Trackpad not being detected by Windows 7

really? it could be outdated drivers, to be honest here, however its kinda rare for that to be the issue

been looking into dsdt editing, however that shit be confusing and like theres very little people who know that shit on the windows side so im kinda stuck lmfao

i did manage to apply my own table but editing it properly is another story lol

how?! i kinda suck at this reverse engineer modding and i cant even find appropriate software, if you at least told me how to apply your own table (what software, etc.) that would be really helpful

you need to download iasl.exe and acpidump.exe from here

now open cmd as adminand go to ur working directory, and i highly recommend not doing it on the desktop for this step as itll make a mess

run acpidump -b

youll have a bunch of files including dsdt.dat

now you can move dsdt.dat & iasl to ur desktop or somewhere else if you want to

run iasl -d dsdt.dat, this should produce dsdt.dsl which you can open in any text editor and itll be readable and you can edit it just fine

however it will be pretty rough to read and edit so good luck with that, but once you’ve made the mods you wanted, compile it with iasl -tc dsdt.dsl

will produce a .hex and .aml file, however you want the .aml one

at this state go into windows 7 if u werent already on that, and youll need asl.exe tool from microsoft which is like IMPOSSIBLY hard to find so ill go on my laptop in a moment to send it to you because i dont want you to go through the hell i had to go through lol

move it to where dsdt.aml is, cd to there, and run in an admin cmd: asl /loadtable dsdt.aml

make sure testsigning is on in bcd (bcdedit /set testsigning on) and then reboot and it should apply your modded dsdt

good luck!

asl.zip (94.1 KB)

btw as a summary:

acpidump - b > dsdt.dat

iasl -d dsdt.dat > dsdt.dsl

(mod dsdt.dsl like you want to)

iasl -tc dsdt.dsl > dsdt.aml

(in windows 7) asl /loadtable dsdt.aml > loads table

bcdedit /set testsigning on > required for windows 7 to load ur custom table

also im noticing now that i may have explained it in a kind of confusing way, so if you’re confused about something and have any questions, obviously feel free to ask lol
