Checking Battery Health Status on Dell Laptops and Notebooks

Checking Battery Health Status on Dell Laptops and Notebooks

The article below will help you check the current health status of your system battery. This can be done both outside and inside the operating system environment. Also discussed will be the diagnostic indicators if your system has any available and how to test the battery using the Dell diagnostics.

Note: Like most laptops, Dell laptops use lithium ion batteries, which can swell for a variety of reasons such as age, number of charge cycles, or exposure to high heat. While a swollen pack does not represent a safety concern, damaged or swollen components should not be used. Should you have an issue with a battery pack swelling, we recommend discontinuing use and replacing it with a Dell authorized battery.
Note: Battery life may decline over time - this is considered a normal characteristic of a rechargeable battery and not a fault covered by warranty.
Note: If the battery health is blank or grayed out then there could be an issue with the battery not being detected properly or a fatal error with the battery. Where possible in this instance try swapping in a known good battery from a same specification system or re-seat the battery in it's compartment.
  1. Tap the < F2 > key at the Dell Logo to enter system setup. (BIOS) (Figure 1)

Battery Info

    • Battery charge level - Blue
    • Battery Health Status - Red
    • AC Adapter - Green

Alternatively check the battery health within Windows:

  1. Start > Control Panel > Hardware and Sound > Power Options > Dell Battery Meter

  2. Or open Mobility Center and check the battery status: (choose one of the 3 steps below to access)

    1. Press < Windows > + < X >
    2. Open control panel and click on Windows Mobility Center.
    3. Press the < Windows > + < R > keys to open the Run dialog, type mblctr.exe, press < Enter >

Check Battery Charge LED Status:

Battery LED

If the laptop is connected to an electrical outlet, the power/battery light operates as follows:

Power State Charging status LED Behavior
On Any (0-100%) Solid white
Standby Any (0-100%) Breathe white (slow increase/decrease in illumination)
Off, hibernate >90% charge Off
Off, hibernate =90% charge Solid white

If the laptop is running on a battery, the power/battery light operates as follows:

Power State Remaining battery power LED Behavior
On =10% charge Solid white
On <10% charge Solid amber
Standby =10% charge Breathe white (slow increase/decrease in illumination)
Standby <10% charge Solid amber
Off, hibernate Any (0-100%) Off
Note: Please be aware older versions of the diagnostics may not test the Battery. This was only introduces in the Enhanced PSA Diagnostics. (example Latitude E3 systems onwards E5420,E6220,E6420 ...)

Try running the ePSA diagnostics on the system, the range of tests includes the Primary Battery.

This tests only the primary battery in a system. The battery is tested by displaying its percentage of full charge and its overall health.

To start diagnostics:

  • Hold down the < Fn > function key and power on the notebook
  • Alternatively tap the < F12 > key at the Dell logo to boot to the one time boot menu and select Diagnostics from the menu.
Error Number Error Message Action to be Taken

ePSA: Battery -The battery is reaching the end of its usable life

Troubleshoot the battery further, this message only advises on the natural degradation of the batteries full capacity performance.

Run the battery diagnostics

To run the test, browse to the Dell Battery Diagnostics.

Note: You may need to provide your service tag or select your computer model from a list.
  1. Click Battery Life.

  2. Click Run Diagnostics.

  3. Troubleshoot the battery further with article Dell Notebook PC: Battery Troubleshooting Guide.

To run a full diagnostic on your computer, go to the Dell PC Diagnostics page, click the Advanced tab and click Run Diagnostic.

See article How to improve your laptop battery's performance

ePSA 2000-0133

ePSA: Battery - The battery cannot provide sufficient power
  1. Check contacts, power plug and cables.
  2. Reseat the battery.
  3. To troubleshoot further see article Dell Notebook PC: Battery Troubleshooting Guide.
  4. If the issue remains you may need to replace battery.
Note: If your error code is different than those listed above, you can log a service call using the following link, Enhanced Preboot System Assessment. You will need to enter the Error and Validation code as seen on the screen, you will also need to enter the Service tag of the faulty computer, just follow the prompts to complete the process.

The charge state of the battery pack is monitored and stored within registers internal to the battery pack electronics. This may be referred to as a fuel gauge. The charge status LEDs on the battery pack indicate the remaining charge in the following manner:

Note: Not all Dell™ portable system models have the LED bar graph on the battery pack. Check the system documentation for availability.

  • - 81% - 100% charge capacity remaining
  • - 61% - 80% charge capacity remaining
  • - 41% - 60% charge capacity remaining
  • - 21% - 40% charge capacity remaining
  • - 5% - 20% charge capacity remaining
  • - 0% - 4% charge capacity remaining
  • - The battery pack has failed or is damaged. For more thorough failure description, refer to third step in this document: System Battery/Charge LED.

Battery degradation status indication.

Portable system batteries as with all other rechargeable batteries degrade over time. The amount of time the battery will operate the device on a full charge will reduce as the battery ages. This performance loss is also based on the number of times the battery is discharged and charged. Dell portable system batteries provide a way to monitor the degradation. The degradation status will display after holding the battery check button, located on the battery pack, down for more than 3 seconds. The battery pack LEDs will then show overall battery degradation after the charge gauge reports the battery's current charge capacity. The degradation LEDs display the following:

  • - 100% - 80% charge performance is remaining
  • - 79 - 75% charge performance is remaining
  • - 74 - 70% charge performance is remaining
  • - 69 - 65% charge performance is remaining
  • - 64 - 60% charge performance is remaining
  • - 59% or less charge performance is remaining

System Battery/Charge LED

The hinge or system battery LED can indicate many battery states. The LED can blink and change color representing the battery's current operational condition. The LED indicates the following states (click the image for a larger view in a new window):

  • - Temporary Battery Failure

  • - Fatal Battery Failure

  • - Unsupported (non-Dell) Battery

  • - Battery Below Low Battery 2 Threshold

  • - Battery Below Low Battery 1 Threshold

  • - Battery Being Charged

  • - Battery in Trickle Charge Mode
