vaio z laptop freeze with intel ssd when power source is changed from battery to AC power

[idata]

I am using a Vaio Laptop Z690. it came with 160gb hdd and i swapped it with 160 G2 intel ssd.

the lockup/ freeze only happens when the laptop is used on battery for over 10~15mins and reconnected to AC.

I tried three different OS's Windows 7, Windows server 2008 R2, windows vista. Same issues.

To make sure it is not the drivers installed after the fresh OS installation, I tried the changing power source with and without the necessary drivers.

It happened when necessary drivers are installed and it still happened when no driver is installed.. right after the first boot of the OS.

Morevore, to verify it is not related to power options, i tried the experiment with performance and balanced option.

i turned C-states off in the BIOS and reset the bios everytime with a fresh os installation.

It does not happen all the time but may be 3 or 4 out of 10 times... and it doesn't happen when the duration of use on the batter is short or instant.

I called technical support to arrange a repair on this specific matter or issue.

B/C it might avoid the manufacturer warranty, I swapped the hdd back. Since then I am trying to record this freezing issue using my iphone...

I got a couple videos that show it is frozen with SSD. However, I did the same experiment for 5 times now... and it doesn't freeze with HDD.

anys guesses for what could have caused this or why this keeps happening?

@ NandFlashGuy

Can you please confirm if any of the settings below could cause a conflict with a ssd that would results in freezing/ bsod?

ACPI 2.0 Support – Enabled or disabled?

ACPI APIC Support – Enabled or disabled?

S0 Working – Enabled or disabled?

Processor states

The CPU power states C0-C3 are defined as follows:

C0 is the operating state.

C1 (often known as Halt) is a state where the processor is not executing instructions, but can return to an executing state essentially instantaneously. Some processors, such as the Pentium 4, also support an Enhanced C1 state (C1E) for lower power consumption, all processors must support this power state.

C2 (often known as Stop-Clock) is a state where the processor maintains all software-visible state, but may take longer to wake up, this processor state is optionally supported by the system.

C3 (often known as Sleep) is a state where the processor does not need to keep its cache coherent, but maintains other state. Some processors have variations on the C3 state (Deep Sleep, Deeper Sleep, etc.) that differ in how long it takes to wake the processor. This processor state is optionally supported by the system.

Here's a link to Tom's Hardware about BIOS power settings:

http://www.tomshardware.com/reviews/bios-beginners,1126-8.html http://www.tomshardware.com/reviews/bios-beginners,1126-8.html

The first paragraph warns about using BIOS and Windows for power management.

I haven't played around with BIOS settings myself. But I haven't had any problems using any of these power states with either a G1 or G2 X25-M with my Lenovo ThinkPad. Keep in mind that Windows XP (and not the BIOS) is controlling the settings in my case.
