How to Troubleshoot a Notebook Computer
Notebook computers have their own sets of problems apart from desktop computers. A notebook's internal components are much smaller, more integrated and installed closer together than those in a desktop, and are thus more prone to problems. The first thing in discovering what is wrong with the notebook is to determine if the problem is software- or hardware-related. Most hardware problems are best resolved by a computer repair shop; software problems can oftentimes be fixed without expensive repair shop bills.
Just as human health problems are diagnosed by symptoms, computer problems can be diagnosed in the same way. Start small and go through the process of elimination when troubleshooting your problem. For example, your notebook may suddenly shut down. Before you decide that the notebook needs a new hard drive, check for malware or a faulty fan first.

Check the power supply. Plug in the notebook using the AC power supply, and turn on the notebook. Look for LED display lights or any machine noise (such as a fan running). If you see no LED lights and hear no noise, it is most likely a problem with the power supply. The fault can be either inside the notebook (where the power connector is soldered to the motherboard) or the AC power cord itself.

Listen for unusual sounds, such as grinding, clicking or squeaking. Clicking or grinding usually denotes a hard drive problem; a squeaking sound signifies a faulty fan.

Check the monitor display. If the display on the monitor blinks in and out, this may signify a loose connection to the video cable connector. To test this, shut down your notebook. Plug in a separate, external monitor into the VGA port of your notebook, and boot up the notebook. If the external monitor shows your notebook image, the problem is related to the notebook monitor. If the external monitor responds similarly to the notebook monitor, the notebook may have a driver or memory problem.

Watch the behavior of the notebook. If it powers on normally but shows erratic behavior (such as shutting down and booting up, or displaying multitudes of browser popups), the notebook may have a virus. Scan the notebook for viruses and malware. Follow the manufacturer's instructions for removing them.

Check to see if software programs are operating correctly. If the notebook displays a frequent "Blue Screen of Death" or the software programs frequently "freeze," check your computer manufacturer for BIOS updates and driver updates. If you use Windows, make sure you have the latest Windows Updates installed.

Tips & Warnings
If possible, back up your computer data before taking your notebook to a repair shop.
Never open the case to your notebook without releasing static electricity from your body. Static can destroy the notebook's sensitive internal components.
