      Guide Steps

      Step 1 — 记录原始BMS数据

      这种电池对于校准来说太麻烦了。

      Step 2 — 使用你的笔记本电脑

      不要对不可替代的数据做任何事情; 这将失去那些数据。只需插入笔记本电脑即可从BIOS锁定中启动它。

      Step 3 — 笔记本插上电源

      虽然使用笔记本电脑是安全的,但校准精度可能会受到影响。

      Step 4 — 校准后确认

      此过程可能会损坏接近使用寿命的电池。

      Step 5 — 电池健康状况检查

      如果容量不一致,请更换电池。

      Step 6 — (UEFI BIOS)HP 15% 锁定旁路

      这将使电池完全放电。HP 诊断程序不检查电池电量。

      Step 7 — (传统BIOS)HP 15%锁定旁路

      请勿将这些设置应用于主操作系统。它们可能会损坏你的电池。

      Step 8 — (错误0190)联想关键低电池旁路

      将电源适配器插入笔记本电脑。POST必须完成系统才能启动。

      Step 9
