Question about Alienware PC Systems Alienware m15x Gaming Notebook

1 Answer

Have the Alienware M15X laptop and I kept getting the IRQL Less or Not Equal error and I thought it was my Buffalo 1TB external drive, because I would get the blue screen after it lost it's connection to the drive. I thought it was the problem and thought it was a SATA issue, so I changed the BIOS setting for SATA to ATA as oppose the ACHI setting, now I regret doing that because now it doesn't boot up, instead it fires up for a second, the keyboard lights up, the fans run and then shuts down, does this a few times then just stays on with no picture but keyboard is lit up with no functionality, is there a reset to get it to at least get to the BIOS and I can change the SATA settings back?

    I pretty much did the same as all said to no fix, obviously it will need to go back to Dell for a real fix!

Open BIOS by tapping F12 during boot and change the setting back to SATA.
IRQL Less or Not Equal error is usually a memory fault (either faulty RAM or faulty sockets on the board). Grab memtest and see what it reports.

    I have already tried this to no avail even before you gave me this as a try-so at least it shows I am on the right track. It powers up then powers down like 4-5 times (with nothing showing on the screen) and then just stays on with nothing on the screen. I just figured there was a reset like I have had to do with one of my other laptops that I had to pull the battery and hold down a key while I tried and power up, that worked on that laptop, just thought maybe there was this solution for the Alienware that was similar.

    Yes, resetting the BIOS by removing the battery is your only option left. But the problem you should take care is why you can't get in the BIOS, whatever the hd's setting - and this points to a totally different and unrelated problem, the memory is faulty .

Alienware m15x fan noise problem

Get a can of compressed air and give a good blast to open ports and cooling fans, this may resolve the issue, if not the fan will need to be replaced. I do recommend the computer be taken apart down the road for good cleaning.

Keep getting an error message irql not less or equal and system reboots. what do i do

IRQL errors are generally software/driver induced.
1st see if you can boot to the safe mode (F8 at boot) and get into windows.
If you can try a system restore to before the issue started.
If you can't get into windows, try Fn + power and run diagnostics on the system, you may have a bad hard drive.

irql not less or equal sounds like a graphics driver problem. All you needed to do was boot up in safe mode and remove the gfx driver and the OS would have rebooted with the default driver and then you could have reinstalled it
