You might be frustrated because your Asus laptop is not responding after pressing the power button multiple times. In some cases, the screen went completely black, while in other cases, the ASUS logo showed but failed to boot.
The main causes include Asus laptop battery/adapter, RAM, graphics card, CPU and even motherboard failure. Technically, you could be experiencing any of four issues: no power, no POST, no boot, or no video.
Each has a different meaning and requires individual troubleshooting to resolve. Since your Asus laptop won’t turn on at all, I’ll try to highlight the “no power and no POST” scenario.
Check the power light and beep codesFirst, I recommend checking the power LED to see if your laptop is experiencing no power issues.
As shown in the picture above, Asus laptops come with two to four indicator lights. In this article, I will only focus on the power (identified by the light bulb symbol) and Asus laptop battery indicators. They may be located next to the I/O panel (on the right) or within a separate light panel (on the bottom front). If the power light doesn’t light up any lights, know that your laptop isn’t receiving any power. This usually indicates that the Asus laptop battery is drained (no charge left) and your device is seeking power from an external source.
While plugging in a power cord usually solves the problem, it can also mean your Asus laptop won’t charge at all. To confirm this, check theAsus laptop battery indicator light. If charging, it will illuminate solid orange (if less than 95%) or green (more than 95%).
However, if you notice the orange light blinking (even when the power adapter is plugged in), that means your Asus laptop is running on Asus laptop battery. But its charge is less than 10% (in this case, probably 0).
This may be caused by a faulty power port, charger, battery, or electrical outlet. Check each part thoroughly to make sure they don’t have any damage. Check for bent/broken power cords, frayed cables, swollen or leaking batteries, and that the wall outlet is functioning properly.
If you have spare power adapters or batteries (original power adapters or batteries only), install them to find out if the old one is indeed damaged. Additionally, you can try charging your laptop on another wall outlet to find out if there is a power issue with the previous outlet.
If your laptop won’t turn on and you hear beeps during startup, this is a POST failure and usually indicates a hardware issue.
To find out which component is preventing your Asus laptop from booting, follow our other article discussing Asus beep codes (for desktops and laptops).
Let ASUS laptop complete memory trainingSometimes, your Asus laptop won’t turn on (but the power light comes on) after replacing the memory module or Asus laptop battery. This has also been reported to happen to some users who cleared their CMOS.
If you encounter a similar situation, connect the charger and start the laptop. Then, wait about 1 to 3 minutes until the memory training process is completed. Do not force shut down the system and plug in the power cord during this process.
The process varies based on the size of RAM. During the boot process, the ASUS motherboard initializes all installed memory, tests them, and organizes them in a pool. After waiting a few minutes, the system should boot, fixing possible startup glitches.
Perform an EC/hard resetIf you wait more than 3 to 5 minutes and still no signs are showing, I recommend you to hard reset your Asus laptop. This involves resetting the embedded controller (EC), the microcontroller responsible for power management functions Additionally, this will clear the CMOS in newer models.
Doing so will reset the hardware components to factory default settings. Therefore, it may solve fundamental problems with laptop battery, power, charging, and other hardware components.
First, completely shut down your Asus laptop (if the power LED is on). To do this, you need to press and hold the power button for 15 seconds (until the power LED turns off).Press the power button to discharge the capacitor. Now disconnect all peripherals to avoid possible interference. This includes all input/output devices as well as external storage drives.USB ports and connectors
Next, unplug the power adapter from the dedicated power port on your Asus laptop.Remove the power adapter from the laptopBut if you’re using the TP420IA or UX425IA models, keep them plugged in. Both models require a power connection to perform a hard reset.
Also, I recommend removing the external battery from the Asus laptop battery compartment (if your Asus laptop has one).
How to remove a laptop batteryIf you installed new memory modules or hard drives, you will also need to remove them.Remove the memory stick from the laptopFollow the manufacturer’s recommendations by pressing and holding the power button for at least 40 secondscondition. This should reset the embedded controller and the hardware should return to its default state.
Press the power button to discharge the capacitorFinally, reconnect the removed memory module and charger and boot the device.Check LCD an laptop battery cables for faultsIf you have previously disconnected the LCD cable or made changes to the display panel, this may cause a no display issue. Apart from this, a disconnected laptop battery cable can also cause this issue.
Before you begin: Since you’ll be working with the internal parts of your Asus laptop, I highly recommend grounding yourself to keep excess charges away from you and the components. Not only does this protect you from electrical shock, it also prevents delicate components from being affected by ESD.
First shut down your Asus laptop properly.Also, remove all external connected devices such as keyboard, mouse, SD card, hard drive, etc.Now, close the lid and turn over your Asus laptop.If you have an older Asus model, it may have an external Asus laptop battery. Therefore, you need to delete it as well.
Use a screwdriver with the appropriate drill bit size to remove each screw holding the bottom housing in place. Make sure to keep them somewhere safe (magnetic trays or mats are best).Laptop case unscrewed
Next, use a plastic pry tool to pry out the case (as much as possible). Alternatively, you can even use iFixit Jimmy, as shown below. Use extreme caution when performing this procedure.Pry tool to pry off the bottom caseNow, find the internal laptop battery (not available if you have an external battery) and the dedicated cable that connects it to the
motherboard.If the cable is loose or removed, simply tighten it to power up the laptop.If this doesn’t help, completely disconnect the batterycable.Twist to disconnect the internal Asus laptop battery connectorThen, use a plastic spudger or use two fingers to gently shake the LCD cable to disconnect it.Reconnect the LCD cable
Clean both connectors (LCD display and battery).Now, go ahead and reconnect the LCD cable.Also, reconnect the battery cables. Keep it safe.Start your Asus laptop to confirm that it is now turned on.Even if this doesn’t help, I recommend checking the internal battery as well as both connectors and cables for possible damage.
If it is found to be faulty, you can replace the built-in battery (original battery only).Remove the internal laptop batteryClose the laptop case, tighten each screw, and turn on the Asus laptop. Your device should now turn on.Bonus tip: If you like tinkering with laptop components, you can even pry off the bezel and check for faulty display panels or cables. In some models, you may also need to remove the hinges. Only replace parts if you have the appropriate hardware skills . Since this can be risky for regular users, it is best to head to the nearest service center for professional support.
Check memory moduleMost Asus users have faced this issue after installing incompatible memory modules. For example, if you are trying to increase the RAM on your laptop, you must use the same model (or a compatible model, as described in the user manual).
Faulty or incompatible RAM can cause POST issues. Sometimes, this can even happen due to improper installation of the module. So before jumping to any conclusions, try reinstalling the component, which might resolve your issue.
Shut down your Asus laptop and open the case following the previous instructions.Laptop bottom case disassemblyLocate the RAM slots on your laptop’s motherboard.Pull on the two clips holding the memory module in place.loosen the ram stickOnce you do this, the RAM stick will unlock from its position. After that, you just pull it out of the slot.
