Hi all
I saw that this maybe a rather common problem.
When i switch off or stand-by the laptop, it is not able to start just with the battery. It needs to be plugged, also for just a fraction of a second to the charger and then it is able to start just with the battery, which is generally reported to be almost 80% fully charged.
Battery was just replaced by sony (voluntary replacement scheme) so the problem persists under the two batteries but it's obviously unrelated to the battery.
Thanks for any support. Best, Fabio
