What could be wrong with the laptop battery?

Question

Batteries

I recently reinstalled Windows 7. I noticed that the battery only charges up to 45%, nothing further. I checked the charging, reset the BIOS, nothing helped. Thought it was a problem with the driver. But I could not find a power driver for my laptop: Acer Aspire 5749. Now I noticed that the battery is only charging up to 34%. And writes "connected, not charging." What could be the problem? Has anyone had this already?

Answer 1

It may be that the battery itself or its charge controller is dying. What nafig driver, the problem can be quite a hardware one.

Answer 3

Похоже подыхает батарея. Выкидывать ее не обязательно, можно отдать в ремонт - спецы просто поменяют в ней Li-Ion элементы, в обычной батарее ноутбука стоит 6 шт. типоразмера 18650. Если не все они сдохли - выходит заметно дешевле новой батареи. Например вот эти ребята давно подобным занимаются - www.li-ion.ru
