If this does not work, repeat the above steps on a different power outlet. The power cord and power brick may also be damaged. To check if they are working, the power brick should feel slightly warm after charging the laptop for an hour. If none of the solutions above worked, the battery may be damaged.

Operating System Failed to Load ¶ 

There may be an issue in the operating system preventing it from loading. Try restarting the laptop. If that does not work, consider doing a system restore.

Failure to Recognize USB Devices ¶ 

The laptop does not recognize devices connected via USB

Faulty USB Drivers ¶ 

In order to allow the laptop to recognize the USB Port Drivers again, a quick reset can be done by uninstalling the USB Port Drivers. Open Device Manager under Control Panel, and select Universal Serial Bus controllers. Right-click the first driver and select Uninstall. Repeat this step for all available USB Port Drivers. Restart the laptop.

Damaged USB Port ¶ 

If the USB port has been damaged, it will not properly recognize devices. In order to regain USB functionality, the USB port must be replaced.

No Internet Access ¶ 

The laptop either fails to connect to a wireless network or cannot access the internet

Wireless Adapter Disabled ¶ 

It is possible that the wireless adapter was accidently disabled. To re-enable it, press the fn key and F2 simultaneously. The laptop should connect to your network automatically if it is a saved connection; if not, sign in manually.

Not Connected to Wireless Network ¶ 

If the laptop is not connected to a wireless network or a router via ethernet, you will not be able to access the internet. If using WiFi, click the wireless icon in the taskbar and log into your wireless network. If using ethernet, connect an ethernet cable between the ethernet port on the left side of the laptop and your router; you should then connect to the internet automatically.

Router / Modem Failure ¶ 

If you are connected to the wireless network but still have no internet access, there may be a problem with either the modem or the router on your network; this often occurs after a power outage. Try resetting both your modem and router by unplugging the power cable from them for 15 seconds, then reconnect them. If this does not restore internet access, try troubleshooting your specific modem or router. Note that some routers have a modem built into them.

Faulty Wireless Adapter Driver ¶ 

If you cannot see any wireless networks or receive error messages, you may have an issue with the drivers for your wireless adapter. Plug your laptop directly into the router via ethernet. Open the device manager and navigate to network adapters. Find the wireless adapter and right mouse click it. Select “Update Driver Software…”, then select “Search automatically” and follow the prompts. Alternatively, use another computer and go to Asus’s support site and download the wireless adapter drivers. Transfer them to a USB drive, and run them on your laptop.

Many computer viruses can cause blue screen failures. To fix this, start your computer in safe mode by pressing F8 while the computer is booting. While in safe mode, run an antivirus scanner (such as the built in Windows Defender) to diagnose the virus, and remove the affected files. Restart your laptop to return to regular Windows mode, and the computer should resume normal function.

Software Issue ¶ 

If you have recently installed new software, it could be causing system failures. To fix this, start your computer in safe mode by pressing F8 while the computer is booting.

Power off the laptop and reseat the memory or hard drive by following the same steps you took to install it. Power on the notebook to see if it works. If it does, then it only needed to be re-seated, and you are done.

If that did not work, try replacing the memory or hard drive with the original component. Power on the notebook to see if it works. If it does, then the component was incompatible with the laptop.

If you have not replaced any components in the laptop, you may have a faulty hard drive or RAM. You can run MemTest86 ( to determine if the RAM is faulty. If the memory is fine, you can run HDDScan ( to determine if the hard drive is faulty. If either fails, that means you will need to either replace the RAM or replace your hard drive.

Out of Date BIOS (Motherboard Firmware) ¶ 

An out of date BIOS can cause system failures. You can use Winflash to apply updates to the BIOS. Refer to pages 74 and 75 of the user manual for more information. Ensure the laptop does not lose power during the BIOS update.

Total System Failure ¶
