HP Recommended

Hi, please help me.

My HP EliteBook 845 G7 notebook will not power on.

The power LED light is flashing, and the Caps Lock button stays solid white. When I try to hard reset it by holding the power button, it switches off, but as soon as I release the power button, the Caps Lock light turns back on and the LED starts flashing again.

I think this happened after a failed BIOS update, and I also received a message about the HP Endpoint Security Controller.

Sometimes I manage to get it to work by disconnecting the battery from the motherboard and “tricking” it into booting. The trick is: with the battery disconnected, I plug in the charger and the Caps Lock lights up. Then I hold the power button until the Caps Lock turns off, and while still holding the power button, I unplug and re-plug the charger. Sometimes, when I do this, the Caps Lock stays off and the laptop boots normally.

Please help me figure out what’s going on. I went to a computer repair shop and they said they couldn’t fix it.

I really need this laptop to work again—it’s my source of income.
