- Step 4: Reconnect the battery and power adapter, then try turning it on again.
2. Boot in Safe Mode
If your computer shows the HP logo during startup but fails to proceed, a software issue may exist. Boot your laptop in Safe Mode to troubleshoot further:
- Step 1: As you turn on your laptop, repeatedly press the F8 key until you see the Advanced Boot Options menu.
- Step 2: Select “Safe Mode” and press Enter.
- Step 3: If the laptop boots in Safe Mode, you may have recently installed software or drivers causing the problem.
System Recovery Options
If all else fails, you may need to consider restoring or resetting your system.
1. Use System Recovery Tools
HP laptops come with recovery options that can assist in restoring your laptop to a previous working state. Here’s how:
Boot from Recovery Media: If you created recovery media previously or have a recovery partition, you can boot from it to access recovery options.
Perform a System Restore: Choose an earlier restore point to revert to a functional state.

What should I do first if my HP EliteBook laptop won’t turn on?
If your HP EliteBook laptop won’t turn on, the first step is to ensure that it has power. Check if the power adapter is securely connected and the power outlet is functional. Look for any indicator lights on the laptop; if they’re not on, try a different outlet or use a known working adapter. Additionally, you might want to perform a hard reset by removing the battery (if it’s removable), disconnecting the power adapter, and holding down the power button for about 15 seconds.
Once you reassemble everything, reconnect the power adapter and try turning the laptop on again. A hard reset can often resolve minor issues by clearing any temporary configurations or errors that might be preventing startup. If the laptop still doesn’t power on, you may need to explore further troubleshooting steps.
How can I check if my power adapter is working?
To check if your power adapter is working, start by inspecting the adapter itself for any visible damage, such as frayed wires or burn marks. If you have access to a multimeter, you can test the voltage output of the adapter to ensure it’s delivering the correct amount of power. This is essential because a malfunctioning adapter can deliver no power or insufficient power to the laptop.
Additionally, you can try using a different compatible power adapter to see if your laptop turns on. If the laptop powers up with the alternate adapter, then your original adapter may need to be replaced. If neither adapter works, the issue might lie within the laptop itself rather than the power supply.
What are some common signs of a hardware issue?
Common signs of a hardware issue with your HP EliteBook include unusual noises when attempting to power on, such as clicking or beeping sounds, and failure to get past the initial boot screen. If the laptop’s LED indicators appear but the screen remains black, it could point to a display issue.
