L502X modded bioses download (GPU voltages and more!)

[ComputerStud]

A9 bios is shyt on my system. Constant fan on and off.

A7 bios with tweaks does not suffer the on/off fan cycling.

Thanks for the A7 bios and the volt mod.

GPU doesn't break the 80C temp whereas before it was reaching 96C (near boiling temp).
Also MSI Afterburner overclock to 780/900 stable at 0.85v.

You are indeed the Capitan and rep.

thanks for your reply brother. the problem is sloved. now adays its possible to install mac os even on MBR partitioned drive. I have successfully installed the latest Mac OS X Lion 10.7.2. Now i do dual boot with windows 7. its great. My XPS is awesome now. just leaves only one more thing to be desired, to disable the optimus technology. so that Nvidia GPU is used all the time. which would be great. is it possible through bios modding ?

as far I know that is not posible , at least on the XPS 15.

because the intel gpu is the one wich is directly conected to the laptop screen and minidisplay output, the nvidia just have the hdmi output and help the intel card sometimes

also, in the intel card, when it need to render some advanced video applications, it request nvidia gpu to render it, and intel gpu just show the finished images outputed by nvidia card.

so, as you can see, the nvidia card just act like a auxiliary card.

this have some advantages like the battery time while disabling the nvidia card when it isnt needed, but also disvantages like having to set up every app to make sure it uses the nvidia card through the nvidia control panel.

it is a bit annoying at the first system configuration.

this is like a mid point between power saving and performance.

ok so we cannot disable it. Its just that sometimes windows aero runs slowly because it is powered by intel hd 3000. if windows aero was powered by nvidia gpu it would be superb in dell xps 15 with normal HD screen.

xps 15 Full HD screens are powered by nvidia GPU and so does the windows aero

@ComputerStud

oh, srry, didnt noticed about your post, we posted almost at the same time.

well, thank you a lot for the feedback.

yes, some users posted the official A09 bios do strange things with the fan specially in battery mode, so the tweaked A07 should help in this case

what card and modded bios settings are you using?

(to add your nickname to the first post as tester )

@eggy_brahma

yep, as far I know there are no way to disable it.

however you may find a workarround for the windows aero thing.

I made a script to enable/disable windows aero service with one click

just create a normal .txt file, paste following and rename it to *.bat

for example aero_toggle.bat

@echo off
title KASAR Windows Aero script
set aero_file=ksr_aero.txt
color 17
echo.
echo #######################
echo ## KASAR Aero Script ##
echo #######################
echo.
echo.
echo.
if not exist "%aero_file%" goto file_fail else (goto read)

:read
title KASAR reading file...
call :read_file<%aero_file%
goto show_info

:read_file
set /p aero_status=>nul
goto :eof



:show_info
rem echo current aero is: [ %aero_status% ]
echo.


if /i "%aero_status%"=="disabled" goto aero_on
if not "%aero_status%"=="disabled" goto aero_off



:aero_on
echo Enabling aero ...
title KASAR Enabling aero ...
net start uxsms >nul
set aero_status=enabled
goto write_file


:aero_off
echo Disabling aero ...
title KASAR Disabling aero ...
net stop uxsms >nul
set aero_status=disabled
goto write_file

:file_fail
color 47
echo.
echo the file %aero_file% does not exist ,creating ...
set aero_status=enabled
title KASAR creating file ....
goto :write_file

:write_file
echo %aero_status%>%aero_file%
echo.
echo.
title KASAR TOOL - Aero %aero_status%
color 27
echo aero is: [ %aero_status% ]
echo.
exit

I used it to save battery time and make fullhd playback more smooth with the intel graphics.

ussage is quite simple, just double click it to toggle on/off the aero.
note: sometimes you may have to run it twice when running it first time after starting the system

[eggy_brahma]

ok thanks. but i am confused about it. because when we set the Power Plan to Power Saver mode the windows aero automatically turns off. so is it same or different with your settings ???

[capitankasar]

no, you are right, the power saver mode automatically disables aero when in battery mode.

however this simple script allow to disable aero also in another plans, even plugged into the AC power.

I also use it a lot as a a pre optimization before going into games : )

[eggy_brahma]

oh i get it. thanks, will try it


yup works great

Capitankasar hablas español?

i found that the MD5 checksum for the A09 bios

3C8EA4113AF36830E173B48E1A359D71

dosent match with the one that i dowload =S

///english///

since you posted the same post on two diferent topics I will reply it here:

yes, I talk spanish ^_^

the md5 checksum and .rar file I uploaded are fine.

the problem is that the md5 checksum I posted is applied directly to the L502X_A09_540m_83_85.rar file, and the md5 checksum you calculated is the one from the FLASH_the_modded_bios.bat file

///español///

como has posteado el mismo mensaje en dos temas diferentes te contestare aquí:

si, hablo español ^_^

el checksum md5 y el archivo .rar que he subido estan bien.

el problema es que el checksum md5 que he posteado esta directamente aplicado al archivo L502X_A09_540m_83_85.rar, y el checksum md5 que tu has calculado es el del archivo FLASH_the_modded_bios.bat

jajaja ok que pena. voy a probar esta bios undervolt para ver si me soluciona el problema que tengo con algunos juegos que se congelan.

Por otro lado aprovecho y te pregunto si al tener undervolt no afecta en lo mas minimo mi tasa de FPS? osea si juego bt3 a 30 fps voy a seguir jugandolo a 30 fps o podria bajar un poco el rendimiento. ya se que esto lo explicas en tu post, pero quiero estar muy seguro.

Muchas gracias por hacer este trabajo y compratirlo.
