To fix a Lenovo Chromebook that won't turn on, reconnect its charger, charge for at least 30 minutes, then try a hardware reset if it still will not start. Before resetting, check whether it is asleep or running with a dark screen. Save ChromeOS recovery for a device that can display its recovery screen, because recovery erases local data.
The short version
- Start with charging: Secure both charger connections, check the outlet, and charge for at least 30 minutes.
- Check the display: Try waking the Chromebook and increasing screen brightness before treating a dark screen as a power failure.
- Reset the hardware: On most Chromebook laptops, turn it off, hold Refresh, tap Power, and release Refresh when startup begins.
- Protect local files: A hardware reset can remove some Downloads files, while Powerwash and recovery erase local user data.
- Know when to stop: Contact Lenovo if charging and hardware resets fail, especially when no recovery screen appears.

Check the charger and allow time to charge
Check that the charger is secure at both the Chromebook and the wall, and confirm that the outlet works. Unplug the charger from both ends, reconnect it to the Chromebook first, then connect it to the wall. Leave it charging for at least 30 minutes before pressing Power again.
Look for a charging indicator while it is connected. Use your exact model's manual to identify the charging connector and interpret its lights, since both vary by Lenovo model. Another Lenovo Chromebook's light colors may not apply to yours.
Use the original AC adapter or a Lenovo option adapter approved for your exact machine. Lenovo specifically recommends this when a Chromebook stops powering on and its charging light stays off after using a third-party charging cart. If a correct replacement adapter restores charging, allow at least 30 minutes before trying startup again.
Check for sleep or a blank display
Open the lid and swipe the touchpad to wake a sleeping Chromebook laptop. On a Chromebook tablet, press Power. If the device was shut down, connect it to power and press its physical Power button, using your model's manual to locate it if needed.
A dark screen can make a powered Chromebook look completely off. On models with a brightness key, press Brightness up to increase the built-in screen brightness. If the device has power but the screen stays dark, focus on checks for a laptop with power but no display.
If your Lenovo Chromebook supports external video output, connect a compatible monitor or TV using the supported connector and adapter. If you can access ChromeOS, select the time, then open Settings > Device > Displays and select Mirror Built-in Display. An external display can help identify a built-in screen problem, but it cannot restore absent electrical power.
Restart an unresponsive Chromebook
To restart a computer that is unresponsive, Lenovo's 500e Chromebook Gen 4s instructions say to hold Power until it turns off. Release the button, then press Power to start it again. Check your model's manual if its restart procedure differs.
When the screen and interface still respond, select the time, select Power, then choose Restart. You can also choose Shut down from that menu and start the Chromebook again with Power. If restarting does not help, move to the hardware reset.
Use the correct hardware reset
Google warns that a hardware reset can remove some files in Downloads, so back up accessible local files before proceeding. For most Lenovo Chromebook laptops with a ChromeOS keyboard, turn the Chromebook off, hold Refresh, and tap Power. Release Refresh when startup begins.
If the standard procedure does not help, Google also documents an alternative for Chromebooks with the corresponding keys. Hold Back + Refresh + Power for at least 10 seconds.
On Lenovo Chromebook tablets and detachable models using Google's tablet procedure, hold Volume Up + Power for at least 10 seconds, then release both. This two-button reset differs from the three-button combination used to enter tablet recovery mode. If the screen remains dark, check your model's specific reset instructions next.
Check model specific power reset instructions
Lenovo gives an additional procedure in its 500e Chromebook Gen 4s guidance for an unresponsive system with a built-in battery and no emergency-reset hole. Disconnect all power sources, hold Power for about seven seconds, then reconnect AC power and restart. Check your exact model's manual before applying that timing to another Lenovo Chromebook.
Use a paper clip only when your exact model's manual identifies an emergency-reset hole. For models with that documented feature, insert a straightened paper clip into the identified hole to interrupt power temporarily, then restart with AC power connected. Do not insert it into an unidentified opening.
