Asus Eee PC 900 Laptop Troubleshooting

In the event that the laptop is not powering on

• Check the adapter's light (if it's off then your cord is broken)
• If your computer is beeping, look at your laptop's support page for what the beeps indicate. If not then continue down the list.

• Check the display lights and listen for the fans and hard drive (if nothing happens it's likely your battery is malfunctioning)
• Remove the battery and try running the lap top from a plugged in power supply

Installing a new battery may be done by following our battery installation manual.

In the event that the laptop powers on but does not boot, experiences memory problems, or contains hard drive errors

If the computer won't boot, the CPU is unable to communicate with hardware. The cause can be improper installation or failure of the BIOS to recognize hardware. The hard drive may be defective. Refer to our hard drive installation guide for replacement.

Check the software documentation for minimum memory requirements. It may be necessary to buy more memory. Reseat the memory modules to make sure the computer is properly communicating with the memory. Our RAM installation guide describes how to install new RAM modules into your computer.

You may have the wrong parts for your computer so the computer does not function correctly. Make sure to check the parts are correct. At the manufacturer's website you can look up the part numbers to check if you have the right parts.

The memory module itself may be defective. For defective hardware, refer to this installation guide to remove and replace the defective RAM.

In the event that the laptop's display is malfunctioning

If the display is too bright or too dim, press the "Fn" button and F3 to darken of F4 to brighten. If this does not work, it is possible to manually change your display brightness in Windows OS through using the Control Panel => Display => Adjust Brightness (Windows 7). If display problems persist, follow our display installation guide to replace the screen.

Spots are often damaged pixels on the screen. Try wiping the screen with a microfiber cloth and a light glass cleaner to ensure that the spots are not dirt particles. If the spots remain, follow our display installation guide to replace the screen.

If the display does not turn on, ensure that power has been turned on. If power is on and screen is still off follow our screen installation guide to replace your or re-seat screen.

In the event your webcam is malfunctioning

Check to make sure that your camera is set to its maximum quality settings. If your settings are at maximum check to make sure your connection to the internet is good. If your connection is good, and the quality is at maximum, clean the lens with a soft microfiber cloth. If problems continue, refer to our webcam installation guide to replace the webcam.

Ensure that your webcam is turned on. If the camera is turned on and is still not functioning, refer to our webcam installation guide to replace it.

In the event that either the trackpad or clicker buttons are malfunctioning

Check your mouse settings. In a Windows OS, this setting can be found in Control Panel => Mouse => Pointer Options.

Multi-touch gesture problems are most often a software, rather than hardware, issue. Update youre trackpad driver through Asus Support. If the problem persists, trackpad replacement may be necessary using our touchpad installation guide.

With use, the trackpad will acquire gunk and filth on its surface which hinders its sensitivity. To clean this gunk, gently rub the surface of the trackpad with a soft cloth dampened with rubbing alcohol. If the problem persists, continue reading.

In the case that mouse movement is impossible with the track pad, try reseating the trackpad's input housing using our touchpad installation guide. If the the trackpad is still unresponsive after reseating, replacement of the trackpad will be necessary.

If using a Windows OS double-click speeds may be altered to user preference by going to Control Panel => Mouse => Buttons => Double Click Speed.

If the either, or both, clickers are unresponsive, use a can of compressed air to try to dislodge any debris under the clickers. If the problem continues, follow our touchpad installation guide.

In the event that one or more keys do not register, or incorrectly register, when pressed

Debris or a sticky substances may interfere with the mechanical switches of the keyboard. Obstructions may cause key presses to be ignored or incorrectly register. Use a can of compressed air to try to dislodge the debris. If that does not work, continue reading.

• In the case of keyboard failure, plug in an external keyboard via USB port and test if the external keyboard's inputs work in comparison to the laptop's keyboard.
• In the case that the external keyboard's inputs work, but the laptop's keyboard continues to not work, refer to our keyboard replacement guide.
