ASUS's charging article for notebooks and gaming handhelds gives the order: check the adapter and power cord (use the original ASUS adapter and cable and do not mix adapters between different ASUS products, because output specifications differ), check the jack for looseness at the cord, outlet and device ends, try different outlets, inspect for damage and, if the machine has not been charged for a while, leave it charging overnight. If USB Type-C charging is used, the port must support battery charging. Then it says to try an EC reset, RTC reset or hard reset, update the BIOS, Windows packages and drivers, and restore BIOS settings (F2, or Volume down plus power on a handheld).
The ROG Ally X charges over USB-C, so a phone charger may not deliver enough for it.

Before you touch a setting
Record this first — changing settings destroys the evidence
- Which ASUS machine you have and the adapter's printed wattage and connector
- Whether you charge by the barrel or USB-C connector and what the charging light shows
- What Windows and MyASUS report about the battery

Check the connections
ReversibleCheck the connections, by checking the jack at the cord, outlet and device ends, and trying a different outlet.
Charge overnight
ReversibleCharge overnight, and if the battery has been unused, leave it connected overnight, as ASUS says.
EC, RTC or hard reset
ReversibleFollow ASUS's reset article; the long power-button press is 40 seconds for the EC reset.
Restore BIOS defaults
ReversibleHold F2 and press power (Volume down and power on a handheld), restore defaults and save.
Book service
ReversibleBook service, and if it still will not charge, contact an ASUS service center for the laptop.
Model-specific
What is true of this model and not of its siblings
- Charging by model
- ASUS's articles apply to notebooks and gaming handhelds. The Ally X charges by USB-C; thin laptops commonly charge by USB-C or a barrel connector depending on model. Read the adapter's label.
- Resets
- EC reset: long-press the power button for 40 seconds. RTC reset and hard reset are covered in ASUS's reset article.
- Repair cost
- The charger and cable are the cheap suspects. A charging-port repair at an independent shop is $129 to $179 and a battery replacement $129 to $249, per BadgerLayer's 2026 laptop repair guide.
- Other models this page answers
- These steps also fit the ProArt P16 H7606, ROG Zephyrus G14 GA403, Vivobook S 15 S5507, ROG Ally X handheld.
Stop boundary
When this stops being a self-service repair
- !If the machine charges on another original adapter, replace the failed adapter
- !If it will not charge on a known-good original adapter after the EC reset and BIOS steps, contact an ASUS service center
- !If the case swells or the battery is very hot, stop charging and go to a service center the same day

Exact questions
Common questions
Does a warm charger mean it is faulty?+
A charger that is warm to the touch under load is normal. One that is too hot to hold, smells of burning or buzzes loudly should be unplugged and replaced.
How do I read the charger's rating?+
The label on the adapter lists volts and amps or watts. Compare it with the number printed on the laptop's rating label; a lower-wattage charger may power the laptop but charge slowly or not at all under load.
Can I use a different ASUS charger?+
ASUS says to use the original adapter and cord and not to mix adapters between different ASUS products because power output specifications may differ.
Does every USB-C port charge?+
No. ASUS says a Type-C port must support battery charging; check the user manual for your model.
What if it has been in a drawer for months?+
ASUS says connect it to power and leave it charging overnight; this may help revive the battery.
What is an RTC reset?+
A reset of the real-time clock that ASUS lists alongside the EC reset and hard reset to restore hardware to defaults.
Does the ROG Ally X charge differently?+
It charges by USB-C; ASUS's article notes handhelds enter BIOS with Volume down plus power. Use its own adapter for full speed.
Why does the machine run on battery while plugged in?+
ASUS has a separate article on slow charging and draining while plugged in; a low-wattage adapter under heavy load is the usual cause.
