I have a HP 2540p, and recently bought a new, extended accu for this laptop. It is a original HP battery, series HSTNN-DB23, part number 404888-221. The accu has a capacity of 83 Wh or 7800 mAh. This battery is supposed to be compatible with the laptop. It is a new battery.
However, when I use the battery, it charges only up to about 2/3 of its capacity - charging stops always somewhere between 66 and 70%. Then, the battery stops charging and upon hovering over the battery icon, Windows says "Plugged in, not charging". HP Support Assistant says something like "The battery is plugged in and is not necessarily charging". If I try to run the battery check in this software, it always crashes and stops working.
Has anybody ever experienced a problem like this? Is the battery simply too big for the laptop to handle, so the software limits the use of the battery? And can anything be done about this?

Thank you very much for your reply.
The lastest BIOS version was already installed on the device. Next, I followed the steps you propose (I had already done this earlier after a search on the internet, though in a slightly different sequence).
Unfortunately, it did not help: at this very moment, with the charger plugged in, the battery is at 66% charge and Windows tells me: '66% available (plugged in, not charging)'.
