Dell Latitude E6540 bios needed

Re: Dell Latitude E6540 bios nedded

Just to update on my issue, I no longer need help. I used and flashed BIOS from post #24 and although it was for another motherboard model, it worked flawlessly and everything is fixed, its fast, sleep works and its also newest BIOS version as a bonus. Big thanks hardware1!

Re: Dell Latitude E6540 bios nedded

Sorry, fixing my last incomplete post.

Laptop model: Dell Latitude E6540 with i5-4310M, no dedicated GPU
Motherboard model: LA-9414P Rev1.0(A00)
Service tag: 9824S32

Dump of both 64 and 32 chips is in the attachment.

Problem is no video output, not in built in display nor in external through VGA / DP. Only black screen. Fan is working. Keyboard backlight is working.


On the sidenote, I tried reflashing some bioses that I found online for this specific board, but boot time is 25 seconds until Dell logo and 45 seconds until Dell logo if secure boot is enabled. For both uefi/legacy. Also sleep is not working and will restart computer instead. But laptop works fine overall, wont shutdown, tested for few hours, so it's at least usable. I even tried updating official BIOS update from Dell website through their .exe file, but it doesn't have any effect and laptop just restarts.

So I would be glad if the BIOS I had before is fixable, but I will make my peace if its not and use the one I found.

Re: Dell e6540 vala1 - corupted bios ?

Good morning. I have a Dell e6540 vala1 la-9412P. The laptop turned on with a black screen. After resetting, the bios turns on for a few seconds and then turns off. Would any kind soul take a look at the bios/ec files? I tried various solutions from the forum but without any positive results

Re: Dell Latitude E6540 bios nedded

Do you have by any chance LA-9414P working BIOS for both chips? Black screen, fan is spinning and CPU is hot. No external or internal screen works, no error sound. Only error sequence on power LEDs when there is no RAM inserted.

Re: Dell Latitude E6540 bios nedded

Unfortunately, it does not work, it does not pass POST SEQUENCE, LED lights up and goes out.

If you program back your Original Bios the device works or not?

Re: Dell Latitude E6540 bios nedded

I have problem with LA-9413P Rev 1.0 A00, my old CPU i7-4800 was broken, I replaced it with I5 4300M. Laptop works fine but shuts down after 30 minutes. I've tried Clear ME by FIT but they don't half turn on.

Here's you Clean Bios, try it.
