Asus Chromebook CX1500CKA-AS84F Does Not Power On

If your Asus Chromebook CX1500CKA-AS84F doesn't turn on when the power button is pressed, follow this page for solutions.

If the power adapter is damaged or not providing enough power, the Chromebook won’t turn on.

If you’re using the original Asus USB-C charger, check that both ends of the adapter are securely seated and that the outlet is functioning.

1. When the charger is plugged in, the indicator light on the side of the Chromebook should illuminate (orange when charging, green/white when fully charged).
2. Try plugging the charger into a different outlet or using another compatible charger if available.
3. If the Chromebook still does not show any charging indicator, the problem may be with the adapter, battery, or charging circuit.
4. If available, test with another compatible charger. If the Chromebook powers on with a different charger, replace the original adapter.

A discharged or failing battery can prevent the Chromebook from powering on.

1. Leave the charger connected for at least 15–30 minutes before attempting to power on.
2. If the Chromebook only works when plugged in but shuts off immediately when unplugged, the internal battery is likely failing and needs replacement.
3. Inspect the battery if possible: if it looks swollen or misshapen, replace it immediately.

3. If the system still does not boot, you may need to perform a ChromeOS recovery using a USB drive.

If the power adapter, battery, and display are all functional, but the Chromebook still won’t power on, the problem may lie with the motherboard. The motherboard can be damaged by power surges, liquid spills, overheating, or physical impact. When this happens, the Chromebook may not power on at all.
