Need to replace battery and keyboard

Hi @Lucky157,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand you need to replace an old battery and keyboard on an HP laptop. Let’s go through the best way to approach this safely and correctly.

Identify the exact laptop model
Check the full model name on the bottom label or in Settings > System > About.
Battery and keyboard compatibility depends entirely on the exact model and series.

Confirm whether the battery is internal or removable
Most newer HP laptops use an internal battery, while older models may have a removable one.
This determines whether replacement is user-serviceable or requires opening the laptop.

Check HP documentation for part numbers
Go to the HP support page for your model and look under Parts / Maintenance & Service Guide.
This provides the correct HP spare part numbers for both the battery and keyboard.

Decide on replacement method
If the battery and keyboard are listed as Customer Self-Repair (CSR) parts, you can replace them yourself.
If not, replacement still may be possible, but it requires careful disassembly.

Prepare for replacement
Power off the laptop and unplug the charger.
If internal, disconnect the battery first after opening the bottom cover to avoid damage.

Battery replacement tips
Use only the correct voltage and capacity battery specified for your model.
Avoid generic batteries without HP-compatible part numbers, as they can cause charging or lifespan issues.

Keyboard replacement tips
On many models, the keyboard is secured from underneath and requires removing the bottom cover, battery, and sometimes the motherboard.
Take note of ribbon cable connections and locking tabs before removal.

Test after replacement
Once installed, reconnect the battery, power on the laptop, and confirm charging and keyboard input work normally.
Run HP Diagnostics to verify battery health.

If unsure about disassembly
If the laptop has an internal battery and top-mounted keyboard, replacement can be complex.
In that case, using a professional repair service may prevent accidental damage.

I hope this helps.
