Hi,

 

Try the following.

 

Shutdown the notebook.

 

Unplug the AC Adapter and then remove the battery.  Hold down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.

 

Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.

 

Regards,

Hi,

 

Can you post back with the full Model No. and Product No. of your 15t series notebook - you can usually get this by holding down the fn key and pressing esc, otherwise see Here for a guide on locating this information.
