My notebook has some trouble:
When the notebook is connected to the AC Adaptor, it starts to boot but automatically shutdown after the 'Sony' logo. It can't be reboot afterward for a short period of time (usually 5-10 minutes).
However, there is no problem when it is not connected to the AC Adaptor. It works well by battery supply.
Is it the problem due to AC Adaptor? Or due to the mother board?
** The battery can be recharged by the AC Adaptor when the notebook is SHUTOFF...
