Just troubleshoot one 4820TG, somehow it cannot switch to Intel. Always in ATi. Clicked the power-saving GPU, nothing happen.
So I try run the registry to restore the checkbox for auto switching,
Restart to BIOS ,
Change Switchable to Discrete,
Then boot into Windows,
Waited it to install the driver,
Then restart again to BIOS,
Change back to Switchable.
Boot into Windows and now the switching works.
Oh well, at least its fixed

Yesterday I got Windows Update, after update asking for restart, so I restart it.
when boot up, it take very damn long time at "Starting Windows".

I wonder new update have some bug on 4820TG...

Take a look, Now 4820TG can use SP1 update, its ok?
[attachmentid=2485300]
*some update make very slow boot up, I try use system restore, its normal, do I need to defrag the disk?

oh well, I think defrag use Live CD, so can defrag fully without any file used.
but I use system restore, it normal = = why eh?

you also got SP1 update?

I defrag, restart, no hope T_T still take so many minute to boot up, what happen now? do I format the OS? or Restore back?
