Windows 7: Windows 7 - Dell Laptop: Switchable Graphics using i7 & AMD Radeon

Hi to all dear members

I have read this topic : (all of 29 pages ! )

Acer Laptop: Switchable Graphics using i7 & AMD Radeon

I have the same problem too

But my laptop is dell - inspiron 5520

My system specification is :

=====================
CPU :
Intel(R) Core(TM) i7-3612QM CPU @ 2.10GHz --- Ivy Bridge

RAM :
8.00 GB Dual-Channel DDR3

Graphics :
AMD Radeon HD 7670M
Intel(R) HD Graphics 4000

BIOS :
Brand Dell Inc.
Version A07
Date 05/17/2012
===========================

But the big problem is there is no Video Configuration in my bios

and there is no updated bios software in dell site :



Drivers and Downloads | Dell [United States]


From the above topice about aser , I have noticed that the only way to solve the

problem is using the modded bios. if i am wrong , let me know

I searched this site but there is no modded bios available to my laptop

Bios Mods Tools; - [http://www.bios-mods.com/BIOS]

please help me.

thanks alot.

From what I can tell from the Dell documentation, you can only use one or the other and if the optional video, such as you have, is installed that is the default.

The Dell BIOS is protected and any attempt to modify the Dell BIOS will most likely cause it to Corrupt. There is no recovery from a corrupted BIOS on a Dell, the ONLY option is to replace the motherboard.

I agree with fireberd.

I am amazed at Popeye and the gang over on the Acer thread with their willingness to play with modded BIOS. But it works and they seem to have found a solution. But the key is that someone with mad programming skills created that modded BIOS for that one system. Unless you found the same thing I would steer clear.

What you can do is complain loudly to Dell and on every public forum you can find. They need to make their machines functional. It is unacceptable to have dual graphics but with no way to switch to whichever graphic adapter you, the owner, want to use at any given time.

Looking at the Dell specs for this model (and several other similar models), it looks like they apparently use the same motherboard on all the related models, a basic model with just the Intel graphics and upgraded models with a separate video card. On the models with a separate video card that is made the default in those models.

What the manufacturers do is use a "switchable graphics" method.
For "normal use" and anytime you are on battery power the system defaults to the intel graphics.
Only when the system determines that you are entering a "high graphics" mode does the system switch to the dedicated graphics adapter.

What gamers are complaining about is that the system does not make the switch when playing a game that could benefit from it. They want a manual method to use the higher performing adapter right off. They are willing to take serious risks to do so too.

thanks alot for your answers

finally i could not find any way to solve my problem

i should wait for someone who can mod this bios.

thanks alot.

best regards.

be fresh.

I have the same problem. And I posted another thread before reading this one:

Switchable Graphics in DELL Inspiron 5520 Not Working

I also downloaded the file they did, and I don't know if I can/should use it or not. I updated my BIOS from A05 to A07, and it was really easy. I've read how to update/install a BIOS from here:

Bios Mods -The Best BIOS Update and Modification Source: BIOS Update

It's just that I don't know what BIOS will work with my laptop. If anyone can tell me whether I can install the BIOS mentioned in the other thread or not, I will probably do so.

Well I have the same problem but with Sony Vaio Series E - SVE14A2.

Specifications:
- Intel Core i5-3210M CPU @ 2.50GHz
- 6,00 GB Duplo-Channel DDR3 @ 798MHz (11-11-11-28)
- AMD Radeon HD 7570M/HD 7670M Graphics
Intel HD Graphics 4000
-750GB

The computer has 2 Graphic software but none of them has switchable mode.

Anyone can help»?
