☐ 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.
- Identify the cause
Work through these questions step-by-step, using the guides below.
- Is the system getting enough power?
- Is the system failing Power On Self Test (POST)?
- Is the LCD panel dead (for laptops or all-in-one systems)?
- 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').
- Troubleshooting steps for laptops
☐ Remove the battery.
☐ Find an AC adapter.
- If possible, try using an AC adapter that has a higher amperage (A) than required.
☐ 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.
☐ 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.
☐ If the indicator lights come on, but it's still not showing video or POSTing, proceed to the next section.
