You can but try... It's possible that there's some firmware control of the battery circuit, though I would have suspected something more on the electronics side. Especially when a device supports different sized battery packs. My old laptop's batteries plugged in via a multi-pin connector, so there's more than just positive and negative battery terminals, there's also some monitoring features. Even if charging is controlled by the device, batteries often have some circuitry inside them as well. It's also entirely possible that your new battery pack came faulty. And it's also possible the laptop was faulty, the initial problem of the battery only partially recharging mightn't have been due the original battery. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
