Laptop doesn't sleep when battery is critical

[yoonghan]

Whenever my notebok reaches the critical level at 10%, it does not sleep like it is supposed to as done in the power settings. It immediately forces my notebook to power off, which is bad for the PC because everytime i reboot, it boots very slow unlike when shut down normally. I've changed different settings of the critical batter yand low battery, it still shuts off my laptop and not sleep/hibernate.

Thank you for joining HP Forums. 

This is a great place to get support, find answers to your technical queries.

I understand that notebook doesn't go to sleep mode when the battery is low,

To provide you with an accurate solution, I'll need a few more details:

Did it happen after a recent software update?

Have you tried to update the Bios?

Have you tried to run a test on the battery?

In the meantime, let's try these steps here: 

Perform a Hard reset on the notebook: 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

   If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

Next thing, I would suggest here is to check the settings under Control panel - 

Alternatively, I would suggest here is to update the Bios on your computer from our HP Support website, using this link.

1. Open the Control Panel.

   Press the Win+X keyboard shortcut and choose the Control Panel item from the supersecret menu.

2. Choose Hardware and Sound.

3. Choose Power Options.

   You see the laptop’s power plans. The battery warning levels are set for a specific plan.

4. Next, to the active power plan, click the link Change Plan Settings.

5. In the Edit Plan Settings window, click the Change Advanced Power Settings link.

   Finally, the Power Options dialog box shows up. It’s the happening place for all things having to do with power management in Windows.

6. Scroll the list, and locate the item labeled Battery.

   As you would expect, it’s the last item on the list.

7. Setting the warnings is only one part of good power management. Hopefully, you never see the low-battery notification and, most definitely, you never have the laptop automatically hibernate on you (for the critical-level action).

8. The low-battery warnings are independent of the Battery Saver setting.

9. When the low-battery notice sounds or appears and you’re blessed with a second battery for your laptop, pop it in and keep working!

10. That critical-battery notice is serious. Laptop time is over! You see no warning; the laptop simply hibernates or turns itself off — whichever option is set.

11. The best thing to do when power gets low: Plug in! This is why you might consider taking your power cord with you wherever you go.

12.  

13. Click the plus sign (+) by Battery to display various battery notification and action options.

    Each item has two subitems — one for settings when the laptop is on battery power and a second for when the laptop is plugged in.

14. Set the battery-level warnings.

    In chronological order, here are the items you can set:

    • Low-battery notification: Sets a warning for a low battery level, before the situation becomes critical. Values are set to On to set the low warning and Off to ignore it.

    • Low battery level: Determines the battery percentage for the low-battery-level warning. This value should be generous, well above the critical level.

    • Low battery action: Directs the laptop in what to do when the battery charge reaches the low-battery level. Other options are Sleep, Hibernate, and Shut Down.

    • Critical battery level: Sets the battery power level (percentage) for the crucial battery-level action.

    • Critical battery action: Directs the laptop to sleep, hibernate, or shut down when the critical battery level is reached.

15. Click OK to confirm the settings.

    You can close any remaining dialog boxes and windows.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

Once all the drivers are updated. 

Boot the computer to system diagnostics and run a battery test on your computer. 

To enter system diagnostics. Turn the computer On and keep tapping F2 repeatedly on startup. Click here for assistance. 

If the battery test fails, please replace the battery on your computer. 

Keep me posted, how it goes!
