If you were among the group of people experiencing overheating issues with your Alienware Area 51 m15x laptop, then there are some good news for you. A new BIOS update, version X29b P3A30 is now available. The update allegedly allows VGA fans to increase up to 5400 rpm and thus better cool the GPU. To obtain the new BIOS, you'll need to email the m15x support line (L: Area51_m15x@alienware.com). In reply you should receive a link to the BIOS .zip archive. Once you download the small file, Alienware recommends to follow the steps described in the Read full story marker.



Open Nero Ultra Edition, click Backup, and then click “Burn Image to Disc.” Next, select the file “m15x_x29b.iso from the unzipped folder.

• Plug your AC adapter in
• Disconnect all third-party peripherals
• Don’t turn off the computer or restart it during the update
• Don’t eject your DVD/Blu-ray drive during the update.

Steps:

• Open BIOS by tapping F12 during boot
• Set BIOS to boot from your CD-ROM drive first
• Save and exit
• Upon reboot, the BIOS flash update will proceed
• Click “Yes” through the prompts

MSI 5870 BIOS Update

Still can't reproduce. Could you please post the exact BIOSes that produce the issue?

 

Desktop PC boots to black screen after ASUS BIOS update

After searching around Google, I came upon a post where somebody experienced a similar issue and managed to fix it by simply doing the following:

1. Force the PC to shut down
   
2. Unplug the power cord from the PSU for 20-30 seconds; enough so that there's no dormant power left over
   
3. For good measure, if your motherboard/CPU has embedded graphics, temporarily connect your monitor to that instead of your GPU
   
4. Plug the power cord back in and then boot the system
   

Some notes:

• This is strictly for desktop PCs (not laptops). If you're on a laptop,
  you might need to disconnect both the power adapter and the battery
  to completely shut it down
  
• If your system was not bricked because of the BIOS update, you should see a
  message on the screen stating that the BIOS update is resuming, and
  that you should not cut the power to the PC
  
• If the BIOS update was successful, your PC will restart again to a
  vanilla POST screen (not the splash screen) and you will need to
  press F1 here and to set everything in the BIOS back to your own
  
  preferences again
  
• From what I can tell, the BIOS update did succeed after the
  
  flash in the BIOS, but the installation simply glitched out and
  failed to complete the remaining steps after restarting
  

Some things I should've done before I updated my BIOS:

• Saved a copy of my BIOS configurations to a .CMO file in a USB drive
  
• Reset my BIOS settings to default before the update
