RE: Bios A11 update for Inspiron 7520.

Jump to solution

There is a tiny difference of gaming for A11 rather than A10 BIOS.

I test in BF3(Auto, mostly mid + 4AA+4AF+1080p) and Skyrim(all high, 1080p,2x FXAA,2AF).

In BF3 the fps increases from 30-41 to 32-45.

In Skyrim the fps increases from 25-35 to 29-36

However, A11 is not perfect.when I am using an SSD rather than HDD.

When cold boot up(from shutdown not from restart), the computer will enter boot up page and shut down once, and i have to press power button again for second boot up in order to enter windows.

I am using Windows 8.1

here's the BIOS,but you should understand that there's risk to update BIOS

I'm using windows 10 pro. I have downloaded the bios file 7520A11.exe from dell's site.

I double clicked in the file cliked ok and the PC restarted. 

Then the first screen show a message like "Error: Invalid Firmware Image!!!".

Have you ever experienced something similar?

Hi,

the installer is made for windows 8 to be precise. Had some troubles here after upgrading the BIOS in 8.1. Got a replacement motherboard and whiped HDD with fresh windows 8 on it.

First upgraded it to the latest BIOS and then to windows 10. Works perfect. Try installing all the latest drivers from dell but dont forget to get the latest AMD and Intel grafics drivers after the ones from Dell..

Were You able to upgrade the BIOS to A11 version?

I'm asking cause I'm also using Win10 Pro on Inspiron 15R SE 7520 and have been facing problems with AMD HD 7730 drivers.

Currently I have to keep the Display adapter of AMD disabled otherwise the PC keeps on restarting with "thread stuck in device driver error".

The AMD driver version on my system is "15.200.1045.0" and a new version is available on drivers page but the installation of new Driver fails so I was thinking of Upgrading my BIOS as last resort.

I did the Bios update in win8 but this went fine.

For the display drivers, first get the latest display driver from the Intel website and install & reboot.

Then get the latest driver from AMD, the beta 16. something works fine. Install & reboot. Should work fine then.

@Carharoth , I upgraded My BIOS to Version A11

I am using Win10 Pro on Inspiron 15R SE 7520 .

Everything works fine.

BUT I still have been facing problems with AMD HD 7730 drivers.

Currently I have to keep the Display adapter of AMD disabled otherwise the PC keeps on restarting with "thread stuck in device driver error".

This problem was faced even b4 updating the BIOS version , so any one looking to Update their BIOS version can procedd it shouldn't be a problem.

Hey Vipro,

try and install the latest amd HD77xx drivers from the AMD support website.

The Dell drivers are very old.

support.amd.com/.../mobile

Begin with the 17.7.2 drivers. Then try to upgrade to 17.10.1 drivers.
