[REQUEST] Dell Inspiron 15R SE 7520 BIOS Unlock

[tarzan]

success 1: im disabled pci express port 0 aspm function ( total like 8 slot - not pci express graphics slot )
realtek gigabit ethernet sometimes startup ip can not take or when cable change ip can not take problem like fixed. when i finished test i will try half of aspm. its not too effective on all powermanagement. but effect ethernet connection stability.

im from turkey

who bricked their inspiron. if machine opening and if not get display output. i can say button combination for load bios defaults.

if machine opening without display output. he can write buttons blindly. but only one button press combination from startup.

What is the button combination friend?
Another friend bricked his notebook changing fan settings, he gets black screen with only fan and lights

this is possible if machine not totaly locked. only not giving data to monitor and not opening with error.

press function button open machine. 1-2 sec later start tap F2 repeatly. do this 5-10 sec and release button.

press 8 times "->" right arrow button
press 3 times down arrow button
press 2 times ENTER button
press 3 times up arrow button
press 2 times ENTER button

its mean u join bios
u going to load optimal defaults
u enabled
save and exit.

if machine not locked totaly
and bios is unlocked bios here. because menu number is different in original bios.

oh, this will not work as he is not getting screen but I think he is not getting BIOS to load properly too :/

[tarzan]

i writed "succes 1: realtek gbe ethernet problems fixed with disabling aspm" but not %100. sometimes when boot or unlplug/plug cannot take ip problem not totaly fixed. but now better. im testing other possibilities.

[felipejfc]

I'm more interested in graphics experiments, I really wanted to turn off IGD or making PEG really works as my first diaply :/

[tarzan]

u right. single gpu mode more important.

lescatlabs unifl driver maker know "muxless fixed graphics" mode. i will try contact from his forum. and send snapshot of unlocked bios menus. he is know this situation.

[felipejfc]

I think that the problem is that the display is attached only to IGD and IGD passes information to PEG, so that's the cause that we can't disable IGD, isn't it right? also, maybe disabling IGD may be disabling the whole processor in my computer as when I try to turn it on with the option turned on, I get not screen or fans, just 5 beeps.

inspiron 7520 totaly px 5 design. there is no diret connection between lvds and dgpu(peg card). like last nvidia optimus.

but may be its run virtualy single screen card. muxless fixed mod. intel screen card will only run like bridge but not totaly activated. fixed muxless mode mean like it. but there is no compatible driver for "fixed muxless mod"

disabling igc disabling all processor is may be intel rule. because intel force to use their igpu to notebook brands. else because lots of brand will not use this.

there is fixed muxless mod samples in some sony vaio notebooks.

im bricked notebook. totaly opened case and resetted cmos.

you released inspiron disassamble picture. thanks for it they are realy valuable. but i must add. there is 2 more plug is not pictures for open case. 2 shining plug(not black) in empy dvd rw. i released them....

and who opening this machine very carefuly for ide cable like connections. wrong force without unplug can easly break cables....

im removed battery. connected battery + - points both. replug battery.

after there is jp1 csv1 like writings. im tried connect lots of naked connection points there. because real cmos clear jumper near the battery. there is some writing but clear jumper is secret.

dont touch dmi aspm settings. someone slowing machine someone blocking startup.

im setting dvmt pre allocated size to 512 mb its good effect. ( but first boot machine closing dont be in horror. press function button again )
