Question Battery won't charge beyond 86% on new laptop ?

[Delllx]

Hello, I bought a new Gigabyte Aorus 16X 9SG Laptop 2 days ago. I replaced the ssd and ram modules, but there were black foils (probably a seal?) on the two screws in the middle. The laptop works perfectly. I'm happy with it except for the charging. Unfortunately I didn't notice the charging problem until late. When charging, this gets stuck at 86%. In the bios I switched from ,,test" to ,,production" according to other threads but that didn't help. Next I reinstalled the battery status indication drivers in Windows 11 and it only helped from 86% to 87%. I have the GCC control center set to full charge. Is there anything else I can try? It doesn't look like a battery defect to me. In Windows 11, at 87% it shows that some battery protection is running. Is battery protection still installed elsewhere? I couldn't find FlexiCharger in the bios. So, I'm asking for advice or opinions from more experienced people. Thank you.

Bios: Updated to the latest version. GCC: latest version Age: purchased 2 days ago.

Btw. Now I'm trying to drain the battery completely. I have fast charging on in the bios (to avoid protections) and I'm waiting for it to charge when it's completely empty.

Welcome to the forums, newcomer!

After powering down the laptop, disconnect the laptop from the wall, disassemble the laptop, disconnect the internal battery, press and hold down the power button for 30secs to discharge any residual power. Then reverse the disassembly process and then see if the battery charges/discharges as it should.

Thanks for the advice. I'll try a similar procedure overnight. I've also prepared a script for logging the charging/calibration process. The Battery Report shows a design capacity of 99 Wh, but a full charge of 89% only 71 Wh, and at 89% it's currently only maybe 66 Wh. I'm also wondering if it needs some kind of buffer or something 😀
