Introduction

The battery within a laptop is the most important component to having a functioning laptop. If you are experiencing a poor battery lifetime in your HP Elitebook 840 G5, then please follow the step-by-step replacement guide for the battery below. As this replacement requires the backing to be completely removed, use caution during the replacement as the electrical components inside of your laptop will be exposed. Also ensure to carefully remove any connecting wires by the heads-not the wires themselves. This will prevent any wires from breaking during the replacement.

What you need

Step 1

              Back Cover

Use a Phillips #1 screwdriver to undo the five screws. The top three screws are 10 mm and the two side screws are 7 mm.
Unscrew the bottom three screws using the same screwdriver.
The bottom Phillips #1 screws don’t remove from the back plate, but do need to be unscrewed.
Some models have a slightly different screw configuration, shown in the second photo.

Step 2

Turn computer so that the hinged side is facing up.
Use the plastic opening tool to pry open the back plate.
Drag the plastic opening tool along the edge from left to right and use a second opening tool to pry open the top right corner.
Repeat the 3rd step for the other side.
Repeat on Left and Right sides of the system. There are two points in the middle (on the left and right sides of the center screw) that will release with slight lifting pressure.
You should be able to hear a pop when prying open the corners.

The battery shown in the photo is a TT03XL. My HP Elitebook 840 G5 laptop has a SS03XL battery. Before you order your replacement battery, take off the laptop’s bottom cover and confirm the battery model you need.

Unfortunately, the TR9 Torx Security Screwdriver did not work on my Elitebook 840 G5. It is unclear if this is due to the battery model. Mine is a SS03XL battery.

I also got caught up in this battery fiasco.

Daniel A. Barcenas Jr - Mar 20, 2022

Replaced the battery with the correct SS03XL battery sold from here and have had zero luck in getting it to charge. Updated bios, firmware, everything under the sun, drained the system of residual power. Disconnected CMOS battery because I’m reaching for anything at this point. Bios diag options doesn’t even list battery diag as an option. Battery is not detected. I’m at a loss, help pls.
