Is that a dual core CPU or hyperthreaded single core.

Ok it's got two cores. Reason I asked was disabling say a 2 ghz single
core HT CPU can acutally boost performance. When in HT mode the RAM and
the CPU process at 1 ghz.

After the "cpu disabled trick" worked well for hours, with laptop
running and restarting with it PSU, I had no more luck. The day after
it didn't start as before. Tried the trick again, I even disabled both
cpus in devmgmt but no luck. Used an hardware monitoring program to
investigate situation but nothing helps, only curious thing is that
trying to access ACPI temperature values the pc suddenly powered down.

Even when all seems running weel on battery, or "fake battery" with
12V PSU, the pc freezes at a point in some conditions that I still
have to determine, but to me this shows it's an hardware fault.
When running on normal PSU in Windows 7 I tried to change the options
for the power/tilt/sleep buttons and the pc freezed, and that was when
it didn't worked any more that way. Power buttons options can be
changed without problem running on battery.
On battery the pc can run for hours, but it seems that stressing it a
bit and leaving it alone leads to a freeze or a sudden power down,
maybe when the power management decides to do something, something
that I cannot know as I simply find the pc hanging on or completely
powered off.

I must check the motherboard, but except for ONE capacitor in the
power section that is 3 or 4 mm big (and still smd) all others are
small SMD, and you can just identify them by being marked Cnumber as
I think all resistors are Rnumber.

The problem is I need to find a day with plenty of time, as to test
those capacitors needs to unweld them with hot air check and solder
them again, and they are soooo small... there are smd three-legs
transistor components too, but I do not think I would be able to check
them.

Maybe I should start with the few fuses and resistors as they can be
checked in place to see if they are opened, at least.
