If your HP Elitebook won’t turn on, I have an easy fix. We used them at a previous job and I taught this trick to all of my coworkers who had difficulty getting theirs to power up in the morning. It’s easy, and takes less time than calling the helpdesk, and less time than going direct to desktop support too (which they love, I’m sure).
First, unplug the AC adapter from the laptop and/or undock the laptop.
Next, flip over the laptop and slide the latch open to release the battery. Pull the battery out and set it aside.
Now, for my magic trick. Flip the laptop over, open the lid, and press and hold the power button for at least 15 seconds. I generally go the extra mile and hold it for more like 30.
Now you can replace the battery. Dock the laptop or plug the AC adapter in, and try the power button again. Chances are, your laptop will fire up now.
And that’s all there is to it when an HP Elitebook won’t turn on.
If you have a problem with your Elitebook overheating, here’s how to fix an Elitebook 8440 that overheats. It’s not usually a difficult fix either. Other models of Elitebook will be very similar.
I’ve written about this trick before, and it’s not always necessary on all hardware, but it definitely helps Elitebooks when nothing else will. This trick works on other HP laptops as well. For that matter, it works on any other brand of laptop with a removable battery.
What about desktops?
Desktop computers are a bit different. And if you’re wondering, there’s nothing especially different about HP desktops in that regard.
