Running LCD BIST

[nina-9]

I'm going to sound very stupid now but...

A Dell technician has requested that I run the LCD BIST by "holding down the D button and the power button". I swear I've tried it about 40 times now but I can't get it to run.

If I briefly press both buttons down when the laptop is turned on, it hibernates. If I long-hold them both down then it turns off.

If I turn my laptop off, hold down D, press the power button and release them together (which is how I've seen someone else do it) then the laptop just turns on normally. If I hold it down for a bit longer, then it starts turning on and then turns off again.

I've also tried it with the Fn button instead of D, because when I Googled it some websites said to use that instead. No luck. I feel like I've tried pressing these two buttons every freakin way possible but it won't run!

Any advice?

It's an Alienware M15X (and it's about to go out the nearest window).

If you can see the screen, try turn on and then press F12 for the boot selection menu and then pick diagnostics.

Not sure if this works, but it's possible that it might help.

Yeah, I can run the startup diagnostics fine (and it passes the LCD tests in there), but it looks like the LCD BIST is different. There's a video on YT:
LCD BIST.MOV - YouTube
Of some guy with an M17x running it and it flashes the screen different colours rather than having that multicoloured screen that moves (plus, the Dell techie has already asked me to do the F12 diagnostics before the LCD BIST).

I just don't know why my laptop won't run it. I'm doing the exact same as the guy in that video and my laptop just turns on normally.

Thanks. Well at least I know it isn't just me being really stupid. :S I guess I'll email the techie back and tell them that it doesn't work.

Here's a General Video TS Article, they mention BIST and how to use it, hope it helps.

Thanks. Turns out I didn't actually need to run it after all, because the diagnostics on their own proved that my LCD was running fine. The technician doesn't really seem to know what to do, lol.
