Your Chromebook is plugged in, but the battery percentage isn't moving. A rising percentage is the clearest confirmation that it's actually gaining charge. Start with the on-screen status, then check the charging light, charging settings, or built-in Diagnostics to explain what you're seeing.
Check the battery status on your screen
Connect your charger to the Chromebook and a working outlet.
Select the battery/time area at the bottom right to see the battery level and estimated time until fully charged.
For keyboard access, press Shift + Alt + S to open the same status area.
Read the battery percentage. Don't rely on the time-to-full estimate alone: it isn't always available during calculation or a charging pause.
Check the percentage again later. An increase confirms that the battery is gaining charge. A power connection alone doesn't establish that.
Tip: The yellow “+” battery symbol means Battery Saver is on, not that your Chromebook is charging.
Make sense of the charging light
Charging-light confusion comes from using one model's color chart to read another model's indicator.
Look for your Chromebook's charging light, usually near a charging port. On models with an indicator, you can check it even when the screen is off.
Match the light to your exact model's manual. An unlit indicator doesn't automatically mean charging has failed.
On Samsung Chromebooks that use the following Power LED pattern, red means charging, green means fully charged, and blue means powered on. Blinking red means no battery or pre-charging, not completed charging. Check your model's manual for exceptions.
On the Pixelbook Go, solid orange means charging, solid white means fully charged, and blinking red means low charge.
The ASUS CX5601FBA and CB5601FBA use solid orange for connected power and charging below 95%. Solid white means connected power with 95–100% charge. Blinking orange means battery operation below 10%, while an unlit indicator means battery operation at 10–100%. Those thresholds apply specifically to these two models.
For the Dell Chromebook 11 CC11260, solid white with the adapter connected means charging, while an unlit indicator means fully charged. Solid amber means a low or critical battery. Use this chart only for that model.
Find out why the percentage stays around 80%
A battery sitting around 80% doesn't automatically signal a problem. On supported Chromebooks, Adaptive charging holds the battery around 80% when delaying a full charge, while Charge limit caps it at 80%.
Select the time to open the status area.
Open Settings.
Select System preferences.
Open Power.
Select Change under Optimized charging to inspect Adaptive charging or Charge limit. Availability depends on your Chromebook and administrator policy.
Select Fully charge now in the Adaptive charging notification to resume charging toward full. This notification action belongs to Adaptive charging; it isn't a general override for the separate Charge limit mode.
If these settings don't explain the unchanged percentage, open Diagnostics using the steps below to inspect the battery more closely.
Use Diagnostics for a closer look
The built-in Diagnostics app gives you more battery information without a download.
- 1.Keep the charger connected to the Chromebook.
- 2.Press the Launcher key, type Diagnostics, and open Diagnostics.
- 3.Inspect Battery for electrical current, battery health, and cycle count. Battery health describes capacity condition, not whether the battery is charging right now.
- 4.On Lenovo ideapad and ThinkPad Chromebooks that offer the charge test, select Run Charge test with the battery below 95%. Let the test finish, then review its result. Test availability and label capitalization vary by ChromeOS build.
- 5.Check the battery/time area again later for a rising percentage. Use that increase or the charge-test result to assess charging activity separately from battery health.
Give a depleted Chromebook time to charge
If the screen stays black and the battery is depleted, leave the Chromebook connected to power for at least 30 minutes before reassessing it. That's Google's recommended waiting period.
Connect the charger to the Chromebook and a working outlet.
Leave it connected for at least 30 minutes.
Check the charging light after that wait. Interpret it using your model's manual, including whether an unlit indicator means the battery is full.
Once the screen is available, open the battery/time area.
Check the percentage again later. A rising percentage confirms actual charge accumulation more clearly than a power light alone.
Frequently Asked Questions
Does a charging sound prove my Chromebook is charging?
The sound confirms a power-connection event, not continued battery charging. On Chromebooks with the setting, open Settings > Device > Audio. Under Device sounds, enable Charging sounds, then connect the powered charger to hear the connection sound.
Can I hear my Chromebook's battery level?
Yes. Press Ctrl + Alt + Z to enable ChromeVox. Then use Search + O + B or Launcher + O + B to hear remaining battery information. On tablets, hold Volume down + Volume up for five seconds to enable ChromeVox.
Why are charging settings unavailable on my school or work Chromebook?
Administrator policies control access to charging options and charging sounds on managed devices. Ask your administrator to inspect Battery charging optimization or Charging Sounds under Google Admin console > Devices > Chrome > Settings > Device settings for your device's organizational unit.
Does “charging or full” in Crosh mean the battery is gaining charge?
No. That combined result doesn't distinguish active charging from a full battery. Compare successive battery percentages or inspect Diagnostics to determine whether the battery is gaining charge.
