Laptop Does Not Power On ¶ 

When the power button is pressed, the laptop fails to boot to Windows.

Power Supply is Damaged ¶ 

Make sure that the power cord is plugged into the outlet properly and the power brick is plugged to the laptop. Allow for the laptop to charge for an hour and then attempt to power on. 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. Replace your battery using the guide found here.

USB Device and/or SD Card Interference ¶ 

USB devices and/or SD cards can interfere laptop from booting. Attempt to power the laptop on after removing all connected USB device and/or SD cards.

Laptop is Overheated ¶

Power Light is On, But Screen is Off ¶ 

When turned on, the device shows the POST screen, but the screen turns black while the power light stays on.

Screen Brightness Set Too Low ¶ 

The brightness may have accidently been set very low, making the screen appear black. Attempt to increase the brightness by pressing the fn key and F6 several times. If the problem persists, this could indicate that the screen is damaged and needs to be replaced.

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.

Blue Screen (Fatal System Error) ¶ 

‘The laptop crashes and displays a blue screen with an error message.

Virus ¶ 

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. Go to the control panel and select “uninstall a program”. Select the new software and uninstall it. Delete any remaining files from the software after uninstalling it. Restart your laptop to return to regular Windows mode, and the computer should resume normal function.

RAM / Hard Drive problem ¶ 

If you have recently replaced the hard drive or RAM, it may not be installed correctly or is incompatible with the laptop.

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 (http://www.memtest86.com/) to determine if the RAM is faulty. If the memory is fine, you can run HDDScan (http://hddscan.com/) 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 ¶ 

If the problem persists, perform a system reset as a last resort. This will restore your laptop’s operating system to its default configuration. Back up any files you wish to save before beginning, as this will delete everything from the hard drive. To do this, restart your laptop and press F9 during POST (Power-On-Self-Test). Wait for Windows to load and select “Troubleshoot”. Select “Reset your PC”. Select “Fully clean the drive”. Press reset. Ensure that the laptop does not lose power during the reset process.

Touchpad is Unresponsive ¶ 

The touchpad either does not respond to touch, or the cursor moves erratically

Touchpad is Disabled ¶ 

The touchpad may have been accidently disabled using the function keys. To enable it, press the fn key and F9 simultaneously.

External Device Interference ¶ 

Some external USB devices may interfere with touchpad operation. Try removing all connected USB devices.

Faulty Drivers ¶ 

Faulty touchpad drivers may cause the touchpad to become unresponsive or behave erratically. Using either the touch screen or a USB mouse, go to the control panel. Select “Hardware and Sound” and then select “Device Manager”. Under “Human Interface Devices”, find the touch pad. Right mouse click on it, and select “Update Driver Software...”. Select “search automatically for updated driver software”, and follow the prompts. If drivers are not found, download the drivers from Asus’s support site. Extract the zip file, run “setup.exe” and follow the prompts.

Laptop Shuts Down Unexpectedly ¶ 

The laptop unexpectedly shuts down with a charged battery.

Dust in Fan ¶ 

The laptop may be overheating due to excessive dust in the fan. In order to clean it, first power down the laptop. Identify the fan and use compressed air to break the dust loose. Once power is restored, the fan will blow out the loose dust.
