Sleep on T60 (1951-44U)

[p.c.27618349]

Hi all,

I have a plain T60 (1951-44U) but with 2.5 GB RAM and a 320 GB HDD.

My installation is iATKOS 5i updated via Apple all the way to version 10.5.7. I used:

PC EFI v9
dsmos
SMBIOS-EFI Air
Stock ACPI Modified
Disabler.kext
GMA950b
EFI String for Intel
Intel AHCI SATA
Laptop Battery
Intel Speedstep B
NTFS-3G
Intel PRO/100 VE

as my checked options in the installation.

My system can go to sleep just fine, with the sleep icon lighting up and all, but when it boots back up, it comes up with "Error 0192: Embedded Security Hardware Tamper Detected". If I hold the power button for 5 seconds to reboot and boot it back up, everything is fine albeit it's like I started up fresh without sleeping.

Any ideas on how to fix this?

Del AppleLPC.kext in /System/Library/Extenssions/
and Del AppleACPILPC.kext in /System/Library/Extenssions/AppleACPIPlatform.kext/Plugins
good bye

Didn't work. I think the issue may be BIOS-related because it occurs after the Thinkpad logo but before anything else.

This is not a bios problem, it is a recurring problem kext few months ago and corrected with the deletion of the two file "LPC" ... You load probably incompatible kext.

Can you, or anyone, tell me which kexts are conflicting? I personally don't see any that would potentially conflict except for the GMA950b and EFI String for Intel. Is that it?

I have yet to read of anyone that has sleep working correctly on a T60. Seems as though more progress has been made on the T61P. I know i can't get it to work on a T60.

I had played around with the PowerManagement.kext, replacing it with a different version downloaded from InsanelyMac. When I put in the new one, sleep worked!, but it no longer detected a battery. It was vice versa with the original.
