Common ASUS Laptop Charging Problems and Their Causes
ASUS laptops can experience several types of charging issues. Understanding what type of problem you’re facing helps you find the right solution faster.
ASUS laptop not charging when plugged in is the most common issue users report. This happens when your laptop shows no signs of charging even with the charger connected. The battery percentage doesn’t increase, and there might be no charging indicator light.
ASUS laptop not recognizing charger occurs when your laptop doesn’t detect that a charger is connected at all. You might see error messages or the battery icon shows it’s running on battery power even with the charger plugged in.
Battery not charging to full capacity is another frequent ASUS laptop charging problem. Your laptop might charge to 60%, 80%, or 90% and then stop, even though it should reach 100%.
Charger working but not charging battery means your laptop powers on when plugged in, but the battery itself isn’t charging. This suggests the charger is providing power but not charging the battery.
USB-C charging issues affect newer ASUS laptops that use USB-C ports for charging. Problems include slow charging, intermittent charging, or no charging at all through USB-C ports.
Why is My ASUS Laptop Not Charging?
Understanding why your ASUS laptop isn’t charging helps you choose the right fix. Here are the most common causes:
Physical connection problems are the simplest but most frequent cause. Check for loose connections where the charger plugs into your laptop. A damaged charging port, frayed cable, or bent pins can prevent proper charging. Even a slightly loose connection can cause ASUS laptop charger problems.
Software and driver issues often cause charging problems. Outdated or corrupted battery drivers, power management software conflicts, or Windows updates can interfere with charging. This is especially common after system updates.
Battery health settings in MyASUS software can prevent charging. ASUS laptops include Battery Care Mode or Battery Health Charging features that limit charging to 60% or 80% to extend battery life. If you’ve enabled these settings, your laptop might stop charging at the set limit.
Power management conflicts occur when the system gets confused about power states. This can happen after sleep mode, sudden shutdowns, or when switching between power sources. The laptop might think it’s charging when it’s not, or vice versa.
Hardware failures are less common but more serious. These include a dead battery, failed charging circuit, damaged motherboard components, or a faulty charger. Hardware issues usually require professional repair or replacement.

Frequently Asked Questions
Why is my ASUS laptop not charging even though it’s plugged in?
Your ASUS laptop might not be charging even when plugged in due to several reasons. The most common causes include a loose connection between the charger and laptop, a damaged charging cable, or a faulty power outlet. Software issues like outdated drivers or corrupted power management systems can also prevent charging. Sometimes, the battery itself might be dead or the charging port could be damaged. Start by checking all connections, trying a different outlet, and inspecting the cable for damage. If these basic checks don’t work, try performing an EC reset by holding the power button for 60 seconds with the charger unplugged and battery removed (if possible).
How do I know if my ASUS charger is broken or if it’s the laptop?
To determine if your ASUS charger is broken or if it’s the laptop, try these tests. First, inspect the charger for visible damage like frayed wires or bent prongs. If possible, test your charger with another compatible ASUS laptop. If the charger works on another laptop, the problem is with your laptop. If you have access to another known-working ASUS charger, test it with your laptop. If your laptop charges with the different charger, your original charger is faulty. You can also check if your laptop powers on with the charger plugged in – if it does but the battery doesn’t charge, the issue might be with the battery rather than the charger.
Can a bad battery cause an ASUS laptop to not charge?
Yes, a bad battery can definitely cause your ASUS laptop to not charge properly. When a battery fails completely or develops internal faults, it can prevent the charging system from working correctly. Sometimes the laptop will show “plugged in, not charging” or won’t recognize the charger at all. A swollen or bulging battery is a clear sign of failure and should be replaced immediately. Even if the battery isn’t completely dead, a severely degraded battery might not accept a charge. If you’ve tried all software solutions and different chargers without success, the battery is likely the culprit and needs replacement.
Why does my ASUS laptop say “plugged in, not charging”?
The “plugged in, not charging” message on your ASUS laptop usually indicates one of three issues. First, you might have Battery Care Mode enabled in MyASUS, which limits charging to 60% or 80% to extend battery life. Check your MyASUS settings to see if this is the case. Second, the battery might be fully charged already – some ASUS laptops stop charging at 95-100% to protect battery health. Third, there could be a communication problem between the charger and battery, often caused by outdated drivers or a faulty charging system. Try updating your drivers, performing an EC reset, or checking your battery health settings.
How long do ASUS laptop batteries typically last?
ASUS laptop batteries typically last 2-5 years or 300-500 charge cycles, depending on usage patterns and care. A charge cycle is one full discharge and recharge. Most users experience noticeable battery degradation after 2-3 years of regular use. Gaming laptops and high-performance models tend to have shorter battery lifespans due to higher power consumption. Factors that affect battery life include charging habits (frequent deep discharges shorten battery life), temperature exposure (heat damages batteries), and whether you use Battery Care Mode. With proper care, including using the 80% charge limit and avoiding extreme temperatures, you can extend your ASUS battery’s life to 4-5 years.
Is it safe to use a third-party charger with my ASUS laptop?
Using a third-party charger with your ASUS laptop can be safe if you choose carefully, but it comes with risks. Look for chargers that match your original ASUS charger’s exact voltage (V) and wattage (W) specifications. The charger should have proper safety certifications like UL, CE, or FCC. Avoid very cheap chargers as they often lack proper safety features and can damage your laptop or even cause fires. Using a non-ASUS charger may also void your warranty. For safety and compatibility, genuine ASUS chargers are always the best choice. If you must use a third-party charger, buy from reputable brands and retailers, never from unknown online sellers.
Why is my ASUS laptop charging slowly?
Slow charging on your ASUS laptop can be caused by several factors. Using a lower-wattage charger than what your laptop requires is a common cause – check your original charger’s wattage and ensure you’re using one with equal or higher power. Running demanding applications or games while charging can also slow down the charging process. USB-C charging might be slower if you’re using a port that doesn’t support power delivery. Background processes, outdated drivers, or a failing battery can also contribute to slow charging. Try closing unnecessary applications, using the original ASUS charger, updating your drivers, and checking your battery health. If the problem persists, your battery might need replacement.
Conclusion
ASUS laptop charger problems can be frustrating, but most issues are fixable with the right approach. Start with basic checks like inspecting cables and trying different outlets, then move to software solutions like updating drivers and performing an EC reset.
