Amazon if it’s possible to obtain a new battery but I’m not sure that it’s only the battery the problem.
Anyway, do you know why this behavior? I’ve used just a few times this laptop. It looks new ! Which is exactly the code / model / brand of the battery in the case of exchanging it ?
It could be a runaway process eating up CPU-resources, but since the Celereon in the Ubook Pro is so power-efficient, I doubt that very much. More likely is the battery itself deteriorating and not holding a charge anymore.
Can you see any swelling on the back of the Ubook Pro? Several members of this forum have reported their battery swelling up after a certain amount of time, sometimes even just weeks into using the device.
Look around on the forum, there are links to OEM-batteries for the Ubook Pro. It’s really not that difficult to replace.
Batteries can of course deteriorate without inflating. It could be a calibration error, making the tablet “think” that the battery is fully charged while it’s not. Letting it fully deplete and sit for 1-2hrs and then letting it charge for a full day might fix that. Pulling the plug (of the internal battery) and reinserting it after waiting 1-2 days might as well.
