My VAIO laptop was (VPCEJ2A9E) undergoing the normal window updates earlier (windows 10) but lost power during the update (due to a battery unable to hold any charge an a senitive power cable.
Now when I try to reboot I get a black screen only, I can hear the fan running and see the on light and charging light as well as the caps lock / number lock lights so I know it has power. It just doesnt seem to be booting the harddrive
I have tried pressing F2, F10 and other F keys to get the BIOS but again nothing
The model VPCEJ2A9E is a non-US model thus we have limited information about this model. Please make sure that the model of your laptop is compatible with Windows 10 operating system. If it's not and you upgraded the system then there will be no drivers that will support it. This will also limit the functionality of the device.
We highly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/ to assist you with this issue.
