Re: not booting up and no bios display when turned on
This can be a number of parts in your computer.
First, it could be the laptop monitor. Ty connecting it to another one, see if that helps.
Secindly, it could be either the graphics card or the motherboard. If you don't know anyone who knows how to switch those arund and has spare parts, or you can yourself, take it to a computer store and ask them to test some parts.
One of these should solve the problem, and then you will know which part is broken and needs to be replaced.

You can do this:
1. Remove the hard drive and turn on the laptop. If the laptop's screen displays the BIOS, then replace the hard drive with a good working hard drive,
If it the laptop screen does not display anything, then:
2. Test it using an external monitor.
- If the external monitor blank too, then there is something wrong with your laptop's GPU and or motherboard (you need to replace the motherboard)
You may have killed your laptop. BIOS have little to do with an OS like Windows, Linux, etc. The display issue is the culprit. Using another computer go to Toshiba website a get the current BIOS for your laptop. Are you able to access the BIOS at all? (press Del during bootup? to enter the Config screen (looks like DOS)
o enter the bios Press DELETE or F12 or the key displayted on the screen saying Press key to enter setup. Its the first screen you see when you turn the system on, if you see a logo you can press ESC to go to the display screen with the information..
the JMP is a 3 pin JMP close to the processor. The defaults should be fine, so you dont need to adjust the jmp settings.
What version of Windows are you running? Can you get the computer display to stay on in the BIOS setup screen? If so, you may have a missing or corrupted file in the operating system. A good check is to download a copy of Ubuntu Linux to a flash memory stick and set up the computer to boot from that.
If the display blacks out even in BIOS setup, try shining a flashlight on the screen at an angle. If you see the log-in screen or whatever around the light spot (it will be faint), then you have a backlight failure. The screen has a couple of cold-cathode fluorescent lamp (CCFL) tubes behind it driven by a high voltage inverter. If one of the tubes is bad, the inverter will turn off after a few seconds - just long enough to get to the boot program in a normal startup. Watch carefully when you turn on the computer - if the top or bottom is dim, flickering, or pink-colored, you definitely have a bad tube.
CCFL tubes are $12-$20, depending on the display model. Replacement requires considerable soldering expertise, as well as the mechanical ability to disassemble the display panel without breaking anything.
have you tried installing or running the drivers disc for your laptop right after the windows installation without restarting it first? that might do the trick... it's either the driver for your laptop's board/ chipset or the vga driver...
If your BIOS loads properly you have some display in your screen like text. But when you turn on and nothing readable on the display then you have problem in the BIOS. Try to flush updated bios in sony website. Recovery disk is only applicable if the system will display "Cannot find boot disk" or bios is properly loaded before you can boot from CD. If you wish you can boot it with Norton Ghost 12 Recovery Disk.
