| Save Battery Life, Install Windows XP Patch |
At least as far back as July of last year Microsoft knew that there was a bug in Windows XP SP2 that could drain life from a portable computer's battery if a USB 2.0 device like an external hard disk drive or an internal TV tuner/video capture card was connected and turned on. The device didn't actually have to be doing anything, it just had to be there and powered on.Microsoft announced the problem to OEMs and others, but not to the general public. The company also released a simple patch for the problem. Microsoft said it was concerned that the patch did not go through extensive testing and that it might do more harm than good. So it was not made available to the general public.
Our friends at Tom's Hardware Germany discovered and confirmed the battery drain problem. The staff at TG Daily interviewed folks at both Intel and Microsoft to get the facts and uncovered an explanation for the problem. I did tests on a number of laptops and notebooks and replicated the problem. We were able to get our hands on the early patch, which I tested and found to work fairly well.
