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.
Charging Problem - Elitebook 6930p 09:54 PM. I have an external battery to supplement the one always docked in the computer. When I plug my charger in, my external battery gets charged, but the main battery does not. † The opinions expressed above are the personal opinions of the authors, not of HP. By using this site. The power LED, located near the power icon, glows while the battery is charging. Unplug the power adapter cord from the notebook. Press and release the Power button to start the computer using only the battery as the power source. If the computer powers on, the battery is functioning.
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.

What to do if the battery light flashes and doesn’t turn on
If the orange light flashes briefly and the computer still doesn’t turn on, that means the battery is dead and the computer can’t get power. This means the battery isn’t charging from the AC adapter. Check to make sure the AC adapter is plugged firmly into the computer or docking station, the power cord is firmly plugged into the AC adapter, and the other end of the cord is plugged firmly into the wall. If you dock the computer, make sure it’s firmly seated in your docking station. A too-loose connection in any of those places will cause the battery to not charge and eventually run out.
Checking and fixing all of these things should only take an additional minute, if that.

Interestingly, it is supposed to only flash if the critically low battery is the exclusive power source. To quote the manual: Amber: A battery is charging. White: A battery is close to full charge capacity. Blinking amber: A battery that is the only available power source has reached a low battery level.
One more thing
If it still won’t turn on, the laptop may be overheated. 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.
How to Extend HP EliteBook 6930p Laptop Battery Life
Laptop computer batteries often run out of power sooner than would be desired. Here are some tips for making them last longer between charges...
Screensaver: Change your laptop's screensaver to a blank (Black) screen,and set it to turn on within a few minutes of inactivity. Screensavers with graphics and sound effects will drain the power more quickly,whereas a blank screen will conserve power.

Hard Drive & Disk Drive: Avoid using the hard drive and disk drive excessively. Because these are mechanical mechanisms,they consume more power. In some cases,upgrading the amount of memory will reduce hard drive usage. If your HP EliteBook 6930p laptop is set to run anti-virus scans periodically,only allow this to happen when you have it connected to AC power,because this substantially increases hard drive usage while it is running. If you are using an older laptop with no hard drive,consider using a VDISK or RAMDISK to reduce disk drive usage.
Sound/Music: If you want to listen to music while operating the computer,consider using a separate radio,cassette recorder,or CD player. If the CD player's batteries run out,you will be able to keep using the computer,which is probably your higher priority.
USB Devices: If your HP EliteBook 6930p laptop computer has a USB port,keep in mind that some USB devices draw power from the computer's battery while they are plugged in to it. Avoid leaving such devices plugged in longer than they need to be.

Software: Different software which accomplishes the same functions may cause your HP EliteBook 6930p battery computer to use different amounts of power. If the software utilizes memory more effectively (rather than reading/writing to the disk or hard drive frequently),it may use less power. Software which places less demand on the processor can also reduce power consumption in some cases,along with programs which use a dark-colored background. Avoid running software directly from a 3.5' disk or CD-ROM,because it will cause these mechanisms to run frequently and drain the power more quickly.
