If the sound device does not have a disc, contact the manufacturer or download the drivers from the manufacturer's website. To check the system for sound devices, go to "Start," "Control Panel" and "Sound and Audio Devices." The primary sound device will be shown in the top of this window. Step 2 Check the "Audio Devices" properties window for muted volume or the volume bar set to minimum. Either of these will cause the sound to not work.

A list of hardware will be displayed. Audio devices are under "Sound Video and Game Controllers."

Connecting External device to TV?

There are many external devices like
laptop,pc,computer,dvd,vcd,sat rec,player etc etc.
Which you can connect to your tv.
Connecting this up will be easy. What you do is get a yourself a set of the right, for your setup, cables. That uses EITHER one of the formats, of these described, below. You will need, either, a THREE way Cable, or three separate " Coaxial Cored" Cables with RCA PLUGS on them. Colored Yellow, (Video) Red, & White. (Audio) AV. OR If you haveSCART Connection Sockets, it's a big Black Socket at rear of unit(s), you get a SCART Cable.& It's all inside. Now some units, use a standard calledComponent Video, that uses, a Green, Red, & Blue Plugs. Also we have with the "Component Video" it is marked "Y" "Pb" & "Pr" these simply go color to color at BOTH ends, this is where the Red, Green, & Blues, colored Ends, of the Wires, goes, remembering that this is ALL only Video. With this method, you still must use the AV, red & White, Audio, Inputs to get the "Sound" into the unit, with the Component setup, you will also ,need, Two more Cables, for the AV Audio. these are, Red &White.(So with Component Video there are 5 Cables/Plugs in all). In any event ALL Cables go Color to Color, at each end, plugging into the corresponding Colored RCA Jacks, on either machine, or VCR or TV. Now if you have SCART, then it simply plugs in only one way. It is that simple. So connect up with the leads your set uses, and select the correct "Input" from TV/Remote, it is NOT on a "Channel" it will be on AV, AUX, and Press "Play" on VCR/DVD whatever.... should be all go.

Right, well, IF your TV has a DB15 Female Plug on it then you CAN, connect it up and it will work, as a second "Monitor". OR If the laptop, has a "Composite Video" a Yellow RCA socket, then you can, connect to the TV's Composite IN. & it will be a second monitor. Otherwise you cannot, the VGA signal is NOT compatible with a TV's input. SOME cards have a connector that plugs into the DB15 and to the TV, but they are "Special". In saying that though you can "Micky Mouse" things together and get an output, but it real poor quality, and disappointing results, there are various posts on the net about doing this if you wish. 
Remember DRIVERS, you also need the drivers installed & setup correctly in order for the hardware to work. As a tip, When connecting to a TV, always connect like this......First, plug all cables into TV's correct Video input(s). Connect up the Sound, plug all cables into laptop, turn TV ON. NOW, start the laptop, you should now soon see the an image.
NOTE: Some laptops & other devices, have HDMI out, sometimes, the AUDIO is not passed through, the HDMI cable, & the Audio must be run from Audio/Line OUT on laptop to AV IN on TV.Also some laptops have a socket that a multi-way 4/5/6/7 pins. A connector plugs into this, you then can connect to these connections, as you would normally. Also we have "Component Video" marked "Y" "Pb" & "Pr" these simply go color to color at BOTH ends, this is where the Red, Green, & Blues, colored Ends, of the Wires, goes, remembering that this is ALL only Video. With this method, you still must use the AV, red & White, Audio, Inputs to get the "Sound" into the unit

At the rear or side of the PC there should be either or both of a 15 Pin DIN Plug, HDMI socket. or a Yellow RCA or 4 -7 pin DIN. Now IF these are present then YES you can connect to a TV. Now some TV's have a connector a DB15 MALE, so that the cable from the PC to the TV, is DB15. this plugs in directly, with appropriate DB15 cable. This, however, will ONLY take the VIDEO to the TV, Audio is delivered via the "Audio Out" Jack on PC, and Plugged into the AV Sockets on the TV, with a dual cored coaxial cable, they are Red & White. Some PC's also have a Yellow RCA Connector, OR a 4 -7 Pin DIN Socket, that requires a Special Adapter Cable (That generally came with the unit, and are colored and marked as to output) to use, for Video/Audio Out to TV. This signal is Composite or SVHS Video & Stereo Out. This connects up TO the TV's Composite/SVHS input Jacks and the Red & White Audio IN, RCA Jacks, &/or DIN SVHS socket. Also we have "Component Video" marked "Y" "Pb" & "Pr" these simply go color to color at BOTH ends, this is where the Red, Green, & Blues, colored Ends, of the Wires, goes, remembering that this is ALL only Video. With this method, you still must use the AV, red & White, Audio, Inputs to get the "Sound" into the unit
First you need to know if your PC can output to a TV. Then you need to get the adapter & cables that connect the PC to the TV. Then you need the correct TV drivers installed for your video card. When they are all installed, you need to "Enable" that Monitors, the TV's, Desktop. You need to set either a "Cloned" display or "Spanned, Extended Desktop". Go to "Display Settings" Now ensure the TV/Monitor connected has the correct input/output display settings. Adjust the screens resolution via the resoloution "Slider", it is best to start with, 800x600 32 bit color. or even lower. and once working OK, THEN increase to max resolution, your TV can handle, find out from manual. Once it is all connected up. It should all just work great. Now, from then on, &, to get it to work every-time, the process is. Turn everything OFF. Connect the leads between PC & TV, Turn the TV, ON. Then, startup the PC up. It should "Detect" that it has TWO "Monitors" ie: One Monitor & One TV/Monitor, & you should see your desktop appear after a bit. Now you have screen 1 & screens 2. Now, if you are using "Cloned" mode, then whatever is displayed on the Master monitor, will be displayed on the TV. If you used Spanned, mode, in this mode, however, you will have to."Drag" the Video window, over to the TV, and it is though, you have one "Big Desktop". Now IF using Nvidia or ATI then BOTH of those have thier OWN, Control Panel, this, all then can make it all a lot easier to do it. So I would suggest that this method be used. But if you get stuck, or just want to do it by hand, then the the "By Hand" method is the only way.There is a great program called MultiMon, this allows great control over dual displays, and is well worth installing.


This above mentioned details will help you to get your external device connected to your television.

How to by pass BIOS on Toshiba laptops?

This details will guide you to do the following:---
Key Disk for Toshiba laptops. Some Toshiba notebooks allow to bypass BIOS by inserting a "key-disk" in the floppy disk drive while booting. To create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it (if it's not formatted yet), then use a hex editor such as Hex Workshop to change the first fwe bytes of the second sector (the one after the boot sector) and set them to 4B 45 59 00 00 (note that the first three bytes are the ASCII for "KEY" :) followed by two zeroes). Once you have created the key disk put it into the notebook's drive and turn it on, then push the reset button and when asked for password, press Enter. You will be asked to Set Password again. Press Y and Enter. You'll enter the BIOS configuration where you can set a new password. 
This detail /procedure will help you out.
