I recently bought a new battery for an hp pavilion 17 running windows 10. The laptop wouldn't turn on with the battery plugged in, so i assumed it was wasn't charged. When i turned the laptop on with the AC adapter, it showed the charge percentage at 72%, and that the battery was charging, once it reached 100%, it showed the message Plugged in, not charging. However when i tried to run my laptop using the battery alone, it still wouldn't turn on. I assumed the problem was with the battery, so i ran a few tests, the battery report generated from powercfg /batteryreport showed both total capacity and current capacity to be equal, around 35000mWh. I installed BatteryCare, and it showed the same result with wear level being 0.00%. I wasn't sure what to do, so i plugged my old battery and to my surprise it showed the same results as the above, meaning it wasn't damaged at all, and there was no need for a replacement. So my question is, is there still any chance that the battery is damaged, or is my laptop at fault, in which case how can i find out what's wrong ?

  • With the old battery plugged in and charged, can you run the computer without being plugged in to AC? If so, I would suspect something wrong with the new battery; if not, I would bet on a problem with the computer. Apr 9, 2018 at 11:53
  • Also the new battery can be perfectly fine but not correctly recognized by the firmware (BIOS or UEFI). Some manufacturers use several "tricks" to prevent the use of non-genuine parts.

  • @JeffZeitlin the old battery is at 0%, and it's showing "Plugged -in, not charging". I've tried to get to work for a while but couldn't, that's why i bough a new one. Apr 9, 2018 at 17:55
  • @MichaelBay how can i render it recognizable by the firmware ?, if at all possible Apr 9, 2018 at 17:56
  • If genuine it should just work; if not it may not be possible. Sometimes a BIOS/UEFI update makes it works, other times it's the opposite. And another possibility is the new battery not being compatible for some reason. It may fit but not work. Some years ago a co-worker found out that for a certain Compal line of laptops, batteries looking exactly the same were not interchangeable between models.

    I'm afraid it didn't work, nor did a few variations of this trick. I'm just going to conclude that it's a hardware issue. Apr 13, 2018 at 11:05
