Alienware M15x performance drop...AGAIN!

Need to go to the Dell support page and search for drivers using your service tag. This should list all the drivers for your Laptop, including the current BIOS version. My M15x is only 6 months old and was delivered with the A06 BIOS version, current version is A08 and is designed to address the throttling issue experienced when using the higher end CPU and GPU. You will need to use a USB stick (2G max size) to complete the update.

The BIOS is basically the software loaded onto the motherboard chips and controls the basic settings such as RAM voltages and FSB speeds. Its not difficult to update and the instructions are very good. If you have made any changes to the BIOS setup since delivery then the BIOS update will undo these, i decided to take a picture of each BIOS setting screen before updating as a reference. The BIOS is critical for the system to operate, if it becomes corrupt during an update then the computer probably wont even start up. If you have any important work stored on the HDD then back this up first in case you experience an issue during update and end up returning the laptop for repair.

Oh, use a clean USB stick, in fact i think the stick is cleared during the update procedure. Can't remember so i would start with a formatted USB.

Have you installed any new software packages recently that may have slowed down the system performance. I used to find that packages like Norton and Mcafee were to invasive and would kill performance.
