E6540 Owners Thread

I'm really sad to hear it. I had to do an awful lot of civilized yelling via email to get my swap done, and I was hoping it would become easier for later folks. The E6540 is just plain broken, Dell knows it, lies about it, and refuses to take ownership of the issue, as the current corporate slang puts it. A real crying shame.

 

I tried all the emails I could find listed, from the [email protected] one down through regional managers, and I never got any responses from anyone but basic support or later my "Executive Customer Support" rep, who actually misspoke or lied on at least one occasion. I doubt there are any magic bullet emails to help you escalate, you need to just grind through and refuse to give up or settle.

 

Ok thanks... but how do I flash via flash drive if it won't even bootup ?

 

Luckily I managed to get my case to someone quite senior that resolved the case with a 10 minute phone call.

Sounds like the faulty BIOS flash killed the machine. I think you'll need to call up Dell and get a tech out to replace the motherboard. Tried holding down Fn and booting the machine up - with any luck you will boot in to the on board diagnostics.

Thats my case I need to use dGPU for CAD application, but Iam not able to do it. Apps are still running on i4600 and performance is not good as could be. Is there any possibility to switch between i4600 and dGPU manually? On my Acer I can do it (see screenshot), but on Dell not.

 

Out of interest what CAD application are you using?

EDIT: I've got it working now; I had to change my power plan to balanced (left it on a power saving one when I was using it on low battery earlier, it's really quite aggressive in forcing things back to the Intel GPU). I suspect that using the 'high/ultra performance' power plans will tend towards using the dGPU.







Hopefully this helps.

 

Mainly Iam using VISI r20, dies assembly which I open are around 200MB - CATPart or STEP.

I tried all of your advices and no effect for Dell driver.

With AMD driver 14.3 beta seems to be working. Power management is set on High performance not Balance, visi.exe is set on High performance as well, but when I open some pages on the internet, screen is flickering and in several seconds NTB is completely frozen - means hard reset

 

I'm having black screen flickering issues with Firefox too, the driver profile is set to power saving (i.e. Intel GPU). I think it's having some problems switching between the Intel and AMD GPUs.

 

Wow. I am genuinely impressed. If you wouldn't mind comparing notes with me sometime, I'd love to know what you did that I didn't.

 

No problem. Will send a PM to you.
