HP x2 Detachable 10-p00XX mad battery state while charging

[DwarfDecker]

After a unwilled deep decharge,  bios show a menu telling that battery start is below normal limit.

Then after restart, % of charge show random value when charging ( that cause windows shutdown)

Everything looks OK when power adapter isn't plugged.

Laptop has allready be RMAed due to same issue.

It look like battery charge controller become made or calibrated ( leading to overflow in calculation)

I didn't find any way to fix issue, is there any hidden bios menu that allow to clear battery controller state ?

Bios diagnostic show battery data but said that battery is not installed while launching battery test !

It seems that when battery if physically charged enough ( > 50% ) issue disappear until next time discharge drop below 30%

Thank you for posting on the HP Support Community.

• Did this happen after a recent window or software update?
• Did you try another charger?
• Does the notebook shut down immediately (right after you unplug the charger)?
• Do you get any error message on your notebook (Such as Plugged in, not charging, etc.)?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

BIOS default: 

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. If the issue persists, follow next steps.

Run hardware diagnostics test on battery and Charger:

Use the following steps to open the Component Tests menu.

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3. On the main menu, click Component Tests.
4. The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.
5. To run both tests simultaneously, in the Component Tests menu, click Power Source, and then click Run once. Each component can also be tested individually.

AC Adapter Test:

The AC Adapter test provides an interactive test to determine if the AC power adapter is functioning properly. A good battery is required for this test. Before running the AC Adapter Test, HP recommends verifying that your computer can receive power by connecting a known working AC adapter.

Follow these steps to perform the AC Adapter Test.

• In the Component Tests menu, click Power, and then click an AC Adapter Test.
• Click Run once.
• The AC Adapter Test begins.
• When the test is complete, the results are displayed on the screen.

Battery Test:

Follow these steps to perform the Battery Test:

1. In the Component Tests menu, click Power, and then click Battery.
2. Click Run once. The Battery Test begins.
3. When the battery test is complete, the results are displayed on the screen. For additional battery information, click Battery Details.

If the test passes, continue with these steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.

• If possible, try an alternate charger.

Hope this helps! Keep me posted for further assistance.

Background : I had the same issue once, laptop sent to repair shop  ( MB et Battery where replaced), it worked fine until first full discharge --> Strange bios menu shown at boot time telling that discharge state was too low ( char menu with dark background , not like usual bios screens)

Thing done:

* Bios update to 34F rev A --> No improvement

* Charger works fine , power test pass, battery charge time is Ok

* Manual calibrate cycle has been done --> No improvement

* Wear level check , less than 4% loss

Behavior:

* When unpluged charge state is OK

* When plugged and battery charged over 50% , charge state is OK

* When battery  charged  0 - 50 % and plugged:

   - Charge %  take random value ( look like computation overflow --> SW bug)

   - Voltage, current capacity and other value are randomly abnormal ( 42V voltage, 800% capacity, wearlevel > 100%....) --> Value goes back to normal values when power supply is unplugged

Assumption:

* Battery controller get carzy after a full discharge ( may be due to draw mAh exceeding current capacity --> lead to negative computation not managed by firmware ( I'm a embedded software engineer)

[DwarfDecker]

 I forgot to tel that bios hardware monitoring ( F2 menu):

* Report Battery OK when unplugged

* Battery Not installed ( charge state  = 0xFF ) when charge state is below 50% and power is plugged

* Battery OK when charge state is over 50% and power is plugged

Same outcome with HW battery check application for windows

Note: On HP X2 battery is not removable ( unless housing had been opened and I guess a connector has to be unplugged from mother board )
