If your Dell Latitude 7280 won’t turn on, you may be experiencing no POST and boot problems. To troubleshoot and fix this issue, follow these steps:

Solutions for No Video Display
If your Dell Latitude 7280 is not displaying any video, there are a few solutions you can try to troubleshoot and fix the issue.
First, check the power source and make sure the AC adapter is properly connected to both the laptop and a working power outlet. Sometimes a loose connection can prevent the laptop from turning on.

If the laptop still does not display any video on the external monitor, try removing and reseating the RAM modules. Sometimes a loose connection can cause display issues.
Performing Hardware Diagnostics and Hard Resets
First, try performing a hard reset by:
– Disconnecting the AC power adapter and removing the battery.
– Pressing and holding the power button for about 30 seconds.
– Reinserting the battery and reconnecting the AC power adapter.
– Attempting to turn on the laptop again.
If the laptop still does not turn on, you can try running hardware diagnostics to identify any potential issues.
