Template:Laptop POST Troubleshooting

&#9744; Try powering the system on; if it shows the manufacturer's splash screen, you're likely good to go. However, in many cases, some troubleshooting is needed to figure out why a system isn't powering on. Work through these questions step-by-step, using the guides below.
 * Identify the cause
 * 1) Is the system getting enough power?
 * 2) Is the system failing Power On Self Test (POST)?
 * 3) Is the LCD panel dead (for laptops or all-in-one systems)?
 * 4) Is the graphics card or motherboard failing?


 * 1. Is the system getting enough power?
 * Symptoms
 * The screen or monitor remains dark.
 * None of the indicator lights turn on (no 'signs of life').

&#9744; Remove the battery. &#9744; Find an AC adapter. &#9744; Check to see if any indicator lights turn on after connecting the adapter. If the lights remain dark, try using a couple of different adapters. &#9744; If you still aren't seeing any indicator lights after this step, then this system is dead. Consult your instructor to see if it should be recycled, or saved for parts. &#9744; If the indicator lights come on, but it's still not showing video or POSTing, proceed to the next section.

 * If possible, try using an AC adapter that has a higher amperage (A) than required.
