Hi @Eman28,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you're dealing with a hardware-related issue. Error 502 on HP laptops generally points to a hardware problem, and it can sometimes be related to the battery, but there are a few steps you can try to troubleshoot.

Reset the BIOS:

• Power off your laptop.
• Turn it back on and repeatedly press the ESC key until the Startup Menu opens.
• Press F10 to enter the BIOS setup.
• Once in BIOS, look for an option to "Reset to Default" or "Load Setup Defaults" and select it.
• Save and exit BIOS, then restart your laptop.

Check Hardware Connections:

• If you’re comfortable opening up the laptop, ensure that all internal connections are secure, especially the battery and storage drives.
• Sometimes, loose connections can cause error messages.

Perform a Hard Reset:

• Power off the laptop and disconnect the power adapter.
• If the battery is removable, take it out.
• Hold the power button for about 15-30 seconds to discharge any residual power.
• Reinsert the battery, connect the power adapter, and power on the laptop.

Run Diagnostics:

• HP laptops often have built-in diagnostics tools. Restart your laptop and press ESC repeatedly to access the Startup Menu.
• Select F2 to run the HP PC Hardware Diagnostics.
• Run a full system test to check for any hardware issues.

Update BIOS and Drivers:

• If you can access the laptop, try to update the BIOS and all drivers. Sometimes, outdated firmware or drivers can cause hardware errors.

I hope this helps.

Take care and have a good day.
