Acer 5742-374G50Mnkk - ps2 keyboard no working after sleep

[marktj]

Hello guys! I am a new entry

As per title, I have got this laptop (specs below) which has almost everything working but after sleep I can't type the password because the internal keyboard doesn't work. Also I would like to patch my dsdt to make it perfect, is there any way to check if all the system, power management, hpet and stuff like that, are working properly?

Hello guys! I am a new entry

As per title, I have got this laptop (specs below) which has almost everything working but after sleep I can't type the password because the internal keyboard doesn't work.

What trackpad does this laptop have? What PS2 drivers are you using?

Hello RehabMan!

Thanks for the reply, I am using the latest voodooPS2controller (prefpane from another source), the trackpad is a Synaptic and it's working very well, nice smooth and multitouch, also after awake from sleep..

Hello RehabMan!

Thanks for the reply, I am using the latest voodooPS2controller (prefpane from another source), the trackpad is a Synaptic and it's working very well, nice smooth and multitouch, also after awake from sleep..

Are you using mine or some other? There are many, many branches of VoodooPS2Controller? My version happens to be one of the more polished for Synaptics.

Mine is here: https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller

If mine, you might try modifying WakeDelay in the Info.plist for VoodooPS2Controller.kext (/S/L/E/VoodooPS2Controller.kext/Contents/Info.plist)

It is Default 10ms (0 for HP ProBook). Try something larger... say 1000ms. This is the amount of time the driver waits after wake before manipulating the KBC (i8042 keyboard/mouse controller). Maybe some devices need longer.

If you're not using mine, maybe try it (and still play with values of WakeDelay).

Usual cautions with modifying kexts. Always repair permissions & rebuild cache before rebooting.

If you're able to build things (xcode), you could also build 'ioio'... you will find it on my github repos here: https://github.com/RehabMan/OS-X-ioio. It is a little command line program that allows you to tweak driver properties from the command line. In this case you could try different WakeDelay before sleep:

# 1.0 second
ioio -s ApplePS2Controller WakeDelay 1000
# 0.5 second
ioio -s ApplePS2Controller WakeDelay 500

With ioio, you can play with the various values for the case that a larger value works and you want to narrow it down to the smallest value that gives reliable results.

FYI: The trackpad driver already waits 1000ms after wake before manipulating the trackpad (as specified by Synaptics spec). That delay happens after the WakeDelay in VoodooPS2Controller (trackpad wake is called by controller wake).

I'm using yours, the 1.8.7, I tried 500/1000/1400, same problem, trackpad ok but keyboard no way! Also this time my screen was switched off ..weird! I patched the _WAK on my dsdt!

Does your computer work after wake with a USB keyboard, no VoodooPS2 driver loaded...???

 

[marktj]

Unfortunately I can't try any USB keyboard, I am in a college in UK.. my usb mouse is working
I attached a short video..



By the way, my laptop despite the 5742 series is quite different from the popular model with nvidia card, this thread can be useful to other users have my same model, if I fix the sleep problem I can say to have a mac

See if you can find a USB keyboard to borrow...

And does clicking Cancel on the login screen after wake work (go back to sleep)? You could also disable the password lock to see more about the state of the laptop after sleep (is the clock updating?, can you click on things?, etc.)

Ok, I removed the password after sleep, basically all the system freezes when I wake it up, the only thing that works is the mouse.. I can see all my windows and apps opened but I can't interact.. usb keyboard doesn't work! I think there is something to patch on my dsdt..

this is the last message from the console if I put in sleep from the power button and not from the lid, in this case the system sleep and wake up immediately

Is the system completely frozen or is just the input system frozen. How to tell: does the clock update with each minute?
