Over the past couple of weeks I've been blogging about throttling issues on some of our Studio and Studio XPS model laptops. These throttling issues resulted in power and performance issues which vary by degree, depending on configuration. Previously, I wrote about how Dell has resolved the issues for our Studio XPS 1645 and 1647 models. This blog post focuses on how Dell is resolving this problem for our customers with Studio 1747 laptops.
Earlier this week we released BIOS version A08 for the Studio 1747. This BIOS update adjusts the algorithm that is used by the Studio 1747 to control the CPU, and allows the use of increased power available from a 130-watt AC adapter. While we don't expect many Studio 1747 customers will experience throttling issues (similar to the Studio XPS 1647) with their systems, those who do can see enhanced performance of their systems while using the larger ac adapters. We feel that this improved algorithm will greatly improve performance on the Studio 1647 systems. Further, in conjunction with the 130 watt adapters for those who need them, the improved algorithm can remove almost all throttling from these systems. Thermal limitations remain to protect the graphics card from excessive heat, if needed, during some intensive use.
From customer discussions on our forums we also learned that quite a few of our 1747 customers have been reporting that the 90-watt adapters may be overheating. As I posted previously on our forums, those Studio 1747 customers experiencing overheating on their adapters, as well as those concerned with CPU throttling on their systems after updating to the A08 BIOS, can contact Dell Technical Support to request a replacement 130-watt adapter. If you have questions about how to update your system to the latest BIOS, our Technical Support reps can help you perform the upgrade.
If you have any questions about throttling in the Studio 1747 we invite you to join in the discussion on our Dell Community Forums.
