[Solution] M18x R2 Fails POST with 8 Beeps Switching Graphics Mode from IGFX to PEG

Jump to solution

During a recent Windows 8 clean install, I discovered a problem after installing the Intel HD4000 driver and attempted to switch from IGFX (integrated) to PEG (discrete) graphics mode using FN+F7. As soon as I attempted to do so, my M18x R2 would not boot and starting the 8-beep nightmare. Through the process of elimination, I was able to determine the cause. I had Dell Community member johnksss verify this with his M18x R2. I am sharing it here to help others that may encounter the same issue. The problem consistently occurs with one incorrect BIOS setting, and the fix is an easy one.
 

Issue: M18x R2 fails POST with 8 beeps attempting to switch from IGFX to PEG mode using FN+F7

Cause: BIOS setting for Non-Turbo Flex Support is “Enabled”

Solution: Leave setting “Disabled”

Corrective Step: Clear CMOS to restore default BIOS settings

How to clear CMOS:

  • Disconnect AC adapter
  • Remove system battery
  • Remove bottom cover
  • Disconnect CMOS (coin cell) battery
  • Depress power button 30 seconds
  • Bridge pins for CMOS battery terminal with screwdriver (be gentle - don't bent the pins)
  • Reconnect CMOS battery
  • Connect AC adapter
  • Power on - if you get 5 beeps, don't panic... This is common. Power off and on again and you should be fine.
  • F2 to enter BIOS. Set date/time, any custom settings (be sure to leave Non-Turbo Flex Support "Disabled")
  • F10 to save and exit setup
  • Power off
  • Reinstall bottom cover and battery


I hope others find this information helpful. Hopefully, this will save a few unnecessary motherboard replacements.

Yes! My laptop is no longer a $3000 paperweight! Thank you so much! Twice I've had this issue and this was the only solution that ever worked for me. I went through countless forums and no one had any solutions, until I came across this one. Thank you so much for your help!

Nice! Glad that I was able to provide something helpful. And thank you for taking a moment to say so. I appreciate it.

I am fairly confident that Dell/Alienware has replaced at least a few motherboards on systems exhibiting this behavior when all they really needed was this simple fix.

I wish this would help me.

I'm having the same problem on an alienware m17x r4 machine that I just had returned after a repair at the dell repair depot and it does this once in awhile along with 6 beeps and 5 beeps sometimes too.

 

I don't have this option in my BIOS to change it, so I'm guessing something is totally messed up again.  Had the problem persist since getting my machine back from the depot (Worse then when I sent it to boot).  Going to have to send it back again.

It sounds like you are experiencing a different problem that is fairly serious. This particular tip is only a setting that needs to be changed rather than an actual hardware problem.

Good luck and I sincerely hope that gets fixed for you very soon.
