As there is no display but the power leds are glowing on the notebook, we cannot perform any troubleshooting steps otherthan Power drain.

Here are is the Power drain procedure:

Try doing power drain by taking out the battery & keep holding down the power button for complete one minute to drain out the power from the computer components. Restart the computer after putting the battery in.
Try restarting the computer only with the AC power, without the battery & vice-versa.

That should resolve the issue. If the issue persists, then you need to contact HP if your notebook is underwarranty. if there is not warranty, you have to contact service center.

Note: There is difference between removing/replacing the battery and power drain. Power drain should resolve the issue.

My nx7300 is not booting up. I have some lights that go on and the fan is running, but no screen, and no keyboard functions. The battery is about 1.5 years old

Try resetting the ram, ie remove battery, press on button a few times to de-enrgise system then remove cover under laptop (Be very careful not to lose the tiny screws) gently ease ram stick(s) out then replace. Ensure the battery charger is also plugged in as you may have very low battery.

Bios update


I am not sure after installing which update the display has gone. I mean Windows update or HP software update or BIOS update.

Let me take the senario of the BIOS update and assist you in this regard.

If the display has gone after installing the BIOS update, then the issue cases are 1. Installed wrong BIOS update 2. Notebooks might have restarted or hanged while installing the BIOS update.

In both the cases BIOS will get currupt and there will be no display on the notebook.

Solution for the issue is: If you notebook is under warranty, HP will arrange for mail-in repair, plss contact HP. If the notebook is out of warranty, then you need to contact HP authorized service center.
