***''++IMPORTANT:++ ++HP LAPTOPS CAN BE CALIBRATED USING THIS METHOD, BUT IT IS NOT THE RECOMMENDED METHOD FOR "UEFI" HP LAPTOPS++ - THESE SHOULD BE CALIBRATED WITH THE [link|https://support.hp.com/us-en/help/hp-pc-hardware-diagnostics|HP UEFI diagnostic tool] IF POSSIBLE. This method works in lieu of using the HP tool, but the FCC must be checked with the UEFI tool as the batteries do not show the health accurately in Windows.''***

If your laptop battery is older or reporting incorrectly, it may be possible to recalibrate the battery. This can correct the reported capacity or battery gauge to extend the life of the battery.

***''IMPORTANT: Recalibration only corrects the capacity on worn out batteries. There is no way to reverse the aging process.''***

For help understanding what calibration is, why it’s important, and how to calibrate batteries in other types of devices, check out the [[Battery Calibration|Battery Calibration Wiki.]]

=== ++Guide notes++ ===
* ***''If your battery exceeds 30-40 °C (86-104 °F), REPLACE THE BATTERY!''***
* ***''You will likely see a capacity decrease. This is good - not bad.''***
* ***''Try to avoid using the laptop while it is charging. This may affect the calibration.''***
* ***''Inconsistent reporting may indicate an EOL battery. Proper care delays this, but it cannot be avoided or reversed.''***
* ***''If your battery is older, consider a ~10% discharge. A full discharge may kill the battery.''***
=== ++How to recalibrate the battery++ ===
* Charge the laptop to 100%. Use it until it shuts down and no longer turns on.
** See ***''BIOS lockouts and EOL quirks''*** for HP and Lenovo laptops.
* Immediately recharge the battery. Do not use the laptop if possible.
=== ++BIOS lockouts and EOL quirks++ ===
* ***''(BIOS lockout) HP laptops have a 15% BIOS lockout and need to be bypassed for a full discharge.''*** Immediately charge the battery once the laptop shuts off.
** ***''All HP and most Compaq laptops.''***
* ***''(BIOS lockout)''*** Some Lenovo laptops have a 7% critical capacity lockout (0190).
** ***''Only occurs if the laptop shuts off early. Easily bypassed.''***
* ***''(EOL quirk) Some Dell batteries hold incorrect data once the battery is heavily worn, or end of life. This issue self corrects with time. I have seen this on a few OEM Dell batteries. Notably, the NX31D (DOM unknown/2x with same issue) 65Wh (2014 DOM/E6440) and a RMJFW 65Wh Extended (2014 DOM/E6220). The 45Wh 34GKR is prone to it, but to a lesser degree (2014 DOM/E7440).''***
* ***''(Firmware quirk) Some laptops will show 0% wear in BatteryInfoView - notably HP models. In order to access the data with HP, you must run the diagnostics (UEFI required if yours needs this). In some cases it can be found in the HP Support Assistant app by doing a battery check under the advanced info. This comes down to how HP encodes the battery data and how it is accessed and not a hardware fault.''***

***“++重要提示：++ ++虽然可以使用此方法校准HP笔记本电脑，但对于采用“UEFI”的HP笔记本电脑，这并不是推荐的方法++ - 如果可能的话，这些电脑应使用[link|https://support.hp.com/us-en/help/hp-pc-hardware-diagnostics|HP UEFI诊断工具]进行校准。此方法可替代HP工具使用，但由于电池在Windows中无法准确显示健康状况，因此必须使用UEFI工具检查FCC。”***

如果您的笔记本电脑电池较旧或报告不正确，则可以重新校准电池。 这可以纠正报告的容量或电池电量，以延长电池的使用寿命。

***''重要提示：重新校准只能修正磨损电池的容量。 没有办法逆转衰老过程。''***

如需帮助了解什么是校准、为什么它很重要以及如何校准其他类型设备中的电池，请查看 [[Battery Calibration|电池校准 Wiki]]

=== ++指南++ ===
* ***''如果电池温度超过 30-40 °C (86-104 °F)，请更换电池！''***
* ***''您可能会看到容量下降。 这很好 - 还不错。''***
* ***''尽量避免在充电时使用笔记本电脑。 这可能会影响校准。''***
* ***''不一致的报告可能表明电池已停产。 适当的护理可以延迟这种情况，但无法避免或逆转。''***
* ***''如果您的电池较旧，请考虑约 10% 的放电。 完全放电可能会损坏电池。''***
=== ++如何重新校准电池++ ===
* 将笔记本电脑充电至 100%。 使用它直到它关闭并且不再打开。
** 请参阅 HP 和 Lenovo 笔记本电脑的***“BIOS 锁定和 EOL 怪癖”***。
* 立即给电池充电。 如果可能，请勿使用笔记本电脑。
=== ++BIOS 锁定和 EOL 怪癖++ ===
* ***''（BIOS 锁定）HP 笔记本电脑有 15% BIOS 锁定，需要绕过才能完全放电。''*** 笔记本电脑关闭后立即为电池充电。
** ***“所有 HP 和大多数 Compaq 笔记本电脑。”***
* ***''（BIOS 锁定）''*** 某些 Lenovo 笔记本电脑具有 7% 的关键容量锁定 (0190)。
** ***''仅在笔记本电脑提前关闭时才会发生。 很容易被绕过。''***
* ***''（EOL 怪癖）某些戴尔电池一旦严重磨损或寿命终止，就会保存不正确的数据。 这个问题会随着时间的推移而自我纠正。 我在一些 OEM 戴尔电池上看到过这种情况。 值得注意的是，NX31D（DOM 未知/2x 有相同问题）65Wh (2014 DOM/E6440) 和 RMJFW 65Wh Extended (2014 DOM/E6220)。 45Wh 34GKR 很容易出现这种情况，但程度较轻 (2014 DOM/E7440)。''***
* ***“（固件怪癖）一些笔记本电脑（尤其是大多数HP型号）在BatteryInfoView中会显示0%磨损。若要通过HP访问数据，您必须运行诊断程序（如果您的电脑需要，则可能需要UEFI）。在某些情况下，可以通过HP Support Assistant应用进行电池检查，并在高级信息下查找相关数据。这并非硬件故障，而是HP的编码方式以及数据访问方式所导致的怪癖。”***
