need details about cable

is only cable replacement or  with screen
also form where you got gray cable
also when you had gone  to dell support what had you said to them

Changed throughout the screen. The only thing different is that I saw the handle of the new screen was gray. But do not open the screen to see the brand. I suggest that you contact Dell and ask to replace the LCD, but make a mark on the cable before to see if exchanged.

[Mohamed Khairy]

you did complete screen replacement why ? was it broken ?

for whom have freezes can try to see the color of  cable and search on dell store for cable with gray cable and  test

I got a Dell Vostro and I'm working on screen backlight. How do you manage to make it work ?
I think it can be a good way to investigate on it
Thanks !

[LinK14]

I mean the screen brightness. How do you manage to make it work ?
I don't want to use your VoodooPS2Controller as the Vostro is not the same. But I want to know where do you find the "patch" for it, or if there is a way to patch the kext by myself.

[Mohamed Khairy]

first check if brightness works on system pref --> displays

then you can use the linked voodoops2controller  will work for you

which kext you use for  your touchpad .. voodoops2mouse ?

for source check here

Go to system preferences=>keyboard=>keyboard shortcuts=>display and assign keys F4 and F5 for brightness control

I did change the screen that could not solve the problem any other way. I replaced the processor, motherboard, but only was perfect when I changed the display.

we need DropSSDT=Yes on boot.plist of getting turbo work !

For me it did not work, if I put the DropSSDT=Yes Geekbench is above 1000. Here with DropSSDT=No

No. But I believe that this can trigger the guarantee out of free.

[Mohamed Khairy]

if benchmark increased with dropssdt this means that turbo works

to me with out turbo  nearly result 4000 with turbo jumbo to 6000

I use a kext with a prefpane for my trackpad. I found that on osx86.net. BTW, did 3-fingers gestures working on the Inspiron ?
Finally, I used that for brightness :
http://www.insanelym...howtopic=236835
Just modified the DSDT with the two methods and it's OK. I'm just not sure that I have all luminosity levels, but that's good for me.

Now then, is there a way that the brightness is memorised through shutdown and reboot ? Because it's set to maximum each time the PC reboot.

[Mohamed Khairy]

you don't need this line on dsdt
Name (_HID, EisaId ("LCD1234")).
if you don't use generic brightness kext

just          Device (PNLF)
needed also this is basic patch for laptops

about touchpad our notebook only works with ps2mouse next no advanced trackpad next so no multitouch function on it just single touch

brightness level not saved on any os  
if you want to save custom brightness you need to search for program that save this setting and load it every time you load system

i don t use that flag i still get 9000+ in 64bit mode geekbench marks scores    i have 2630qm.. i ll try using this flag and lemme see my scores

hi again
i made SSDT.aml for my  cpu
and you will need to make one for you to generate many pstates that will make your cpu not to  jump in use

so this will make your cpu less power consumation

you refer here to see how to do it
i can't do ssdt for every user but every one can share him one

http://www.insanelym...c=258611&st=460

and here is my  ssdt table generate 22 pstate from 8 to 29 turbo  
if your  cpu is 2.3 and it is turbo 2.9 you can use it directly
and if your cpu isn't like that you need to edit it

 SSDT.aml.zip   735bytes   80 downloads

Great!
I knew it! But I'm not familiar in dsdt editing.
I will try when I'm back to my hack.

Need for SSDT drop or not?

it is easy just understand what do you do
you need to DropSSDT

here is a simple idea of this thing
first to calculate your needed  pstates
my cpu min frequency is 800 and highest turbo 2900
so multi per is 8 --> 29
now calculate it  /   29-8 =21 --> +1=22 pstates

now my pstates is 22 mean that i need 22 one like this


Package (0x06)
{
0x0B54,
0x88B8,
0x6E,
0x0A,
0x83,
Zero
},

but with different value according to freq

you will do your edit under this two  arry

Name (SPSS, Package (0x16)

Name (_PSS, Package (0x16)


0x16 means 22 on dec
use calculator for this
and below every one is 22 Pstate

and after you calculate  your number
now you will apply your cpu setting
nearly every intel cpu on notebook begin with 800 hz so it will be easy to use my ssdt and do minimal ssdt edit

will give example about core i3 with 2.3 mhz
pstates needed 23-8= 15 --> +1 = 16

so what will i do on ssdt will delete 6 pstates and renumbering only

will delete  first 6 state under every array as i told before
so  
Name (SPSS, Package (0x10)        --> 10 means 16 state

will begin with

Package (0x06)
{
0x08FC,                  --> is 2300 on on dec
0x88B8,
0x6E,
0x0A,
0x0683,                  --> 06 will be 00 as it will be the first state you will renumber all state from zero to 0f
0x06                     --> as above
},

and
Name (_PSS, Package (0x10)
will begin with


Package (0x06)
{
0x08FC,
0x88B8,
0x0A,
0x0A,
0x1700,     --> 17 mean 23 on dec means multi per of freq  no need to edit
0x1700      --> as above
},


etc if your top freq is 3000 so you will have 23 state you will need to add new state on start of state with 3000 freq

sorry iam so sick and can't go more on explanation  hope you got the idea
