Latitude E6540 No graphic display after A08 BIOS update
Anyone having this issue? E6540 Windows 8.1 x64. I've been using A05 BIOS without a problem. Installed most current AMD and Intel Graphics Drivers. Still no Issue whatsoever. I Flashed to A08 BIOS and lost all Graphics, blank screen. Had to Flash back down to A05 using DOS boot flash disc. Display resumed fine. Next, I uninstalled both Intel and AMD current drivers. Proceeded to Flash back up to A08. System Booted fine with graphics. I then installed the Intel drivers. Rebooted and system remained fine with graphics. Then I installed the AMD drivers and CCC. Rebooted, graphics came up, however I receive an error message stating the AMD drivers are not functioning properly and CCC will not load at all. I was forced to Flash back down to A05. Everything works ok. There appears to be a conflict between A08 and AMD drivers and CCC. I had a similar issue when A07 was released. A08 seems no better... Is anyone aware of a fix for this issue. This PC was very expensive, problems like this are time consuming and hurt productivity. Not to mention Dell's reputation. Any replies are greatly appreciated!

Both AMD and Intel drivers were downloaded from the Dell site specifically for the E6540. For Windows 8.1 64 bit. As I mentioned, we tried both methods. 1st attempt, installed the latest video drivers, then flashed to A08. Total blank screen. 2nd attempt, removed all video drivers, flashed A08. Had graphics, but I receive an error message stating the AMD drivers are not functioning properly and CCC will not load at all. Had to flash back to A05. Very frustrating as I had this issue with A07.. Thought this was corrected in the release of A08. Thank YouAnthony001

Hi Anthony,
Sorry about the delayed reply. I would like to know if you have tried updating BIOS version to A08 on Windows 7 as we need to check if there are any compatibility issues. Please let us know if this was tried and if it is possible to try if not yet done.

Hello Arjun, As our previous postings state, We've been using Windows 8.1 x64. Clean install after purchase. Virtually no other software installed. All MS and Dell software is up to date based upon Windows 8.1 selection on Dell's site for our Tag number. So unfortunately, we're unable to test A08 on Windows 7. Thanks!DELL-Arjun BV

Hi Anthony,
In that case the problem may seem to be a compatibility issue with the BIOS version and the video driver which needs to be escalated to our product group team to check this and it will take some time. Until the next update I request you to use A05 BIOS to keep it working so this can be sorted out with the next release of BIOS.
Hi Arjun!
Yes the correct answer is to use A05.
But the problem (and the shame) is that I warned in January on this forum when A07 appeared with the similar problem. See here:

Hi Anthony,
We are sorry about this concern. Even we are surprised as to why this issue is occurring on your laptop. However, I would like to know if you have updated the video drivers from our website or AMD/Intel websites.
If you have updated drivers from their websites then I kindly request you to uninstall the driver and update the driver from our support website.
And update BIOS version once and let me know id it worked so we can check further.
