The circular motion Is done by using a finger and scrolling depressing the keys on the keyboard in a circular motion in a roughly 10cm diameter clock wise and anti clockwise. When I press the on button the green light comes on but but nothing else happens which what I call hangs or wont move on ( screen is blank as if off ).Do the motion then the screen will come to life and the first part of loading will happen. Then it will hang again until I do the motion and so on until I get into my profile. Now i can get into what sony site says is the BIOS by pressing F2. Its called Aptio Setup Utility Version 1.23.1109. Its been a while since ive been in the BIOS of a pc but it looks like what I remember it to look like. It has 5 menus across the top, Main, Advanced, Security, Boot, Exit in that order. I cant see any listing for SATA or AHCI that you say to change to. On the main screen The first 8 entries are greyed out unchangeable, but the last 2 System Date and System Time are changeable. The first 8 are BIOS Version: R2032Y2, Machine Name: VGN-AW31XY-Q, Serial Number, UUID, System Memory: 8192MB, HDD 1: 64GB, HDD 2: None, HDD 3: 64GB.
Advanced menu has 2 options, Intel (R) Vitualization Technology: can be enabled or disabled and is set to disabled, RAID Configuration: can be hide or show and is set to hide.
Security menu has 6 options, Machine Password: Clear, Usser Password: Clear, Set Machine Password: ( Press Enter ), Set User Password: Press Enter ), Password When Power On: ( Disabled ), Clear Fingerprint Data. Apart from clear fingerprint data and set machine password the others are greyed out.
Boot menu has 5 options under 2 headings. The 1st is Boot Configuration 2 options, External Device Boot: set to disabled, Network Boot: set to disabled. The 2nd is Boot Priority 3 options, which lets me set priority which currently is 1st optical disc, 2nd internal HDD and 3rd is external device. All options in this screen I can change.
Exit menu has 5 options, Exit Setup, Get Default Values, Discard Changes, Save Changes, Shutdown. Non of them have multiple options if you select any of them and press enter they do what they mean apart from shut down as the machine will still not fully turn off without pulling the plug with the battery out. I have selected Default values figuring it will reset the BIOS as you requested.
Today when I booted the laptop using my circular motion trick on the laptop keyboard and tapping F2 on the USB keyboard I got into the BIOS fine and everything is stable in the BIOS as in when I select an item that can be changed it hasnt kept scrolling through its choices constantly making it a lucky dip when you hit enter. I can actually use the USB keyboards + and - keys to the option as required.
Please every one who reads this read it fully before asking questions as I only type with 1 finger so it has took an age to do and I have had the problem laptop in front me and have typed exactly is selected as it is screen by screen.
Thank you,
Jim.
