I have a 2002 holden rodeo 3ltr turbo diesel that just stopped while driving how do you check to see if it is the pump or just blocked lines

Just to start with the basics make sure their is fuel in it ... somtimes when these trucks run out of fuel you have to add more then 5 gallons to get the fuel high enough to run over the internal cup that the fuel pick up tube sets in 1 or 2 gallons is not enough to do this . Then have some one try starting the truck while you remove the fuel cap and put your ear to the fill tube for the gasoline you should be able to hear the fuel pump run because it is located inside the fuel tank . If you don't hear the pump running you can try hitting the bottom center of the fuel tank with a heavey blunt object ( block of wood ,Baseball bat ect.) nothing that has a sharp edge . Do this while some one is cranking ( turning the key to start the truck) this somtimes will free the pump up and it will start working again . If it starts then you know the pump is bad . Somtimes when the pump frees up they work again for weeks or months but it not good to take that chance and break down on the highway. Replace the pump and filter .

I cant hear anything without earphones

If you have left the earphone plugged in to the laptop for a long time, this may have bent the contacts in the socket, and stopped the speakers from working.

My webcam has stopped working

Normal 0 Probably has corrupt driver.
Try disconnecting the Camera from the USB port and reinstall the CD or Downloaded software program. When the program asks you to connect the camera to the USB port, do so and it should work.
Hope this helps. Bud

Power on green light is on but no sound when speakers are hooked up

Light is on so suggests power, earth and remote turn on cable all ok. Now you just need to test the RCA signal and the AMP output. I take it you have used low level RCA as the input from the head unit? (two cables usually red n white although can somtimes be other colours) best way is with substitute amp n speakers etc although can be done with osciliscope or headphones. Once it is established the RCA signal is fine then you can check the speakers from the amp. disconnect them at the amp and put each of the two wires briefly to a battery, any battery will do e.g. 9v PP9 or 1.5v AA etc you should hear a pop from each speaker as you do it. that proves the speakers and wiring to them.
If there was no signal from the RCA the cables may be bad - requires testing from head unit to amp
failing that the RCA output may be reduced or turned off via a menu in the head unit
Or the RCA output from the unit may be knackered.

Sorry its a bit long hope it helps

The static is probably coming from the computer sound card itself. Turn the volume down on the computer mixer it should limit the static you are hearing.

My Touch pad does not work, can someone help? the touchpad suddenlly stops working while i was using it

try to remove battery. Turn on you computer without battery. battery can cause keyboard and mouse not working.
also make sure your touchpad is enable by using fn+F7
if this is still doesn't work, it's mean your touchpad itself is bad.
