If you have ever had a problem with your Gateway laptop computer booting up, you know the worry that ensues. All of your documents, pictures and business invoices gone, trapped inside the box that is your computer. Not all hope is lost. It is worth taking a deep breath and learning the basic troubleshooting steps.
If the computer has power problems, make sure the battery has the minimum charge needed to function if it is not plugged in. If you are plugged in via the power supply, you should check the adapter to make sure it is working and that all wires are plugged in and not damaged in any way. If the adapter is fine and the computer still does not respond, try different outlets to ensure that the one you are using is functioning. Try plugging another device into the wall outlet to see whether it works. If the computer fails to turn on at this point, you may need to change the power supply.
If you are not getting video, plug in an external monitor to see if the internal LCD is functioning. If the external monitor displays video, the internal one is faulty, or the internal cables connecting the LCD to the motherboard have become loose. If there is not any video from the external monitor, try changing the RAM of your computer. RAM that is faulty can cause video problems. If all this fails, the graphics may need to be replaced.
If you are not getting any response from the operating system, your hard drive may be faulty. Try starting your computer from the operating system CD. Make sure to choose the operating system installed on your computer. If the hard drive appears as a destination to install the operating system, try to reinstall the operating system. Check to see if the operating system on your computer allows a reinstall without erasing the hard drive. If the hard drive does not appear from the installation CD, take out the hard drive and boot it through a sled, which is a small device that allows you to boot your internal hard drive like an external one. If you can't access the drive, the drive is dead. Take it to a data recovery specialist.
