Sony Battery Fix
Some SONY notebooks do not work with newer batteries, including replacement batteries from Energy+ as well as new SONY batteries. This is due to changes in the programming that lives in the charge control circuit in newer batteries. The solution involves using a SONY supplied firmware update to the bios of the notebook so it will talk to newer batteries.
We have linked to this bios updater for your convenience. (see below)
Sony BPS8/BPL8,/BPS9/BPL9,BPS10/BPL10,BPS11/BPL11/BPX11 battery drivers can be installed on Windows XP/Vista/7 32 bit operating system; for Sony BPS12/BPS13/BPS14/BPS15/BPS18/BPS22 can be installed on 32 and 64 bit operating system.
Please disable any antivirus software and firewall prior to driver installation.
For Windows XP systems, run the software as instructed.
For Windows Vista or 7 systems, you must login as the "Administrator" user prior to installation or "Run as administrator" for step 1.3 below.
Do not interrupt installation once started. A typical install takes 5-15 minutes depending on laptop configuration (i.e. operating system, software, firewall, etc... ). Interrupting the installation could cause total permanent system failure. You will be solely responsible for this if you unplug the computer, or reboot it before the installation is complete.
If this happens, you will need to contact SONY directly to discuss if your computer is repairable. Any charges incurred will be your own responsibility.
