Upgrade of my HP Compaq 6910p laptop



Finally the Upgrade of my HP Compaq 6910p laptop is completed. 
Complete refurbishment/upgrade performed over the last months:
-new battery pack
-secondary battery pack installed.
-Belgian French keyboard replaced with German keyboard.
-exchanged the 2GB RAM with 8 GB RAM (2x4GB)
-tossed out 160 GB HDD and replaced with Samsung 250 GB SSD (latest firmware applied).
-replaced 65w PSU with 90w PSU.
-Applied latest HP BIOS but a modified version with network card support whitelist removed.
-Sierra 3G/HSDPA card installed. Applied latest firmware to go from a 3.6Mbps peak rated device to a 7.2Mbps peak rated device

Getting the 

HG Sierra UMTS 3G HSPDA PCI-E MC8775 unlocked Card

 is not eaasy as it first requires applying a new modified BIOS to remove the whitelist (more about this later) and then you come across 3 other issues:

-The card requires applying the latest firmware to ensure it works in highest speed, but the download links in the blog article with the soution are down
-The card only works with Sierra Wireless' "AirCardWatcher" dialup tool but it's not obvious at first that you require it or where to get it from
-Sierra Wireless offers zero end-user support.


This blog post will help you to get around.


So once you have successsfully applied the modified BIOS with the whitelist removed,.read the blog post here: 3g modem wiki entry for this card

The tool and firmware can be found here

The neccessary driver for this card can be found at the HP homepage here

Last but not least you can find the AirCardWatcher General program here.


Despite that the drivers are from 2008, they just installed and work fine under my Windows 8.1. Update 2! :)


The BIOS for the HP Compaq 6910p without whitelist can be found here: here -click-

Make sure you install the one with the right chipset!

If after the update you receive an info that the BIOS update failed, then you may need to downgrade to the version f17 or f15  first and then re-apply to f19


Hope this helps! :)
