HP 9470M - Will not boot to BIOS/OS, power indicator light stays lit, charging indicator flashes

[ Edited ]
Product Name: HP 9470M
Operating System: Microsoft Windows 7 (32-bit)

Issue Symptoms

Laptop does not boot in any way (to the BIOS, to the OS, anything).

Power button indicator light acts like laptop is powered on constantly (lights up white at all times).

Front charging indicator light flashes between white and orange.

The issue occurs in all power configurations (plugged in with no battery, plugged in with battery, and battery only).

 

Attempted Solutions

Removed battery and held power button for 30+ seconds to dissipate any leftover electrical charge.

Removed and reseated battery, power cables, CMOS, and hard drive.

Removed all dust and debris from laptop.

Attempted to power on using different batteries and chargers.

 

Any suggestions?  The unit is no longer under warranty so I am unable to return it to HP.

Hello @JonathanPepper,

 

You might want to take a look at this document: Battery Does not Power Notebook or Hold a Charge.

 

It suggests troubleshooting steps to determine if the problem is the battery, the power supply, or the system board.

You might find the answer to your battery/power issue as you work through the steps in that HP support article.

I forgot to mention in the original post that the machine had been tested with multiple different batteries and chargers.  I have edited it to reflect this information.  

 

I was afraid it was the system board going out, but thought I'd post on here before giving up hope.

 

If anyone has any other suggestions based on the symptoms that I provided in the original post, please feel free to let me know.  Otherwise, I'll just start looking into replacing the machine.

 

Thanks!

Your BIOS is likely corrupted, and needs to be recovered. For this, you would need to make a call to HP support, and there may be a fee since it is out of warranty. An HP authorized service partner should also be able to assist.
