Bad motherboard The computer motherboard may be bad if your new and your old laptop battery won't charge and the laptop AC adapter is working properly.

Also, if your laptop battery will charge in another laptop, then that could be a sign that you have a bad motherboard. Battery is not charging at all or showing that it is not compatible The problem may be with the computer BIOS and an update is required for the laptop to recognize and fully charge the laptop battery. If your BIOS has not been updated, and Lenovo ThinkPad Edge 15 Power Manager have only used OEM batteries in your laptop, it can cause the replacement battery not to communicate correctly with the software in your system.


Some laptops have been prone to reject third party batteries if they have an old BIOS version installed. Once completing the BIOS upgrade, please recharge your battery for 12 hours and use as normal.

Battery stops charging before it is fully charged New batteries come in a discharged condition and must be fully charged before use.

For instance, on my Debian machine, I can clearly see an issue with my battery by simply looking at the Wh design and current reported capacities for the battery. Something here look fishy? One can think of Lenovo ThinkPad Edge 15 Power Manager hours as available power over time, whereas amp hours would correspond to current over time, and multiplying amps by voltage gives you watts. We could report in amps instead by using acpi advanced configuration and power interface as follows.

OK, so we know that there is something weird going on with the battery. Before I found the firmware fix, I was trying to diagnose this a bit myself. I used fwts firmware test suitewhich ran me through a process of plugging in and unplugging my machine.

This took about five minutes, while it tested the charge and discharge properties of the battery and compared those numbers to what the battery was reporting. This test reports which if any batteries there are in the system. Got interrupt s on GPE gpe Got SCI interrupt s.
