I suspect 2 possible reasons for the malfunctioning.
1) A bios update that I did after which I notice the screen goes blank for a few seconds a couple of times at start up
2) I use the Registry first aid agent. This could have done something to settings. I tried to go in for a restore point from the registry editor, but it gives only a restore point that is later than the bios update date.
I want to do a restore to factory settings. I tried to find how to do this from
http://uk.computers.toshiba-europe.com/innovation/generic/SUPPORT_PORTAL/
The page lets you download a note book auto detection tool which is unable to detect, neither is it able to find the serial number Y8144090W
However the tempro alert on the note reports the number correctly.
I tried the utilities installed under programs > Toshiba > utilities > HWsetup and restored HW settings to default. It did not help.
Can you please let me know where I can find the resore to factory settings is. It is not in the user manual.