Use Powerwash or recovery when the screen works
Choose the next step based on how far the Chromebook starts. The Powerwash shortcut requires access to the sign-in screen, while recovery requires working recovery firmware and a visible recovery screen. Both erase local user data, so back up accessible files first. For a work or school Chromebook, contact your administrator before resetting or recovering it.
If your personal Chromebook reaches the sign-in screen but startup problems continue, you can factory reset your laptop using Powerwash. Sign out, hold Ctrl + Alt + Shift + R, then select Restart. Select Powerwash, choose Continue, and complete setup and sign in after the reset.
When ChromeOS will not start, remove connected accessories, including a mouse and external hard drive, before entering recovery. On a Chromebook laptop, hold Esc + Refresh, press and release Power, then release the remaining keys when a message appears. Some models use Esc + Maximize instead; confirm the combination for your model.
On a Chromebook tablet, hold Volume Up + Volume Down + Power for at least 10 seconds, then release them. On newer models that display Recover using internet connection, select it, connect to the network as prompted, and complete recovery. If that option is absent, use external recovery media.
To create recovery media, use another working Chromebook, Windows PC, or Mac. On a supported Windows PC or Mac, install Google Chrome if needed, then install Google's Device Recovery Utility. Google also calls this tool Chromebook Recovery Utility in its recovery instructions.
Open the utility in Chrome, select Get started, identify the affected Chromebook's model, and select Continue. Insert a USB drive of at least 8 GB whose contents you can erase, select that drive, then choose Continue > Create now. Creating the recovery media erases the USB drive and requires an available recovery image for your Chromebook.
On the affected Chromebook's recovery screen, select Recover using external disk and follow the prompts with the prepared USB drive. Recovery reinstalls ChromeOS and erases the Chromebook's local data. If you cannot get a recovery screen after charging and hardware resets, contact Lenovo support.
Check updates and battery health after startup
Once the Chromebook starts, connect it to Wi-Fi and power. On a model still eligible for ChromeOS updates, select the time and open Settings > About ChromeOS > Check for updates. Allow the download to finish, then select Restart in the Update device notification. If your Chromebook is managed by work or school, you may need your administrator's help.
On ChromeOS 90 or later, select the time and open Settings > About ChromeOS > Diagnostics to inspect battery health, cycle count, and electrical current. Use the battery discharge test to investigate battery behavior. CPU and memory tests can also help if the apparent power problem turns out to be recurring freezes.
For a Chromebook that starts but keeps freezing, continue with steps to fix a frozen laptop. If the trouble began after installing an extension, open Chrome's More menu, then select Extensions > Manage extensions. Turn off suspect extensions individually and check whether the freezes return. Managed extensions may require your administrator's help.
Contact Lenovo when power still does not return
Arrange Lenovo diagnosis or repair if charging and hardware-reset attempts fail, particularly when there is no charging response or recovery screen. Have your model, serial number, charging-light behavior, and any blinking pattern ready. Explain which charger and reset procedures you already tried so support can continue from those results.
Frequently Asked Questions
Why will a stored Lenovo Chromebook not wake when the lid opens?
If your Chromebook was placed in battery-disconnect storage mode, connect its charger to the Chromebook and a power source, then press Power. Opening the lid or pressing Power alone cannot wake that state.
What do the charging light colors mean on a Lenovo 500e Chromebook Gen 4s?
On your Lenovo 500e Chromebook Gen 4s, red means charging below 5%, amber means 5% to 97%, and green means 97% to 100%. For another Lenovo Chromebook, use its exact model manual because indicator behavior varies.
Can Safety Reset help without deleting local files?
Safety Reset disables extensions and resets relevant settings while retaining your local files and apps. If your Chromebook starts and offers the option, select the time, open Settings > System preferences, and under Reset, select Safety reset. Select Done when it finishes. Your administrator may restrict access on a managed Chromebook.
How can you stop sleep from looking like another power failure?
After startup is restored, select the time and open Settings > System preferences > Power. For While inactive and plugged in and While inactive and on battery, select Keep display on. You can also turn off Sleep when lid is closed if that behavior suits your needs. Your administrator may restrict these settings on a managed Chromebook.
