Front VIAO word does not light up anymore took off panel and see LED that does not light up the blue front word "VAIO" need to know how to change and where power comes from on mother board for light?
Obviously the question was not answered correctly. I don't know how well you are versed into taking things apart, but here we go. First you need to unplug Sony. You need to remove the I/O panel on the bottom of the case after removing the front panel. Remove the on/off switch and remove the two lights adjacent to it. You gently pry apart the tabs on the back of the bulbs and pull the lights out from the back out of retainer. Do the same with the light that is burned out. Carefully cut or break the two cable ties and remove complete wiring harness. You need to remove the side Panel (right side looking from the front). Remove the air tunnel pieces (2 of them), The cable that needs to be unplugged from the motherboard. it is the very first along top edge from the left. It is yellow. Open the 2 tabs that hold all wiring down the front (you will see these just in front of CPU fan and behind front grill. Remove the harness. I do have the number in front of me but you can take the harness to Radio Shack and they can give you the correct one. Cut the old bulb off as close as possible. Solder the new one on and reverse the steps to reinstall. Once harness is plugged back onto motherboard, you can test by plugging power cord in and pushing power button. Make sure none of the wires are touching each other or any metal. Put it all back together and you will have blue light (light is not blue, plastic in front of it is). OR you can just use it without that light as it serves no purpose to be pretty and no one but you will know the difference. By the way I refurbish, repair, etc. nothing but Sony PCs. You also may be able to find a replacement harness but they are scarce. Hope this help. OH, the power supply or motherboard has nothing to do with this bulb working or not. If the other two (power on and hard drive activity) work, the bulb only, is bad.

you can upgrade the CPU without changing the motherboard if the CPU is compatible with the motherboard, you have to buy an Intel processor since the motherboard is Intel. Log on to http://www.intel.com/

Hello there... Check your PC's volume. You may or someone in your household has accidentally muted it. Unmute it or increase its volume (if you can't find the audio icon in the taskbar, proceed to the control panel - it's there), it maybe too low. Hope this helps... Ai :)

The light source for the front Vaio emblem is an LED, the LED is being supplied voltage but does not light. So it is definatly a bad LED the question now is What is the replacement part No. for a new LED. Is there a wiring diagram for this computer ?
